Difference between a Proforma Invoice & Tax Invoice

Proforma Invoice

A proforma invoice is a preliminary document issued by a seller to a buyer that provides an estimate of the costs and terms associated with a potential sale. It serves as a formal quotation outlining detailed information about the goods or services to be provided, including prices, quantities, and terms of delivery and payment.

Although it looks similar to a commercial invoice, a proforma invoice is non-binding and does not serve as a request for payment. Instead, it is used to establish the buyer’s intent to purchase and to facilitate processes such as customs clearance, budget approval, and financing arrangements.

Commonly used in both domestic and international trade, it helps both parties ensure mutual understanding and agreement before finalising the transaction.

To ensure clarity and avoid misunderstandings, it's important to include specific information in the proforma invoice. Here's a breakdown of the key components that should be included:

1. Header:

• Title: The header of the proforma invoice should clearly indicate that it is a "Proforma Invoice" to distinguish it from other types of invoices.

A proforma invoice is issued before the actual sale takes place. It serves as a preliminary agreement or a formal quotation, providing the buyer with an estimate of the costs and terms associated with the proposed transaction.

      2. Non-Binding: 

Unlike a commercial invoice, a proforma invoice is not legally binding. It does not constitute a demand for payment and does not obligate the buyer to purchase the goods or services or the seller to deliver them.

      3. Detailed Cost Estimate: 

The proforma invoice provides a detailed breakdown of the costs involved, including the price of goods or services, taxes, shipping fees, and any other applicable charges. This helps the buyer understand the total financial commitment.

      4. Terms and Conditions: 

It outlines the terms and conditions of the proposed sale, such as payment terms, delivery dates, and any warranties or return policies. This ensures both parties are clear on the expectations before finalizing the transaction.

      5. Used in International Trade: 

In international transactions, a proforma invoice is often required by customs authorities to declare the value of goods for customs clearance. It can also be used to obtain import licenses, letters of credit, or pre-shipment inspections.

      6. Facilitates Budget Approval:

 Buyers can use the proforma invoice to seek internal approval for the purchase or to secure financing. It serves as an official document that justifies the expenditure before the actual sale occurs.

      7. Validity Period: 

Proforma invoices typically include a validity period, indicating how long the quoted prices and terms are valid. This allows the buyer to make decisions within a specified timeframe.

      8. Comprehensive Product/Service Information:

 It includes detailed descriptions of the goods or services being offered, along with quantities, unit prices, and any applicable discounts. This ensures clarity and helps prevent misunderstandings.

      9. Facilitates the Sales Process: 

The proforma invoice acts as an initial step in the sales process, helping to initiate discussions and agreements on the terms of the sale before the final commercial invoice is issued.

      10. Customs and Legal Compliance:

 It often contains information required for customs and legal purposes, such as HS codes and tax identification numbers, making it an essential.

Purpose of a Proforma Invoice

1. Providing Cost Estimates:

In international trade, proforma invoices are used to provide customs authorities with an estimate of the value of goods being imported or exported. They are also used to obtain import licences, letters of credit, or pre-shipment inspections.

     5. Initiating the Sales Process:

The proforma invoice serves as a starting point for the sales process, allowing the buyer to confirm their intent to purchase and the seller to prepare for the transaction. It helps prevent misunderstandings by clearly outlining what will be provided and at what cost.

     6. Avoiding Disputes:

By clearly laying out the details of the transaction in advance, a proforma invoice helps prevent potential disputes between the buyer and seller. Both parties can review and agree on the specifics before the final commercial invoice is issued.

• Example: A company presents a proforma invoice to management for approval before proceeding with the purchase of new equipment.

   4. Arranging Payment or Financing

• Use: A proforma invoice helps buyers arrange payment or secure financing, such as loans or lines of credit, before making a purchase. It provides all the necessary information about the transaction, helping banks or financial institutions assess the funding needed.
• Example: A buyer uses a proforma invoice to apply for a letter of credit from a bank to pay for an international shipment.

   5. Setting Terms and Conditions

• Use: The proforma invoice clearly lays out the terms and conditions of the sale, such as delivery dates, payment terms, and shipping methods. This ensures that both the buyer and seller agree on the terms before proceeding with the transaction.
• Example: A seller issues a proforma invoice outlining the delivery timeline for custom-manufactured goods, which the buyer reviews and approves.

   6. Avoiding Disputes

• Use: By providing detailed descriptions of the goods or services, quantities, prices, and terms, a proforma invoice helps prevent misunderstandings and disputes between the buyer and seller. It allows both parties to review and agree on the transaction before it is finalised.
• Example: A buyer and seller use a proforma invoice to confirm the exact specifications and costs of a large order, reducing the likelihood of disagreements later.

   7. Initiating the Sales Process

• Use: A proforma invoice serves as a starting point for the sales process. It helps the seller secure the buyer's intent to purchase and acts as a precursor to the final commercial invoice, which is issued after the goods or services are delivered.
• Example: A company provides a proforma invoice to a client who is interested in purchasing services, allowing them to review costs and terms before signing

   8. Documentation for Pre-Shipment Inspections

• Use: In some international transactions, a proforma invoice is required for pre-shipment inspections to ensure that the goods meet the buyer’s specifications before being shipped.
• Example: A company exporting machinery includes a proforma invoice as part of the documentation for the pre-shipment inspection process to verify compliance with the buyer's requirements.

   9. Negotiating and Finalising Terms

• Example: A buyer and seller use the proforma invoice to adjust shipping terms before agreeing on the final sale.

When to use a proforma invoice

A proforma invoice is used in various situations to provide an initial estimate or formal quotation before the actual transaction takes place. Here are common scenarios when a proforma invoice should be used:

   1. Before Finalising a Sale

• Use Case: A proforma invoice is often issued when the buyer requests a detailed estimate of the goods or services before committing to the purchase. It helps both the buyer and seller agree on the costs, quantities, and terms before finalising the transaction.
• Example: A manufacturer sends a proforma invoice to a customer who is considering placing a large order but needs to review the cost details first.

   2. In International Trade

• Use Case: In international transactions, a proforma invoice is commonly used for customs clearance, import licences, and other trade-related processes. It provides a preliminary declaration of the value of goods being shipped and helps in obtaining letters of credit or import approvals.
• Example: An exporter sends a proforma invoice to an overseas buyer, which is then used to arrange customs documentation before shipment.

   3. When Seeking Budget Approval

• Use Case: Proforma invoices are helpful when a buyer needs internal approval to make a purchase. The document provides a formal cost estimate that can be reviewed and approved by management or finance departments.
• Example: A company preparing to purchase new equipment uses a proforma invoice to get financial approval from their accounting team.

   4. To Facilitate Prepayments or Financing

• Use Case: A proforma invoice is often issued when the buyer needs to secure financing or arrange for payment, such as a loan or letter of credit, before the sale is completed.
• Example: A buyer uses a proforma invoice to apply for a bank loan or letter of credit needed to pay for a large order.

   5. When Custom Orders Are Involved

• Use Case: For customised goods or services, a proforma invoice is used to ensure the buyer understands and agrees to the costs, specifications, and timeline before the seller proceeds with production or service delivery.
• Example: A company issuing custom-made products sends a proforma invoice to confirm the buyer's requirements and costs before starting production.

   6. To Clarify Terms and Conditions

• Use Case: A proforma invoice is used when the seller needs to provide the buyer with a clear understanding of the terms and conditions of the sale, such as payment terms, delivery timelines, and other obligations, before the actual transaction takes place.
• Example: A vendor sends a proforma invoice to ensure the buyer is aware of and agrees to the shipping terms and expected delivery date before finalising the sale.

   7. To Avoid Disputes

• Example: A supplier provides a proforma invoice to a customer to ensure the customer is aware of all charges and specifications before proceeding with the order.

  8. Before Providing Goods or Services for Trial:

•  Use Case: A proforma invoice may be issued when the buyer is given a trial period or sample of goods or services before making a full purchase commitment. It outlines potential costs, helping the buyer make an informed decision.
•  Example: A software company issues a proforma invoice before providing a free trial to outline the cost if the buyer chooses to continue with the service.

Limitations of a Proforma Invoice

1. Not Legally Binding:

• Limitation: A proforma invoice is not a legally binding document; it cannot be used as an official demand for payment or some sort of legally enforceable agreement. That is to say, neither party is obliged to fulfil the conditions set out.
• Impact: Since it is nonbinding, the final terms and prices or conditions can change, and misunderstandings or disputes can arise should there be differences in expectations.

2. Not a Demand for Payment:

• Limitation: A proforma invoice is only an estimate or quotation and is not used to request payment. It does not serve as an official record for accounting or tax purposes.
• Impact: The buyer cannot make payments based on a proforma invoice, and it cannot be used for financial reconciliation or to track accounts receivable.

3. Not for Tax Purposes:

• Limitation: A proforma invoice is neither legally binding nor final and, therefore, cannot be used for tax reporting, claiming tax credits, or any official financial documentation.
• Impact: Where tax reporting is important, a business must issue a commercial or tax invoice in a formal manner to show their compliance with the law.

4. Risk of Confusion:

• Limitation: It looks very much like a commercial invoice, and they can sometimes get confused with one another. The buyer may mistakenly interpret the proforma invoice as a demand for payment, which leads to confusion.
• Impact: This may cause a hold-up of the payment or of the processing if the buyer mistakenly assumes it as the final invoice.

5. Estimates May Change:

• Limitation: A proforma invoice gives an estimated cost that might change at the time when the actual invoice is issued. It may be subjected to changes in price, tax, shipment, or terms of delivery.
• Impact: The buyer may be let down if the final cost is different from what was given earlier on. This might lead to a rethink or some kind of delay.

6. Limited Use for Financial Reporting:

• Limitation: Though it is not a real invoice, this proforma invoice does not reflect accurate revenues or expenses, and for all these reasons mentioned above, proforma invoices cannot be used for financial statements, cash flow management, or profit and loss reports.
• Impact: Since businesses use proforma invoices for financial reporting on the issuance of a formal invoice, it renders null the proforma invoice and needless.

7. No Proof of Ownership:

• Limitation: There is no legal evidence of the title of goods transferred by a proforma invoice. Since it is a document before the transaction, it cannot be evidence that the buyer owns the goods or services.
• Impact: Buyers and sellers have to issue and depend on commercial invoices or other documents that are legally binding, which can be used to show evidence of purchase or ownership.

8. Lack of Finality:

• Limitation: A proforma invoice is never fixed but is changed until the final commercial invoice is provided. If there would be some changes in the quantities, price, or terms of services, it must lie in the final invoice, which brings about discrepancies sometimes.
• Impact: Lack of Finality: It may cause uncertainty for both parties especially when such terms like dates of delivery or pricing need to get finalised.

Tax Invoice

A tax invoice is a document in respect of a sale of goods and services, which are subjected to taxation, issued by a seller to the buyer legally. It forms part of a transaction and usually serves as the basis for tax reporting, especially for VAT (Value Added Tax) and GST (Goods and Services Tax) purposes. The tax invoice is a documentary evidence for such a sale, covering the description of goods or services sold, the amount to be charged for tax, and due dates for the payment.

Components of a Tax Invoice

A tax invoice would contain certain elements that would make it valid from a legal or regulatory point of view, especially toward tax compliance. The following are the essential elements of a tax invoice:

1. Title:

• Shipping Method: Mode of transportation - air, sea, road

13. Taxable and Non-Taxable Items:

• If an invoice has items that are taxable as well as those that are not taxable, these need to be set apart and should be clearly identified. The invoice should stipulate which items come within the tax ambit and which do not.

14. Discounts Available (If Any) :

• Discounts, if any availed on the invoice, should be shown clearly, stating the amount of discount and deduction on the subtotal.

15. Signature or Authorization:

• In certain cases, there may be a requirement for a signature or sometimes even an electronic authorization to make a tax invoice valid, which basically occurs on paper-based systems. This may also involve an electronic signature for the digital invoices.

16. Additional Notes or Legal Disclaimers:

• Any other information that may be attached to the transaction which may involve return policies, warranty, or even legal disclaimers of tax compliance.

Key Features of a Tax Invoice

1. Legally Binding Document:

A tax invoice is, by law, a required document in the case of a transaction related to sales of goods or services where tax has been deducted. It serves as proof of a transaction and, as such, is used both for legal and tax-reporting purposes.

2. Detailed Tax Information:

The tax invoice stipulates the type of tax applied, such as VAT or GST, the total amount due from the taxpayer as tax, and also the applicable rate. All this helps in bringing transparency that contributes to accurate tax reporting and facilitates complete compliance with the laws that concern taxation.

3. Request for Payment:

Whereas the proforma invoice is not, in itself, a bill for products or services provided, a tax invoice represents a demand for payment when those self-same goods or services have, as a matter of fact, been supplied. It should indicate what the total is transparently and with the cost of items involved, adding all the different kinds of taxes applicable.

4. Detailed Breakdown of Goods/Services:

It contains a detailed statement of goods or services provided, including their description, quantity, unit prices, and total amount for each type. This helps the two parties to know what they will have paid for or achieved.

5. Invoice Number and Date:

The unique invoice number helps to track the invoice regarding accounting and tax purposes. The date of issue is also provided to show when it was issued.

6. Seller and Buyer Information:

The tax invoice should provide complete details of both the seller and the buyer, specifically their names, addresses, and identification numbers for tax purposes such as VAT or GST numbers. This is very crucial information during taxation, especially in B2B transactions.

7. Payment Terms:

The invoice details the terms of payment-when it is due and in what forms, for example bank transfer and credit card. This in return shows when and how the buyer should make the payment.

8. Amount Payable :

Consisting of the pre-tax amount together with the total tax to be shown in total. It is the final amount that shall be paid by the buyer.

9. Used for Tax Reporting and Compliance:

Tax invoices are significant among businesses in reporting to the government on a business, especially in reporting Value Added Tax or Goods and Services Tax. Any buyer can claim tax credits using a tax invoice, while on the other hand, the seller would use this to compute any taxes that he will have to pay.

10. Input Tax Credit Facility:

The tax invoice in business-to-business transactions supports the buyer in claiming input tax credits on the taxes paid. This is, in fact, essential in the VAT and GST systems, wherein businesses are allowed to offset the taxes already paid on purchases against the collected taxes arising from sales.

11. Clearly States Taxable and Non-Taxable Items:

If there is at least one of both taxable and non-taxable goods or services, the invoice clearly distinguishes between them to help buyers understand what happens in respect of each item regarding taxation.

12. Signature or Authorization (Optional):

In some jurisdictions or for certain kinds of transactions, a signature or even digital authorization may be issued to validate the tax invoice.

Purpose of a Tax Invoice

1. Request for Payment:

• A tax invoice serves as a formal request for payment from the buyer. It provides a detailed breakdown of the goods or services delivered and the total amount payable, including any applicable taxes. It ensures that the buyer knows the exact amount owed and the payment terms.

2. Legal Proof of a Sale:

• A tax invoice acts as legally binding documentation of the sale of goods or services. It serves as a record for both the seller and buyer that a transaction occurred, outlining the details and amounts involved. This is especially important in the case of disputes or for legal purposes.

3. Tax Reporting and Compliance:

• The tax invoice is used for tax reporting by both businesses and tax authorities. Sellers use tax invoices to calculate the amount of tax they need to remit to the government, such as VAT (Value Added Tax) or GST (Goods and Services Tax). Buyers, particularly businesses, need tax invoices to claim tax credits for the taxes they have paid on purchases.

4. Facilitating Input Tax Credits:

• In many tax systems, such as VAT or GST, businesses can claim input tax credits on the tax they have paid for goods and services. A tax invoice provides the necessary documentation for buyers to claim these credits, allowing them to offset taxes paid on purchases against taxes collected on sales.

5. Ensuring Transparency and Accuracy:

• A tax invoice provides a detailed and itemised list of the goods or services supplied, including the tax rate and amount charged. This transparency ensures that both the buyer and seller are clear about the transaction details, reducing the risk of misunderstandings or disputes.

6. Record-Keeping:

• For both buyers and sellers, tax invoices serve as important financial records. They are essential for tracking sales, managing accounts payable and receivable, and maintaining accurate financial records for audits or internal reviews.

7. Customs and International Trade:

• In international trade, tax invoices are often required by customs authorities to determine the applicable taxes or duties on imported goods. They serve as proof of the value of goods being traded and are used to ensure the correct taxes are applied during customs clearance.

8. Proof of Ownership and Transfer:

• A tax invoice acts as proof that the buyer has purchased and taken ownership of the goods or services. It provides legal documentation that can be used in case of warranty claims, returns, or other future business dealings.

9. Facilitating Payment Terms:

• A tax invoice outlines the payment terms, including the due date and accepted payment methods, ensuring that the buyer understands when and how to make the payment. It sets the expectations for both parties regarding the completion of the transaction.

• Use: A tax invoice is considered a formal demand for payment by the buyer. It provides a summary of the total amount due, including the price of goods or services, taxes, and all other charges.
• Example: A supplier provides a tax invoice to a buyer regarding delivery made by him, demanding payment within a particular period.

2. Tax Reporting and Compliance:

• Use: A tax invoice is necessary in reporting and compliance purposes from the buyers and sellers concerning their tax obligations.

• Example: A business uses tax invoices to report its obligations concerning value-added tax to the government at the end of the tax period.

3. Claiming Input Tax Credits:

• Use: In value-added tax and goods and services tax systems, input tax credits are claimed by businesses with the assistance of a tax invoice. They can set off taxes paid on purchases against the taxes collected on sales for arriving at their tax liability.
• Example: A business buying raw materials may claim a VAT credit for the amount it paid to buy the material using the tax invoice provided by its supplier.

4. Legal Proof of a Transaction:

• Use: A tax invoice falls into the category of a document in that it provides assurance that there indeed was a purchase made and at the same time what was sold, at what price, and with what tax applied.
• Example: Tax Invoice is used in case of dispute or audit purposes for proving that the seller provided goods or services and the buyer paid for them.

5. Record-Keeping and Accounting:

• Use: Tax invoices are relevant to keeping books of accounts accurately. They would help a business entity to keep a tab on its sales, purchases, taxes payable, and taxes paid that eventually enable correct financial reporting and management.

6. Customs Clearance of Cargo in International Trade:

• Use: Tax invoices are used by customs authorities when international trade is affected in determining the applicable taxes or duties imposed on imported or exported goods. This type of invoice helps to assess the value of goods for purposes of taxation.
• Example: An importer presents a tax invoice at customs to determine the taxes or duties owed on imported goods.

7. Ensuring Payment Terms and Conditions:

• Use: A tax invoice states the terms of payment that are due, inclusive of the date and modes of payment accepted. This will give clarity between the two parties, the buyer, and seller, on when or how the payment should be made.
• Example: The seller puts, "Payment due in 30 days" in the tax invoice with the intention of stating the due dates of payments to the buyer.

8. Tax Deduction Evidence:

• Use: Tax Invoice - Evidence for tax deductions of expenses of a business. Expenses on services or goods purchased to operate businesses could be deducted from the income to arrive at the taxable income.

9. Verification for Audits:

• Use: Tax invoices are, therefore, used as proof of transacting during financial or tax audits to support businesses in proving the charge and payment of the correct amount of tax.
• Example: A business may generate tax invoices in the event of a tax audit as proof of taxes paid correctly for the year.

10. Customer Returns or Warranties Support:

• Use:The tax invoice may serve as proof of purchase should the buyer need to return goods or make a claim for warranty service.
• Example: The customer would produce a tax invoice showing when and how much he paid for a defective product.

When to use a Tax Invoice

1. When Selling Goods or Services Subject to VAT/GST:

• Use Case: A tax invoice must be issued when a sale of goods or services is subject to VAT (Value Added Tax) or GST (Goods and Services Tax). This is especially important in business-to-business (B2B) and business-to-consumer (B2C) transactions.
• Example: A retail store sells products to a customer and issues a tax invoice showing the total amount including VAT.

2. When Providing Services:

• Use Case: If a service provided by a business is taxable under the relevant tax laws (e.g., VAT or GST), a tax invoice must be issued to the client detailing the charges and applicable taxes.
• Example: A consulting firm provides services to a client and issues a tax invoice showing the service fee plus GST.

3. For Business-to-Business (B2B) Transactions:

• Use Case: In B2B transactions, businesses need tax invoices to claim input tax credits. A tax invoice provides the necessary documentation for businesses to deduct the taxes they have paid on purchases.
• Example: A manufacturer purchases raw materials from a supplier and receives a tax invoice to claim input tax credits for the VAT paid.

4. When Exporting Goods:

• Use Case: In international trade, tax invoices are often used for customs clearance purposes, detailing the value of goods and the taxes applied. Exporters may also be required to issue tax invoices to overseas buyers, even if the goods are exempt from domestic taxes.
• Example: A company exports machinery and issues a tax invoice for the value of the goods to help facilitate customs processes.

5. When Collecting Taxes:

• Use Case: If a business is registered to collect VAT, GST, or sales tax, it is legally required to issue a tax invoice whenever taxable goods or services are sold.
• Example: A construction company provides services for a client and must issue a tax invoice showing the VAT collected on the work completed.

6. When Offering Goods or Services on Credit:

• Use Case: When goods or services are provided on credit, a tax invoice is issued to document the amount owed, including taxes. This is important for managing accounts receivable and tax compliance.
• Example: A supplier sells products on 30-day credit terms and issues a tax invoice to the buyer, showing the amount due plus VAT.

7. When Claiming Input Tax Credits:

• Use Case: Businesses require a valid tax invoice to claim input tax credits on purchases. This allows them to deduct the taxes they paid on their purchases from the taxes they owe on their sales.
• Example: A business purchasing office supplies receives a tax invoice, allowing it to claim input tax credits for the GST paid on the supplies.

8. For Legal Compliance:

• Use Case: In jurisdictions where VAT or GST is applicable, tax authorities often require businesses to issue tax invoices for all taxable transactions to ensure transparency and tax compliance.
• Example: A restaurant issues tax invoices to customers for each sale to comply with local tax regulations.

9. When Customers Request Proof of Purchase for Tax Purposes:

• Use Case: Customers, particularly businesses, may request a tax invoice to record the transaction for their own accounting and tax reporting purposes. This is essential for claiming tax deductions or credits.
• Example: A business requests a tax invoice after purchasing software to record the transaction and claim the VAT paid.

10. When Handling Returns and Warranties:

• Use Case: A tax invoice is necessary when goods are returned or warranty claims are made. The invoice provides proof of the original purchase, including tax details.

Limitations of a Tax Invoice

1. Does Not Provide Proof of Payment:

• Limitation: A tax invoice is only a request for payment and not proof that the payment has been made. A separate receipt is needed in case of confirmation of the payment.
• Impact: After a tax invoice is issued by a seller, a receipt needs to be issued once payment has been received to complete the transaction. Confusion may set in if a business relies on a tax invoice as proof of payment.

2. Not Applicable to Budgeting or Pre-Sale Estimates:

• Limitation: Tax invoices must be issued after the sale is consummated or after goods/services have been provided; they cannot serve as any pre-sale estimate or quotation.
• Impact: There exists a number of situations in the real world where one has to use other forms of documents, such as proforma invoices or quotations, to give estimates of costs before the actual sale is made.

3. Requires Strict Compliance with Tax Laws:

• Limitation: Tax invoices are restricted through legal conventions and taxation laws in particular, down to the very detail of their tax information, such as value-added tax or goods and services tax. Non-conformity in the form, the amount of tax, or lack of any information might result in some complaints from the taxation authority.
• Impact: Firms are meant to adhere to the actual accuracy of the tax invoices, which could lead to strict internal controls and accounting systems that would enable them to avoid certain penalties and audits.

4. Limited Use in International Trade:

• Limitation: Though the tax invoices carry the basic information in domestic transactions, the same is grossly insufficient in case of international trades, where the documentation required encompasses a commercial invoice, customs declaration, and so on.
• Impact: In cross-border transactions, businesses typically require other documentation, such as a commercial invoice, to meet the respective customs requirements and deal with import/export duties, thus severely restricting a tax invoice for international trade.

5. Does not facilitate price negotiations:

• Limitation: It is a final document containing the agreement of sale; therefore, price negotiation cannot be conducted with it.
• Impact: Once tax invoices are issued, their use in the negotiation of price or terms is severely limited hence restricting business flexibility when trying to resolve disputes on price or discount. 

6. Time-Sensitive for Tax Credit Claims:

• Limitation: These buyers want to claim input tax credits on the taxes, such as VAT/GST. This usually happens within a limited time and for that particular period of taxation.
• Impact: Sometimes this means that, if one's business delays in issuing or receiving a tax invoice from another, there is a good chance the buyer may miss out on an opportunity to claim his input tax credits and bear losses as a result.

7. Mistakes May Get Your Tax Credits Rejected:

• Limitation: The inaccurate or incomplete tax invoice will be rejected by the authorities. Non-compliance can also be caused by the absence of a tax identification number, non-availability or incorrectness of the tax rates and description.
• Impact: In case the invoice is incomplete or incorrect, it would raise a problem for buyers concerning claiming input tax credits that may influence the relation between the supplier and the buyer as disputes arise, and penalties are imposed by the taxation department.

 8. Does Not Cover Payment Defaults:

• Limitation: A tax invoice demands the payment, but it does not guarantee that the buyer will issue the payment, nor does it make any provisions of law in case the buyer fails to make the payment.
• Impact: In case of default on the part of buyers concerning the payment of the amount, the owner has to make extra efforts, such as sending reminders or taking the case to the court of law, to retrieve the payment.

9. Storage and Record-Keeping Burden:

• Limitation: This typically burdens any business since most tax authorities require a business to retain tax invoices for some years in cases of auditing. This tends to result in a record-keeping burden on businesses that have many transactions.
• Impact: Organized, secure storage systems, either physical or digital, will be required to be invested in by the business for managing and retaining invoices. It adds to the cost and efforts of administration.

10. Restricted Utilisation for Internal Management Reporting:

• Limitation: A tax invoice reflects the tax-related aspects of the transaction and might not provide comprehensive information that could be useful for internal financial analysis or management reporting.
• Impact: In this respect, for comprehensive financial reporting, businesses have to depend on other kinds of documents, balance sheets, and income statements, which make tax invoices a limited utility for making internal business decisions.

Conclusion

Basically, the roles of both proforma and tax invoices are vital in business processes but serve different purposes. A proforma invoice may be considered an advance document that stipulates the estimation of goods or services to be supplied and is usually considered to be like an introduction or a precursor to the transaction itself. On the other hand, a tax invoice is legally issued after the sale and becomes important at the point of claiming payment and facilitating compliance with tax laws. While the proforma invoice does not bind parties and also does not have tax information, a tax invoice is considered one of the most important documents for tax reporting in that it helps businesses ascertain how much tax is due for payment or the amount of input tax credit they can claim. Knowing the difference between the two could be very helpful to any business for smooth transactions, good documentation, and compliance with tax regulations.
