When and Why Businesses Use Proforma Invoices?

Priyanka Babu

A proforma invoice is a preliminary commercial document issued by a seller to outline the details of a proposed sale before it is finalised. It usually includes product or service descriptions, quantities, prices, delivery terms, and payment conditions. Under UAE VAT law, a proforma invoice is not treated as a tax invoice and does not create a VAT liability on its own. It cannot be used for accounting entries or VAT reporting and is issued only for reference and confirmation purposes. 

The uses of a proforma invoice in the UAE include formalising quotations, supporting sales discussions, requesting advance payments, and facilitating export transactions. By clearly communicating commercial terms in advance, proforma invoices help improve transparency, reduce disputes, and enable a smoother transition to a valid tax invoice once the transaction is completed. 

What is a proforma invoice? 

A proforma invoice is a non-binding commercial document issued to present the proposed terms of a transaction before an actual sale takes place. Its primary purpose is to give the buyer a clear preview of pricing, quantities, delivery terms, and other commercial conditions, helping both parties reach an agreement before order confirmation. 

From a UAE legal and commercial perspective, a proforma invoice does not have accounting or tax validity. It is not recognised as an official sales document and cannot be used for revenue recognition, VAT filing, or input tax recovery. Instead, it serves as a reference document commonly used in trade, especially for approvals, negotiations, and export processes. 

A proforma invoice is optional, not mandatory under UAE regulations. Businesses can use it based on commercial need, particularly when transactions require advance clarity, customer approval, or pre-payment confirmation. 

When do UAE businesses use proforma invoices 

The uses of a proforma invoice in UAE businesses span multiple stages of the sales and trade cycle, helping communicate proposed transaction details before a legally valid tax invoice is issued. Proforma invoices are used to set expectations, obtain internal or customer approvals, and ensure clarity between buyers and sellers, particularly in transactions involving negotiations, advance payments, or exports. 

Proforma invoices in sales transactions 

Before finalising a sale, businesses often issue a proforma invoice to clearly outline the proposed commercial terms. This allows both parties to review and confirm details before committing to the transaction. 

  • Use before finalising a sale: Issued prior to order confirmation to avoid misunderstandings. 
  • Sharing pricing, quantities, and terms: Communicates product details, prices, discounts, delivery timelines, and payment terms. 
  • Internal approvals and customer confirmations: Helps customers obtain internal approvals and provides sellers with confirmation before issuing a tax invoice. 

Proforma invoices as quotations 

Proforma invoices are frequently used as structured and professional quotations, especially for B2B transactions in the UAE. 

  • Acting as a formal price quote: Serves as a detailed quotation with clear commercial terms. 
  • Validity period and pricing conditions: Specifies how long the quoted price remains valid and any conditions that apply. 
  • Customer acceptance before order confirmation: Once accepted, it forms the basis for raising a sales order or tax invoice. 

Proforma invoices for advance payments 

When advance payments are required, proforma invoices play an important role in communicating payment expectations. 

  • Requesting partial or full advance payments: Clearly indicates the amount payable in advance. 
  • Supporting advance payment receipts: Acts as a reference document when recording advance receipts. 
  • Link to advance tax invoices: While the proforma invoice itself does not create VAT liability, a tax invoice must be issued upon receipt of advance payment as per UAE VAT rules. 

Proforma invoices in export transactions 

In international trade, proforma invoices are a standard document used before shipment and contract finalisation. 

  • Use in international trade and customs processes: Helps buyers and authorities understand shipment value and terms. 
  • Supporting export pricing and shipment planning: Assists in logistics planning, freight estimates, and cost approvals. 
  • Role in letters of credit and trade finance: Often required by banks as part of documentation for letters of credit and financing arrangements. 

Proforma invoice and UAE VAT: Key considerations 

Understanding how proforma invoices interact with UAE VAT regulations is essential to avoid compliance errors. While widely used for commercial purposes, proforma invoices have a clearly defined role under UAE VAT law. 

Distinction between a proforma invoice and a tax invoice 

A proforma invoice is a preliminary commercial document and does not meet the legal requirements of a tax invoice under UAE VAT law. A tax invoice must contain specific mandatory details and is the only document recognised for VAT reporting and input tax recovery. 

VAT liability and proforma invoices 

Issuing a proforma invoice does not create a VAT liability. VAT becomes due only when a taxable supply is made or when an advance payment is received, not at the stage of issuing a proforma invoice. 

VAT treatment of advance payments 

When an advance payment is received against a proforma invoice, VAT becomes applicable at the time of receipt. In such cases, the supplier is required to issue a valid tax invoice for the advance amount in accordance with UAE VAT rules. 

Timing for issuing a tax invoice 

A tax invoice must be issued within the prescribed timeline once the supply is made or an advance payment is received. The proforma invoice serves only as a reference and must always be followed by a proper tax invoice for VAT compliance. 

Key details to include in a UAE proforma invoice 

Although a proforma invoice is not a legal tax document, including clear and complete information helps avoid confusion and ensures smooth conversion to a final tax invoice. UAE businesses should ensure the following details are clearly stated: 

  • Supplier and customer details: Legal business name, address, and contact information of both parties for identification and reference. 
  • Description of goods or services: Clear description, quantities, and specifications to avoid misunderstandings. 
  • Prices, discounts, and delivery terms: Unit prices, total value, applicable discounts, and agreed delivery or shipping terms. 
  • VAT indication (if applicable): Clear mention of whether VAT applies, including the rate or a note that VAT will be charged on the tax invoice. 
  • Validity period and payment terms: Time period for which the proforma invoice is valid and the agreed payment conditions, including advance payment requirements. 

Best practices for using proforma invoices in the UAE 

To use proforma invoices effectively while staying compliant with UAE VAT regulations, businesses should follow structured and consistent practices. These best practices help reduce errors, improve traceability, and ensure smooth conversion to final tax invoices. 

  • Clear labelling and documentation: Always clearly mark the document as “Proforma Invoice” to avoid confusion with tax invoices or accounting records. 
  • Link proforma invoices to final tax invoices: Maintain a clear reference between the proforma invoice and the corresponding tax invoice issued later. 
  • Maintain audit trails for VAT compliance: Keep proper records of approvals, advance payments, and invoice conversions to support VAT audits. 
  • Use accounting software for accuracy: Automated systems help manage document flow, reduce manual errors, and ensure timely issuance of tax invoices. 

Following these practices ensures transparency, compliance, and smoother sales and trade operations in the UAE. 

Uses of a proforma invoice in UAE business transactions include helping sellers and buyers agree on pricing, terms, and conditions before a sale is finalised. Proforma invoices are commonly used for quotations, advance payment requests, and export transactions, providing clarity at the pre-sale stage and reducing the chances of misunderstandings. 

While proforma invoices do not trigger VAT on their own, they play an important role in supporting VAT compliance, especially when advance payments are involved. Businesses must ensure that proforma invoices are followed by valid tax invoices within the required timelines and that records are maintained accurately for audit purposes. Accounting solutions such as TallyPrime, which allow businesses to create proforma invoices, track transactions, and convert them into VAT-compliant tax invoices, can help manage this process efficiently while maintaining proper documentation.
