VAT basics

Proforma invoices (proformas) are preliminary documents usually sent to buyers in advance of a delivery of goods/provision of services. Proformas will typically describe details of the purchase of goods/services and other important information, such as the terms of the transaction. Proformas are not “official” documents and represent an informal agreement. Usually, requesting a proforma represents a more serious interest on the part of a buyer than a quote – a buyer is generally committed to making a purchase but want to understand the details before proceeding with the approval process and making a binding agreement with the seller. They are therefore a useful business tool and use of them may result in a beneficial cashflow position for VAT (please see below).

Proforma translates from Latin as “for the sake of form”, and this provides an indication that the document is provisional or a step in a process.

It is also worth noting that the use of proformas is not mandatory.

The difference between an invoice and a proforma

Invoices (also called commercial invoices, VAT invoices or tax invoices) are distinct from proformas. They may contain similar information but serve different purposes. It is important to avoid confusing the two, since only invoices are legal documents; that is, they evidence a transaction and is the document on which VAT may be claimed. An invoice must contain certain information and there are specific legal obligations for providing them.

It is a matter of law whether an invoice is valid and when they must be issued. A proforma is not required to follow any set form, apart from the facts that they must not have an invoice number and must state that it is a proforma invoice. We also recommend that a proforma does not show the supplier’s VAT number for the avoidance of doubt.

Contents of a proforma

Proformas can be considered as “dummy invoices” and they are prepared by the seller usually to provide details of:

• the issuing business’s name, address, and contact details
• customer’s name and address
• date of issue
• length of time the pricing is valid
• the goods/services requested, including quantities, type, and physical specifications
• pricing, including individual costs as well as the total amount to be charged
• terms of sale, including eg; shipping and delivery dates
• payment terms
• whether VAT is applicable

However, there are no set formats for proformas.

Use for buyer

The purpose of a proforma is to provide the buyer with an accurate and complete good faith estimate they can use to decide whether or not to go ahead with a transaction. It also avoids surprises when the actual tax invoice is issued.

VAT implications

The main distinctions are that, compared to a tax invoice, a proforma:

• does not create a tax point
• the recipient is unable to recover input tax on a proforma

Very broadly, the tax point (time of supply) this is the earliest of; invoice date, receipt of payment, goods transferred or services completed. The tax point fact is helpful in tax planning for suppliers. Broadly, using proformas, requests for payment, or similar documents rather than issuing an invoice, defers a tax point and consequently when VAT is payable to HMRC. This is especially relevant to businesses which provide ongoing services (known as continuous supplies of services).
