A UK invoice is a formal commercial document issued by a business or freelancer to request payment for goods or services provided to a customer.

  • what goods or services were provided
  • when the transaction occurred
  • how much money is owed
  • payment deadlines
  • tax information where applicable

Businesses and freelancers use invoices for:

  • payment tracking
  • bookkeeping
  • legal documentation
  • HMRC tax records
  • proof of income

What should be included on a UK invoice?

Invoices also help reduce payment disputes because they clearly show the exact products or services that were supplied to the customer.

For VAT-registered businesses in the UK, invoices may also be legally required for tax reporting purposes.

UK invoices must contain certain information, especially when VAT is involved or when invoices are being used for accounting and HMRC purposes.

A professional UK invoice should include:

  • The word “Invoice” clearly visible
  • A unique invoice number (e.g. 001, 002, 003)
  • Seller details including company name, address, and contact information
  • Customer details including customer name, business name, and billing address
  • Invoice issue date
  • Payment due date
  • Description of goods or services provided
  • Quantity and pricing information
  • VAT information if applicable
  • Final balance due

Details section

These examples shown are made using invoiceatlas.com to create a free invoice for the UK. When creating an invoice you always want to start with the details section of the invoice, this includes the text stating clearly that it's an invoice (as shown in figure 1) that you can also add a logo to an invoice for extra branding when sending an email to clients. You should also include a unique invoice number such as 001, 002, or another sequential numbering format to help identify each invoice. A purchase order must also be included to help link the buyer to that specific purchase and can also help prove that a purchase was approved, and can act as a legally binding document that can protect both parties.

Invoices should also include an invoice date as well as a due date for the invoice. Then finally you can write the payment terms for the goods/services provided and for what time period payment must be made within e.g. 7 days or 30 days..

From and Bill To section

The next section is a requirement for invoices and these are (as shown in figure 2) the “From” and “Bill To” section of an invoice, the “From” section is where you enter information like your company name, email, address and phone number. The “From” section is necessary and helps provide contact information to the client so they have an available method to contact you if they have any queries and also helps identify you as the party legally demanding the money.Then the “Bill To” section includes the client’s name, email, address and phone number. This helps to identify the debtor and binds them to what money is owed, it’s also needed for proving a commercial agreement was made and is used by HMRC to verify who received the goods/services.
