Free invoice template for UK sole traders

Guide · Last checked: 21 October 2026

An invoice tells your customer what they owe and when. GOV.UK sets out what it must include. Get these right and you'll look professional and get paid faster.

What your invoice must include

a unique identification number (for example INV-1001, then INV-1002)
your name, address and contact details
your customer's name (or company name) and address
a clear description of what you're charging for
the date you provided the goods or service (the supply date)
the date of the invoice
the amount for each item, and VAT if it applies
the total amount owed

Extra rules for sole traders

Include your own name, as well as any business name you trade under.
If you use a business name, include an address where legal documents can be delivered to you.

Do I need to charge VAT?

Only if you're VAT registered. If you and your customer are both VAT registered, you must use a VAT invoice, which needs more details. Check the GOV.UK guidance on VAT invoices if this applies to you.

Good habits that help you get paid

Put your payment terms on the invoice, for example "Payment due within 14 days".
Add your bank details so it's easy to pay you.
Keep a copy of every invoice for your records and your tax return.
