How to Invoice as a Freelancer in the UK: Template

Last reviewed: 3 August 2026.

A UK freelance invoice should clearly identify you and your client, describe the work, show the supply and invoice dates, state each amount and the total due, and give an unambiguous payment deadline. Sole traders should include their own name, any business name used and an address where legal documents can be delivered.

Use the checklist and copyable example below to create an invoice for freelance work. The exact VAT and company requirements differ, so check your status before sending it.

What a UK freelance invoice should include

• A unique, sequential invoice number.
• Your name, business name if used, address and contact details.
• The client’s correct legal or business name and address.
• A clear description of the service or deliverable.
• The date the service was supplied.
• The invoice issue date.
• Itemised fees, quantities or agreed stages where useful.
• VAT amount and VAT details when applicable.
• The total amount owed and currency.
• The payment due date and agreed payment terms.
• Payment instructions, such as account name, sort code and account number, or a secure payment link.

This reflects the core requirements in the official GOV.UK invoicing guidance. A purchase-order number, client reference, project code and late-payment wording can also help when the client requires them.

How to number freelance invoices

Use a unique identification number and a system you can maintain. Examples include 2026-001, 2026-002 and 2026-003, or a client prefix such as ABC-026. Do not reuse a number. If an invoice needs correction, retain a clear audit trail through a corrected invoice or credit note rather than silently overwriting the business record.

Payment terms and due dates

Agree payment terms before starting work and repeat them on the invoice. “Due within 14 days of the invoice date” is clearer when paired with the exact date. GOV.UK says that when no payment date has been agreed, a customer generally must pay within 30 days of receiving the invoice or the goods or service.

For staged projects, connect the invoice to the signed proposal or contract: for example, 50% before work begins and 50% on delivery. Avoid adding unexpected terms after the work is complete.

VAT invoices

If you and the customer are VAT registered, a VAT invoice is required and contains additional information. This can include your VAT registration number, the tax point, net amounts, VAT rates and VAT charged. Do not add VAT merely to make an invoice look formal. Check the current VAT invoice rules or ask a qualified professional where the treatment is unclear.

Invoices for overseas clients

State the currency, payment method and who bears transfer fees. VAT treatment can depend on the customer, location and service, so do not copy the VAT wording from a domestic invoice without checking. Keep the contract, invoice and evidence of the payment received.

Sending and tracking an invoice

1. Confirm the client’s billing name, address, contact and purchase-order requirements.
2. Send the invoice as a locked PDF or through reputable invoicing software.
3. Use a clear subject line containing your name and invoice number.
4. Record the issue date, due date and amount in your bookkeeping system.
5. Confirm receipt when a new client or large payment is involved.
6. Mark the invoice paid only when the money arrives and retain the record.

Accounting software can create consistent invoices and track unpaid balances. Compare the practical options in our accounting-software guide for UK sole traders.

Chasing a late freelance invoice

Start with a calm reminder that includes the invoice number, original due date, outstanding amount and a copy of the invoice. Check whether the client disputes the work or is waiting for a purchase order. Escalate in writing and keep a record of every contact.

Businesses can have rights to statutory interest and fixed recovery costs for qualifying late commercial payments, but the rules and any contract terms matter. Check GOV.UK late-payment guidance before adding a charge or taking recovery action.

Freelance invoice mistakes to avoid

• Using “Invoice 1” repeatedly or omitting an invoice number.
• Sending it to the project contact instead of the billing contact.
• Leaving out the supply date or exact due date.
• Describing the work too vaguely for the client to approve it.
• Using personal bank details without confirming the account permits business use.
• Adding VAT when not entitled to charge it.
• Failing to save a copy and record the payment.

Frequently asked questions

How do I invoice as a freelancer in the UK?

Create a uniquely numbered invoice containing the required supplier, customer, service, date and amount information; add clear payment terms; send it to the correct billing contact; and keep it with your business records.

Can a freelancer invoice without a company?

Yes. A sole trader can invoice under their own name and may also use a business name. The invoice should include the sole trader’s name and, when a business name is used, an address where legal documents can be delivered.

Is an invoice the same as a receipt?

No. An invoice requests payment; a receipt acknowledges that payment was received.
