Freelance Invoice Template UK: Invoice Your First Client

An invoice identifies the work, the parties, the amount owed and when payment is due. Start with the template below, use the terms already agreed with your client, and keep a copy of exactly what you send.

Get the invoice template

Download the editable freelance invoice (.xlsx). It contains a blank invoice and a fictional completed example. No signup is required. Open it in Excel or import it into your spreadsheet app; edit the yellow cells and check the calculated total before exporting the invoice sheet to PDF.

Complete the essential details

GOV.UK requires a unique invoice identifier, supplier and customer details, a clear account of the goods or services, the supply and invoice dates, the charges, VAT where applicable and the total. A sole trader also includes their own name, any trading name and, when using a business name, an address for legal documents. A limited company uses its full incorporated name; naming any directors means naming all of them.

Add the purchase-order reference if the customer requires one, the agreed due date, payment reference and a contact for queries. Check who actually owes the money: a brand name or the person who commissioned the work may not be the legal customer.

Describe what was agreed

Use a description a finance team can match to an approved brief. “Website copy, six agreed hours, project DEMO-WEB-01” is easier to reconcile than “services”. For a fixed fee, use one project or milestone quantity and the agreed fee. A time log can support that invoice, but it does not turn extra hours into an authorised extra charge.

Check quantities against your timesheet. Confirm deposits already received, approved expenses and any credit separately so you do not charge twice. Agree fees and due dates through the contract discussion before invoicing.

Send it and keep a record

1. Confirm the billing name, address, purchase order and accounts contact.
2. Replace every bracketed field and confirm the dates. Check each line and the final amount independently.
3. Export only the completed invoice sheet to PDF. Use print preview and fit the sheet to one page wide so no amount is cut off.
4. Send the PDF with a short subject such as “Invoice INV-2026-001: website copy”. State the amount and agreed due date.
5. Log the sent date, due date, amount, payment and any query. Keep the invoice and supporting agreement in your records.

Verify unexpected requests to change bank details using a trusted contact route. Do not assume an email thread alone proves that a new payment destination is genuine.

When does software help?

A document and a small register can be enough for occasional invoices when you reliably check dates and payments. Consider software when repeated billing, time entries or reminders are consuming time or producing mistakes.

FreshBooks documents invoice creation, billable time and automatic payment reminders. Its UK monthly pricing page checked on 9 September 2026 showed Lite at a standard £16 per month, with an advertised £8 per month for the first three months and a five-client limit. Plus showed a standard £30 per month and a 50-client limit. Verify the billing option, tax treatment, renewal total and any payment-processing fees at checkout; the captured pricing text did not establish whether those displayed prices included VAT.

Use FreshBooks UK plans to check your actual requirements. This is guidance from documentation, not a firsthand product test or a claim about HMRC suitability.
