Free Word invoice template (UK)

What's included in the Word template

• A fully editable .docx file with a clean A4 layout
• Your business name, address, email and optional VAT number
• Customer name and billing address
• Unique invoice number, invoice date and time of supply
• Line items with description, quantity, unit price, VAT rate and amount
• Subtotal, VAT breakdown and total including VAT
• Payment terms, due date and optional notes

• UK VAT invoice template (Word .docx)
• Same layout as a PDF example

How to fill in the Word invoice

1. Open the .docx in Word, Google Docs or LibreOffice and save a copy with your business name.
2. Replace the sample business details, including your address and VAT number if you are VAT registered.
3. Enter a unique invoice number, the invoice date and the time of supply (the date the work was done or the goods were provided).
4. Add each line item: what you supplied, quantity, unit price and the correct VAT rate (20%, 5% or 0%).
5. Check the subtotal, VAT and total. If you are not VAT registered, remove the VAT number and VAT lines.
6. Add payment terms and a due date, then export to PDF before sending so the layout cannot change.

Word template vs online invoice generator

A Word template is useful when you want full control over branding, or when you need to work offline. The downside is that totals, VAT and line breaks are manual: one wrong cell or a long description can push the table onto a second page.

An online generator is faster for repeat invoices and calculates the totals for you. Use the Word file when you need a specific layout, and use the browser generator when speed and accuracy matter. Both produce a PDF you can send to a client.

UK invoice fields to keep

• A unique, sequential invoice number
• The invoice date and the time of supply
• Your business name, address and VAT registration number (if registered)
• The customer's name and address
• A clear description of the goods or services
• The quantity, unit price and amount before VAT
• The VAT rate and VAT amount for each line
• The total before VAT, the total VAT and the total including VAT
• Any cash discount terms

If you are not VAT registered, do not charge VAT or show a VAT number. Keep your invoice numbering consistent and retain copies for your records.

Common Word invoice mistakes

• Sending the editable .docx instead of a PDF — the layout can change on the client's device
• Reusing or skipping invoice numbers
• Forgetting the time of supply on longer projects
• Typing totals by hand and creating rounding errors
• Leaving the sample business name or address in the file
• Missing payment terms, so the customer does not know when payment is due
