Subcontractor Invoice Template and Generator

A UK invoice normally needs a unique invoice number, your business name and address, the customer's details, the date of issue, a description of what was supplied, the amount due and the payment terms. If you are VAT registered you also need your VAT number, the rate applied and the VAT amount. Public sector customers usually add a requirement of their own: quote the purchase order number, or the invoice goes to the back of the queue.

1. Enter your business name, address and any registration numbers you need to show.
2. Add the customer details, an invoice number and the invoice and due dates.
3. Add one line per item of work, with a clear description, quantity and unit price.
4. Set the VAT rate and the payment terms, check the preview, then print or save as PDF.

A cleaning contractor invoices a school for a September deep clean and two weeks of routine cover.

• Line 1: deep clean, 1 x 1,200 = 1,200.
• Line 2: routine cover, 10 days x 145 = 1,450.
• Subtotal: 2,650. VAT at 20%: 530.

Total payable 3,180, with 30-day terms and a purchase order number quoted on the invoice so the school's finance team can match it against the contract.

Late payment in the UK is often an invoicing problem rather than a cash problem. Missing purchase order references, vague descriptions and unclear due dates all give a finance team a reason to park an invoice. A clear, consistent invoice with proper terms is the cheapest way to get paid on time, and it gives you firm ground if you later need to claim statutory interest.

Is the invoice generator really free?

Yes. There is no sign-up, no watermark and no limit on how many invoices you create.

Where is my data stored?

In your browser only, for as long as the page is open. Nothing is sent to a server, so save or print the finished invoice before you close the tab.

Can I save the invoice as a PDF?

Yes. Use your browser's print dialog and choose Save as PDF. The page has a dedicated print layout so only the invoice is output.

What must a UK invoice include?

A unique number, your details and the customer's, the date, a description of the supply, the amount due and the payment terms, plus your VAT number and VAT breakdown if you are registered.

How should a subcontractor invoice show labour and materials?

Put them on separate lines. Under the Construction Industry Scheme the contractor deducts tax from the labour only, so a single combined figure invites a deduction on your materials as well.
