Free Invoice Template Generator

Every invoice you send should include enough detail for your client to process it quickly. At a minimum, you need:

• Your business name and address so the client knows who is billing them.
• The client’s name (or company name) for their records.
• A unique invoice reference such as INV-001. Sequential numbering makes bookkeeping easier for both sides.
• A clear description of the work or services provided.
• The total amount owed in GBP.
• The invoice date and due date, so there is no ambiguity about when payment is expected.
• Your payment details (bank account, sort code, or PayPal address).

If you are VAT registered, you must also include your VAT number, the VAT rate, and a breakdown of the VAT charged. Tick the “VAT registered?” option above to add these details to your invoice.

Under the Late Payment of Commercial Debts (Interest) Act 1998, you can charge statutory interest on overdue B2B invoices at 8% above the Bank of England base rate. You can also claim fixed compensation of £40 to £100 per invoice. These rights apply automatically to B2B invoices, whether or not your invoice mentions them, unless your contract already specifies a different late payment interest rate.

So why include a clause? Because most clients do not know this law exists. A short note on your invoice reminds them that late payment has a real cost. In practice, invoices with a late payment clause get paid faster.

Our template adds this clause to the footer of every invoice you generate. You can also use our late payment interest calculator to work out exactly what you are owed on an overdue invoice.
