UK invoice template for getting paid properly.

Invoice identity

• The word "Invoice" clearly shown.
• A unique invoice number that you do not reuse.
• Invoice date and, where useful, the date the work was completed.
• Payment due date or payment terms, such as 7 days or 14 days.

Parties and payment

• Your business or trading name and address.
• Your customer's name and billing address.
• Your email or phone number for invoice queries.
• Bank details, payment link, or payment instructions.

Work and amounts

• Clear line-item descriptions, not just "work".
• Quantity, day rate, hourly rate, fixed fee, or unit price.
• Materials, expenses, discounts, and deposits where relevant.
• Subtotal, VAT if applicable, and total amount due.

Tax and business details

• VAT number and VAT rate if you are VAT-registered.
• Company registration number if you trade through a limited company.
• UTR or CIS details only where relevant to the customer or trade.
• Any reverse charge wording where construction VAT reverse charge applies.

Common mistakes

• Reusing invoice numbers or leaving invoice numbers blank.
• Leaving out the due date, which makes chasing awkward.
• Using vague descriptions that customers dispute later.
• Adding VAT when you are not VAT-registered.
• Forgetting bank details or using the wrong payment reference.

When to send it

Send the invoice as soon as the job is finished, the milestone is reached, or the agreed billing period ends. Faster invoicing usually means faster payment, especially for domestic jobs, property work, and small commercial projects.
