United Kingdom Invoice Generator

What is an invoice in United Kingdom?

An invoice is an official request for payment that records what you sold, who you sold it to, and on what terms. For businesses in United Kingdom, invoices act as the core document for bookkeeping, vat reporting and proof-of-sale. They help both you and your customer keep track of work completed, payment deadlines and any vat that has been charged.

A professional invoice should be clear, consistent and easy to read. When you use this online invoice generator, all of your key information is structured in a standard format that looks good to clients and makes your accountant’s life much easier.

Required fields on a United Kingdom invoice

Exact legal requirements can change, so always check guidance from your local HMRC or a qualified accountant. As a practical checklist, most businesses in United Kingdom will want their invoices to include:

• Your business name, address and contact details
• The customer’s name and billing address
• A unique invoice number for your records
• The invoice date and, if different, the service or supply date
• A clear description of each product or service, including quantity and unit price
• Subtotals before tax, any discounts and the total amount of vat charged
• The final total amount due from the customer
• Your VAT registration number (if you are registered for tax)
• Your company registration number (if applicable)
• The VAT rate applied to each item (for VAT-registered businesses)
• Clear payment terms and accepted payment methods

How to create an invoice in United Kingdom (step by step)

1. Add your business details. Enter your trading name, address, email and phone number so the client knows exactly who is billing them.
2. Enter your client’s details. Add the customer’s legal name and billing address, along with an email address for sending the invoice.
3. Set invoice number and dates. Use a clear numbering system (for example INV-0001, INV-0002) and choose the invoice date and due date according to your payment terms.
4. List your products or services. For each line item, describe the work, choose a quantity (hours, units, days) and set the rate or unit price. The invoice generator will calculate line totals for you.
5. Apply discounts and VAT. If you offer a percentage discount, add it once and the tool adjusts your subtotal. Then add your vat rate so all tax amounts are calculated automatically.
6. Review payment info and notes. Use the notes and payment information areas to add bank details, late-payment policies or a thank-you message to your customer.
