UK Invoice Generator

A working browser tool — not a template. Type your details, add line items, and watch net, VAT and gross totals recalculate in real time. Export the finished invoice as a PDF when you're done. For a static reference layout instead, see the UK Invoice Template.

Privacy note: your invoice data stays in your browser. PoundKit does not send invoice details to a server in this MVP.

Invoice workflow — quote to paid, in 5 steps

  1. Agree the price. Send a quote or quotation first. Get written acceptance before you start work.
  2. Set your rate. Use the Freelance Rate Calculator or Profit Margin Calculator to sanity-check your pricing before invoicing.
  3. Calculate VAT. If you're VAT-registered, use the UK VAT Calculator to confirm the net, VAT and gross totals per line.
  4. Generate the invoice. Fill in the form above — totals recalculate live. Save as a PDF.
  5. Send & chase. Email the PDF the same day, note the due date, and follow up politely if it isn't paid on time.

Need to send a quote first?

Sending a price before work is agreed? Use these first, then come back here to create your invoice once the quote is accepted:

What to include on a UK invoice

  • A unique, sequential invoice number
  • Your business name (and trading name if different) and address
  • The client's name and address
  • The invoice date and the date of supply (tax point)
  • A clear description of the goods or services supplied
  • The amount being charged (and VAT, if registered)
  • Your VAT number if you are VAT-registered
  • Payment terms and how to pay

Sole trader vs limited company

Sole traders invoice in their own name (and trading name if different). No company number is required.

Limited companies must use the full registered company name and include the company number.

How invoice numbers work

Invoice numbers must be unique and sequential. A simple format like INV-2026-0001 works well — this generator suggests the next number automatically.

Questions

  • Is this invoice generator free?

    Yes — entirely free with no sign-up. You can generate as many invoices as you like.

  • Is my invoice data stored?

    Invoice data only stays in your browser via localStorage when you choose to save a draft. Nothing is sent to a server in this MVP.

  • Can I create a VAT invoice?

    Yes. Toggle 'VAT registered' on, enter your VAT number, and set the VAT rate per line. The preview and PDF will show the VAT columns and totals.

  • Can a sole trader use this invoice generator?

    Yes. Include your own name (and trading name if different) plus your full address. Sole traders don't need a company number.

  • Can a limited company use this invoice generator?

    Yes. Add your registered company name and company number, and your VAT number if registered.

  • Does this replace accounting software?

    No — it's a quick tool for generating individual invoices. For ongoing bookkeeping use proper accounting software.

  • Can I use the PDF for my records?

    Yes. Save each invoice as a PDF and keep a copy with your business records.
