Online Invoice Generator UK Free (VAT)

What to include on a UK invoice

A clear UK invoice usually shows your trading or company name, address, a unique invoice number, invoice date, and the client's name and address. Describe each line of work or goods with quantity, unit price, and line total so the client can reconcile payment without chasing you.

If you are VAT-registered, show your VAT number and break out VAT rates and amounts on taxable supplies (standard rate is commonly 20%). Construction subcontractors often need CIS-friendly wording and deduction notes — start from the CIS featured generator, then confirm current HMRC rules for your contract. Non-VAT traders can use a no-VAT layout and still keep professional numbering and payment terms.

GBP payment details UK clients expect

Most UK clients pay by Faster Payments or BACS using a UK sort code and account number. Put those under bank details (or Notes) with your invoice number as the payment reference so bookkeepers can match remittances. Limited companies often quote company number and registered office; sole traders use their trading name consistently across From and bank details.

Optional PayPal or card-link lines help overseas clients, but domestic B2B still prefers GBP bank transfer. State due dates in clear UK date style (e.g. 31 March 2026) and Net 14 / Net 30 terms so late-payment chasing starts from a shared baseline.

Sole traders, limited companies, and CIS trades

Sole traders often need a simple GBP PDF with personal trading name, address, and optional VAT. Limited companies usually show the company name, registered office, and company number alongside VAT when registered. Open the matching featured layout so labels match how you trade, then edit line items in the browser.

Construction and building trades commonly bill under CIS. Use the CIS starting point for subcontractor invoices, keep labour and materials readable, and verify deduction statements with HMRC guidance — this generator drafts the client PDF; it does not calculate CIS for you.

From UK estimate or quote to invoice

Many UK freelancers and agencies send an estimate or quote first, agree scope, then invoice on completion or milestones. Create the proposal under UK Estimates or Quotes (same GBP defaults), then convert or copy the agreed lines into an invoice when work starts or finishes.

Keep numbering series separate (EST / QUO / INV) so accountants can tell proposals from tax invoices. If VAT applies only once you invoice, leave tax off the quote and add VAT on the final bill.

UK compliance note

This tool creates editable invoice PDFs for client billing and your own records. It is not HMRC software, not an MTD filing product, and not legal or tax advice. Always check current GOV.UK / HMRC guidance (or your accountant) for VAT, CIS, and record-keeping rules that apply to you.
