Tips for UK freelancers
- Sequential numbering. HMRC requires invoice numbers to be unique and sequential. Try formats like
2026-001,2026-002. - VAT registered? Use the VAT Invoice template for a fully HMRC-compliant document with VAT breakdown.
- Not VAT registered. Pick "No VAT" as the default rate — VAT columns are hidden in the preview.
- Late-payment terms. Under the Late Payment of Commercial Debts Act, statutory interest is 8% above the Bank of England base rate plus a fixed compensation tier (£40/£70/£100). When an invoice goes overdue, run it through our late payment interest calculator for the exact figures plus pre-filled demand-letter wording.
- Chasing a late invoice? Use our five-stage reminder email templates — copy-paste, fillable, calm tone. See the full escalation ladder in how to chase unpaid invoices in the UK.
- Invoicing overseas clients? See our foreign currency invoice guide, the international payments playbook, and the best way to get paid by overseas clients.
- Planning to buy a property? The income figure shown on your SA302 (sole trader) or salary+dividends (Ltd) is what UK lenders assess. See our freelancer mortgage guide and the borrowing calculator.
- Tracking expenses cleanly? See what expenses freelancers can claim and the bookkeeping playbook.
- Deciding sole trader vs Ltd? Run the sole trader vs Ltd calculator or read the definitive guide.
