Free invoice creator UK — what makes a valid invoice?
A UK freelancer invoice template should always include: a unique invoice number, the date issued, your name (and trading name), the client's name and address, a clear description of the work, the amount due, and your payment terms and bank details. If you're VAT-registered, you must also show your VAT registration number, the VAT rate applied, the net amount, the VAT amount, and the gross total.
Self-employed invoice generator UK — best practices
- Number invoices sequentially — HMRC requires unique, sequential numbering.
- State your payment terms clearly (e.g. "Payable within 14 days").
- Include your business address if you trade from one.
- Send promptly — invoices sent within 24 hours of completion get paid faster.
- Keep a digital copy of every invoice for at least 5 years after the 31 January submission deadline.

Do I need to charge VAT?
Only if you're VAT-registered. You must register once your taxable turnover exceeds £90,000 in any rolling 12 months. Many freelancers register voluntarily before that to reclaim VAT on business purchases or to look more established to clients.
