Sole Trader Invoice Guide UK
Everything a UK sole trader needs to invoice clients correctly — legal requirements, the fields HMRC expects, and a clean example layout you can copy.
Legal requirements for sole trader invoices
As a sole trader you don't need a Companies House number, but your invoice must still meet HMRC's record-keeping standards. The basics:
- Use your real legal name — and any trading name, if you use one
- Include a unique, sequential invoice number
- Show your address where customers can contact you
- Keep a copy of every invoice for at least 6 years (Self Assessment record-keeping rules)
Required fields checklist
- Your name (and trading name, if used)
- Your address
- Client name and address
- Unique invoice number (e.g. INV-2026-0001)
- Invoice date and due date
- Description of goods or services
- Total amount due in GBP
- Payment terms and bank details
VAT vs non-VAT
Non-VAT (most sole traders)
Don't show a VAT number, don't add VAT, and just charge the net amount. The total on the invoice is what the client pays.
VAT-registered sole traders
You must also include:
- Your VAT registration number
- The VAT rate applied (20%, 5% or 0%)
- A clear net / VAT / gross breakdown
Not sure if VAT applies to you? Use the VAT Calculator to add or remove VAT on any amount.

Frequently asked questions
Do sole traders need to register before sending invoices?
No. You can start invoicing as soon as you start trading. You must register for Self Assessment with HMRC by 5 October following the end of your first tax year as a sole trader.Do I need a company number on a sole trader invoice?
No. Company numbers only apply to limited companies. Sole traders should use their own legal name and any trading name.Should sole traders charge VAT?
Only if you are VAT registered. Most sole traders are not. You must register once your taxable turnover exceeds the VAT threshold (check GOV.UK for the current figure) or if you choose to register voluntarily.What payment terms should a sole trader set?
14 to 30 days is standard. Shorter terms (7 days) help cash flow but can feel aggressive. Always include your bank details so clients can pay quickly.Can I invoice in my own name as a sole trader?
Yes. Sole traders can invoice using their personal name. If you also use a trading name, include both — for example 'Alex Morgan trading as Morgan Studio'.
