What should a sole trader put on an invoice?
A UK sole trader can invoice under a business or trading name, but the invoice still needs to identify the individual behind that business. The key is to show both identities clearly and then include the normal UK invoice information.

Sole trader invoice requirements
Along with the standard invoice details, GOV.UK says a sole trader invoice must include:
- your own name
- any business name you are using
- an address where legal documents can be delivered to you if you use a business name
You still need the normal invoice information too, such as a unique invoice number, customer name and address, description of the work, supply date, invoice date, amounts charged and total owed.
For the full checklist, see what a UK invoice should include.
How to write “trading as” on an invoice
To write “trading as” on an invoice, show your own legal name and your trading name together so both are clear. GOV.UK requires your own name and any business name you use, but it does not prescribe one exact visual format.
For example, if Jamie Smith trades as North Street Design, the invoice could show:
Jamie Smith, trading as North Street Design
Business address
Another clear format is:
Jamie Smith — Sole Trader
Business address
You may also see the abbreviation “T/A”, for example “Jamie Smith T/A North Street Design”. The abbreviation is not the important part; making both the legal name and trading name visible is.
Should the trading name or your own name be more prominent?
Your trading name can be the main visual identity if that is how customers know you. You can place your own legal name underneath or nearby in smaller text, provided it remains clear and readable.
This gives the invoice a professional business identity without hiding the individual the customer is actually dealing with.
Use the same format every time
Once you settle on a layout, keep your trading name, legal name and address in the same place on every invoice. Consistency makes invoices easier to recognise and reduces the chance of leaving required details out.
See our UK invoice example for a simple layout showing a trading name alongside the proprietor's own name.
What else should a sole trader invoice include?
Use the customer's proper name or business name and address. Add a clear description of the goods or services, invoice and supply dates, the amounts charged and the total due.
Payment terms
A clear due date and payment instructions reduce uncertainty. If you use bank transfer, include the payment details the customer needs. See our invoice payment terms guide and bank details guide.
VAT
Do not present an invoice as a VAT invoice unless you are VAT registered. VAT invoices have additional requirements; see our VAT invoice guide.
