What should a sole trader put on an invoice?
A sole trader can invoice under a business or trading name, but the invoice still needs to identify the individual behind that business as well as containing the normal invoice information.

Your own name and your trading name
Along with the standard invoice details, GOV.UK says a sole trader invoice must include your own name and any business name you use.
If you use a business name, the invoice must also include an address where legal documents can be delivered to you.
Build the invoice around a clear customer record
Use the customer's proper name or business name and address. If there is a particular contact person, adding their name can make the invoice easier to route without replacing the customer or business identity itself.
Keep your identity consistent
Once you settle on how your trading name, legal name and address appear, keeping the same structure from invoice to invoice makes your documents easier to recognise and reduces the chance of leaving required details out.
Do not add VAT unless it applies
A normal sole-trader invoice does not become a VAT invoice simply because it is professional-looking. If you are VAT registered, use the additional VAT information described in the VAT guide; if you are not VAT registered, do not present VAT as though you are charging it.
Why Klamic keeps trading and legal names separately
Klamic lets a sole trader present the trading name prominently while retaining the individual's legal name and address in the invoice identity. When an invoice is finalised, those details are frozen with that invoice so later profile changes do not rewrite the historic document.
