Questions and answers
Short answers in simple English.
Does every UK invoice need VAT details?
No. VAT details apply when the supplier is VAT registered and the transaction requires them.
Can a sole trader use a trading name?
A sole trader may show a trading name, but should also include the required legal identity details.
Should invoice numbers be unique?
Yes. Use a clear sequence so each invoice can be identified.
Can LingvaBill decide whether CIS or VAT applies?
No. The software provides fields and calculations. The business chooses the treatment.
