Small Business Invoice UK 2026 — Professional PDF Within Seconds

UK small business invoice requirements

HMRC expects every sale or service to be documented with an invoice or receipt as part of your business records. The exact requirements depend on whether your business is VAT registered.

Annual turnover	VAT required?	Invoice type
Under £90,000	No	Standard invoice — no VAT
Over £90,000	Yes — must register	VAT Invoice — 20% VAT
Voluntary registration	Optional below £90k	VAT Invoice — 20% VAT

💡

Register within 30 days of going over £90k. HMRC can backdate VAT obligations if you register late. If you're approaching the threshold, register proactively to avoid penalties.

Small business invoicing UK — FAQ

What must a UK small business include on an invoice?

Your business or full name and contact details, an invoice number, the invoice date, a description of goods or services, the total amount, and your payment details. If you're VAT registered, add your VAT number, the words "VAT Invoice", and show the VAT amount separately from the subtotal.

Do UK small businesses need to charge VAT?

Only if your taxable turnover exceeds £90,000 in any rolling 12-month period. Below that threshold you are not required to register for VAT and should not charge it or show a VAT number. Once you exceed £90,000 you must register with HMRC within 30 days.

Do UK small businesses need accounting software to invoice?

No. There is no legal requirement to use accounting software. You can create invoices using any method as long as they contain the required information and you keep records for at least 5 years after the relevant Self Assessment deadline. TradieNotes creates a professional PDF invoice within seconds for £1 — no subscription needed.

How long must small businesses keep invoices in the UK?

HMRC requires self-employed people and small businesses to keep financial records including invoices for at least 5 years after the 31 January submission deadline for the relevant tax year. Digital records are acceptable — PDFs in cloud storage or email count.

What is the difference between a quote and an invoice?

A quote is sent before work begins and sets out the expected price — it is not a demand for payment. An invoice is sent after work is completed and is a formal request for payment. Quotes are typically valid for 30 days. TradieNotes creates both for £1 each.

Can a UK small business invoice without registering a company?

Yes. Sole traders can invoice using their own name without registering with Companies House. Include your full name, contact details, and VAT number if registered. You only need to register a limited company if required for liability or other business reasons.
