What information should an invoice include?
Use a practical invoice checklist covering identity, line items, payment terms, references, and totals.
A good invoice answers four questions without forcing the customer to investigate: who is charging, what is being charged, how much is due, and when and how it should be paid.
Identify both parties
Show the legal or trading name and contact details of the seller. Add the customer's correct billing name and address, using the information requested by their finance team.
Registration, tax, or license identifiers may be required for your location or industry. Only include identifiers that are relevant and safe to share on the document.
- Seller name and address
- Customer billing details
- Relevant registration identifiers
- A reliable contact method
Describe the transaction
Use specific line-item descriptions. A label such as June website maintenance is easier to approve than Services. Include service dates, quantities, units, rates, discounts, taxes, and the final total where relevant.
Reference the accepted quote, purchase order, contract, or project so the customer can connect the invoice to prior approval.
Make payment unambiguous
Display the currency, balance due, exact due date, accepted payment method, and reference the customer must use. Check bank or payment details carefully before sending.
Keep the layout readable. Important numbers should not be hidden in dense notes, and advertising should never appear inside the business document itself.
