What to put on an invoice
- Your business name and contact details (and tax ID if your country requires it).
- The client’s name and address.
- A unique invoice number and the invoice date.
- Each item or service, quantity, rate and line total.
- Tax, discounts and the total due.
- Payment terms — for example “Net 14” — and how to pay.
Invoice numbering tips
Use a simple sequence like INV-001, INV-002 or include the year (2026-014). Never reuse a number. Keep a copy of every invoice for your taxes.
