Requirements vary by country, but most invoices that pass muster with accountants, tax authorities, and clients share the same core fields. Missing one is the most common reason an invoice bounces back with "can you resend with X?"
The essentials
- A clear label. The word "Invoice" at the top, not just a logo and a number.
- A unique invoice number. Sequential and never reused — see our invoice numbering guide for a format that scales.
- The invoice date. When the invoice was issued.
- The due date, or clearly stated payment terms (e.g. "Net 30"). See setting payment terms.
- Your business details. Legal or trading name, address, and a tax/VAT ID if you have one.
- The client's details. Name and billing address, so it's clear who owes what.
- An itemized description of what's being billed — each line with a quantity, a unit price, and a line total, not just a single lump sum.
- Subtotal, tax, and total. Shown separately, not merged into one number the client has to reverse-engineer.
- Payment instructions. How you want to be paid — bank details, a payment link, or whatever method you accept.
Worth adding, even when not strictly required
- Currency, explicitly, if you or the client operate internationally.
- A note or memo field for anything the client needs context on — a purchase order number they asked you to reference, or a thank-you line.
- Late payment terms, stated up front (a late fee percentage, for instance) rather than introduced after the fact. Our late payment fee calculator helps you decide on a reasonable figure.
What you can usually leave off
You don't need your bank's routing details splashed across the invoice if you're being paid via a payment link instead — only include the payment method you actually want used, so there's no ambiguity about how to pay. And you don't need a wall of legal terms; a short, clear note beats three paragraphs of boilerplate nobody reads.
A complete invoice isn't about looking more official — it's about removing every reason the client might have to come back with a question before they pay.
