What to put on an invoice

An invoice is a simple promise: here’s what I did, here’s what you owe, and here’s how to pay me. The faster a client can read it and act, the faster you’re paid. A complete US invoice carries a handful of standard parts.

• Your details — your name or business, mailing address and email, so the client knows who to pay and where to ask questions.
• Client details — the company or person being billed, with their contact information.
• An invoice number — a unique reference (for example INV-001) that you never reuse, so both sides can track it.
• Dates — the issue date and a due date, never left vague.
• Line items — each task or product on its own row, with quantity and rate, so the total is easy to follow.
• Subtotal, tax and total — show any sales tax as its own line rather than folding it into your rates, then a clear total due.
• Payment terms and methods — when payment is due and how to send it, whether that’s a bank transfer, check or a payment link.

Getting paid faster

Most late payments come down to friction, not bad faith. Remove the friction and money arrives sooner. Send the invoice the day the work is done — invoices age badly — and give a specific due date rather than “soon.” Net-15 and net-30 are the common US terms (payment due 15 or 30 days after the issue date); shorter terms mean faster cash, so use net-15 unless you’ve agreed otherwise. If you charge a late fee, state it on the invoice up front, such as a small percentage per month past due. Keep invoice numbers sequential so nothing slips through the cracks, use plain descriptions a non-expert can understand, and offer at least one easy way to pay.
