An invoice is the bill that turns work into revenue.

An invoice is a dated document you send to a client that lists what you delivered, how much it cost, and when payment is due. It is the legal record both parties use for accounting, taxes, and dispute resolution.

What every invoice should include

• Your business name, address, and contact so the client knows who to pay and how to reach you.
• The client's name and address as they appear in your contract or order.
• A unique invoice number for your records and theirs. Sequential or date-based (e.g. INV-2026-0042).
• Issue date and due date. Net 14, net 30, or whatever terms you agreed on.
• Itemized line items with description, quantity, rate, and amount. Specific enough that a future you, or an auditor, can reconstruct the work.
• Subtotal, tax (if applicable), and total in one currency. Spell out the currency code if the client is in a different country.
• Payment instructions or notes — wire details, ACH info, or a link to a Stripe / Paddle / Wise payment page.

When to send the invoice

For one-off projects, send the invoice the day the work is delivered. For retainers and subscriptions, send on a predictable cadence (1st of the month works for most clients). The faster you invoice, the faster you get paid — late invoicing is the single most common reason small businesses run out of cash.
