Getting paid

Invoice vs receipt: the difference and when you need each.

An invoice asks for payment; a receipt confirms it. Same parties, often the same line items — but they live on opposite sides of the transaction, and mixing them up confuses clients, accountants, and tax season.

In short

An invoice is a request for payment issued before the client pays: it lists what was delivered, what it costs, and how to pay. A receipt is proof of payment issued after: it confirms what was paid, when, and how. You send the invoice when work is delivered and the receipt when money arrives. Invoicing software issues both from the same record, keeping the numbers, line items, and client reference identical on each.

The difference in one table

Same transaction, opposite sides of it:

  • Invoice — issued before payment; a formal request listing items, rates, totals, terms, and how to pay
  • Receipt — issued after payment; confirmation showing amount paid, date, method, and the invoice it settles
  • Invoice answers "what do I owe you?" — receipt answers "what did I pay, and when?"
  • Both belong in the client record: the invoice as the ask, the receipt as the proof

What each document must include

They share most fields, with different emphasis:

  • Invoice — your details, client details, invoice number, issue and due dates, line items, taxes, total, payment instructions
  • Receipt — your details, client details, the invoice number it settles, payment date, amount received, payment method, and any remaining balance
  • Both — the same line items and totals so the paper trail reconciles exactly

Keep them connected

The receipt should reference the invoice it settles — that is what lets a client (or their accountant) match the payment to the ask without an email thread. In Workspace369, receipts are issued from the paid invoice, so the reference, line items, and amounts always match.

FAQ

Common questions

Is an invoice a receipt?

No. An invoice requests payment before it happens; a receipt confirms payment after. They carry similar information but serve opposite purposes in the transaction.

When do I send a receipt?

After the client pays. For card payments online, send it automatically on payment confirmation. For bank transfers or checks, issue it once the money clears.

What should a payment receipt include?

Your business name and contact details, the client, a receipt number, the invoice number it settles, the payment date, the amount received, the payment method, and any balance still due. If you charge tax, show the tax included in the payment.

Can I turn an invoice into a receipt?

Yes, as long as the receipt is clearly marked as a receipt (or the invoice is marked "Paid") and shows the payment date, amount and method. Keep the original invoice unchanged; the receipt is a separate record of the payment.

Do I need both for taxes?

You need the invoice to show what you billed and the receipt or payment record to show what you collected. Together they reconcile your books; missing receipts are what make tax season a reconstruction project.
