Invoice vs receipt
An invoice is a request for payment: it says what you owe, to whom, and when it is due. A receipt is proof that payment already happened. If money has not left their account yet, you want an invoice. If it has, you want a receipt (or a bank record that plays the same role). That is the whole distinction. Everything else is detail.
| Invoice | Receipt |
|---|---|
| Says money is owed | Says money was received |
| Lists due date and pay instructions | Lists date paid and often the method |
| You send before or when billing | You or their system sends after payment |
| Drives accounts payable to release funds | Closes the loop for bookkeeping |
When each one shows up in real life
Service businesses almost always invoice first. Retail usually hands you a receipt at the till because you pay on the spot. Freelancers sit in the middle: you finish the milestone, you invoice, they pay days or weeks later, then their system might email a receipt automatically. If you shoot a wedding you still invoice for the package balance even if they paid a deposit months ago; the receipt for the deposit does not replace the invoice for what is left.
In a company with a finance team, the invoice is what lets them create a vendor payment. The receipt is what lets them close the file after the bank feed matches. Same money, two checkpoints. If you only ever see the receipt side as a buyer, it is easy to forget that someone had to raise an invoice before anyone typed your IBAN.
Picture a [plumber](/invoice/plumber) named Harborline Plumbing. They replace a burst cylinder at a row house, parts and labor tallied on a job sheet. Before they drive away, they email a PDF invoice for $486.20 due in fourteen days with a sort code and account number. The homeowner pays online. Harborline's bank shows the transfer; their accounting tool marks the invoice paid and can email a short receipt to match. Same job, two moments: ask, then prove.
Creative work follows the same rhythm at a different scale. A [photographer](/invoice/photographer) might invoice a deposit before the shoot and a balance after delivery; each invoice is its own request. A [videographer](/invoice/videographer) might invoice half at rough cut and half at master delivery so cash flow follows the edit. A [bookkeeper](/invoice/bookkeeper) might invoice monthly for ongoing work and send or generate receipts as clients clear each bill. The words matter less than the order: request, then money, then proof.
If a client mixes the words up
Say it plainly. "This is the invoice for the work we finished Tuesday; payment is due the fifteenth." If they ask for a receipt before paying, they mean something else, usually a quote or a contract. Fix the vocabulary once and you save ten confused emails. When you are ready to bill, build the PDF on Invoice No., send it, then move on. Receipts can follow once the money lands.
Mixed-up words do not change the law of gravity: someone has to ask, someone has to pay, someone has to prove it. Invoices and receipts are just the paperwork for those three steps.
