What is the difference between an invoice and a receipt?

An invoice is a request for payment: it states what is owed, to whom, and when it is due. A receipt is proof that payment already happened. If the money has not moved yet, you want an invoice. Once it has, you want a receipt or a bank record that plays the same role. That is the whole distinction.

When do you use an invoice vs a receipt?

Use an invoice when you are asking to be paid: after you finish work or close out a billable period. Use a receipt after the money arrives, to confirm it. Service businesses almost always invoice first and may send a receipt later. Retail flips the order, handing 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 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 might invoice a deposit before the shoot and a balance after delivery; each invoice is its own request. A videographer might invoice half at rough cut and half at master delivery so cash flow follows the edit. A 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.

What should you do if a client confuses the two?

Name the document plainly and move on. Tell them: this is the invoice for the work we finished Tuesday, and payment is due on the fifteenth. If someone asks for a receipt before paying, they usually mean a quote or a contract instead. Fix the vocabulary once and you spare yourself a string of 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.
