Proof of payment, done right — and the mistakes that cause disputes.
A receipt is a small document with a big job: months later, it has to prove — to you, to your client, and to anyone checking your books — that a specific payment happened. A receipt that can't answer "who paid, for what, and how much" isn't a receipt at all; it's a scrap of paper. Here are the seven things every receipt needs, why each one matters, and the mistakes that make receipts useless.
Your business name and a way to reach you — email or phone at minimum. This is the part clients need most: when they claim the expense in their own books, the receipt has to show clearly who they paid. A receipt with no business name on it is nearly impossible for a client to file, and it looks unprofessional if a dispute ever arises. If you have a logo, add it — it makes the receipt instantly recognisable as yours.
Give every receipt its own sequential number — RCP-0001, RCP-0002, and so on — and never reuse one. Numbers are how you find a payment again six months later, when a client asks "did I pay that one?" or your accountant asks for a specific transaction. Random or missing numbers turn a simple lookup into a hunt through bank statements. Let the numbering run in order and don't restart it each month.
This is the single most common receipt mistake: writing the date you sent the invoice instead of the date the payment landed. The receipt records a payment, so its date is the payment date. Getting this wrong shifts income into the wrong month in your books and confuses any tax record. If a client pays in instalments, each payment gets its own receipt with its own date.
The payer's name, and their address or email whenever you have it. Your client's name is what lets them match the receipt to their purchase — and it's what proves, in a dispute, that this particular person paid this particular bill. If you only have a name, use the name; a missing address doesn't ruin a receipt, but a missing payer does.
List what was bought or done, line by line, with quantities and prices. "Services — $500" is the line that starts arguments; "Logo design — 1 × $300, business card design — 1 × $200" ends them. Specific lines protect both sides: the client can see what they paid for, and you can prove what you delivered. If the payment covers part of a larger job, say so on the receipt — "Deposit for website redesign, 50% of $1,200" — rather than leaving the client guessing.
One clear total in the right currency, with any tax charged shown as its own line. Two reasons: first, your books have to match the receipt exactly, and a lump sum that hides the tax makes that harder; second, your client may need the tax figure for their own records. If no tax applies, a simple total is fine — but never leave the client to guess whether tax is included. Say so: "Total (tax included)" or "Total + tax" removes all doubt.
Record the payment method — cash, bank transfer, card, or wallet — and state plainly whether the bill is settled or something is still owed. "Paid in full" closes the matter; "Balance remaining: $400" keeps it honest and prevents the awkward conversation where a client believes they've paid everything and you know they haven't. Partial payments are where most receipt disputes live, so spell out the remaining balance every time.
Most bad receipts fail in the same three ways. First, vague descriptions — a single line that says "services" or "misc" tells nobody anything later. Second, the wrong date — the invoice date instead of the payment date, which quietly corrupts your monthly records. Third, no copy kept — the client gets the only copy, and when they lose it, the payment effectively never happened as far as your records are concerned. Fix those three and your receipts do their job.
Either works, as long as the seven things above are on it and you keep a copy. Paper suits walk-in sales; a PDF suits everything else — it's searchable, easy to resend, and impossible to fade. Whichever you choose, keep your own copy: a receipt you can't produce later is a receipt you never had.
An invoice asks for payment; a receipt confirms payment arrived. Send the invoice first, then the receipt the moment the money lands — that order keeps your records clean and your clients confident. If payment is still owed, start with an invoice, not a receipt; a receipt for money you haven't received yet will confuse everyone, including you.

What's the difference between a receipt and an invoice?
An invoice asks for payment; a receipt confirms payment was received. You send the invoice first, and the receipt after the money lands. Most businesses keep both in their records.
Do I have to issue a receipt for every payment?
It's good practice for every payment, however small. A receipt protects you if a client ever claims they didn't pay, and it keeps your books complete. Skipping receipts for small cash payments is how bookkeeping gaps start.
What if I don't have the client's full address?
Use what you have — the client's name is the essential part. Add an address or email whenever you have one, since it helps the client match the receipt to their own records, but a missing address doesn't make a receipt useless.
Should a receipt show tax?
Yes, whenever tax was charged. Show the tax as its own line so the total matches your books exactly and your client can claim it correctly. If no tax applies, a simple total is fine.
How long should I keep copies of receipts?
Keep copies at least as long as your local tax rules require — rules differ by country, so check the retention period where you file taxes. Storing PDFs costs nothing, so keeping them longer than the minimum is the safe habit.
