FOR AI AGENTS Your agent drafts the receipt, you approve it. No API key needed

Any software agent can pre-fill this receipt generator by opening a link with parameters in the URL fragment (after #). The fragment is processed by the browser and never sent to the server or included in referrers. No signup, no API key, no backend. The receipt builds itself client-side, ready to review and download as PDF. Full guide for agents → Example:

Private by construction, not by promise

Most quoting tools keep your business and client details on their servers. MonkeeTools runs entirely in your browser instead: your business profile, clients, and receipt history are stored only on this device, nothing is ever uploaded anywhere, and there is no account to create. Privacy here is not a policy, it is the architecture.

Payment receipts, explained

A receipt says paid. An invoice says pay.

A receipt is the document you send after the money arrives. It closes the loop on an invoice, answers "did you get my payment?" before it is asked, and gives your client something their accountant will accept. Here is what belongs on a receipt, when it is the wrong document, and how the generator above makes one in seconds.

A receipt does not ask for money. It closes the loop on a payment that already happened. Send it the day the money arrives.

The verdict in one glance

ReceiptMoney already receivedA thank-you with legal weight. It records what was paid, when, and how.
InvoiceA request for paymentThe bill you send before any money changes hands.
QuoteA price before the workAn offer. Nothing has been agreed or paid yet.

What goes on a receipt

  1. Your business name and contact details, so the client knows who confirmed payment.
  2. Your receipt number, in a sequence separate from your invoices (RCP-001, RCP-002).
  3. The date the payment arrived, plus the date you issued the receipt if they differ.
  4. The invoice or order number the payment settles, if there was one.
  5. A list of what was paid for, in plain language.
  6. The payment method: bank transfer, Zelle, Venmo, card, check, or cash.
  7. The total received, with currency. If you charge tax, show the tax line the same way your invoice did.

When a receipt is the wrong document

A receipt you can actually use

The generator at the top of this page is the template: it numbers each receipt in its own RCP- sequence, prints the invoice number it settles, the payment method and date paid, line items with tax, and exports a finished PDF in one click. No email gate, no signup, nothing uploaded. Scroll up, fill it in, send it.

Receipt questions, answered

What is a receipt?

A receipt is a document that confirms payment was received. It is issued after the money arrives, unlike an invoice, which is a request for payment issued before.

Do I have to send receipts to clients?

In most places freelancers are not legally required to send receipts, but business clients often need one for their own books, and sending one ends follow-up emails asking whether payment arrived.

What is the difference between a receipt and an invoice?

An invoice asks for money and is sent before payment. A receipt confirms money was received and is sent after payment. Many accountants want both on file.

How should I number receipts?

Use one simple sequence per year, separate from invoice numbers, such as RCP-2026-001, RCP-2026-002. This generator keeps its own RCP-001, RCP-002 sequence automatically, so receipts never collide with invoices or quotes.

Can I just mark my invoice as paid instead of sending a receipt?

For your own records that is fine, but a receipt is a standalone document your client can file with their accountant, so it never raises the question.

Should a receipt show the payment method?

Yes. Stating how the client paid, for example by bank transfer on a specific date, answers the follow-up question before it is asked and helps if a payment is ever disputed.
