TL;DR

A receipt is issued after payment — it confirms money changed hands. Unlike an invoice (which requests payment), a receipt acknowledges that a transaction is complete.

Key Points

✓

Receipts are proof of payment and are critical for client expense reporting and tax deductions

✓

Unlike an invoice, a receipt is issued after the payment has cleared, not before

✓

Business owners should retain all receipts for business expenses as supporting documentation for tax deductions

✓

For services, a receipt typically references the original invoice number it corresponds to

Invoice vs. Receipt: Key Differences

An Invoice says 'you owe me money.' A receipt says 'you paid me money.' The invoice comes first, requesting payment for services rendered. The receipt comes after, confirming the payment was received. In a typical freelance workflow: you send an invoice, the client pays it, and you issue or email a receipt as confirmation¹. Some clients — particularly those who need to submit expenses to their employer or report business costs for tax purposes — specifically request receipts to document their payments.

When to Issue a Receipt

You should issue a receipt whenever a client pays an Invoice, especially for larger transactions. In retail or service environments with point-of-sale systems, receipts are automatic. For freelancers and service businesses, you can send a simple confirmation email after payment or a formal receipt document. Good receipt management also helps you reconcile your Accounts Receivable records — once a receipt is issued, the corresponding invoice should be marked as paid in your accounting system.

Keeping Receipts for Tax Purposes

You also receive receipts from your own vendors — for software subscriptions, office supplies, equipment, travel, and other business expenses. These incoming receipts are your evidence for tax deductions. The IRS and most tax authorities require receipts to substantiate deductible expenses². Keep digital copies organized by category and date — accounting software or even a dedicated folder in cloud storage makes this simple. Missing receipts during an audit can result in disallowed deductions and additional tax owed.
