Invoice vs receipt

The core difference

One invoice can be settled by many receipts (part payments), and one receipt can settle many invoices (a dealer paying three bills together).

From the buyer's side the pair works in reverse. The supplier's invoice becomes the buyer's purchase entry and the basis of any input tax credit; the payment the buyer makes is recorded as a payment voucher in their books, and the supplier's receipt is their proof that the money reached the right account. When a dispute arises months later, the buyer who kept both documents together, invoice and receipt for each bill, settles it in minutes.

The GST receipt voucher

When a registered supplier receives an advance before supplying, Rule 50 of the CGST Rules requires a receipt voucher. Its fields include:

• Supplier name, address and GSTIN.
• A serial number following the invoice rule: up to 16 characters, unique in the financial year.
• Date, and recipient name, address and GSTIN if registered.
• Description of goods or services, amount of advance, rate and amount of tax.
• Place of supply for inter-state supplies, and whether reverse charge applies.
• Signature.

For goods, GST is generally not payable on advances, so the tax line often shows nil or is not applicable; for services it is payable. Read GST on advances received. If the deal is cancelled and no invoice follows, a refund voucher records the money returned. This is general information, not tax advice.

Worked example: an advance for a service

An interior contractor in Bengaluru takes ₹1,18,000 as advance for a design job worth ₹5,00,000 plus GST.

GST of ₹18,000 is paid in the month the advance came; the invoice carries ₹90,000 in total, of which only the balance ₹72,000 is fresh liability when the invoice is reported.

A plain payment receipt

For payments against an existing invoice, a simple receipt is enough. A good one shows:

Writing the invoice it settles keeps bill-wise outstanding accurate; see bill-wise details.

Cash memo, bill, invoice, receipt: everyday words

In shops, a cash memo is both invoice and receipt: it records the sale and shows it was paid on the spot. For registered businesses, though, that document must still meet GST invoice rules. See cash memo vs tax invoice. A customer asking for a pakka bill usually means a proper GST tax invoice.

Cash receipts and the limits

Income-tax law restricts receiving large amounts in cash from a single person in a day or for one transaction or event, and limits cash expenses. The thresholds are set in the income-tax law, which was replaced by a new Act from April 2026, so check the current limits on incometax.gov.in or with your CA before accepting big cash payments. Issue a receipt for every cash payment you accept, however small.

Habits that keep receipts clean

1. Issue a receipt the same day money comes in.
2. Always link it to specific invoices, or note on account if the buyer has not said.
3. Use a separate series for receipt vouchers for advances.
4. Send the buyer a copy or an updated statement so both ledgers match.
5. For field collections, have the salesperson record each one at the shop, not at the end of the week.

Doing this with Tally and Cashflow OS

With Cashflow OS, receipt vouchers can be created from the phone through the connector, and salespeople can record what they collected with the collections module. Party ledgers and outstanding update after sync, and an updated statement can be sent on WhatsApp.
