Every counter sale needs a paper trail. The cash memo is the simplest one there is: proof that goods changed hands and cash was received, in one small document. This guide covers the standard cash memo format, how it differs from an invoice and a receipt, what GST expects of it — and a free way to make clean, printable cash memos without designing anything in Word.
The standard cash memo format
A complete cash memo carries:
- Seller details — business name, address, phone, and GSTIN if registered.
- Memo number and date — a serial number unique within your business, and the sale date.
- Item lines — description, HSN/SAC (if GST applies), quantity, unit, rate and amount.
- Discount — shown before tax, if any.
- GST — the rate and the CGST + SGST split (same state) or IGST (inter-state), when tax is charged.
- Grand total — in figures and, ideally, in words to prevent tampering.
- Payment mode — cash, UPI, card — plus a reference number for digital payments.
- Signature or stamp — of the seller or the authorised person.
Cash memo vs invoice vs receipt
The three get mixed up constantly, but the distinction is simple. An invoice asks for payment — it is issued for credit sales and payment follows later. A cash memo records a spot sale — payment happened at the counter, nothing is outstanding. A receipt acknowledges a payment against an earlier invoice. If you sell on credit, read our GST invoice format guide — that document has stricter, legally prescribed fields.
GST on cash sales
A GST-registered seller charging tax on a cash sale must show the rate and the correct split — CGST + SGST when buyer and seller are in the same state, IGST across states. For small B2C sales under ₹200, GST law permits a consolidated invoice at the end of the day instead of one per sale. Unregistered sellers issue plain cash memos with no tax fields at all.

Frequently asked questions
What is a cash memo?
A cash memo is the document a seller issues for a cash (spot-payment) sale. It records what was sold, the quantity, rate and total, and acts as proof of purchase for the buyer and a record of sale for the seller. It is common for over-the-counter retail and small purchases.
What is the difference between a cash memo and an invoice?
An invoice is a demand for payment — it is issued first and payment may follow later (credit sale). A cash memo is issued when payment happens on the spot, so nothing is outstanding. Legally, a GST-registered seller's tax invoice has prescribed fields under CGST Rule 46; a cash memo for small B2C sales is simpler.
What should a cash memo format contain?
Seller name and address (plus GSTIN if registered), a serial number and date, item-wise description with quantity, rate and amount, any discount, the GST rate and split if tax is charged, the grand total (ideally in words), and the payment mode. A signature or stamp adds authenticity.
Is a cash memo valid for GST?
For B2C sales below ₹200 a registered seller need not issue a full tax invoice for each sale (a consolidated invoice at day-end is allowed). Above that, or when the buyer asks, a tax invoice with GSTIN and HSN/SAC is the safe course. If the seller charges GST on a cash memo, the CGST/SGST or IGST split must be shown.

Yes. Apna Invoice includes a free cash memo maker: itemised lines with HSN/SAC, automatic GST split, discount, payment mode, amount in words, and a printable PDF — plus every memo flows into your expense ledger automatically.
