Invoice vs Receipt: What's the Difference?

Key takeaways

• An invoice asks for payment before you are paid; a receipt proves payment after the money arrives.
• An invoice can act as a receipt once it is marked paid, with the payment date, method and a zero balance.
• In India, a GST-registered seller must issue a tax invoice for a taxable sale, and a receipt voucher when it takes an advance.

An invoice is a request for payment that a seller sends before the buyer pays. A receipt is proof of payment that the seller issues after the money arrives. The invoice opens the transaction by stating what is owed and by when; the receipt closes it by confirming the amount was paid.

So the invoice vs receipt difference is one of timing and purpose: an invoice shows money to be collected, and a receipt shows money already collected.

Invoice vs receipt example

A Pune design studio finishes a website for a client in the same state on 1 March, invoices it, and is paid by NEFT on 12 March. The two documents look like this:

An invoice can work as a receipt once it has been paid, but a receipt cannot replace an invoice. Until it is paid, an invoice proves only that money is owed, so on its own it is not proof of purchase.

To convert an invoice into a receipt, mark it 'Paid' and show the payment date, the payment method with a reference such as a UTR or card authorisation, and a balance due of zero. Online stores and subscription services usually work this way, sending one combined invoice and receipt after you pay. Most accounting software marks an invoice paid when you match the payment to it.

The reverse does not work. A receipt has no payment terms or due date and, in India, lacks the tax details a buyer needs to claim input tax credit (see how to claim ITC in GST). If a client who has already paid asks for an invoice, issue a proper one and mark it paid.

For a buyer, the safest proof of purchase is the paid invoice or receipt together with the bank or card record of the payment.

No. A tax invoice is the GST document a registered seller issues for a taxable sale, showing the tax charged, while a receipt only confirms that payment was made. For GST, the tax invoice is the document that counts.

• It carries details a receipt never has: both parties' GSTINs for a B2B sale, HSN or SAC codes, the place of supply and the tax split into CGST and SGST, or IGST.
• It records the GST charged and is the document a business buyer needs to claim input tax credit.
• For services it is due within 30 days of supplying the service; for goods, before or at the time of removal.
• A seller who cannot charge GST, such as a composition dealer, issues a bill of supply instead.
• For an export of services under a letter of undertaking, the invoice must state that the supply is for export without payment of IGST.

Why does a shop bill say 'Tax invoice'?

Because GST requires the tax invoice at the time of sale, and when you pay on the spot it also serves as your receipt. That is why a supermarket slip or an online order email is headed 'Tax invoice' even though you have already paid. For retail sales below ₹200 to unregistered buyers, a seller may instead issue one consolidated tax invoice at the end of the day, unless the buyer asks for one.

What if you are paid in advance?

Section 31(3)(d) of the CGST Act requires a receipt voucher, not a plain receipt, when you take an advance before supplying anything. For services, GST is due on the advance itself, so the voucher shows the tax rate and amount; advances for goods are not taxed at that stage. When you supply, you raise the tax invoice and adjust the advance against it. If the deal falls through, you issue a refund voucher.

A proforma invoice is different again: it is a quote sent before the sale and carries no GST liability; see proforma invoice vs tax invoice.

It depends on how the money moves. When payment follows an invoice, as in most business-to-business work, you need both; when the buyer pays at the moment of sale, one document can do both jobs.

Even when the law asks only for the invoice, many clients' accounts teams want a receipt before they close a payable. Employees claiming expenses usually need a receipt or a paid invoice too, because an unpaid invoice does not prove they spent the money.

An invoice needs enough detail to be paid and taxed correctly; a receipt needs enough to prove the payment and tie it to the invoice. Under GST, a tax invoice should show:

• The word 'Invoice' or 'Tax invoice', a unique number and the date. The number runs in one series per financial year and can be up to 16 characters.
• The seller's name, address and GSTIN, and the buyer's name, address and, for a B2B sale, GSTIN. Without the buyer's GSTIN, the buyer cannot claim input tax credit.
• Each item with its HSN or SAC code, quantity, rate and value.
• The place of supply and the GST rate and amount: CGST and SGST for a sale within a state, IGST between states.
• The total due, the due date and how to pay, such as bank details or a UPI ID.
• The seller's signature or digital signature.

A receipt needs less: the word 'Receipt', a receipt number and date, both parties' names, the invoice number it settles, the amount paid including tax, the payment mode with its reference, and any balance left. Quoting the invoice number is what lets both sides match the payment in their books.

Businesses with turnover above ₹5 crore must also generate a GST e-invoice, with an IRN and QR code, for B2B sales; see e-invoice limit.

They mark different points in the same sale: a quotation before you agree, an invoice or bill when payment is due, a receipt once it is paid, and a statement that sums up a period. Of these, only the invoice, or a bill of supply, counts for GST.

The word also depends on your side of the sale: an invoice you send is income, while a bill you receive from a supplier is an expense. For that pair in detail, see invoice vs bill.

When a client abroad pays an Indian business, the proof that matters is the Foreign Inward Remittance Advice (FIRA) from the bank or payment provider. It records the foreign amount, the rupee amount and the purpose of the payment, and it backs up your export invoice in GST and bank records.

You can still send the client a receipt so it can close its payable, but in your own books the FIRA is what shows the export earnings arrived. Check that its purpose code matches the service you invoiced, such as P0802 for software services.

A plain 'payment received' note or a platform email is not enough for this. See FIRC vs FIRA for how the two certificates differ; Xflow, for example, issues an eFIRA within 24 hours for every international transaction.
