Original, Duplicate, Triplicate Invoice Copies: GST Rule 48

Updated 12 November 2026 · By Ashok Sachdev · Source: Rule 48, Rule 55 and Rule 57 of the CGST Rules, Sections 35 and 36 of the CGST Act (CBIC)

Pre-printed GST bill books come with three colours of paper for a reason, and many shop owners still ask which copy goes where, whether a thermal printer counts, and what to do when a customer loses the bill. This guide answers those questions with the rule text behind each answer, so you can set up your bill book or billing software once and stop worrying about it.

Which copy goes to whom

For services, such as a mobile repair labour charge billed separately, Rule 48(2) asks for two copies: ORIGINAL FOR RECIPIENT and DUPLICATE FOR SUPPLIER. There is no transporter copy because nothing travels.

"Triplicate for supplier" means your own copy

The wording confuses people because in daily language "supplier" is the person you buy from. In the GST rules, the supplier is whoever issues the invoice. When you sell, you are the supplier, so "Triplicate for Supplier" is the copy you keep. When you buy from a distributor, the distributor keeps its triplicate, and the copy that reaches you is the original.

A quick way to remember it: original goes out with the customer, duplicate goes on the truck, triplicate stays in the drawer.

Do all copies need the same number?

Yes. The three copies are one invoice. They share the invoice number, date, items, rates and totals; only the marking at the top changes. Never give a copy its own number. Under Rule 46, each invoice needs a unique consecutive serial number in the financial year, and a copy with a new number would look like a second sale with its own tax. For the numbering rules (16 characters, allowed symbols, a new series each April), see GST invoice number rules.

Counter sales with a thermal printer: do you need three prints?

Most retail sales are walk-in, B2C and paid on the spot. The customer takes the goods, so no transporter copy is involved. The customer gets the printed bill, and the seller needs a record of it.

The rule speaks of copies, not of paper. Section 35 of the CGST Act and Rule 57 of the CGST Rules allow accounts and records to be kept in electronic form, with a proper backup. When your billing software stores every bill with its number, that stored bill is commonly treated as your copy, and shops do not print a second slip for the drawer. If your CA or your state's practice expects a printed office copy, print one; it costs a few paise of thermal paper.

Whatever you choose, keep records for 72 months from the due date of the annual return for that year (Section 36). On a computer or cloud account that means backups, not just one laptop; see shop billing data backup and is cloud billing software safe.

When goods travel: the transporter copy matters

If you deliver goods by your own tempo, a courier or a transporter, the duplicate copy should travel with them. An officer checking a vehicle looks for the invoice (or a bill of supply or delivery challan) and, where the value needs it, an e-way bill. Rule 138A lists the documents a person in charge of a vehicle must carry. Hand the driver the transporter copy, not the customer's original.

The e-way bill limit and how to generate one are in e-way bill rules 2026. Large businesses on e-invoicing follow Rule 48(4), which applies notwithstanding the copy rules above: their invoice is the one registered on the Invoice Registration Portal with an IRN and QR code. Most small shops are below the e-invoicing limit; the details are in GST e-invoicing for retailers.

Delivery challan: also in triplicate

When goods move without a sale, for example on approval, for job work or to your own godown, you use a delivery challan instead of an invoice. Rule 55(2) asks for three copies of the challan too: original for the consignee, duplicate for the transporter, triplicate for the consigner. The format and when to use one are in delivery challan under GST, and you can make one free with the delivery challan format tool.

Customer lost the bill: issue a duplicate copy, not a new bill

Customers come back for a bill for warranty, an office expense claim or a loan file. The right way:

1. Find the original sale by date, customer name or amount.
2. Reprint or resend the same invoice: same number, same date, same amounts.
3. Mark it clearly, for example "Duplicate copy" or "Reprint", so nobody mistakes it for a fresh sale.
4. Never cut a new invoice for an old sale. A new number would show the sale twice in your GSTR-1 and you would pay tax on it twice.

If the original bill itself was wrong (wrong GSTIN, wrong rate), a copy will not fix it; you need a correction. See how to cancel or amend a GST invoice.

Setting up your bill book or software

The fields every GST invoice must carry, whatever the number of copies, are in GST invoice format for retail shops. For B2B bills, where the buyer claims ITC from your original, see how to make a B2B GST invoice. If you are choosing paper size, read 58 mm vs 80 mm thermal printer and thermal vs A4 invoices.

Hindi mein short answer

सामान के GST बिल की तीन कॉपी होती हैं: पहली "Original for Recipient" ग्राहक के लिए, दूसरी "Duplicate for Transporter" गाड़ी के साथ जाती है, और तीसरी "Triplicate for Supplier" आपके (बेचने वाले के) पास रहती है। तीनों पर एक ही बिल नंबर और तारीख होती है। सेवा के बिल की सिर्फ दो कॉपी: ग्राहक और आप।
