What a Legally Correct GST Invoice Must Contain in Pakistan: An Audit-Ready Checklist
Article Content
Written by the Tejarify Product Team – based on data from 500+ retail and wholesale businesses across Pakistan.
Summary: A missing field on a GST invoice in Pakistan is not a minor error. It can trigger FBR audit notices, disqualify input tax claims for your buyer, and create legal liability. This checklist covers every required field.
Quick Answer
A legally valid GST invoice in Pakistan must include: the seller’s name, address, and STRN; the buyer’s name, address, and NTN or STRN for B2B; invoice number and date; description of goods or services; quantity and unit price; taxable value; GST rate and amount charged; total payable amount; and for POS transactions, a QR code. Missing any of these fields makes the invoice non-compliant under Sales Tax Act 1990.
Why GST Invoice Compliance Matters More Than Most Businesses Realise
A non-compliant GST invoice creates risk for both the seller and the buyer. For the buyer in a B2B transaction, a non-compliant invoice means they cannot claim input tax credit – they overpay tax and may blame you for the loss.
FBR has been actively auditing invoice compliance across major business sectors in Pakistan. Getting this right protects your business and your customer relationships.
The Complete GST Invoice Checklist for Pakistan
The following 17 fields are mandatory on every GST invoice issued by a registered business in Pakistan:
- Seller’s full legal business name
- Seller’s registered business address
- Seller’s Sales Tax Registration Number (STRN)
- Seller’s National Tax Number (NTN)
- Unique sequential invoice number
- Invoice date
- Buyer’s name and address
- Buyer’s NTN or STRN (mandatory for B2B transactions above threshold)
- Description of goods or services supplied
- Quantity supplied
- Unit price before tax
- Total taxable value
- Applicable GST rate (standard rate is 17% in Pakistan)
- GST amount charged
- Total invoice value including GST
- QR code linking to FBR verification (for POS transactions)
- 236G or 236H notation where advance tax applies
Common Mistakes Pakistani Businesses Make on GST Invoices
Mistake 1: Missing buyer NTN on B2B invoices – disqualifies the buyer’s input tax claim.
Mistake 2: Incorrect STRN – even a single digit error makes the invoice invalid.
Mistake 3: No sequential invoice numbering – FBR requires an unbroken sequence.
Mistake 4: Missing QR code on POS receipts – mandatory for all Tier-1 transactions.
Mistake 5: Informal abbreviations for item descriptions – FBR requires clear, unambiguous descriptions.
How to Make Sure Every Invoice Is Automatically Compliant
Manual invoice generation in Excel, Word, or a basic billing app almost always leads to compliance gaps. Fields are missed, QR codes are not generated, and sequential numbering breaks when someone creates an invoice offline.
Tejarify generates fully compliant GST invoices automatically for every transaction – retail POS and wholesale B2B. All 17 mandatory fields, correct QR codes, and automatic sequential numbering. No manual checking required.
