FBR E-Invoicing in Pakistan: Guides by City & Business Type

FBR e-invoicing is a national requirement: every sales-tax-registered business in Pakistan must report taxable supplies to FBR's digital invoicing system in real time and issue a valid unique FBR invoice number (IRN) and QR code. The rules are the same countrywide, but the practical pressures differ by city and by business type. Use the guides below to find the version that fits you, or start with the full FBR e-invoicing compliance guide.

FBR e-invoicing by city

The mandate applies in every city — these guides cover the local business landscape and what it means for you:

• Karachi — Pakistan's largest commercial and port city: importers, corporates, and dense wholesale markets.
• Lahore — Punjab's industrial and commercial capital, spanning manufacturing, trading, retail, and services.
• Faisalabad — the textile capital: mills, processors, and garment exporters.
• Sialkot — surgical instruments, sports goods, and leather export supply chains.
• Islamabad — corporates, IT and services, contractors, and traders in the capital.
• Rawalpindi — a major wholesale and trading hub serving the wider region.

FBR e-invoicing by business type

How the rules play out depends on where you sit in the supply chain:

• Manufacturers — production billing, credit/debit notes, and protecting your buyers' input tax credit.
• Importers — how e-invoicing on local sales differs from customs clearance.
• Wholesalers & distributors — high invoice volume, credit sales, and fast-moving returns.
