This is the most confused question we get asked, and the confusion is reasonable. Pakistan taxes goods federally and services provincially, each authority has built its own integration regime, and the two now overlap in ways nobody designed deliberately.
The short answer: the test is what you sell and where, not which system you would prefer to use.
The dividing line
Sales tax on goods is federal, administered by FBR. Sales tax on services is provincial — the Punjab Revenue Authority, the Sindh Revenue Board, and their counterparts in Khyber Pakhtunkhwa and Balochistan.
If you sell goods, FBR digital invoicing applies. If you sell services, the relevant provincial authority applies. If you do both — a restaurant selling packaged goods alongside meals, a workshop selling parts and labour — you are dealing with more than one, and that is not an edge case.
What Punjab requires
The Punjab Revenue Authority operates the Electronic Invoice Monitoring System. It is mandatory for hotels, restaurants, coffee shops and marriage halls, and handwritten receipts are banned province-wide.
Enforcement is not theoretical. Fines run from Rs 400,000 to Rs 1,000,000, premises can be sealed for up to a month, and notices have gone to dozens of hotels, restaurants and marquees. If you run a venue in Punjab, this is the live obligation regardless of what happens federally.
What Sindh requires
The Sindh Revenue Board runs POS integration under its own online integration rules, and has sealed non-compliant restaurants in Karachi. The mechanism differs in detail from Punjab but the obligation is the same in kind: electronic invoicing, transmitted, for service providers in the province.
Where the overlap is becoming a problem
FBR's draft Chapter VIIA under SRO 288(I)/2026 would pull named service sectors — restaurants, marriage halls, clubs, hospitals, schools, couriers — into the federal system as well. Provincial tax authorities have formally objected, arguing they already mandate integration for exactly those businesses.
How that is resolved is above our pay grade. What it means practically is that a restaurant in Lahore could end up transmitting to two authorities, and should not be buying software that can only talk to one.
What to build against
Treat the tax authority as a configurable destination rather than a hard-wired endpoint. A system with the authority baked into its invoicing logic will need rebuilding every time the landscape shifts, and it has shifted twice in eighteen months.
The underlying data work is identical whichever authority receives it: clean item codes, buyer registrations in the right format, document types mapped, invoice numbering that does not repeat. Do that first — it is the part that takes time, and none of it is wasted.
Common questions
Do I need both FBR and provincial integration?
If you sell both goods and services, quite possibly. Goods are federal and services are provincial, and businesses doing both answer to more than one authority. Check your actual supply mix rather than assuming one regime covers you.
Which authority covers restaurants?
Restaurants supply services, so the provincial authority applies — PRA in Punjab, SRB in Sindh. FBR's draft SRO 288(I)/2026 would add a federal obligation if finalised, which is precisely what the provinces have objected to.
What happens if I integrate with the wrong one?
You remain non-compliant with the right one. Integration with FBR does not discharge a provincial obligation, and the provinces are actively sealing premises.
