Sindh tax rules and your software
Businesses in Karachi that provide taxable services register with the Sindh Revenue Board (SRB), under the Sindh Sales Tax on Services Act, 2011. That has a practical consequence when you choose billing or ERP software: the invoices it produces must meet SRB's rules.
The Sindh Finance Act, 2026, in force from 1 July 2026, made this explicit for software makers. It added a penalty of between one hundred thousand and one million rupees for any person who designs, develops, customises or supplies invoicing software that issues invoices not conforming to rule 29(1) of the Sindh Sales Tax on Services Rules, 2011, or rule 6 of the Sindh Sales Tax Special Procedure (Online Integration of Business) Rules, 2022 (source: Sindh Finance Act, 2026, last verified 22 October 2026).
What that means for you:
- Say at the start if you are SRB-registered, and whether you are required to integrate your invoicing online.
- Ask your developer how invoices will meet the SRB rules, and get the answer in writing as part of the scope.
- Check the invoice format with your tax advisor before the system goes live.
For federal sales tax and income tax, the same principle applies: tell your developer which rules you are under before anyone writes code.
Why work with a Karachi team
- Your time zone. Pakistan Standard Time, UTC+5, all year: your working day is ours.
- Local practice built in. Our products already handle Pakistani payroll tax, EOBI and provident fund rules, bank files for Pakistani banks, plot files and installments, and FBR, SRB, PRA, KPRA or BRA rates on invoices.
- Software you can see first. Most projects start from a live product, not a blank page.
- Plain contracts. Scope, ownership of code and data, and support are agreed in writing before work starts.
What it costs
Price depends on scope, integrations and how much data has to move. Our custom software cost guide collects the prices Pakistani and international firms publish, and our product subscriptions are on the pricing page. For a custom build, we quote per project, in writing, and reply to a brief within one business day.
How to start
Send us a short brief: what the business does, how many people will use the system, the work that takes the most time today, and the systems you already use. If you are an agency with clients of your own, see how we work as a development partner for agencies.
