About 41Stack

41Stack is a small software studio in Pakistan. We make two products: Postory (retail POS and inventory) and Fbrly (FBR digital invoicing).

We also take on integration and custom-build work for businesses that need something specific.

How we work

We pick problems we can ship a small, useful version of in a few weeks, not a few quarters.

We ship cloud-first because that's the cheapest way to keep things running and let customers reach them from anywhere.

Three kinds of work

Most of our time goes into Postory and Fbrly. The rest is custom work for businesses that need it.

Postory

Point of sale, stock, products, and sales reports for retail shops.

Fbrly

FBR digital invoicing with IRIS and PRAL, IRN and QR on every PDF, and stock and POs built in.

Custom builds

Integrations, automations, and small line-of-business apps for businesses with a specific need.

How we think about it

What we try to do

These aren't promises, just the lens we use when building.

Ship something small that works

A short cycle from idea to first useful version. Then improve.

Be the system your team forgets about

Stays out of the way. Doesn't break on a busy day.

Use the web first

Cloud-first because it's the cheapest way to keep things running and reachable.

Talk to actual users

Most of what we change comes from a customer email, not a roadmap.
