FAQ

Common questions

How much does api development cost?

It depends on scope. Most projects start from ৳1.5 lakh. After a short discovery call we send a fixed quote broken into milestones.

How long does it take?

Typical timeline is 1–3 months. You see working software at the end of every two-week sprint, so progress is never a guess.

Can you work with our existing systems?

Yes. We integrate with ERPs, payment gateways, telecom and legacy systems, and migrate your data as part of the project.

Who owns the code and data?

You do. Source code, data and documentation are handed over at launch.

What happens after launch?

We offer SLA-backed support and maintenance with a named team that already knows your system.
