In focus
The part of the price most Chattogram quotes leave out: year two
Here is the honest breakdown almost no app firm in Agrabad or GEC puts in writing before you've paid the advance. After launch, an app has running costs — and what they are depends entirely on the tier you chose, which is exactly why I tie them to the price up front.
A 50,000 BDT installable web app is the cheapest to keep alive: you pay for hosting and a domain, and that's roughly it — no Apple account, no Google fee, no store review cycles, because it lives on the web and installs to the home screen.
Step up to native iOS and Android in the custom tier and the running costs change shape: Apple's developer account is a yearly fee that, if it lapses, pulls your app off every iPhone in Chattogram; Google's is a one-time fee; and two codebases means more maintenance than one. None of that makes native wrong — for the right logistics or wholesale case it's worth it — but you deserve to see those numbers beside the build price, not discover them at renewal.
Then there's the cost that scales with success: payment. A manual 'pay to this bKash number' block is nearly free and sits inside the 50,000 BDT floor. But a real in-app gateway — bKash, Nagad or SSLCommerz handling checkout, confirmation and reconciliation — carries a per-transaction cut the provider takes on every order, separate from anything I charge. That's not a hidden fee I'm adding; it's the gateway's standard rate, and the more you sell the more it adds up, so you should factor it in from day one.
The same logic runs through every line: maintenance you can do yourself versus pay me for, extra admin screens, integrations with your existing inventory or a courier API. My job isn't to hide these so the headline mobile app development price in Chattogram looks tiny — it's to put the full sum in front of you, build plus run, so the decision is yours with both eyes open.
That transparency is the whole reason a port-city business hires one accountable person instead of a firm that only shows you the part of the bill that sells.
