Built by one senior developer, not a junior team
Why 'cheap' usually backfires on web apps in Bangladesh
A static website that breaks looks ugly. A web app that breaks loses orders, double-books visits, or leaks customer phone numbers to the wrong vendor. That is why "cheap web application development in Bangladesh" is the most risky phrase a founder can type into Google. The 10,000 BDT quote in a Facebook group is not building you software. It is gluing a free WordPress plugin to a database and praying.
I have rebuilt enough of those projects from scratch to know where the cracks appear. There is no input checking, no proper user roles, no error handling, and no backups. The database design falls over the moment you cross 500 records.
Affordable should mean small scope done properly, not big scope done badly. Say a Dhaka coaching center asks me for a student management app under 1 lakh BDT. I do not try to sell them five modules. I cut it to two. The first is enrolment with bKash payment confirmation. The second is an attendance dashboard their teachers can really use on their phones. That is a real product they can launch next month. The other three modules can come in version two, after the first one earns them money.
I have built web apps for Bangladeshi clients for about 5 years. I work full-stack and hands-on, with no outsourcing. My low cost web application development tier starts at 50,000 BDT. It is meant for a focused MVP: one user role, three to five core screens, one payment integration, and one notice channel, either SMS or email.
The 90,000 BDT and 1,50,000 BDT tiers add admin panels, multi-role access, reporting dashboards and proper deployment. A real multi-user SaaS or company-wide tool moves into the custom tier, from 3,00,000 BDT. I will tell you that upfront. I will not promise the moon at the cheap-tier price.
Here is what you get from me at the low end. A working app on a real domain. Source code in your own GitHub or Bitbucket. A deployment you can hand to any future developer. A design you approved before the first line of code. There is no black-box hosting on my server that holds you hostage. There is no "maintenance contract" you must keep paying, or the app disappears.
