A web app is software your business runs on. It has logins, live data, payments and reports. It is not a website with a few buttons added. In Sylhet, most of this work goes to a junior who has never shipped one that held up with real users.
I am RH Fardin, a senior solo developer. I do web application development in Sylhet from start to finish, and I write the code myself. I build booking and instalment systems for Hajj and UK-route travel agencies around Zindabazar. I build sales and stock dashboards for restaurant groups owned from Bradford. I also build NRB property portals for flat developers and order apps for online sellers. Prices start from 50,000 BDT, with 50% advance and 50% on launch. You approve every screen in Figma first.

Here is how a web app project usually dies in Sylhet. A business owner needs real software. Maybe it is a booking system for a travel agency that runs on deposits and instalments. Maybe it is a stock dashboard the manager updates and the owner in the UK opens on his phone. Or an order portal that does not rely on a register and a WhatsApp group. This is the real work behind web application development in Sylhet.
The owner hands the job to whoever was cheapest, often a second-floor 'IT solutions' shop on Zindabazar or a part-timer. The app works in the demo. Then it falls apart the first week real data hits it. Logins break. Two staff overwrite the same record. The bKash flow marks unpaid orders as paid. The numbers do not add up, and the developer goes quiet. So people start searching for serious web application development Sylhet teams can trust. They have been burned once already.
A web app is a different animal from a website. Many people selling 'web application development' in Sylhet build you a website with a login page bolted on. A real app holds your data and enforces your rules. It handles many users at once, takes bKash or Nagad payments, and gives you reports a stranger can trust. Get the setup wrong at the start and the damage is real. It double-counts stock, lets two users wipe out each other's edits, or quietly ruins a month of bookings.
That is software work, not theme work. In Sylhet there is a second twist most developers ignore. The person who owns the business often lives in another country. The app cannot just work for the front desk in Sylhet. It also has to give the owner in London or Birmingham a live view he can trust. If it does not, it has not solved the real problem.
When you hire me, there is no agency layer and no junior you never meet. That matters more when half the people on the call are six time zones away. I run the scoping call where we map what your business really does. I do the data model, the Figma screens, the backend and the bKash, Nagad and SMS setup. I test your real edge cases and handle the launch. I am also on WhatsApp when your branch manager says a screen is confusing.
You get one senior operator with about five years of building web apps and sites for Bangladeshi businesses. There is one thread from first message to handover. With software, a small wrong choice early becomes a costly problem later. So one person who owns every decision matters more here than on a brochure site. Nobody relays your brief, and nobody passes the blame. That is the point.
Pricing is fixed and honest, in BDT, after one call. Builds start at 50,000 BDT for a focused app with one job, like a booking form with an admin panel, a catalogue with orders, or a lead system. 90,000 BDT covers a bigger app with user accounts, roles and reports. 1,50,000 BDT adds bKash or Nagad payments, stock or multi-branch logic, and the owner-abroad dashboard most Sylhet builds need. Fully custom software starts from 3,00,000 BDT, built from a blank scope to match how your business runs.
You always pay 50% advance and 50% on launch, by bKash, Nagad or bank transfer. You approve the full design before I write the app code. That step protects you from paying the second half for software you cannot use. A web app is priced on its logic, not its page count. So the real number comes after a short call about what it has to do.
Here are six things that set a properly built web app apart from a website with a login bolted on. Each one ties to how a Sylhet business works, often run from two countries.
Built to survive real data and real users, not just look right on a screen-share. Logins, roles, reports and payments hold up the week after launch, not just on launch day.
Most Sylhet apps I build serve an owner in the UK. I add a live dashboard he opens on his phone. It shows branch sales, stock, takings and dues. He stops finding out how the business did a month late.
I design the data model and rules before any screen is coded. So your app does not double-count stock, overwrite bookings or break reports later. The costly mistakes get stopped early, not patched.
Payments are set up and tested against the messy cases. Think failed payments, half-paid instalments, refunds and double clicks. Your numbers match up. This is standard from the 1,50,000 BDT tier, and scoped lower where it fits.
Your staff use it on a mid-range Android over local 4G. Your customers buy from a phone. So the app loads fast and works one-handed on the phone people really hold, not a developer's laptop.
No backend code starts until you sign off every screen in Figma. On launch you get the source code, database and server access. There is no lock-in, and the owner abroad never depends on one person's goodwill.
With a brochure website, a bad build is mostly about looks. It looks cheap and loads slow, but it does not lose you money on its own. A web app is different, because you put your business inside it. Once your stock, bookings, orders or payments live in the software, a weak build becomes a real business problem. I have cleaned up enough of these to know the pattern.
Stock counts drift until nobody trusts them. Two staff overwrite the same booking. A bKash flow marks unpaid orders as paid. Reports quietly miss a category, so the month's numbers are wrong. The owner saved 40,000 taka on the build. Then he spent triple that on lost stock, refunds and the rebuild he needed anyway. The cheap app did not fail loudly. It failed quietly, which is worse. You trust it until the day you cannot.
In Sylhet this gets sharper, because so many apps are paid for from abroad. The quote bends the moment a firm senses a brother in the UK is paying. You get a padded number and a half-built admin panel. Then the developer goes quiet once the advance clears, since the man who paid is six time zones away. I refuse to work that way. I build one app at a time and quote the same for a tea stall in Sobhanighat or a restaurant chain in East London.
I start with how your business really runs and what data you cannot get wrong. I plan for the edges, like a failed payment, a cancelled booking, or two users on one screen. Screens are approved in Figma before I write the backend. The price is fixed in BDT after one call. It runs from 50,000 BDT for a focused app to 1,50,000 BDT for a payment and dashboard system, and custom starts from 3,00,000 BDT. On launch you get the full source code, with nothing held hostage.

Straight answers to what Sylhet business owners ask me in the first WhatsApp message about web application development. Often the family abroad is listening in.
It depends on what the app has to do. Builds start at 50,000 BDT for a focused app with one job. 90,000 BDT covers a bigger app with user accounts, roles and reports. 1,50,000 BDT covers bKash or Nagad payments, stock or multi-branch logic, and the owner-abroad dashboard. Fully custom software starts from 3,00,000 BDT. You pay 50% advance and 50% on launch, by bKash, Nagad or bank transfer. The real number comes after a short call, and it does not grow because UK money is behind it.
A website mostly shows information, like your services and contact details. A web app does work. It has logins, stores your data and follows your business rules. It handles many users at once, takes payments and makes reports. Booking platforms, stock systems, order dashboards and NRB property portals are all apps. A lot of cheap 'web application development' in Sylhet is really a website with a login bolted on. It falls apart once real data arrives. If your business depends on its data, you need a proper app.
Yes, and for most Sylhet web apps I build that is the whole point. The owner abroad gets a live dashboard on his phone with branch sales, daily takings, stock, attendance and dues. He stops hearing about last month from a relative or a 2am call. Role-based logins keep it clean. The manager here runs his branch. The owner in London or Birmingham sees everything in one view. I talk with him directly on WhatsApp, IMO or Zoom, so nothing gets lost in between.
Yes. This is a common ask from the travel and Hajj agencies around Zindabazar. I build booking systems that hold a package across a deposit and instalments. They track who paid what, manage seats, and record bKash, Nagad or bank payments per booking. The hard part is the edge cases: a cancelled booking, a partial refund, a late instalment, or two staff selling one slot. A cheap build skips these. I test for them. Booking apps with payments sit in the 1,50,000 BDT tier.
Yes. I set up bKash and Nagad, plus SSLCommerz or AamarPay if you need cards. Then I test the cases that break: a payment that fails halfway, a wrong amount, a refund, a double click, or a late instalment. The goal is daily totals that match with no manual fixing. An owner abroad needs that before he trusts the dashboard. Apps with payments sit in the 1,50,000 BDT tier and up. On the first call I will tell you if you need full payments or just a payment check.
I built your app, so I fix it. You reach me on WhatsApp, not a ticket queue. Every build has a warranty window where real bugs are fixed for free. I know the code, so a fix that takes a new developer days often takes me an afternoon. You own everything, 100%. On launch I hand over the full source code on your own GitHub, plus the database, server access and setup notes. No forced monthly fee, no lock-in. A local Sylhet developer could take over on day one.
