A web application is software your business runs on — logins, live data, payments, reports — not a website with a few buttons added. In Sylhet, most of it gets handed to a junior who has never shipped one that survived real users.
I am RH Fardin — a senior solo developer doing web application development in Sylhet end to end. I write the code myself: the data model, the backend, the admin panel, the bKash or Nagad integration, the deployment. Booking and instalment systems for the Hajj and UK-route travel agencies around Zindabazar, branch sales and stock dashboards for restaurant groups owned from Bradford, NRB property and lead portals for flat developers, order and enquiry apps for the city's online sellers. A web app holds your business inside it, so it has to be engineered — not themed. From 50,000 BDT, 50% advance and 50% on launch, with every screen approved in Figma before a line of backend goes in.

Here is how a web app project usually dies in Sylhet. A business owner needs real software — a booking system the travel agency can run across deposits and instalments, a stock dashboard the restaurant manager updates and the owner in the UK can open on his phone, an order portal that does not depend on a register and a WhatsApp group.
They hand it to whoever was cheapest, often a second-floor 'IT solutions' outfit on Zindabazar or a part-timer, and they get a thing that works in the demo and 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 report numbers do not add up — and the developer goes quiet.
That, not a slogan, is why people start searching for serious web application development in Sylhet: they have already been burned by the cheap build once.
A web application is a different animal from a website, and most people selling 'web application development' in Sylhet are quietly building you a website with a login page bolted on. A real app has state — it holds your data, enforces rules, handles many users at once, processes payments through bKash or Nagad, and produces reports a stranger can trust.
Get the architecture wrong at the start and it does not just look bad: it double-counts your stock, lets two users clobber each other's edits, or quietly corrupts a month of bookings. That is software engineering, not theme customisation, and in Sylhet there is a second twist most developers ignore — the person who owns the business is frequently in another country.
The app cannot just work for the front desk in Sylhet; it has to give the owner in London or Birmingham a live, trustworthy view of what is happening here, or it has not solved the real problem.
When you hire me, there is no agency layer and no junior you never meet — which matters double when half the people on the call are six time zones away. I am the scoping call where we map what your business actually does, the data model, the screens in Figma, the backend logic, the bKash or Nagad and SMS integration, the testing against your real edge cases, the deployment, and the person on WhatsApp when your branch manager says a screen is confusing.
One senior operator, around five years building web applications and sites for Bangladeshi businesses, one thread from first message to handover. For software — where a small wrong decision early becomes an expensive problem later — that single point of accountability matters more than it does for a brochure site. There is nobody to relay your brief through and nobody to pass the blame to, which is exactly the point.
Pricing is fixed and honest, in BDT, after one call. Web app builds start at 50,000 BDT for a focused single-purpose app — a booking form with an admin panel, a catalogue with orders, a lead or enquiry system. 90,000 BDT covers a multi-feature app with user accounts, roles and reporting. 1,50,000 BDT covers a larger system with bKash or Nagad payments, inventory or multi-branch logic, and the owner-abroad dashboard most Sylhet builds need.
Genuinely custom software — built from a blank scope to match exactly how your business runs, not forced into a template — starts from 3,00,000 BDT. Always 50% advance and 50% on launch — bKash, Nagad or bank transfer — and you approve the full design before I write the application code. That last part is what 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.
Six things that separate engineered web app development from a website with a login bolted on — each one tied to how a Sylhet business, often run from two countries, actually works.
Built to survive real data and real users, not just look right in a screen-share. Logins, roles, reports and payments that hold up the week after launch, not just on launch day.
Most Sylhet apps I build serve an owner in the UK. I wire in a live dashboard he opens on his phone — branch sales, stock, takings, dues — so 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 corrupt reports later. The expensive mistakes get prevented, not patched.
Payments wired in and tested against the messy cases — failed transactions, half-paid instalments, refunds, double-submits — so your numbers reconcile. Standard from the 1,50,000 BDT tier, scoped lower where it fits.
Your staff use it on a mid-range Android over local 4G, and your customers buy from a phone. The app is built to load fast and work one-handed on the device people actually 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 — no lock-in, and the owner abroad never depends on one person's goodwill.
With a brochure website, a bad build is mostly cosmetic — 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. The moment your stock, your bookings, your orders or your payments live in the software, a weak build stops being an aesthetic problem and becomes an operational one.
I have cleaned up enough of these to know the pattern: stock counts that drift until nobody trusts them, two staff overwriting the same booking, a bKash flow that marks unpaid orders as paid, reports that quietly miss a category so the month's numbers are wrong. The owner saved 40,000 taka on the build and then spent triple that in lost stock, refunded customers and the rebuild he needed anyway.
The cheap app did not fail loudly — it failed quietly, which is worse, because you trust it until the day you cannot.
In Sylhet there is a sharper version of this, because so many of these apps are funded sight-unseen from abroad. The quote bends the instant a firm senses there is a brother in the UK paying — an inflated number, a half-built admin panel, and a developer who goes quiet once the advance clears, knowing the man who paid is six time zones away and cannot drop in to chase the work. That is the lane I refuse to play in.
I build one web application at a time, I quote the same number whether you are funded by a tea-stall in Sobhanighat or a restaurant chain in East London, and I start where it actually matters: how your business really runs, what data you cannot afford to get wrong, and what happens at the edges — the failed payment, the cancelled booking, the two users hitting the same screen.
The architecture is settled and the screens are approved in Figma before I write the backend, the price is fixed in BDT after one call — from 50,000 BDT for a focused app, 1,50,000 BDT for a payment-and-dashboard system, custom from 3,00,000 BDT — and on launch you get the full source code with nothing held hostage.
What you actually want from web application development in Sylhet is one senior developer who priced you straight, tested against your real edge cases, and will still answer WhatsApp when something needs fixing a year after launch. That is the whole product.

Straight answers to what Sylhet business owners ask me on the first WhatsApp message about web application development — usually with the family abroad listening in.
It depends on what the app has to do, but my builds start at 50,000 BDT for a focused single-purpose web app — a booking system with an admin panel, a catalogue with orders, a lead or enquiry tool. 90,000 BDT covers a multi-feature app with user accounts, roles and reporting. 1,50,000 BDT covers a larger system with bKash or Nagad payments, inventory or multi-branch logic, and the owner-abroad dashboard most Sylhet builds need.
Genuinely custom software, built from scratch to match how your business runs, starts from 3,00,000 BDT. Payment is always 50% advance, 50% on launch — bKash, Nagad or bank transfer. A web app is priced on its logic, not its page count, so the honest answer to 'koto taka' comes after a short call — and it does not quietly grow because there is UK money behind it.
A website mostly shows information — pages about your company, services, contact. A web application does work: it has logins, stores and updates your data, enforces business rules, handles many users at once, processes payments, and produces reports. Booking platforms, inventory systems, order dashboards, NRB property portals — those are apps. The difference matters because an app has to be engineered, not just designed. A lot of 'web application development' offered cheaply in Sylhet is really a website with a login bolted on, which falls apart the moment real data and real users hit it. If your project holds data your business depends on, you need an app built properly, not a dressed-up website.
Yes, and for most Sylhet web apps I build that is the whole point. I wire in a real-time dashboard the owner abroad opens on his phone — branch-wise sales, daily takings, stock, attendance, dues — so he stops finding out how the business did a month late from a relative or a 2am phone call. Role-based logins keep it clean: the manager here sees and runs his branch, the owner in London or Birmingham sees everything consolidated. And I deal with him directly across the time difference on WhatsApp, IMO or Zoom — no account manager relaying messages and losing details between Sylhet and the UK.
Yes — this is core web app work and a common ask from the travel and Hajj agencies around Zindabazar. I build booking systems that hold a package across deposit and instalments, track who has paid what, manage seats or slots, and record bKash, Nagad or bank-transfer payments against each booking. The hard part is the edge cases — a cancelled booking, a partial refund, an instalment paid late, two staff selling the same slot — and that is exactly what a cheap build skips and what I test for. Payment-driven booking apps sit in the 1,50,000 BDT tier; a simpler enquiry-and-booking tool can fit lower depending on scope.
Yes. When your app needs to collect money I integrate bKash and Nagad — and SSLCommerz or AamarPay if you need cards — and test them against the cases that actually break: a payment that fails halfway, a customer who pays the wrong amount, a refund, a double-submit, an instalment that lands a day late. The point is not that it works once in a demo; it is that your daily totals reconcile with no manual fixing, which is what an owner abroad needs before he will trust the dashboard.
Payment-enabled apps sit in the 1,50,000 BDT tier and up, and in the first call I will tell you straight whether you need full payment integration or just a payment-confirmation flow.
The person who built your app — me — is the one who fixes it, reachable on WhatsApp, not a support-ticket queue. Every build includes a warranty window where genuine bugs are fixed at no charge, and because I wrote the code and know exactly how it is structured, a fix that takes an unfamiliar developer days usually takes me an afternoon. You own everything, 100%: on launch I hand over the full source code (pushed to your own GitHub), the database, the server access and deployment notes.
No forced monthly retainer, no lock-in. If you decide next year to hire a local Sylhet developer to take over, they have everything they need on day one — which matters even more when the owner is abroad and cannot depend on one person's goodwill.
