The best custom software development company in Sylhet is the one that builds a system the manager in Zindabazar and the owner in London can both open and trust the same minute.
I am RH Fardin — a senior solo developer who scopes, designs, builds and ships custom software for Sylhet businesses end to end. No sales-to-junior handoff, no twenty-desk Dhaka office charging you for its rent. The multi-branch restaurant whose owner runs it from a curry house in Bradford, the real-estate developer selling flats to NRBs across three countries, the travel agency juggling Hajj, Umrah and UK-route bookings, the remittance-linked retail group on Bandar Bazar: you walk me through how the work actually happens, and I build the software that runs it — visible to the office here and the family abroad at once. From 50,000 BDT, full design approved before code, 50% advance and 50% on launch.

Most Sylhet owners who message me about custom software have a problem no template was built for: the person who runs the business and the person who owns the business are in two different countries. The branch manager in Sylhet records sales in a register and a WhatsApp voice note. The owner — in Whitechapel, in Manchester, in a restaurant kitchen in Bradford — finds out how the business did last month when a relative gets around to telling him, or when the cash doesn't add up and a phone war starts at 2am Sylhet time. Excel files get emailed back and forth and disagree. Nobody abroad can actually see the stock, the daily takings, the staff attendance, the dues. That distance and that mistrust is the real thing custom software solves here — and the best custom software development company in Sylhet, for a business like this, is whoever sits down and understands that two-country reality first, not whoever quotes the fastest.
Here is what makes the Sylhet software brief its own thing, and why a tool built for a single-owner Dhaka shop will not fit it. Sylhet's economy is wired to the diaspora end to end: multi-branch restaurants and food businesses backed by UK-side owners, real-estate and flat developers selling to NRBs who never set foot on site before they buy, travel and Hajj agencies running packages that cross the UK-Bangladesh line, remittance-linked retail, private clinics and diagnostics serving returning families. The software these businesses actually need is operational and remote-visible: branch-wise sales and stock the owner abroad can open on his phone in real time, a property and lead system that shows an NRB buyer his booking and payment status from London, a booking engine that holds a Hajj or UK-route package across deposits and instalments, role-based logins so a manager sees his branch and the owner sees everything. None of that comes out of a box. Custom software development in Sylhet, done right, is shaped around a business run from one country and owned from another.
When you hire me, there is no chain for your requirements to get lost in — which matters double when half the people on the call are six time zones away. I am the scoping call, the user flow, the screens in Figma, the database, the backend code, the bKash or Nagad integration, the SMS gateway, the deployment, and the person who picks up on WhatsApp when your branch manager says a screen is confusing. One senior operator, around five years building custom software and web apps for Bangladeshi businesses, one thread from first message to handover. In a Dhaka software house the senior who pitches you is on the next sale by the time a junior opens your project; your brief gets relayed through a salesman, a project manager and a coder, and the owner abroad — who is paying — ends up furthest from the truth of his own build. With me, the person who agrees the scope is the person who writes the code, and he gets on calls across the UK-Sylhet time difference himself.
Let me be honest about where I am genuinely the best fit, because for top custom software development in Sylhet the word 'best' should mean something specific, not a slogan. My zone is small-to-mid custom software for Sylhet businesses that need a clean admin panel, real branch and role separation, reporting an owner abroad can trust, and BD payment and SMS integration: multi-branch sales and inventory for restaurant and retail groups, property and NRB-lead systems for flat developers, booking and instalment systems for travel and Hajj agencies, appointment and report tools for clinics, HR and payroll for a few hundred staff. Pricing is in BDT and fixed after one call. Genuine custom software with a database, admin panel and user roles starts from 3,00,000 BDT. Smaller scoped tools and lightweight web apps fit my 90,000 or 1,50,000 BDT tiers when the scope allows, and the smallest engagement is 50,000 BDT. Always 50% advance, 50% on launch — bKash, Nagad or bank transfer — and you approve the full design before a single line of code is written. If you need a 300-screen ERP for a 5,000-worker factory, I will tell you straight to hire a larger team.
The 'best' tag should mean specifics, not a tagline. Here are six things a serious Sylhet business gets from me that most local software shops quietly skip.
Live branch sales, stock, takings and dues the owner in the UK can open on his phone in real time. The remote owner stops finding out how his Sylhet business did a month late, and the 2am phone wars over the numbers stop.
Proper multi-branch separation with role-based logins — each Sylhet manager sees only his branch, the owner sees everything consolidated. Built for restaurant, retail and clinic groups, not faked by giving everyone the same admin password.
For flat developers selling to non-resident buyers: a system where an NRB in London sees his unit, booking and payment status himself, and your sales team works one lead pipeline instead of scattered WhatsApp threads across time zones.
Payment integration for bKash Merchant, Nagad, SSLCommerz and AamarPay is standard scope — the OTP flows, IPN callbacks, refund and reconciliation cases done before, not learned for the first time on your project.
You approve every screen in Figma before I write line one of backend. If a flow does not match how your branch manager, accountant or front desk actually work, we fix it on paper, not in production after you have paid.
On launch you get the source code, the database, the server access and the documentation. Hire a local developer any year you like — nothing about your software is held hostage, and the owner abroad never depends on one person's goodwill.
There is a specific thing that happens to software pricing in Sylhet that I rarely see anywhere else: the quote bends the instant the firm senses there is a brother in the UK paying. Walk along Zindabazar and you will pass 'IT solutions' signboards on the second floor of half the buildings — usually a sales person, a junior who learned to code off YouTube, and a number that doubles when foreign money is in the room, because they know the investor abroad cannot drop in to chase the work or argue the bill. For a custom software project, where the owner is funding it sight-unseen from London, that risk is sharp: an inflated quote, a half-built admin panel, and a developer who goes quiet once the advance clears, knowing the person who paid is six time zones away. 'Best' here is not about who has the biggest office. It is about who quotes the same number whether you are funded by a tea-stall in Sobhanighat or a restaurant chain in East London, and who treats the owner abroad as the real client, not as a wallet that can't see the work.
That is the lane I work in, and it is why I refuse to quote a custom job in 24 hours the way most do. Before any number, I want 30 to 60 minutes on a call — and I will do it across the UK-Sylhet time difference so the owner abroad is actually on it, not relayed to later — where you both walk me through how the work happens now: which branch records sales how, where the NRB buyer's payment status gets lost, what specifically the owner in Bradford cannot see today and wishes he could, how a Hajj booking moves from deposit to final instalment. From that I write a one-page scope, you sign it, and that becomes the contract; new requirements mid-build get negotiated openly, never sprung as inflated 'change requests' at the end. Design is approved in Figma before I write backend code, and the price is fixed in BDT after that one call — custom software from 3,00,000 BDT, smaller tools from the 50,000 BDT floor, 50% advance and 50% on launch by bKash, Nagad or bank transfer. On launch you get the full source code, database and server access with 30 days of free fixes for genuine bugs, plus Bangla-English training videos your branch staff can rewatch. If you want the best custom software development company in Sylhet by the only test that matters — software your team here is still using and your owner abroad still trusts a year later — what you want is one senior person who priced you straight and learned your two-country business before he built for it.

Straight answers to what Sylhet business owners ask me on the first WhatsApp message about custom software — usually with the family abroad listening in.
Genuine custom software with a database, admin panel, user roles and at least one payment integration starts from 3,00,000 BDT. Smaller scoped tools — a single-branch stock and sales tracker, a property-lead web app, a basic booking tool — sometimes fit my 90,000 or 1,50,000 BDT tiers, and the smallest engagement is 50,000 BDT. The exact number depends on how many branches and user roles, which integrations (bKash, Nagad, SMS, accounting), whether the owner abroad needs a real-time dashboard, and whether you also need an Android app. I quote one fixed price after a single scoping call — not a guess over the phone, and not a number that quietly grows because there is UK money behind it.
Because you are almost never buying the same thing — and in Sylhet there's a second catch: that 50,000-taka quote often climbs once the shop learns there's a brother in the UK paying. A cheap quote is usually a reskinned stock template or a version one with no real plan for live data, multi-branch separation, payment integration or the owner-abroad dashboard you actually need. It works for a demo and breaks the moment real branches, real NRB buyers and real money hit it — and the developer is frequently gone quiet by then. Real custom software is designed around your two-country operation from a blank scope, built and supported by the senior who scoped it, at a price that does not move. If a cheap option genuinely fits I'll tell you so honestly — but for a multi-branch or diaspora-funded business it rarely does.
Yes to both, and honestly that is the whole point for most Sylhet builds I do. I build 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. And I run the project across both sides myself: the manager here for day-to-day detail, the owner in London or Birmingham for approvals and budget, with calls on WhatsApp, IMO or Zoom across the time difference. No account manager, no junior relaying messages and losing things between Sylhet and the UK. The person who builds your software is the person on the call with the man paying for it.
Yes — for a Sylhet real-estate developer selling to non-resident buyers this is exactly the kind of brief I scope carefully. I build unit and inventory management (which flats are available, booked, sold), a lead and sales pipeline so enquiries from abroad don't scatter across WhatsApp threads, and a buyer portal where an NRB in London or New York sees his own unit, booking status and payment schedule without phoning the office. Payment milestones, instalment tracking and bKash, Nagad or bank-transfer recording are built in. We scope it around how your buyers actually move — most of them deciding from another country before they ever see the building.
Yes, and multi-branch is one of the briefs I'm best at for Sylhet. I build branch-wise sales and stock with role-based logins — each branch manager sees and runs only his outlet, while the owner sees every branch consolidated in one dashboard, including the one abroad. That covers daily takings, inventory and reorder, staff attendance, supplier and party ledgers, and dues. The point is one source of truth instead of three registers and a WhatsApp group that only agree by accident — so the owner in the UK can trust the numbers without flying back to count cash himself.
You own everything, 100%. On launch day I hand over the full source code (pushed to your own GitHub or Bitbucket), the database backup, server access credentials, deployment instructions and a short technical manual — plus 30 days of free fixes for genuine bugs and Bangla-English training videos your branch staff can rewatch. I do not lock you into a forced maintenance retainer. If you decide next year to hire a local Sylhet developer in-house to maintain it, they have everything they need on day one and nothing is held hostage — which matters even more when the owner is abroad and can't afford to depend on one person's goodwill.
