Apps for Chattogram
In Chittagong, the app usually serves the trade, not the shopper
A large share of searches for the best app developer in Chittagong come from businesses that sell to other businesses. Distributors supplying shops across Chattogram, Feni and Cox's Bazar, import traders in Khatunganj and suppliers to the EPZ factories all run on phone orders, credit balances and sales reps carrying paper order books. Those are the processes an app replaces.
For that kind of company, version one is rarely a shopping app. It is a field app for sales reps to take orders at the counter, check stock and record collections, plus a simple ordering app for regular retailers. Loyalty points and consumer features can come later, once the core order flow runs inside the app.
As a mobile app developer in Chittagong, I build for Android first, because field staff and small retailers mostly carry budget Android phones. iOS ships from the same Flutter or React Native codebase when owners or customers need it. Sales rep apps also get offline mode, so an order taken in a weak-signal market in Sitakunda syncs once the phone reconnects.
I work with businesses in Chittagong by phone, email and video, and I do the work myself: no account managers, juniors or outsourcing. That matters on a trade app, where one misunderstanding about credit terms breaks the ledger. You approve the design before any code is written, then pay 50% to start and the remaining 50% at launch.
What's included
What a Chittagong app build includes
Each of these is listed line by line in your quote, so the scope is fixed before the first payment.
01
Sales rep app
Reps take orders, check live stock and log cash or bKash collections at the shop counter. The office sees each order the moment it syncs.
02
Offline order capture
Orders and collections save on the phone when the signal drops and upload automatically when the connection returns.
03
Credit and dues tracking
Each retailer's credit limit, outstanding dues and payment history sit inside the app, so reps stop guessing who has paid.
04
bKash, Nagad and card
Retail customers can pay in the app by bKash, Nagad or card, and every payment is matched to an order in your admin panel.
05
Owner admin panel
A web dashboard shows orders, collections and rep activity by area, from Agrabad to Halishahar, without anyone sending you a report.
06
Both stores, one codebase
If you were looking for the best iOS app developer in Chittagong as well as Android, both apps ship from one Flutter or React Native codebase, which keeps every update cheaper.
In focus
What drives app cost in Chittagong, and how to keep it down
The biggest cost driver is not the screens. It is the business rules behind them: credit limits, distributor price tiers, returns and partial deliveries all need logic and testing. Write down how your team handles each of these today, even on paper, and bring it to the scoping call. A clear process makes the quote smaller and far more accurate.
The second driver is the number of user types. A rep app, a retailer app and an admin panel are three products sharing one backend. If you want an affordable app developer in Chattogram, phasing is how you get there: launch the rep app and admin panel first, then add retailer self-ordering once the data has proved clean.
Finally, compare quotes on what they include, whether they come from an agency or a freelance mobile app developer in Chittagong. Ask whether Play Store and App Store publishing, payment gateway setup, the admin panel and post-launch fixes are written in. Custom builds with me start from ৳3,00,000, and every one of those items appears in writing before you pay anything.

Before you hire
How to choose the best app developer in Chittagong
Before paying a deposit, put any app developer in Chittagong or wider Chattogram through these six practical tests built around trade and field sales.
01
Run an airplane mode test
Ask for a demo build, switch the phone to airplane mode, take an order, then reconnect. If the order disappears or appears twice, the app will fail your reps in weak-signal markets.
02
Walk through a credit sale
Describe a real credit sale to a Chattogram retailer and ask how the app records the limit, the due date and a partial payment. Vague answers mean the ledger logic has not been planned.
03
Ask which phones are supported
Ask which Android versions and handset models the app will be tested on. Your reps and retailers carry budget phones, so a developer who only tests on new flagships is a risk.
04
Check data export rights
Ask where order and retailer data will be stored, who can export it, and how you get a full copy if you change developers. You want that answer in writing before you sign.
05
Test Bangla and English search
Ask whether reps can type shop names in Bangla or English and still find them in search. Mixed-language records are normal in Khatunganj trade and quickly break poorly built apps.
06
Ask how sync conflicts resolve
Ask what happens when two reps update the same retailer's order or stock at the same moment. A capable developer explains which change wins and how the office is alerted.
Frequently asked
Straight answers before you hire.
Answers to the questions Chittagong owners ask most before starting an app.
How much does an app developer in Chittagong charge for a custom app?
My custom builds start from ৳3,00,000. The exact price comes in writing after a free scoping call, with 50% paid to start and 50% at launch by bKash, Nagad, bank transfer or card. You approve the design before development begins and get a demo of the working app every week.
When will my app be ready to launch?
The launch date goes into the written quote once the scoping call has fixed the feature list. A rep app with an admin panel is a far smaller build than a multi-role marketplace, so phasing the work is the quickest way to get something live. Weekly demos show exactly where the build stands.
What should I look for in the best app developer in Chittagong?
Look for someone who asks about your credit terms, delivery routes and payment habits before talking about screens. Then check that the quote names every deliverable and that you will speak to the person writing the code. My record is 120+ projects for 50+ clients and teams, with a 4.9 average rating.
What does the build include?
Screen design you approve first, Android and iOS apps from one codebase, an admin panel, bKash, Nagad or card payment setup, testing on budget Android phones, then launch, QA and handover. Monthly support after launch is optional and quoted as a fixed fee in writing.
Do you visit offices in Agrabad, or is the work done remotely?
I work with Chattogram businesses by phone, email and video call rather than office visits. The free 15-minute call, the design review and every weekly demo happen online, and test builds install straight onto your phone so you can try them in the shop or the warehouse.
Can the app keep working where mobile signal is weak?
Yes, and any Android app developer in Chattogram should plan for it. Field and sales rep apps are built with offline mode, so orders, photos and collections save on the phone and sync when the connection returns. This is planned into the scope on the first call, because adding offline support after launch costs more than building it in from the start.
Who is the best app developer in Chittagong?
No single app developer in Chittagong is best for every business; the right pick depends on your goal and your budget. For trade and field apps in Chattogram, three criteria matter most: offline order capture, correct credit and dues logic, and direct contact with the person writing the code. RH Fardin fits owners who want one senior developer for the whole build, with 120+ projects delivered, a 4.9 average rating and custom builds from ৳3,00,000.
What should I prepare before the first call with an app developer in Chittagong?
Write down who will use the app (owners, sales reps, retailers or end customers), how an order moves from the shop counter to delivery today, and how credit and collections are recorded. Photos of a paper order book or khata page help a lot. With that in hand, RH Fardin can use the free 15-minute call to shape a first version for your Chattogram business.
