Offline-first field apps
Apps that keep working in a basement, a village or a lift: a local database on the device, a queue of changes, and clear rules for what happens when two edits conflict.

How do I hire Flutter developers in Bangladesh?
Hiring flutter developers through BetterSoftZ means engaging engineers employed in Dhaka who work exclusively on your product on a monthly agreement. They work in your repository and sprint process, you meet them before the engagement starts, and all code and infrastructure remain yours.
What we put them on.
- Field and delivery apps that must work offline
- Customer apps with mobile financial services payments
- Internal apps for shared devices on a factory floor
- One codebase covering Android and iOS
What do Flutter developers usually build?
Customer apps with mobile payments
Ordering, booking or account apps that take payment through mobile financial services, with the payment state handled carefully when the connection drops mid-transaction.
Scanning and check-in apps
Apps that scan codes at a gate or desk. We have built an offline-capable scanner for race-day kit collection at Northern Marathon 2026; whether Flutter is the right fit for a given scanner depends on the devices and hardware involved.
Android and iOS releases
One codebase for both platforms, plus the unglamorous work of store listings, signing, test builds and review feedback.
What does a typical team look like?
Mobile work usually starts with one or two Flutter engineers and a back-end engineer, either from your side or ours, because most apps are only as good as the API behind them. A QA engineer helps most near release, when testing on real devices matters.
What should you check in an interview?
- Ask how they would design sync and conflict handling for an app used offline for hours.
- Ask which devices they test on, including older and low-memory Android phones.
- Ask how they structure state in a large app, and why they chose that approach.
- Ask about their last store release and what the review process changed.
Where this stack is the wrong choice.
Where an app leans heavily on platform-specific hardware or background behaviour, native code earns its extra cost and we will recommend it.
How does the engagement work?
Hiring developers here normally means the dedicated team model: a named squad works only on your product for a monthly fee, and you decide scope sprint by sprint. There is a three-month minimum, then it runs month to month. Two other models exist, and the right one depends on how settled the work is.
Dedicated team
Best when the roadmap runs past one release and priorities shift. This is what hiring developers usually means.
Fixed price
Better when you can specify the whole project up front and want one figure with milestone payments, rather than engineers by the month.
Time and materials
Suits discovery, audits and support, billed against time worked with a cap agreed in advance.
Under every model, source code and infrastructure accounts are yours, you get working software on a staging link every two weeks, and you get written progress notes each week.
How does onboarding work?
- 1
Brief
You describe the work, the roadmap and how your sprints run. We propose a squad shape that fits, not a standard package.
- 2
Meet the engineers
You see CVs, then speak to the people proposed. If someone is not right, we propose another rather than defend the first choice.
- 3
Access
Each engineer gets a named account in your repository, tracker and chat, in accounts you own. We suggest giving only the access the work needs.
- 4
A small first task
We suggest the first task is small but real: a change that goes through your whole pipeline to staging, so any friction in the process shows up before large work begins.
- 5
Steady rhythm
Regular sprints, written weekly notes, and a notice period and handover plan that were agreed in the contract before anyone started.
How much do working hours overlap with ours?
Dhaka is GMT+6 and Bangladesh does not currently use daylight saving, so the offset only moves when your clocks do. That makes the overlap simple arithmetic. Dhaka is 6 hours ahead of the UK in winter and 5 in summer, so a morning in the UK is already afternoon in Dhaka. It is 10 to 11 hours ahead of US Eastern time, so overlap with the US is the end of the Dhaka day. Australia is 4 to 5 hours ahead of Dhaka, which leaves a large shared window.
We recommend agreeing a core overlap window in writing at the start, for stand-ups and reviews, and letting everything else run asynchronously through the tracker and written notes. Tell us your hours in the brief and we will say plainly how much overlap that gives you.
Engagement
Common questions
Whose name should the app store accounts be in?
Yours. We recommend that the Apple and Google developer accounts belong to your organisation, with our engineers added as team members, which matches how infrastructure and code stay yours under every engagement model.
Will the app run on cheap or older Android phones?
It can, if it is tested on them. We recommend agreeing a list of target devices at the start, based on what your users actually carry, and testing against that list rather than only on new phones.
Can the Flutter app use a back end we already have?
Yes. Flutter engineers work against an existing Laravel, Node or .NET API. If the API was not designed for mobile, for example no pagination or poor error responses, we say so early and propose the changes it needs.
How quickly can flutter developers start?
Typically two to three weeks from agreement, depending on the seniority mix. We would rather propose a start date we can hold than promise next Monday and put whoever happens to be free on your product.
Can we interview the engineers first?
Yes, and we recommend it. You see CVs, then speak to the people proposed. If someone is not right for your team, we propose someone else rather than pushing the original choice.
What if we need to scale the team up or down?
Scaling up takes a few weeks for the right person. Scaling down follows the notice period in the agreement. Neither requires renegotiating the whole contract.
What does it cost?
A monthly rate per engineer, set by seniority and agreed before start, with no separate recruitment or onboarding fee. We quote after understanding the work, because a team shape proposed without that is guesswork.
Who manages the engineers day to day?
You do. You set priorities, review the work and run the sprint. The engineers are employed by BetterSoftZ in Dhaka, and the agreement sets out how a handover works if someone leaves or must be replaced.
Who owns the code and the accounts?
You do. Source code and work product belong to you on payment, and repositories, hosting and third-party services run in accounts you own, so you never depend on us to reach your own system.
Tell us what the team needs to cover.
We will propose a squad shape, name the engineers, and set a start date we can actually hold.
