Application Development
Web application development services build the browser-based software your business runs on: internal tools that replace spreadsheets, customer portals that connect to your customer relationship management (CRM) or enterprise resource planning (ERP) system, dashboards and the application programming interfaces (APIs) behind them. As a Dhaka-based company, we design, build, test and deploy each application inside your own cloud, for international companies, at a fixed price per step, with engineers, a quality assurance (QA) lead and a project manager who put working screens on staging every two weeks, not slides.
One exit at each step. No long-term commitment at any of them. We start with the one workflow that costs your staff or your customers the most time today. Its users, screens, data and connected systems are mapped, the smallest release that removes the pain is defined, and every route to it is costed in your own numbers.
You get a written verdict — an internal web application, piloted first; a customer portal; a product build; a modernisation of the web app you already run; or nothing yet. If nothing justifies a build, you stop here.

What is included in web application development services?
Web application development services design, build, test and maintain browser-based software that people log into: user experience (UX) and screen design, the data model and APIs, the front end and back end, automated testing, deployment to your cloud, and the maintenance that follows. Each card below is one kind of application or service we build.
Internal tools and workflow apps
Approvals, requests, scheduling and back-office workflows that replace spreadsheets and email chains, with roles, audit trails and exports your teams already expect.
Customer and partner portals
Self-service portals where customers or partners log in to see orders, cases, invoices and documents, connected to the CRM or ERP you already run.
Dashboards and admin panels
Operational dashboards and back-office consoles over your live data, with filters, drill-downs, role-based views and scheduled exports, built for daily use.
APIs and integrations
Representational state transfer (REST) or GraphQL APIs and connectors between your web application, CRM, ERP and payment systems, with data contracts written down, versioned and tested.
Application maintenance and support
Fixes, small features, monitoring, security patches and dependency updates on a monthly plan, with a named engineer who knows the code.
Modernising an existing web app
The web application you already run, refactored, migrated to current frameworks and reconnected in stages, so nothing stops while it improves.
Not included: Native iOS and Android apps · marketing websites, brand design and content · new scope outside the agreed release, priced first as a change request.
Do web application development services also cover software products?
Yes: web application development services cover software products too, the web applications your customers pay for, from discovery and a minimum viable product (MVP) your first users can log into to the release process and the lifecycle engineering that follows. A product differs from an internal tool: accounts, billing and a roadmap from day one.
Discovery
Users, competitors, pricing and the first release defined in two weeks, with the MVP quoted in writing.
MVP
The smallest version paying users can log into: accounts, billing, the core workflow, tested and deployed.
Release
A release process with staging, automated tests, monitoring and a rollback path, so every version ships safely.
Lifecycle engineering
The roadmap after launch: features from user feedback, scaling, security updates and a named team that stays.
Which layers do web application development services build into a customer portal?
Web application development services build a customer portal in five layers: the people who log in, the screens they use, the APIs and back end that enforce roles and permissions, the data model, and the connections to your CRM and payment gateway. The sample pilot below shows how each layer is checked; yellow marks where a person signs.

How do web application development services work, from scope to Managed Ops?
Web application development services with us run in five steps: a free scoping call, a two-week diagnostic that maps users, screens, data and systems and quotes the pilot, a six-to-eight-week pilot that ships one workflow end to end, production in staged releases with integrations and training, then Managed Ops. Every step ends with a written result you can stop on.

Scope A call about the workflow that hurts most and the systems around it. If users and sources are known, you leave with a diagnostic quote.
02 2 weeks · credited
Diagnose Users, screens, data and connected systems mapped; the smallest useful release defined; architecture and stack chosen for your cloud; the pilot priced in writing.
03 6–8 weeks · fixed price
Pilot One workflow built end to end: screens, data model, one integration, automated tests, staging and production deploy, and a demo every two weeks.
04 Staged · quoted after pilot
Production The remaining screens, roles and integrations in releases people start using early, plus documentation, team training and 30 days of fixes after each release.
05 Monthly · optional
Managed Ops Fixes, small features, monitoring, security patches and dependency updates, with a named engineer and a monthly review call. Cancel any month; everything stays yours.
Who builds your web application, and with what?
A named team you meet on the first call: engineers for the front end, back end and APIs, a QA lead who owns tests and release sign-off, and a project manager who runs the demos.
Communication Demo every two weeks, shared channel, written change log
Delivery Git repositories, continuous integration pipeline, staging and production
QA Automated tests, manual test rounds, user acceptance testing (UAT) before release
Hosting Your cloud accounts, your domains, your credentials

Which web application do you need: an internal tool, a portal, a product or a modernisation?
Web application development services are not one build: a tool for your own staff is an internal application; something your customers log into is a portal; something customers pay for is a software product; a web app you already run is a modernisation; several departments on one data model is an enterprise web application. Five questions show which one fits.
1. Who will log in?
2. What does it replace?
3. Will people pay to use it?
4. How many systems must it connect to?
5. When must the first release be live?
Which one do you need? Answer five questions.
An internal web application, piloted first
One or two workflows for your own staff, replacing spreadsheets or an off-the-shelf tool: a pilot ships the first workflow end to end in six to eight weeks.
A first estimate; the diagnostic confirms it.
How the verdict is decided
A web app you already run → modernise what you have
Paying subscribers, or people will pay to use it → a software product build
Customers or partners log in → a portal
Everything else → an internal web application, piloted first
Why choose us as your web application development company?
A web application development company is judged on the applications its clients still run two years later, not on its headcount. We deliver custom web application development in staged releases, priced in writing, in your cloud: code review and automated tests in every build, and personal data handled under Article 28 of the General Data Protection Regulation (GDPR).
Without a staged process
!!!!!
- A design mock-up signed off, then screens that behave differently
- A demo at the end that nobody has used before the invoice
- Hourly billing that grows as the scope outgrows the pitch
- Code in the vendor’s repository you cannot reach after the contract

Is it safe to outsource web application development?
Outsourcing web application development offshore is safe when ownership, access and data handling are settled in writing before the first commit. As a Bangladesh-based company, we work in your repositories and cloud with least-privilege access, assign intellectual property (IP) to you, sign a data processing agreement before touching personal data, and return credentials at handover. Reviewed By Eicra.com team
Which web application agreements are signed, and when?
Non-disclosure agreement (NDA) — mutual, signed before any requirement, credential or code is shared with anyone.
Data processing agreement (DPA) — processor terms under Article 28(3) of the GDPR and the equivalent national law, for any personal data in test or production.
International data transfers — standard contractual clauses or the transfer instrument your jurisdiction requires, signed before personal data moves.
Access — least-privilege roles in your repositories and cloud; production credentials stay in your vault, never in ours.
Certifications — listed only when held; none are claimed on this page or in any proposal.
What web application controls, IP and rework terms apply?
Your accounts Code, pipelines, environments and domains are created in your accounts from day one; nothing is hosted on our side.
Code ownership All intellectual property is assigned to you in the contract; third-party licences are listed, and none are copyleft without your sign-off.
Reviews Every change goes through a pull request, an automated test run and a second engineer’s review before it reaches staging.
Security testing Dependency scans and Open Worldwide Application Security Project (OWASP) Top 10 checks run before every production release; findings are fixed or accepted in writing.
Rework Free when a release fails its agreed acceptance tests; new scope is priced first as a change request.
What proof do you get before you pay for web application development?
Before you pay for web application development, you get evidence instead of promises: measured commitments, a pilot that ships one working workflow before production is quoted, and a free 30-minute scoping call. Client case studies with numbers are added here as clients give permission to name them.
2 weeks
Between demos of working screens on staging, from engineers, a QA lead and a project manager, not slides.
6–8 weeks
From the start of the pilot to a first release your users log into, tested and deployed.
30 days
Of fixes after each production release, plus documentation and team training for the people who will run the application.
Case studies: client results with numbers are added here as clients give permission to name them. Ask on the scoping call for references in your industry.
What do buyers ask about web application development?
How much do web application development services cost?
Our web application development services are priced per outcome, not per hour, and each price is on the price cards at the top: a two-week diagnostic ending in a written verdict and a pilot quote, half credited to the pilot; a six-to-eight-week pilot that puts one workflow or portal live, tested and deployed; then production, quoted in writing.
What does a web app development company do?
A web app development company builds browser-based software your business cannot buy off the shelf: it maps the workflow and the systems around it, designs the screens and data model, writes the front end, back end and APIs, tests them and deploys to your cloud. The good ones show working screens every two weeks and hand over code you own.
What is the difference between a website and a web application?
A website publishes pages that everyone sees the same way; a web application is software people log into, with accounts, roles, data they create and change, and connections to other systems. We build web applications. Marketing sites, brand design and content are not part of this service; a web design agency does that work.
How long does it take to build a web application?
A first release takes eight to ten weeks: a two-week diagnostic, then a six-to-eight-week pilot that ships one workflow or one portal end to end, tested and deployed. Production adds eight to sixteen weeks depending on the number of screens, roles and integrations, released in stages so people start using the application before the last stage is built.
Who owns the code, the data and the infrastructure?
You do. Code lives in your repositories, the application runs in your cloud accounts, and ownership is written into the contract from the first commit. Your data never leaves your systems; our offshore team works through least-privilege access, signs a data processing agreement before any personal data is touched, and is removed at handover.
