Web Application Development Services

Custom Web Apps Built in Your Own Cloud

You get browser-based software built around your work: internal tools, portals linked to your customer relationship management (CRM) or enterprise resource planning (ERP) system, and the application programming interfaces (APIs) behind them. Engineers and a quality assurance (QA) lead deploy each application in your cloud. Every step has a fixed price, and working screens reach staging every two weeks.

Each step ends with a decision, and none commits you further. We start where your staff or customers lose the most time today. We map that workflow’s users, screens, data and connected systems, scope the smallest release that fixes it, and price each route 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 no build is worth it, the verdict tells you.

What do web application services include?

Web application development is the work of designing, building, testing and running software that people use in a web browser. Our web application development services cover user experience (UX) and screen design, the data model and APIs, the front end and back end, automated tests, deployment to your cloud and the maintenance after launch.

  • Built and deployed in your cloud accounts, under your domains.
  • Source code, infrastructure and documentation assigned to you from the first commit.
  • Browser-based applications only; native mobile apps are out of scope.
  • Every change reviewed by a second engineer and covered by automated tests.
  • Personal data handled only under a signed data processing agreement.

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

Security patches, dependency updates, monitoring, fixes and small features each month, handled by a named engineer who knows the application. Outdated components ranked second in the OWASP Top 10:2021 community survey, with over 30,000 occurrences.

Modernising an existing web app

The web application you already run, refactored and moved to current frameworks in stages, with users working on it the whole time.

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 you also build software products?

Yes: web application development services cover software products too, the web applications your customers pay for. We take a product from discovery and a minimum viable product (MVP) your first users can log into, through 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 make up a customer portal?

Web application development services build a customer portal in five layers. People log in, use the screens, and reach data through APIs and a back end that enforce roles and permissions. Below that sit the data model and the links to your CRM and payment gateway. The pilot below shows each layer checked; yellow marks where a person signs.

According to the National Institute of Standards and Technology (NIST) glossary, role-based access control is “Access control based on user roles (i.e., a collection of access authorizations that a user receives based on an explicit or implicit assumption of a given role).” In a customer portal, those roles decide which orders, cases and invoices each person sees. Broken access control ranks first in the OWASP Top 10:2021, with over 318,000 recorded occurrences.

Illustrative example. A person signs at each yellow mark, and every item can be followed back to its story, commit and test.

How does the five-step process work?

Our web application development services follow five steps. After a free scoping call, a two-week diagnostic maps users, screens, data and systems and quotes the pilot. The six-to-eight-week pilot then puts one workflow live. Production arrives in staged releases with integrations and training, and Managed Ops comes last. You can stop after any written result.

Which type of web application do you need?

A tool for your own staff is an internal application, and something customers log into is a portal. Something customers pay for is a software product, and a web app you already run needs modernisation. Several departments on one data model need an enterprise system, part of our custom software development. Five questions show which one fits.

Question Internal web application Customer or partner portal Software product Modernisation
Who logs in Your staff Your customers or partners Paying subscribers The users you already have
What it replaces Spreadsheets or an off-the-shelf tool Requests handled by your staff Nothing yet, or a competitor’s product The web application you already run
Who pays to use it Nobody; internal cost Nobody; part of your service Subscribers, from the first release Nobody; protects what you have
First release One workflow, end to end Login, one record type and one integration Accounts, billing and the core workflow One module refactored, users unaffected
Where it starts Scoping call Scoping call Discovery Diagnostic

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?

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.

Book a Diagnostic

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 app partner?

A web application development company proves itself with applications that clients still use two years after launch, not with headcount. We ship custom web applications in staged releases, priced in writing and hosted in your cloud. Every build gets code review and automated tests, and personal data falls 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
  • Source code stuck in the vendor’s repository once the contract ends

Is it safe to outsource web application development?

Outsourcing web application development offshore is safe once ownership, access and personal data are covered by signed terms before the first commit. As a Bangladesh-based company, we work in your repositories and cloud with least-privilege access. Intellectual property (IP) is assigned to you, and credentials come back at handover. Reviewed By Eicra.com team

The Open Worldwide Application Security Project (OWASP) states that its Top 10 is “a standard awareness document for developers and web application security”. We run those Top 10 checks before every production release.

Which agreements are signed, and when?

Non-disclosure agreement (NDA) — mutual, and signed before any requirement, login or line of code changes hands.
Data processing agreement (DPA) — Article 28(3) GDPR processor terms, plus the matching national law, for personal data in any environment.
International data transfers — signed standard contractual clauses, or the instrument your jurisdiction demands, before personal data crosses a border.
Access — each engineer gets the least privilege needed in your repositories and cloud; production credentials never leave your vault.
Certifications — none are claimed here or in proposals; one is listed only after it is held.

What controls, IP and rework terms apply?

Your accounts Repositories, pipelines, environments and domains open under your accounts on day one; we keep no hosting of our own.
Code ownership The contract hands you every right in the code; third-party licences are listed, and copyleft needs your written sign-off.
Reviews Each change needs a pull request, passing automated tests and another engineer’s approval before it lands on 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 Fixes cost nothing when a release misses its agreed acceptance tests; extra scope is priced as a change request first.

What proof do you get before you pay?

Before you pay for web application development, you can click through it. The three measured commitments below apply to every project, and the pilot puts one working workflow live before production is quoted. The first scoping call is free and lasts 30 minutes.

2 weeks

Between demos of working screens on staging, from engineers, a QA lead and a project manager, not slides.

6–8 weeks

From pilot start to the first tested, deployed release your users can log into.

30 days

Of free fixes following each release to production, with documentation and training for whoever runs the application.

Case studies: named client results will be added as each client gives consent. Ask for references from your sector on the scoping call.

What do buyers ask about web application development?

Buyers ask a web application development company ten questions before they sign: cost, timeline, ownership, what happens after an enquiry, where data lives, how confidentiality holds, and what is out of scope. Each answer below follows the prices, steps and terms on this page.

What will a web application project cost?

Web application development with us is priced by result, never by the hour. The price cards at the top list each step: a two-week diagnostic that is half credited to the pilot, a fixed-price pilot for one workflow or portal, and production quoted in writing.

What does a web app development company do?

A web app development company designs, codes and tests browser-based software that fits one business. It maps the workflow and the systems around it, designs the screens and data model, writes the front end, back end and APIs, then deploys to your cloud and keeps it running.

Web application or website, what differs?

A website publishes the same pages to everyone; a web application is software people log into, with accounts, roles, data they create and change, and links to other systems. We build web applications only; marketing sites, brand design and content belong with a web design agency.

How long does a web application take?

Eight to ten weeks to a first release: two weeks of diagnostic, then a six-to-eight-week pilot that puts one workflow or portal live. Production then adds eight to sixteen weeks, depending on screens, roles and integrations, released in stages people use as they land.

Who owns your code and your data?

You do. The code sits in your repositories, the application runs in your cloud accounts, and the contract records your ownership from the first commit. Our team reaches your data only through least-privilege access, under a signed data processing agreement, and loses that access at handover.

What happens after I send an enquiry?

You get a reply proposing times for the free scoping call; nothing starts until you confirm in writing:

  1. On the call we discuss the workflow that costs you most.
  2. If a diagnostic fits, you receive a written quote.
  3. You decide; no engineer touches your systems before that.

Can you take over a half-built app?

Yes, if we can read the code and the repository history. The diagnostic opens with a code and infrastructure review, written up as findings you own. You then choose: continue on the existing stack, refactor in stages, or rebuild one module at a time.

Where is our data stored and processed?

In your own cloud accounts and regions; we hold no copy, and engineer access ends at handover. Bangladesh has no European Union adequacy decision, so for EU personal data we sign standard contractual clauses and complete the required transfer impact assessment before any access.

How is confidentiality protected?

Through a mutual non-disclosure agreement signed before any requirement, login or code changes hands, then least-privilege access. Each engineer sees only what their work needs, production credentials stay in your vault, and access is revoked at handover. Your requirements and designs stay confidential.

What do you not build?

Native iOS and Android apps, marketing websites, brand design and content. We build browser-based applications only: internal tools, portals, dashboards, software products and the APIs behind them. If your project is mostly a mobile app or a brochure site, we say so on the scoping call.

Start with a free 30-minute scoping call or the two-week diagnostic.
