What We Build

Software Solutions for Every Business Need

From lean startup MVPs to enterprise-scale platforms — we build software that fits your exact requirements, integrates with your existing systems, and grows with your business.
Enterprise ERP Systems

We build fully custom ERP platforms that unify your operations — finance, inventory, HR, procurement and reporting — into a single intelligent system built for Bangladesh businesses.

SaaS Platform Development

From MVP to multi-tenant cloud platforms, we design and build scalable SaaS products with subscription billing, onboarding flows, dashboards, and API-first architecture.

CRM & Customer Platforms

Custom CRM systems that track leads, automate follow-ups, manage pipelines, and integrate with your WhatsApp, email, and SMS channels — built around your sales process.

Mobile App Development

Cross-platform mobile apps (iOS + Android) built with React Native or Flutter — with offline support, push notifications, payment integration, and native performance.

REST APIs & Microservices

Scalable, documented RESTful and GraphQL APIs built on Node.js, Laravel, FastAPI or Spring Boot. Microservices architecture for teams that need independent deployments.

AI-Powered Solutions

Integrate machine learning, LLMs, and automation into your software — from intelligent chatbots and recommendation engines to document processing and predictive analytics.

Our Process

6-Step Development Process

A structured, transparent process built around Agile principles. You always know where your project stands — and why every decision was made.
01
Week 1

Discovery & Analysis

We run structured workshops to document your requirements, map user journeys, identify system boundaries, and define KPIs. Output: detailed specifications and project brief.
02
Week 1–2

Architecture Design

System architecture, database schema, API contracts, and deployment topology are planned before a single line of code is written. Avoids expensive rework later.
03
Week 2–3

UI/UX Prototyping

Figma wireframes and interactive prototypes let you validate flows and branding before development starts. Stakeholder sign-off at this stage keeps scope clean.
04
Weeks 3–N

Agile Development

Two-week sprints with daily standups, bi-weekly demos, and a living backlog you can always see. You have full visibility via Jira — no black boxes.
05
Ongoing

Testing & Security QA

Unit tests, integration tests, performance benchmarking, OWASP security scanning, and cross-device compatibility testing run in every sprint, not just at the end.
06
Launch +

Deployment & Support

We handle CI/CD pipelines, staging and production deployments, SSL, uptime monitoring, and provide 30–90 days of post-launch support included in every engagement.
Why W3 Techniques

What Makes Us Different

Hundreds of agencies build software. Very few build it with the precision, transparency, and long-term reliability that your business deserves.

8+ Years of Software Expertise

Our team has shipped production software since 2016 — from small business tools to multi-tenant SaaS platforms serving thousands of users across Bangladesh and internationally.

True Agile Methodology

Two-week sprints, daily standups, transparent Jira boards, and bi-weekly client demos. You see real progress — not polished presentations designed to delay tough conversations.

100% Source Code Ownership

When the project is complete, you own everything — all source code, databases, documentation, and deployment credentials. No vendor lock-in, ever.

Transparent Project Management

Real-time access to your Jira project, weekly status reports, and direct communication with your lead developer. No middlemen hiding bad news.

Dedicated Post-Launch Support

Every project includes 30–90 days of free post-launch support. Bug fixes, performance tuning, minor enhancements — we stay on until your software is fully stable in production.

Security-First Architecture

OWASP Top 10 mitigations, encrypted data storage, role-based access control, SSL/TLS everywhere, and regular dependency vulnerability audits are standard in every build.

Industries We Serve

Built for Your Industry

Our developers have shipped production software across 8+ verticals. We speak your domain language — not just code.

Healthcare & Telemedicine

Patient portals, appointment systems, EMR/EHR integration, telemedicine platforms, pharmacy management, and HIPAA-aligned data handling.

Finance & Fintech

Banking dashboards, loan management systems, payment gateways (SSLCommerz, bKash, Nagad), digital wallets, and regulatory compliance tools.

Education & E-Learning

LMS platforms, live class systems, student management, certificate generation, AI-powered tutoring tools, and SCORM-compliant course delivery.

Retail & E-Commerce

Custom storefronts, inventory systems, multi-vendor marketplaces, POS integration, loyalty programs, and warehouse management systems.

Manufacturing & ERP

Production planning, BOM management, supply chain tracking, quality control workflows, and real-time factory floor dashboards.

Real Estate & PropTech

Property listing platforms, rental management, broker CRMs, lease tracking, virtual tour integration, and Bangladesh land registry connections.

Logistics & Supply Chain

Fleet tracking, route optimisation, warehouse management, delivery scheduling, driver apps, and last-mile delivery dashboards.

NGO & Government

Beneficiary management, grant tracking, reporting portals, e-service delivery, mobile field apps, and interoperability with government APIs.

Engagement Models

Choose How We Work Together

We adapt to your project and budget — not the other way around. Every model includes full IP ownership, source code delivery, and a signed NDA.
Fixed-Price Project

Best for well-defined projects with a clear scope. You agree on price, timeline, and deliverables upfront. Ideal for MVPs, landing pages, or complete system rebuilds with documented requirements.

Time & Material

Pay for actual hours worked. Perfect for evolving projects where requirements may change. Full transparency via time-tracking reports and bi-weekly invoices. Most popular for SaaS products.

Dedicated Team

Hire a dedicated squad of developers, designers, and QA engineers working exclusively on your product, full-time. Scales up or down monthly. Ideal for ongoing product development.

FAQ

Common Questions Answered

Everything you need to know before starting a custom software project with W3 Techniques.
Custom software development is the process of designing, building, and deploying software applications specifically for your business — rather than using off-the-shelf products like generic accounting software. Custom software fits your exact workflows, integrates with your existing tools, and scales on your terms.
A straightforward web application or MVP typically takes 6–10 weeks. A mid-complexity SaaS platform takes 12–20 weeks. Enterprise ERP or large-scale systems can take 6–12 months. We give you a detailed timeline breakdown during our free discovery call.
We choose the stack that best fits your project’s needs. For web apps we commonly use React/Next.js (frontend), Node.js or Laravel (backend), and PostgreSQL or MongoDB (database). For mobile apps we use React Native or Flutter. For AI integrations we work with Python (FastAPI), OpenAI APIs, and LangChain. We always explain our recommendations before writing a line of code.
Costs depend on scope, complexity, and the engagement model. A basic custom web application starts from BDT 80,000–150,000. A full SaaS platform typically ranges from BDT 300,000–800,000. Enterprise systems are quoted on scope. We offer fixed-price contracts, time & material, and dedicated team models. Contact us for a free quote.
Yes — 100%. You own all source code, database schemas, documentation, design files, and all associated assets. We provide a full code handover in a private Git repository. We also sign an NDA before any work begins. There is no vendor lock-in of any kind.
Absolutely. We integrate with third-party APIs (bKash, Nagad, SSLCommerz, Stripe), existing databases, ERP systems, government APIs, e-commerce platforms, WhatsApp Business API, email providers, and any other system that provides an API or data export. We’ve done hundreds of integrations.
Yes. Every project includes 30–90 days of free post-launch support depending on project size. After that, we offer affordable monthly retainer plans that cover bug fixes, minor updates, security patches, performance monitoring, and on-call support for urgent issues.
Yes. We work with clients across Bangladesh — Chittagong, Sylhet, Rajshahi, Khulna, and all other divisions — as well as internationally. All project management, communication, and deliverables are handled online. We use Slack, Jira, Zoom, and Figma for seamless remote collaboration.
