Take a look at our Case Studies
We are proud of what we have built. Let us walk you through our projects.
How We Build Your Web App
From requirements to launch — a structured process that keeps you informed at every step.
Requirement Gathering
Our business analyst begins a thorough understanding of the project after an NDA is signed and finalized with the client. We prepare a detailed user journey for giving further recommendations.
Design Prototype and User Testing
We initiate the process by designing a clickable prototype which takes around 40 to 80 hours. Once we complete successful user testing, we send you a development quote.
Agile Development
For swift processing, our coordinator makes sprint goals. Only when you confirm the goals. We start the development. You will be continuously informed about the progress through weekly calls by our project coordinator.
Launch and Support
Once we make a beta launch of the app, we monitor its functioning. If the progress persists, we launch it officially. For the next 6 months, we provide free maintenance services for function monitoring.
Why Companies Choose Tech Exactly for Custom Web App Development
Full-stack, in-house team. SaaS and enterprise expertise. Production-grade infrastructure from day one. No subcontracting, no lock-in.
Full-Stack, In-House Team
Frontend, backend, database, DevOps, and QA — all in-house. No subcontracting. You get a single team that owns the entire stack, which means fewer handoff errors, faster debugging, and consistent code quality.
SaaS Architecture Expertise
We've built multi-tenant SaaS platforms from scratch — subscription billing, tenant isolation, feature flags, usage metering, and auto-scaling infrastructure. If you're building a SaaS product, our team knows the architectural patterns that make or break your platform at scale.
Enterprise Integration Experience
We've connected web applications to SAP, Salesforce, Oracle, HubSpot, and custom ERPs. Enterprise web application development isn't just about the app — it's about making it work within your existing infrastructure. We handle SSO (Okta, Azure AD), RBAC, audit logging, and compliance requirements.
Production-Grade from Day 1
Every web app ships with CI/CD pipelines, automated testing, monitoring, and alerting — not just code. We set up the infrastructure that lets your app run reliably at scale, not just the features that let you demo it.
Transparent Pricing, Full Code Ownership
You own 100% of the code, infrastructure configuration, and documentation. Full GitHub repo access from day one. No proprietary frameworks, no lock-in, no "platform fees" after launch.

I’m most impressed with Tech Exactly’s ability to understand our challenges and come up with options to resolve them
Tech Exactly takes the time to listen to us and offers us 3–5 different options to achieve the expected results.
With other vendors I’ve worked with, I have to spend a lot of time explaining the challenge to them, and sometimes, they still don’t understand it.

Frequently Asked Questions
Custom web app development services involve designing, building, and deploying web-based applications tailored to a business's specific workflows, data models, and user needs. Unlike off-the-shelf software (Salesforce, Shopify, WordPress), custom web apps are built from scratch to solve problems that existing tools can't address — complex business logic, unique data relationships, specific compliance requirements, or integrations with internal systems. Our custom web app development services cover the full lifecycle: discovery, UI/UX design, frontend and backend development, QA testing, deployment, and ongoing maintenance.
Custom web app development costs between $20,000 and $200,000+ depending on the app type and complexity. A simple MVP with 5-10 screens costs $20K-$40K and takes 6-10 weeks. A SaaS platform MVP with multi-tenancy and billing costs $40K-$80K and takes 10-16 weeks. A full enterprise web application with integrations (ERP, CRM, SSO) costs $60K-$150K and takes 12-24 weeks. The main cost drivers are number of user roles, integration complexity, compliance requirements, and design complexity.
SaaS application development is the process of building cloud-based software that users access through a web browser on a subscription basis. A SaaS application typically includes multi-tenant architecture (multiple customers sharing infrastructure), subscription billing (monthly/annual), user authentication with role-based access, and an admin dashboard. To develop a SaaS application, you start with market validation and MVP scoping, then build the core platform with multi-tenancy, integrate billing (Stripe, Chargebee), set up authentication and access control, and deploy on cloud infrastructure (AWS, Azure) with auto-scaling.
Progressive web app (PWA) development builds web applications that behave like native mobile apps — with offline support, push notifications, and home screen installation — but run in the browser without requiring app store submission. Choose a PWA when: (1) you want mobile reach without maintaining separate iOS and Android apps, (2) your users are in areas with unreliable internet connectivity, (3) your app is content-heavy, dashboard-based, or e-commerce focused, (4) you want faster time to market at 40-60% lower cost than native. Don't choose a PWA if you need deep hardware access (BLE, NFC on iOS), heavy 3D graphics, or medical device integration.
Enterprise web application development builds web-based software for organizations that need to connect multiple systems, handle complex user permissions, and meet compliance standards (SOC 2, HIPAA, GDPR). Enterprise web apps typically replace manual processes and legacy systems — examples include operations dashboards, customer portals, workflow automation tools, and business intelligence platforms. Enterprise web application development differs from standard web app development in three ways: (1) integration complexity — connecting to ERP, CRM, and internal systems, (2) security and compliance — SSO, RBAC, audit trails, and (3) scale — handling thousands of concurrent users with high availability.
A simple web application MVP takes 6-10 weeks. A SaaS platform MVP takes 10-16 weeks. A full-featured enterprise web application takes 12-24 weeks. A progressive web app takes 6-12 weeks. The timeline depends on feature scope, number of integrations, design complexity, and compliance requirements. We recommend starting with an MVP — launch the core functionality, get real user feedback, then iterate. This approach typically costs 40-60% less than building the "full vision" upfront.
We build five main types of web applications: (1) SaaS platforms — multi-tenant cloud software with subscription billing, (2) Enterprise web applications — internal tools, dashboards, and workflow automation connecting to existing systems, (3) Progressive web apps (PWAs) — browser-based apps with offline support and native-like experience, (4) E-commerce web apps — custom storefronts, marketplaces, and B2B trade portals, (5) Custom business applications — purpose-built tools for specific workflows, data management, and process automation.
Yes. We offer three post-launch support models: (1) Monthly retainer — fixed hours per month for maintenance, bug fixes, and small feature additions, (2) Dedicated team — a full-time team for continuous product development, (3) On-demand support — ad-hoc engagement for urgent issues. All support includes uptime monitoring, security patching, dependency updates, database optimization, and performance monitoring. We also provide a full handoff option — complete documentation, code walkthrough, and knowledge transfer — if you prefer to bring maintenance in-house.
