How Much Does Custom Web App Development Cost in India? (2026 Guide)

What drives the cost of a custom web application

Custom web application cost is driven by four variables: the number of distinct user roles and their permission structures, the complexity of the data model, the number and depth of third-party integrations, and the performance and security requirements. A single-role internal tool with no integrations costs a fraction of a multi-tenant SaaS platform with five external API connections.

Price ranges by project type (2026, India)

• Simple internal tools and dashboards — single user role, basic CRUD operations, minimal integrations: ₹15,000 – ₹40,000. Timeline: 3–5 weeks.
• Mid-complexity business applications — multiple roles with RBAC, 2–4 third-party integrations (Razorpay, WhatsApp API, Tally), reporting module: ₹60,000 – ₹1,80,000. Timeline: 6–10 weeks.
• ERP, CRM and operational platforms — complex data models, multi-department workflows, deep ERP integration (Tally or SAP), audit trails: ₹1,50,000 – ₹4,00,000. Timeline: 10–18 weeks.
• SaaS platforms and marketplaces — multi-tenant architecture, subscription billing (Stripe or Razorpay), admin portal, usage-based metering, onboarding flows: ₹3,00,000 – ₹10,00,000+. Timeline: 16–32 weeks.
• AI-powered applications — LLM integration (OpenAI or Anthropic API), RAG pipelines over private data, agentic workflow layers: add ₹80,000 – ₹2,50,000 to the base project cost depending on scope.

What is included in Marketing Wise's pricing

Every project includes: discovery and requirements mapping, domain-driven data architecture, REST and GraphQL API design, component-level React or Next.js frontend engineering, automated QA (unit and integration tests), staged deployment to AWS or GCP with CI/CD, and a documented handover including full source code, repository access, infrastructure credentials and a production runbook. There are no hidden charges for project management, code reviews, or deployment setup.

What is not included

Third-party API subscription costs (Razorpay processing fees, WhatsApp Business API charges, AWS hosting bills) are not included — these are pass-through costs you pay directly to the vendor. Domain and SSL certificates are your cost. Stock photography or custom illustration, if required, is quoted separately.

Fixed-price vs retainer: which model fits your project

Fixed-price contracts work when the scope is clearly defined upfront. We provide a line-item quote broken down by module — not a vague lump sum — and the final cost does not change unless you add scope. This is the right model for most first builds.

Monthly retainers work for ongoing product development — adding features, responding to user feedback, scaling infrastructure, or running AMC (Annual Maintenance Contract) after launch. Retainers start at ₹20,000/month and are scoped to a defined number of engineering hours per month.

Why Indian agencies vary so widely on price

A freelancer in Tier-2 India will quote ₹8,000 for a project that a boutique agency in Delhi NCR quotes ₹1,20,000 for. The difference is not margin — it is what is actually delivered. Freelancer projects frequently lack: proper database architecture, security implementation (OWASP compliance, encryption at rest), automated testing, deployment pipelines, infrastructure documentation, and ongoing support. The ₹8,000 project becomes a ₹2,50,000 rebuild 18 months later.

Marketing Wise quotes at the level that includes all of the above — because we have been maintaining what we build since 2014, and we know what shortcuts cost the client downstream.
