Your registers are full, Excel sheets disagree with each other, and you pay for three subscriptions that each do half the job. Should you build a custom web app – or buy off the shelf? This decision guide gives Indian SMEs the honest math: when custom wins, when it loses, what each path really costs, and the discovery questions that prevent expensive mistakes.
See our build service: web application development. For simpler needs, a WordPress site may be enough – see website cost guide.
Should I build custom or buy off-the-shelf software?
Buy off-the-shelf when your process is standard (billing, basic CRM, standard appointments) and a mature product with GST and UPI support exists. Build custom when your workflow is your advantage – multi-branch pricing, dealer margins, kitchen-to-delivery tracking, compliance registers no product handles – or when subscription and staff-workaround costs over two years exceed the build cost. The test: if you must change how your business runs to fit the software, price the custom alternative before signing.
What does off-the-shelf really cost?
Count per-user per-month fees times staff times 24 months, plus setup, data migration, training, and the add-ons that make the base plan usable (SMS packs, WhatsApp connectors, extra branches). A “Rs. 999 per month” tool for 8 staff with two add-ons crosses Rs. 3 lakh in two years – before the Excel workarounds it still requires. Cheap subscriptions compound; do the 24-month math on paper before comparing with a build quote.
What does a custom web app really cost?
Custom apps for SMEs typically start around Rs. 80,000 for a focused tool (one workflow, few roles) and rise with branches, roles, reports, integrations (UPI, SMS, WhatsApp API, Tally) and mobile needs. What drives cost is not screens but decisions: approval flows, margin rules, audit trails, offline behaviour. A fixed quote without a discovery mapping of your process is a guess – insist on it. Our scoping covers process mapping first; see how we build.
Who owns the data and code?
In a custom build, your contract should state: you own the code, database and documentation; it runs on your hosting account; you get admin access and source handover; and support terms after launch (response time, what is bug-fix versus new feature). With subscriptions, assume your data exports partially – test the export before you commit 2 years of records to any platform.
What are red flags in app quotes?
- No discovery phase – quote given in one meeting for a “complete ERP”.
- No mention of GST, UPI, roles, backups or who owns code.
- “Unlimited changes” promised with no change-request process.
- No staging demo milestones – big-bang delivery after 4 months.
- Maintenance undefined: who fixes bugs in month 7, and at what cost?
FAQs
How long does a small custom app take? A focused tool: 6 to 10 weeks including testing. Multi-branch systems: 3 to 6 months in phases. Anything promised in 10 days is a template with your logo.
Web app or mobile app? Start with a mobile-friendly web app – one build serves phones, tablets and desktops, and updates deploy instantly. Build a native mobile app only when you need offline-first field use or app-store presence.
