An honest, no-affiliate comparison from a Pvt Ltd that does both — we build custom software and we configure SaaS tools. With Indian INR pricing, real lock-in considerations, and a single recommendation at the end.
Quick answer: SaaS wins for standard problems where someone has already built a 90%-fit solution — accounting (Tally), email (Google Workspace), payments (Razorpay), generic CRM (Zoho/HubSpot). Custom wins when your workflow is opinionated, when per-user fees compound past ₹3-5L/year, when you need real Indian-context features (multi-state GST, dealer credit, regional language UI) the global SaaS does not prioritise, or when integration between your tools is the actual problem. For most Indian SMEs the right answer is a layered stack: SaaS for commodities, custom for the differentiators.
| Criterion | Custom Software | SaaS Subscription | Big Helpers take |
|---|---|---|---|
| Upfront cost | ₹50K-15L (one-time build) | ₹0-50K (start free or trial) | SaaS wins on day 1; custom wins by year 2-3 if your seats keep growing. |
| Recurring cost (15 users) | ₹3-10K/month hosting only | ₹2.4-7L/year per tool, multiple tools | Custom is cheaper at scale; SaaS is cheaper if you stay tiny on standard workflows. |
| Time to live | 4-16 weeks | Same day to 4 weeks (configure-only) | SaaS wins on speed. Custom needs real discovery. |
| Workflow fit | 100% — built around your process | ~70-90% — you bend to fit the SaaS | If your workflow is standard, the gap doesn't matter. If it isn't, the gap is everything. |
| India-specific features | GST, e-invoicing, Tally sync, WhatsApp, regional lang | Variable — global SaaS often half-implements India needs | Custom wins for India-heavy workflows; SaaS catches up slowly. |
| Per-seat tax | ₹0 — flat hosting | ₹500-3,500/user/month | Single biggest TCO difference at scale. |
| Integration with other tools | Built to your exact stack | Limited to vendor-supported connectors (or pay extra) | Custom wins when your stack is non-standard or India-specific. |
| Maintenance burden | You hire a developer or pay us a retainer | Vendor handles it — bugs, scaling, security | SaaS wins on operational simplicity. Real cost trade-off for control. |
| Updates / new features | You decide what gets built and when | Vendor decides — you get what they ship | Trade-off: you get strategic control vs free continuous improvement. |
| Lock-in | You own source code + data + can self-host | Data export available; logic stays with vendor | Custom is portable; SaaS lock-in is mild but real. |
| Compliance / audit (DPDP) | Host wherever you want; audit trail to spec | Depends on vendor's India setup; often workable | Both are workable; custom gives absolute residency control. |
| Best for | Differentiating workflows, large user counts | Commodity workflows (accounting, email, generic CRM) | Most SMEs need a layered stack: SaaS for commodities + custom for differentiators. |
| Cost head | Custom Software | SaaS Subscription |
|---|---|---|
| 5-user team — Year 1 (one workflow) | ₹60K-1.5L (build) + ₹30K (hosting) = ₹90K-1.8L | ₹0-50K (Free / Standard SaaS tier) |
| 5-user team — Years 2-3 | ₹30K/year hosting + minor changes | ₹50K-1.5L/year |
| 15-user team — Year 1 (3 workflows) | ₹2-5L (build) + ₹60K (hosting) = ₹2.6-5.6L | ₹2.4-6L/year (multiple SaaS subscriptions) |
| 15-user team — Years 2-3 | ₹60K-1L/year | ₹2.4-6L/year (still) |
| 30-user team — Year 1 | ₹4-10L (build) + ₹1L (hosting) | ₹6-15L/year (full SaaS stack) |
| 30-user team — Years 2-3 | ₹1-2L/year | ₹6-15L/year (still) |

Note: illustrative example — not a specific client engagement.
An illustrative example: a 45-person 4-branch retail chain in Lucknow was running 6 SaaS subscriptions: Zoho CRM Plus (₹3.4L/year), a separate attendance app (₹84K/year), a paid Vyapar Business plan (₹36K/year), AiSensy WhatsApp inbox (₹1.2L/year), Tally on premise, plus Google Workspace. Total SaaS spend ₹5.8L/year. Despite all this, reconciling data between them needed a person 3 days a month, and the owner still couldn't see today's sales across all 4 outlets in one screen. We built a custom layer in 11 weeks for ₹3.8L (one-time) + ₹4,500/month hosting that replaced 4 of the 6 tools (CRM, attendance, billing layer, WhatsApp inbox) and integrated cleanly with the remaining 2 (Tally, Google Workspace). Year-1 spend: ₹3.8L + ₹54K = ₹4.34L (vs ₹5.8L SaaS). Year 2 onward: ₹54K (vs ₹5.8L SaaS). Payback inside year one; the owner now sees the entire business in one screen.
Don't make this a binary — most Indian SMEs win with a layered stack. Buy SaaS for commodity workflows (accounting in Tally, email in Google Workspace, payments via Razorpay). Build custom for the workflows that are either differentiators (your unique sales motion, your specific approval chain) or where SaaS per-seat fees have crossed ₹3-5L/year and your seat count keeps growing. If you're under 10 users with standard workflows, stay all-SaaS. Above 15-20 users with India-specific quirks, start identifying the 1-2 workflows where custom would pay back inside 18 months — and start there.
Only at small scale on commodity workflows. The moment per-seat fees, paid connectors, or feature-tier upgrades start compounding, custom becomes cheaper inside 18-24 months. The crossover point varies — typically 10-15 users for CRM-class tools, 20-25 users for HR/attendance tools, 5-8 users for niche industry SaaS where pricing is aggressive.
Excellent middle path for many SMEs. We deploy and customise ERPNext, Mautic, Chatwoot, Odoo and Frappe regularly. Costs sit between custom build and full SaaS, with most of the ownership benefits. Trade-off: you inherit the open-source project's design choices and upgrade cadence. We will recommend honestly when self-hosted open-source is the right answer.
Yes — and we recommend it for many SMEs. Use SaaS to learn what your actual workflow needs (you'll be surprised how often it differs from what you described upfront). When you outgrow it, the discovery for the custom build is faster because you know exactly what you want. Migration from common SaaS (Zoho, HubSpot, Vyapar, Khatabook) is well-trodden ground.
Yes. We configure Zoho, HubSpot, Pipedrive, Tally, Razorpay setups and ERPNext deployments. We also build custom. The recommendation in this article is honest because we make money either way.
That's the lock-in fear, and it's fair. The mitigation is: standard, well-documented stack (Laravel/Django + PostgreSQL + React/HTMX), source code on your GitHub from day one, documented deployment, and the explicit ability to hire any competent Indian developer to extend or maintain it. We have been Pvt Ltd since 2008 and design every build for the case where we're not around.
Yes — and it's increasingly common. Use SaaS as the source-of-truth for commodity data (Tally for ledgers, Razorpay for payments) and build a thin custom layer that orchestrates between them and exposes the views your business actually wants. Costs less than full custom, gives you most of the workflow control.
