Comparison
Custom ERP vs Off-the-Shelf ERP
Which is right for your business?
A practical comparison for Indian MSMEs deciding between SAP, Tally, Zoho, Odoo, and a custom-built solution.
Head-to-Head Comparison
| Aspect | Custom ERP (Simplovative) | Off-the-Shelf (SAP / Zoho / Odoo) |
|---|---|---|
| Fit to your process | Built exactly around how you work — your terminology, workflows, approval chains | You adapt your process to fit the software. Often requires workarounds. |
| Upfront cost | Higher one-time development investment | Lower upfront — but licensing fees compound every year |
| Long-term cost | Low monthly SaaS fee. No per-user licensing traps. | Per-user/per-module fees grow as your team grows. SAP: ₹5–15L/yr |
| Implementation time | 8–12 weeks to go live with a system that's already right | 6–18 months of configuration, consulting, and training — often longer for SAP |
| Data ownership | You own the code and data. No vendor lock-in. | Data locked in the vendor's system. Exporting is complex and costly. |
| Flexibility to change | Change requests handled in days. You're not waiting for a vendor roadmap. | Changes depend on vendor's release cycle. Customisation often costs extra. |
| GST & Indian compliance | Built specifically for Indian tax law — GST, e-invoicing, TDS as needed | Varies. SAP and Zoho have India compliance. Tally is India-first. |
| User adoption | Designed for your team's workflow — lower learning curve | Generic UI that staff often resist. Training costs are significant. |
| Support | Direct access to the team that built it. Issues fixed fast. | Ticketing systems, long queues, or expensive consulting partners |
How to decide
Choose custom ERP if…
- Your business process doesn't fit standard templates
- You have unique approval chains or multi-level workflows
- You want to own the software, not rent it forever
- You're scaling and don't want per-user fees to compound
- You need specific integrations (GST portal, Razorpay, WhatsApp)
- Your team finds existing tools too complex or too rigid
Choose off-the-shelf if…
- You're a startup that needs accounting software fast (use Tally/Zoho)
- Your process is highly standard with no unique workflows
- You have less than 5 employees and minimal operations
- You need something running today with zero budget
- Your industry has a well-supported vertical SaaS solution
The real cost over 3 years
Off-the-shelf looks cheaper on day one — but adds up fast.
Custom ERP (Simplovative)
Year 1Development + 12 months SaaS
Year 2SaaS (₹9K/mo) + AMC
Year 3SaaS (₹9K/mo) + AMC
You own the software. Costs stay flat.
SAP / Odoo (typical)
Year 1Implementation + licensing: ₹8–20L
Year 2Annual licensing: ₹4–12L
Year 3Licensing + upgrade: ₹5–15L
Licensing never stops. You own nothing.
