ERPNext vs SAP
ERPNext vs SAP Business One — which, and how we help you move
SAP Business One is the right choice for some Indian mid-market operators; ERPNext is the right choice for others. The honest 2026 comparison is on the long-form guide — this page is the service offer for the mid-market operators that have decided ERPNext is the move and want help with the migration, or for the mid-market operators that are still on the fence and want a short, side-by-side read.
Side by side
| Dimension | ERPNext | SAP Business One |
|---|---|---|
| Per-user licence fee | None (GPL-3.0) | Per-user, perpetual + annual |
| Source code ownership | Yours, on your infrastructure | SAP, on SAP's terms |
| Implementation cost (50-user Indian mid-market operator) | ₹18–35 lakh | ₹40–90 lakh |
| Ongoing cost (50 users, managed) | ₹3–6 lakh / year | ₹8–20 lakh / year (incl. SAP maintenance) |
| Customisation | Native Frappe apps, your repo | B1 SDK, SAP partner only |
| Hosting | Your infrastructure (Hetzner / AWS / on-prem) | SAP HANA Cloud or on-prem HANA |
The detailed feature comparison — every dimension we evaluated and the verdict per row — is on the long-form ERPNext vs SAP guide.
The case for moving
If you are a 50–250 person Indian mid-market operator that has outgrown Tally / Busy and is evaluating SAP Business One against ERPNext, the cost difference is the most striking thing — the implementation cost is typically 2–3× higher on SAP, and the ongoing licence + maintenance keeps compounding every year. ERPNext ships the same operational depth (manufacturing, distribution, multi-branch, project accounting) at the cost of a 2-year SAP maintenance contract. The trade-off is ecosystem: SAP's partner network is broader, and a few vertical-specific processes (complex mill production, certain regulated industries) still favour SAP. If your operations fit ERPNext's breadth and you can run on open source, the TCO math is decisive.
How we help
We deliver SAP → ERPNext migrations for Indian mid-market operators that have decided to move. The engagement follows a fixed flow — discovery, custom-code inventory, data mapping, parallel run, cutover — with a phased go-live across finance, then the rest of the modules. SAP B1 stays as a read-only archive; transaction history does not migrate. Most engagements are 12–20 weeks from kickoff to go-live.
Engagement shape — Fixed-scope or T&M, with a discovery-led scope freeze. Indicative cost band for a 50–200 person mid-market operator: ₹18–35 lakh implementation + ₹3–6 lakh / year for managed hosting. The detailed comparison is on the ERPNext vs SAP Business One guide.
Frequently asked questions
How long does an SAP → ERPNext migration take?
Most engagements are 12–20 weeks from kickoff to go-live. The custom-code inventory and the data-mapping workshops tend to be the long pole, not the cutover itself. We will give you a tighter range once we have seen the SAP module scope in discovery.
What does an SAP → ERPNext migration cost in India?
For a 50–200 person Indian mid-market operator, the implementation cost is typically ₹18–35 lakh, plus ₹3–6 lakh per year for managed hosting. The full range is on our pricing hub — shared by direct link during the conversation.
Does history migrate from SAP to ERPNext?
No — masters, open items, and opening balances migrate; transaction history stays as a read-only archive in SAP. We say this in every conversation, because saying otherwise is the single fastest way to lose an accountant on the first call.
Should we stay on SAP instead?
Possibly, if you have SAP-specific processes (complex mill production, regulated industry, SAP partner ecosystem you lean on) or if your team has deep SAP expertise you do not want to retire. The decision is not about ERPNext being better than SAP; it is about whether the TCO difference is worth the change.
