The question we hear most often from a CFO evaluating an exit from NetSuite is not “can ERPNext do what NetSuite does?” — it usually can. The question is “what does it actually cost over five years, end to end?” Vendor list prices answer almost none of that, so here is the structure we use to model it honestly.
Where NetSuite cost actually comes from
NetSuite pricing has three moving parts, and only the first one is on the rate card:
- The base license — an annual platform fee.
- Per-user fees — every full user is a recurring line item. This is the part that compounds: each hire is a permanent cost increase, and you are penalized for growing.
- Modules and renewals — advanced modules (manufacturing, demand planning, OneWorld) are priced separately, and renewal uplifts of 5–10% are common once you are committed and migration friction is high.
The trap is that the headline number you negotiate in year one is the smallest number you will ever pay. Users, modules, and uplifts all move in one direction.
Where ERPNext cost actually comes from
A self-hosted ERPNext deployment on Google Cloud inverts the model:
- No license fee. ERPNext is open-source (GPLv3). There is no software license and no per-user cost — adding your hundredth user costs the same in software as your first.
- Compute at cost. You pay Google Cloud for the VM, database, and storage your instance actually consumes. For most small-to-mid deployments that is a few hundred dollars a month, and it scales with load, not headcount.
- Implementation and management. This is the real spend: deploying the system, migrating your data, and managing security and operations over time. It is a service cost, not a rent.
The five-year shape
The reason the five-year view matters is that the two models have different slopes. NetSuite’s line climbs every time you hire or renew. The ERPNext line is dominated by a larger up-front implementation, then flattens to a predictable management retainer plus modest compute.
For a 50-user company, the per-seat model alone is frequently $90,000+ per year before modules. The owned-infrastructure model typically lands a 40–70% lower total cost of ownership over five years once implementation is amortized — and you finish the period owning a depreciable asset instead of a stack of renewals.

The part that does not show up in a spreadsheet
Two costs never appear on either rate card:
- Exit cost. With NetSuite, your data lives in their cloud and leaving is expensive by design. With a sovereign ERPNext deployment you hold the encryption keys and the codebase — if you ever leave Infinary, you take the running system with you.
- The growth penalty. Per-user pricing quietly taxes the exact thing you are trying to do: grow. Removing that tax changes how you staff, not just what you pay.
