ERP comparison:
pick the right digital core
Choosing an ERP is a decision you live with for years. Compare ERPNext, a custom build, Odoo, SAP Business One and Dynamics 365 on cost, customisation, speed and compliance.
The five-year
cost picture
Licensing models differ, so the total cost of ownership diverges sharply as users grow.
ERPNext
Open-source, no per-user licence.
- No user-licence cost
- Runs on your own infrastructure if you want
- Native GST and e-invoicing
Custom ERP
A bespoke system built to your process.
- Built exactly to process
- You own the IP
- You also own the maintenance
Odoo Enterprise
Modular, app-based suite.
- Large app ecosystem
- Cost grows with users and apps
- Custom modules can break on upgrade
SAP Business One
Long-established enterprise suite.
- Widely recognised standard
- High entry budget
- Consultant day rates dominate cost
MS Dynamics 365
Microsoft ecosystem suite.
- Tight Office 365 integration
- Premium cloud licence tiers
- Longer implementation cycles
How to read these figures. They are indicative five-year totals for a mid-sized deployment, drawn from public list pricing and from projects we have worked on. Your own quotes will differ with users, modules and country. We implement ERPNext, so weigh our comparison accordingly.

Three questions that
settle most decisions
Is your process really unusual?
If your core workflow is standard, a configurable product plus targeted customisation beats a bespoke build on cost and speed.
How many users will you add?
Per-user licensing dominates long-run cost. If headcount grows, licence-free software changes the arithmetic entirely.
What compliance do you need?
Indian GST, e-invoicing and e-Way Bill are native in ERPNext. On other platforms they are usually a localisation pack or an add-on.
