ERP selection matrix for India: Tally, ERPNext, Odoo, SAP Business One or custom
TallyPrime, ERPNext, Odoo and SAP Business One all handle Indian e-invoicing in some form; they differ in how they're licensed, where they run, and how far they bend to your process. A custom system fits the process exactly but has to be built. Score them against your own requirements, weighted by your priorities, not against a vendor's feature list.

How to use this matrix
Don't pick a system from a feature table, this one included. Every option below can be made to look good in a demo. Pick from your own requirements:
- Build your list with the requirements builder and set a priority on each line.
- Send the same Excel template to each option, one copy per vendor. It scores Yes, Partly and No against your priorities.
- Make each vendor do the demo tests for your Must lines. A yes you didn't see counts as partly.
The table below is for the first cut: which options to invite at all. Each fact is from the product's own documentation, linked under sources.
The matrix
| TallyPrime | ERPNext | Odoo | SAP Business One | Custom-built | |
|---|---|---|---|---|---|
| What it is | Accounting and inventory software from Tally Solutions | Open-source ERP from Frappe | ERP suite of apps, Community and Enterprise editions | SAP's ERP for small businesses | A system built around your process |
| Licence | Proprietary licence | GPL-3.0 (open source) | Community: LGPLv3; Enterprise: Odoo's own licence | Proprietary licence | As your contract says: you own the code, or a licence runs with maintenance |
| Where it runs | Your PC or server; TallyPrime's integration gateway listens only on that machine | Self-hosted or Frappe Cloud | Odoo Online, Odoo.sh or on-premise | Cloud or on-premise | Wherever it's built for |
| E-invoice and e-way bill | Built in: IRN, QR code and e-way bill from the sales voucher | Through the India Compliance app (GST, e-invoice, e-way bill, TDS) | India localization modules for e-invoicing (from 15.0) and e-way bill | Through India localization and partner add-ons; check with your partner | Built to the NIC specs, or not at all; ask |
| Audit trail (edit log) | Edit log; a separate release keeps it always on | Check it meets the rule | Check it meets the rule | Check it meets the rule | Must be built in and can't be switched off |
| Fit to your process | You adapt to it | Configurable; customised by developers | Configurable; customised by developers or partners | Configured by partners | The process is modeled first, then built |
| Works alongside Tally | Is Tally | Replaces it, or runs beside it with an integration | Replaces it, or runs beside it with an integration | Replaces it, or runs beside it with an integration | Either: posts into Tally, or keeps the books itself |
"Check it meets the rule" means the product's documentation we read doesn't say, in plain terms, that the edit log meets the audit-trail rule: a log of every change with its date that can't be disabled. Ask the vendor to show it.
When each one tends to fit
- TallyPrime alone: accounting-led businesses whose operations fit in its inventory, and who mainly need GST done right. When it stops being enough is in seven signs you've outgrown Tally.
- ERPNext or Odoo: businesses whose processes are close to the standard modules, with a partner or in-house developer to configure and maintain them.
- SAP Business One: small businesses that want an established vendor and a partner-led implementation.
- Custom: when the process is the business's edge, the standard modules force workarounds, or the system has to do something no package does (an IBR statutory folder from certificates, reel-level reservations, two companies on one ledger).
The longer comparison for manufacturers is Tally, ERPNext, Odoo or a custom ERP.
What the matrix leaves out
Price, deliberately: licence, implementation and maintenance costs change by edition, users and partner, and a number here would be wrong for most readers. Get quotes against the same requirements list, and settle ownership and data export before signing: see the contract checklist. Ahrom Labs builds custom systems, so read this page as a builder's view; the facts about each product are from its own documentation.
