Your ERP stays
the system of record.
OHM reads from the system that already holds your books and posts outcomes back into it. There is no migration, no second ledger, and nothing to reconcile between the two.
Where the books already live
Tally
The books most of Indian mid-market actually runs on.
SAP
Checks at entry, in the system that already holds the controls.
Oracle
Every invoice checked, not the ones that hit a workflow rule.
Oracle NetSuite
Multi-entity, multi-currency, and the same six leaks.
Zoho Books
Small finance team, same statutory exposure.
QuickBooks
Bills approved on trust, checked on evidence.
Sage
Controls that run per transaction, not per period.
Odoo
Configurable enough to be inconsistent.
The list above is where we have done the work of knowing the data model. It is not a gate. The savings check runs on a purchase register or an AP extract, and every ERP produces one — including the one you built yourself.
