Start with the finance work that no longer closes cleanly
IBM i accounting software becomes a buying question when finance spends too much time moving data, reconciling systems, rebuilding reports, or proving what changed. The answer is not always a new general ledger. Sometimes the ERP module is sound and the real gap is reporting, workflow, consolidation, or audit evidence.
Keep finance inside the ERP when transactions, controls, and close work still fit. Add a focused tool when one layer is weak. Consider a dedicated financial platform when the current structure cannot support entities, currencies, controls, or reporting without repeated manual repair.
Choose the smallest finance change that solves the real gap
Use the close process as the test. Follow entries from source transaction to reconciliation, approval, financial statement, adjustment, and audit evidence before deciding what must change.

Proof to request |
|
Keep the ERP finance module
|
The ledger and subledgers are trusted, the close is controlled, and most pain comes from access or presentation. |
Workarounds that look small but consume days every month. |
A complete close calendar with the manual steps, owners, and hours made visible. |
|
Add reporting or reconciliation
|
Core accounting works, but teams merge spreadsheets, match transactions by hand, or wait for custom reports. |
A second truth source that changes numbers outside the controlled ledger. |
One real reconciliation and one management report produced with traceable definitions and exceptions. |
|
Move to dedicated accounting software
|
Multi-entity, currency, consolidation, audit, or control needs no longer fit the ERP finance design. |
Broken order, inventory, payroll, tax, banking, and document handoffs after separation. |
A transaction traced from the IBM i source through posting, consolidation, reporting, correction, and audit history. |

Build the plan around the close calendar
Finance software changes affect controllers, auditors, banking, tax, payroll, operations, and IT. Plan the work around a real close cycle. Name every source, approval, reconciliation, report, exception, and owner. Then test a parallel close before cutover so the business can compare results and roll back without guessing.
