Ask both of them
From the Consolidation guide. Put the same questions to each vendor and compare the answers against your checklist.
- Load two of our entities in different currencies and show the translated, consolidated balance sheet.
- Show an intercompany mismatch and how each counterparty sees and resolves it.
- Trace one consolidated revenue figure back to the entity ledgers and every adjustment.
- Add an acquired entity halfway through a period. What changes?
- How are rate tables loaded and who can change them?
- What leaves with us if we cancel: rules, mappings and history, or data only?
