Assess the ability of your information systems to feed a reliable IFRS consolidation.
Completeness
Is all required data available?
Reliability
Is the data consistent and reconciled?
Granularity
Is the level of detail sufficient for IFRS adjustments?
Source mapping: General Ledger, sub-ledgers, contract management, intercompany transactions
Account mapping & data model
Build the bridge between your current chart of accounts and target IFRS financial statements.
Mapping table
Local accounting standards accounts to IFRS financial statement line items
Target data model
Tables and fields required for IFRS consolidation
