ERP & Finance Integration

The Ledger, Stock and Network Assets

What an ERP owns in a telco and what it does not: the ledger, payables, fixed assets, procurement, stock and warehouse, and where they meet Lead-to-Cash. Who owns receivables, why IFRS 15 makes the ledger differ from the invoice, how network build becomes a fixed asset, the integration boundary and the vendor landscape.
