Hi, I’d be cautious about unwinding the current setup in one step. The standard framework can reduce custom maintenance through cross charges, automated intercompany balances, and netting, but it may not replace every custom allocation or auto-balancing rule already embedded in your processes.
Also, NetSuite states that Intercompany Framework and Automated Intercompany Management cannot be disabled after they are enabled, so this should be treated as a significant architecture change.
I would recommend testing it in Sandbox first.
