The intercompany ledger is the detailed record of current account positions between companies of the same group. Among the intercompany accounts of the French chart, it is carried by account 451, groupe, and records what each group company owes to, or is owed by, the others outside of ordinary trade flows.
Account 451 is subdivided by counterparty in practice. A group of six companies opens a sub-account per counterparty entity, so that the position with each one is readable on its own. Without that subdivision the account shows a single net figure that no accountant can justify line by line, which is exactly what a statutory auditor asks for.
What lands in 451 is broad, and that breadth is the difficulty. Cash advances, sweeps from a zero balancing arrangement, cost recharges, accrued interest on intragroup positions, and settlement of invoices between entities all accumulate in the same account. A single 451 sub-account can carry several hundred movements a year of four or five different natures.
Justifying its balance at close therefore means reconstructing a history, movement by movement, against the counterparty's mirror account. Every movement must exist on both sides, at the same amount and in the same period. Any residual is an intercompany mismatch that blocks intercompany elimination.
This is the volume where manual reconciliation stops scaling. Phacet's intercompany flow reconciliation agent compares the two sides continuously rather than at year end, documents each matched pair with an audit trail, and escalates only what does not agree. See trial balance review for the wider account justification exercise.
