It depends on which part you mean. An AI agent can do the mechanical work: collect subsidiary trial balances, map them to the group chart, translate currencies at agreed rates and propose eliminations for matched intercompany balances. The judgements, such as which entities are in scope, unexplained differences and goodwill, stay with the group financial controller, who signs off.
What part of consolidation is mechanical?
More than people expect. A large share of a group close is moving numbers between formats: each subsidiary's trial balance, in its own chart and currency, has to be mapped to the group chart of accounts, translated and added up. Then intercompany balances that agree on both sides are eliminated.
An agent does this well because the rules are fixed and the inputs are records. It can map, translate, aggregate and tie out at depth 3 within a consolidation workbook or tool that only it and the group finance team write to. None of that touches the subsidiaries' own books.
What conditions have to be in place?
- A maintained mapping. Every local account maps to one group account. New local accounts are held until a person maps them.
- Agreed rates from a sealed source. Closing and average rates come from the group's chosen rate source, loaded once per period, not looked up by the agent on a web page.
- Closed subsidiary periods. The agent consolidates only trial balances that the local controller has locked.
- Matched intercompany. Eliminations are automatic only where both sides agree within tolerance. Everything else is reported.
- A fixed group structure. Ownership percentages and the list of consolidated entities are inputs a person maintains, not things the agent infers.
What does the agent prepare, and what does the controller decide?
The agent prepares: - the mapped and translated trial balance for each entity; - the translation differences, split by entity; - proposed eliminations for matched intercompany balances, revenue and costs; - a list of intercompany differences with both sides' transaction detail; - the consolidated trial balance and a tie-out to each entity's submission.
The group controller decides: - whether an entity is in or out of the consolidation, and on what basis; - how to treat intercompany differences that do not resolve; - goodwill, fair value adjustments and non-controlling interests; - any top-side adjustment, each of which is drafted by the agent and approved by a named person; - sign-off of the consolidated numbers before they reach management accounts or statutory reporting.
An illustrative example
Take a group with a parent and five subsidiaries, two of which report in a different currency. At quarter end the agent collects five locked trial balances, maps them, and translates the two foreign entities at the closing rate for the balance sheet and the average rate for profit and loss.
Intercompany balances match for four pairs. The fifth does not: the parent shows a receivable of 112,000 from one subsidiary, but the subsidiary's accounts payable shows 100,000. The agent pulls both sides' transactions and finds an invoice of 12,000 raised by the parent on the last day of the quarter that the subsidiary has not yet booked.
It does not force the elimination. It eliminates 100,000, reports the 12,000 as goods in transit with the invoice attached, and drafts a top-side entry for the controller. The controller approves it, and the agent records that the difference should clear next quarter.
Where does the named approver sign off?
At two points. First, every top-side adjustment: these sit outside any subsidiary's books, are the easiest place to manage group results, and auditors examine them closely. The agent can draft them; a named person approves each one, and the approver is not the person who requested it.
Second, the consolidated result as a whole. The group financial controller reviews the tie-outs, differences and judgements before release. That sign-off is a person's, as set out in whether an AI agent can sign off a set of accounts.
What controls make it safe?
- The agent cannot write to subsidiary ledgers. It consolidates; it does not correct local books.
- Mapping changes are approved. A remapped account can move numbers between lines without changing totals, so each change is a recorded decision.
- Differences are never forced. Unmatched intercompany is reported with evidence, not plugged.
- Every top-side entry has an approver. Named, recorded and separate from the preparer.
- Full tie-out. The consolidated trial balance reconciles to each entity's locked submission.
The broader principles are in AI agents for finance: books you can audit.
Questions people ask
Can the agent chase subsidiaries for late trial balances?
Yes. Reminding local controllers of the timetable and listing what is missing is routine work at depth 3. It cannot submit a trial balance on their behalf.
How does the agent handle a change in ownership during the period?
It flags it and stops. Acquisitions, disposals and changes in ownership share involve judgements about dates and values that the group controller makes first.
Can the same agent work across all entities?
It can, with read access to each entity's locked trial balance and write access only to the consolidation. Keeping its access narrow means a mistake cannot spread into local books.
