Adding subsidiary balance sheets can count the same economic relationship twice. A receivable in one group company may be a payable in another, while a parent investment corresponds to interests in the subsidiary's equity. Consolidation seeks to present the group under the applicable reporting rules, which requires analysis, adjustments and eliminations. A spreadsheet total without those steps is a combined summary, not automatically a valid set of consolidated accounts.
Start with a defined perimeter and comparable reporting information. Align relevant accounting policies and periods where the rules require it, then document adjustments. Map accounts consistently so similar items are not placed in different categories. Keep each entity's original figures visible alongside consolidation entries. That audit trail helps the team distinguish a local bookkeeping correction from a group adjustment that should not be posted indiscriminately into every company's ledger.
Reconcile intercompany balances with both counterparties before eliminating them. Differences may reflect timing, exchange rates, missing invoices or errors. Do not erase a mismatch by putting the unexplained amount into a convenient adjustment account. Transactions within the group can also affect reported revenue, expenses and profit embedded in assets. Their treatment needs examination beyond merely cancelling outstanding receivables and payables at the reporting date.
For a hypothetical manufacturing group, one company sells goods to another and some remain unsold to outside customers. The internal sale has created a margin within the group, but its treatment in consolidated stock and results needs review under the consolidation rules. Eliminating only the outstanding invoice would not address the full reporting question. Ownership proportions and other circumstances can add further considerations for the consolidation team.
Prepare schedules for investments, equity movements, intragroup transactions and relevant ownership changes. Where acquisition accounting or noncontrolling interests arise, obtain appropriate technical input instead of applying a simple percentage to every line. The aim is a coherent group presentation supported by identifiable calculations. Keep tax effects of adjustments within the review where relevant, without assuming that accounting consolidation changes how each company's tax return is filed.
A useful consolidation file explains each adjustment, its source and who reviewed it. Reconcile the final statements to the adjusted information and required disclosures. A consolidation process review can identify where raw addition has replaced necessary analysis, helping the group produce figures that reflect its structure and transactions rather than merely the total of individual trial balances.
