Any company with two or more legal entities or subsidiaries that transact with one another has intercompany accounting. Intercompany Accounting (ICA) is owned by the controllership function along with core responsibilities like financial reporting, consolidation, close, financial analysis, management reporting, cash flow, and reconciliations.
ICA encompasses:
Because these transactions occur between legally distinct entities, they introduce risks that make ICA more than just an accounting exercise. There are often implications for Tax and Treasury because ICA can move revenues and profits to different entities or jurisdictions and accrual transactions between entities eventually need to be settled with cash.
Whenever a transaction occurs between two or more entities, whether a cash sweep to a centralized treasury entity or an internal sale of goods or services, the transaction must be recorded completely, accurately, and consistently by all parties. If one entity omits its entry, records an incorrect amount, applies the wrong currency, or posts in a different period, intercompany balances will fall out of alignment and directly impact consolidation.
Lastly, foreign currency exchange (FX) and purchase accounting often add further complexity to intercompany accounting. While these topics are outside the scope of this paper and will be addressed separately, they frequently have a significant impact on intercompany balances, operational complexity, and financial risk.
Here is a list of common intercompany challenges that we often see clients struggle with. If these challenges sound familiar, Eliassen Business Advisory Solutions can help your organization streamline intercompany processes, reduce risk, and free up Finance teams to focus on higher‑value priorities.
Here are some examples of controls or best practices that our Business Advisory Solutions team has implemented at clients in the past. Our consultants have experience with intercompany and consolidation at both large public companies and private clients.
Journal Entry Controls:
Strong controls over intercompany journal entries are essential to ensure completeness and accuracy.
Regular Communication Between Controllership, Tax, and Treasury: Intercompany transactions often have Tax or Treasury implications in addition to financial reporting or accounting risk. The frequency and form of communication may differ, but a regular quarterly or semi-annual touchpoint between these functions often helps identify issues timely and ensure that policies and controls evolve as needed to manage intercompany risk across these key stakeholders. Consider if other shared services like payroll or A/P are impacted by intercompany and include them as well if appropriate.
Monthly Reconciliation and Monitoring: Intercompany accounts should be reconciled monthly to identify and resolve discrepancies promptly.
Above is an example of a simple matrix reconciliation for 6 entities, all in balance. The three trading partner relationships shown are in balance. Each entity and trading partner agrees on the Intercompany Receivable or Payable balance, without variance. The grey diagonal line of cells are the zero balances between each entity and itself.
Effective intercompany accounting is foundational to accurate consolidation, timely close, and reliable financial reporting. While intercompany activity is inherently complex, spanning multiple entities, systems, currencies, and jurisdictions, strong controls, disciplined processes, and proactive reconciliation can significantly reduce risk. Organizations that invest in well-designed intercompany governance and controls not only avoid out-of-balance conditions and financial misstatements, but also preserve their Finance & Accounting capacity, support tax compliance, and enable smoother M&A execution. In short, intercompany accounting done well is not just a technical necessity, it is a strategic enabler of financial clarity and control.
