How Intercompany Postings Work
Business Central allows organizations to define intercompany partners, map corresponding general ledger accounts, assign inboxes for document exchange, and configure transaction rules between companies. When an intercompany journal, invoice, or other supported transaction is created in one company, Business Central generates the related transaction for the destination company. Each company reviews and posts its own entries, preserving independent accounting records while maintaining consistency across the group.
Organizations implementing Microsoft Dynamics 365 Business Central often explore How ERP and Business Processes Work Together to understand how ERP integration supports shared financial processes, clean-core architecture, and standardized intercompany operations.

Core Components
Effective intercompany processing depends on properly configured master data and standardized accounting policies.
- Intercompany partner setup defining participating companies.
- G/L account mapping to ensure consistent postings.
- Inbox and outbox transactions for secure document exchange.
- Dimension mapping for consistent reporting across entities.
- Approval and posting controls before transactions become part of the ledger.
- Currency support for multinational organizations.
Practical Business Example
Assume Company A provides consulting services worth $50,000 to Company B. Company A records intercompany revenue and an amount receivable, while Company B records the corresponding expense and payable. Business Central exchanges the transaction information so that each legal entity maintains matching accounting records. During consolidation, these reciprocal balances can be identified and appropriately eliminated to present group financial statements accurately.
If internal procurement activities generate a purchase order between related companies, consistent intercompany mappings help ensure both organizations record matching financial events while supporting approval controls and spend visibility.
Business Benefits and Related Concepts
Intercompany postings reduce manual duplication, improve financial consistency, and simplify month-end reconciliation across multiple legal entities. Standardized processing also provides greater visibility into internal trading relationships and supports timely financial reporting.
Organizations managing shared accounting functions frequently reference Central Finance, which describes centralized financial management across multiple entities while preserving individual company operations.
Companies financing subsidiaries may encounter Intercompany Interest, the accounting concept describing interest charged on balances or loans between related entities, which should be recorded consistently across participating companies.
Global organizations also rely on Central Bank Exchange Rates when translating foreign currency intercompany transactions to maintain accurate financial statements and consolidated reporting.
Best Practices
Organizations should establish standardized charts of accounts, consistent dimension structures, clearly defined partner relationships, and regular reconciliation procedures. Reviewing unmatched transactions before period-end helps maintain accurate financial records and smoother consolidations.
