Cost Allocation

Cost allocation distributes shared costs to the departments, projects, or entities that benefit from them. When your company pays a $50,000 IT infrastructure bill, cost allocation determines how much of that cost each department should bear based on their usage, headcount, revenue, or other allocation bases. AI-native ERP handles this with a structured workflow that ensures accuracy, auditability, and proper GL posting.

How Allocation Works#

The allocation system uses a plugin-based architecture. The core platform stores allocation runs and their line items, validates accounting integrity, and posts journal entries. The actual allocation logic -- determining which cost centers receive what percentage and calculating the amounts -- is handled by agents or plugins that read your financial data, apply your allocation rules, and submit the calculated results.

This separation means you can implement any allocation methodology (headcount-based, revenue-based, square-footage-based, activity-based, or hybrid) without changing the core system. The allocation rules live in your configuration, not in application code.

Allocation Run Lifecycle#

Every allocation follows a structured lifecycle. You create a draft allocation run, optionally linking it to a source transaction (like the IT vendor bill that triggered the allocation). The calculation agent or plugin computes the debit-credit splits and submits them as allocation lines. You review the calculated amounts, approve the run, and execute it.

Execution creates a journal entry through the standard transaction posting engine, ensuring the allocation follows the same accounting controls as any other GL entry. Debits equal credits, period assignments are validated, and the entry posts to the correct fiscal period.

Document-Linked Allocations#

When you allocate costs from a specific source document -- a vendor bill, journal entry, or expense report -- the system maintains a link between the source transaction and the allocation run. This prevents double-allocation (the same cost being allocated twice) and provides complete traceability from the original expense through the allocation to the target cost centers.

Three Allocation Types#

The system supports three allocation types. Cost allocation distributes expense amounts across recipients. Revenue allocation apportions income to business units or projects. Intercompany charges create cross-entity allocations with proper intercompany accounting treatment.

Reversal and Correction#

If an allocation was posted incorrectly, you can void it. Voiding creates a reversing journal entry that cancels the original allocation, preserving the audit trail. You can then create a new allocation run with corrected amounts and post it.
