Cost Allocation Software
Cost allocation software built for intercompany charges
Most cost allocation software stops at a management reporting split. Recharging group costs is where transfer pricing policy meets accounting reality, and that is usually where good intentions fall apart. This module builds an activity-based allocation model your finance team can operate every month and your auditors can follow unaided.
- Activity-based pools with a documented driver behind each one
- Multi-step waterfall from cost centre to activity to entity
- Cost-plus markup applied in line with your TP policy
- Posting-ready charge, schedule and audit documentation
Capabilities
What the cost allocation module actually does
Six capabilities separate a working intercompany allocation model from a spreadsheet that happens to divide numbers. Each one exists because a group somewhere had to explain a recharge to an auditor and could not, and each is designed so the answer to 'why this number' is already in the file.
Activity-based cost pools
Costs are grouped by activity, such as finance, IT, HR, product, or marketing, rather than by cost centre, so allocations reflect what people actually do across the business. This activity-based view avoids the distortions that arise when historic organisational structures are used as a proxy for genuine cost drivers.
Multi-step allocation waterfall
Costs flow from cost centre to activity to beneficiary entity through a series of defensible allocation keys, including headcount, revenue, transaction volumes, or custom drivers agreed with your team. Each step in the waterfall is visible and adjustable, so the logic behind every recharge can be explained and defended.
Full traceability
Every cost line is traceable from its origin in the ERP through to the entity that ultimately bears it, with no black-box waterfalls hiding the mechanics along the way. This end-to-end visibility gives finance and tax teams confidence when explaining recharges to management, auditors, or tax authorities during a review.
Change-friendly configuration
Adding an entity, changing a driver, or rebalancing a pool no longer means rebuilding a spreadsheet from scratch, because the tool recalculates every allocation in seconds. This makes it straightforward to keep the model current as the group restructures, acquires businesses, or introduces new shared services.
Markup and policy application
Cost-plus markups are applied at the pool or service line level in line with your transfer pricing policy, rather than bolted on at the end of the process. The result is a charge that already reflects the agreed method, so the invoice, the documentation and the policy do not drift apart between reporting periods.
Posting-ready outputs
The model produces the intercompany charge per entity, the supporting allocation schedule and an export your accounting system can ingest without re-keying. Finance reviews and approves the numbers instead of rebuilding them each period, which removes both effort and the transcription errors that manual grids invite.
How it works
Four steps from ledger to invoice
- Load the general ledger extract and map cost centres to activity-based pools
- Define the allocation driver for each pool and evidence the choice in the model
- Run the waterfall from cost centre to activity to beneficiary entity
- Apply the policy markup and produce the charge, schedule and posting file
Why it holds up
What makes the allocation defensible
- One documented driver per pool, so no single blanket key distorts the whole allocation
- Every figure traces back from the invoice to the originating ledger line
- Reruns in seconds when entities, drivers or the cost base change mid-year
- Allocation logic is configuration, not fragile spreadsheet formulas nobody owns
- Output covers the charge, the schedule and the audit documentation together

Where cost allocation sits in the wider IC Tool
Cost allocation feeds the rest of the intercompany process. Once the pools and drivers are agreed, the same model drives hourly service rates, the entity-level impact of each charge, the VAT position it creates and the reconciliation that has to clear before consolidation each period.
See cost allocation run on your own cost base
Book a demo to see activity-based allocation running on your actual cost centres, activities and entity structure rather than a generic example. You will see the full waterfall from source cost to final recharge, the documentation it produces, and how quickly the model adapts when drivers or entities change during the year.
Frequently asked
Cost allocation software FAQ
What is cost allocation software?+
Cost allocation software takes a shared cost base and distributes it across the entities, activities or departments that consume it, using defined drivers rather than manual spreadsheet judgement. In a group context it also has to produce the intercompany charge, the supporting evidence and an audit trail that links each figure back to the ledger.
How is this different from a spreadsheet model?+
A spreadsheet can allocate costs once; the difficulty is repeating it every period as entities, drivers and cost centres change. The tool holds the allocation logic as configuration rather than formulas, recalculates in seconds when something moves, and keeps a versioned record of what changed, who changed it and which period it affected.
Which allocation keys can it use?+
Any driver you can evidence: headcount or full-time equivalents, revenue, transaction or ticket volumes, server usage, floor space, or a bespoke key agreed with your tax adviser. Multiple keys can operate in the same model, each applied to the pool it genuinely reflects, so IT is not allocated on the same basis as marketing.
What is activity-based costing (ABC)?+
Activity-based costing allocates indirect costs according to the activities that actually drive them, rather than one blanket key applied across the group. It gives a sharper picture of what each entity consumes, which in turn supports stronger transfer pricing documentation, cleaner management reporting and fewer arguments during a tax authority review.
Does it integrate with our ERP?+
The model runs off general ledger extracts from NetSuite, SAP, Xero and comparable systems, so no direct system access or IT project is required to get started. Where a live integration is wanted, cost data can be fed on a scheduled basis and the resulting charges exported back in a posting-ready format.
Is the output ready for audit?+
Yes. Every allocation is documented with its cost pool, driver, source data and calculation steps, giving a complete record of how each figure was reached. That documentation is built for both internal management reporting and external scrutiny, so a statutory auditor or tax inspector can follow the logic without a verbal explanation.
