Shared Services Pricing

Shared Services Pricing
Shared services pricing is how an internal service centre charges its own business units for the work it does, converting a central cost pool into recoverable rates. The allocation base decides everything, because it quietly determines which unit pays for what.
Three approaches exist, and organisations move between them as they mature. Costs can be absorbed centrally, allocated by a formula, or charged against actual consumption at published rates.
Each choice changes behaviour — free services get over-consumed, formula allocations get argued about, and consumption charging produces the most discipline and the most administration.
The published rate is also a test. A business unit that can see the price will eventually ask what the same service costs outside — which is exactly the pressure a shared service centre should feel.
Key takeaways
- Absorption, allocation and chargeback are three different models with different effects.
- The allocation base should reflect the benefit each unit actually receives.
- Published rates invite external comparison, which is a feature rather than a flaw.
- A service catalogue with defined units is needed before any rate means anything.
How it works
The underlying principle is allocability. Federal cost principles state that “a cost is allocable if it is assignable or chargeable to one or more cost objectives on the basis of relative benefits received or other equitable relationship”.
The same rules describe how a base should behave, requiring that “the base selected shall allocate the grouping on the basis of the benefits accruing to intermediate and final cost objectives”.
Grant accounting reaches the same place from a different direction. A cost is allocable where it “benefits both the Federal award and other work of the recipient or subrecipient and can be distributed in proportions that may be approximated using reasonable methods”.
| Model | How units are charged | Behavioural effect |
|---|---|---|
| Absorption | Not charged at all | Over-consumption, no cost visibility |
| Headcount allocation | By staff numbers | Simple, often unfair to lean units |
| Revenue allocation | By unit turnover | Penalises growth, easy to administer |
| Activity allocation | By measured drivers | Fair, costs more to run |
| Consumption chargeback | By units consumed at rates | Strongest discipline, most admin |
Allocation bases should be chosen for fairness, not for ease — charging finance costs by headcount when the driver is transaction volume subsidises whichever unit generates the most invoices.
A service catalogue comes before rates. Without defined units, a chargeback model is simply an allocation with extra paperwork attached.
Examples
Chargeback models change behaviour quickly, which is the point and also the risk. These four cases show the effects, including one that produced an unintended result.
A manufacturer moves payroll services from headcount allocation to per-payslip chargeback. Two business units immediately clean up duplicate records they had ignored for years.
A retailer allocates IT cost by revenue. Its fastest-growing division carries a disproportionate share and starts building its own shadow capability instead.
A bank charges finance services by transaction volume using measured drivers. Costs land where the work is generated and cross-subsidy between divisions largely stops.
A group absorbs all shared service cost centrally with no charge. Demand grows faster than the workforce for three years, because the service appears free to everyone using it.
Related terms
Shared service arrangements are described with several terms that differ in ownership and in who the internal customer actually is. The entries below separate them, because the pricing question changes with each structure.
- Shared services: the operating model this pricing supports.
- Shared services centre: the organisation that issues the charges.
- Shared service outsourcing: handing the centre itself to a provider.
- Captive shared services: an offshore-owned centre serving internal units.
- Activity based costing: the technique that produces defensible allocation drivers.
- Finance and accounting outsourcing: the function most often charged this way.
- Total cost: the group view that chargeback redistributes rather than reduces.
FAQ
What is the difference between allocation and chargeback?
Allocation divides a total across units by a formula. Chargeback prices defined services and bills for what each unit actually consumes.
Which allocation base is fairest?
The one closest to what drives the cost. Transaction volume beats headcount for finance services, and headcount beats revenue for most human resources work.
Does chargeback save money?
Not directly. It redistributes cost and changes demand, and the saving comes from behaviour change rather than from the accounting itself.
Should internal rates be benchmarked externally?
Yes, and expect uncomfortable conversations. A centre priced above the market will be asked why, which is a legitimate question.
What does a service catalogue need?
A defined unit for each service, a stated inclusion list, a rate and a service level. Anything less is an allocation with a catalogue cover.
How is this different from captive center pricing?
Captive pricing is an intercompany, cross-border tax matter. Shared services pricing is an internal management accounting one, with no arm’s length requirement.
