How to analyse an outsourcing decision
An outsourcing decision is more than a unit price comparison. How to weigh avoidable costs, transition risks and control together.
An outsourcing decision is a decision about whether a task is better done in-house or bought from an outside provider. Logistics, payroll, IT infrastructure, cleaning, security and even part of accounting are typical candidates. These decisions are often made on a misleading comparison: the supplier’s quoted price set against the full in-house cost in the accounts. The right comparison is between the costs that will actually disappear with the decision and the total cost of the outside service. In this article I show how to analyse an outsourcing decision across its financial, operational and control dimensions.
The strategic question first
Before any financial analysis, ask: is this activity part of the company’s competitive advantage? Activities that are the reason customers choose the company, and that set it apart from competitors, should usually stay in-house. Support activities that are standardised, and where specialist providers have economies of scale, are better candidates for outsourcing. For a distributor competing on fast delivery, logistics is strategic; for a manufacturer competing on product quality, the same activity may be a support function.
Relevant cost: the cost that changes with the decision
The cost to use in the analysis is not the full cost in the accounting records but the cost that will disappear if the decision is taken — the avoidable cost. The distinction matters most for three kinds of item:
- Allocated overheads: the share of management, rent or IT charged to the in-house activity often does not disappear when it is outsourced; it is simply reallocated to other departments.
- Depreciation: the accounting charge for a past investment. What matters is whether the assets can be sold and for how much, and the replacement investment that would be needed if the activity stays in-house.
- Contractual obligations: one-off costs triggered by the decision, such as lease commitments and staff exit costs.
A hypothetical example: own fleet or a logistics provider?
The example below is entirely hypothetical. A company is considering handing the distribution it runs with its own vehicle fleet to a logistics provider. The provider’s annual quote is TRY 21.5 million. In-house cost looks like this in the accounts:
| Item (TRY million / year) | Accounting amount | Eliminated by the decision? |
|---|---|---|
| Driver wages and benefits | 9.6 | Yes |
| Fuel | 7.2 | Yes |
| Maintenance and repairs | 2.4 | Yes |
| Vehicle depreciation | 3.0 | If the vehicles are sold, the replacement need disappears |
| Insurance | 0.8 | Yes |
| Allocated overhead | 2.0 | Only 0.5 (the fleet manager) |
| Total | 25.0 |
At first sight the saving is 25.0 − 21.5 = TRY 3.5 million. The correct calculation is:
- Overhead that will not disappear: TRY 1.5 million. Avoidable in-house cost: 25.0 − 1.5 = TRY 23.5 million.
- Cost of managing the outsourced service (contract management and performance tracking, a part-time specialist and reporting): about TRY 0.6 million a year.
- Annual net saving: 23.5 − 21.5 − 0.6 = TRY 1.4 million.
- One-off transition costs (staff transfer costs, contract terminations): TRY 1.2 million. Proceeds from selling the vehicles may cover this.
The decision may still be positive, but the saving is less than half the first figure. That gap means the decision has to be weighed against operational risk: a TRY 1.4 million saving may not cover the damage of losing customers after even a small drop in delivery quality.
Non-financial criteria
| Criterion | Question to ask |
|---|---|
| Service quality | Can measurable service levels (on-time delivery, error rate) be written into the contract? |
| Flexibility | How flexible is cost when volume changes? Does fixed cost become variable? |
| Dependence | How hard and costly is it to switch provider? Are there alternatives? |
| Loss of know-how | Could the company retain the knowledge needed to bring the activity back in-house later? |
| Data and confidentiality | Will the provider have access to customer, pricing or personal data? |
Cost flexibility is often the most overlooked benefit. Much of the cost of an in-house fleet is fixed, whereas outside services are usually priced by volume. In a business with volatile sales, this shift lowers the break-even point and protects the company in bad periods. I explain the link between break-even and fixed cost structure in break-even point and margin of safety.
The control dimension
Outsourcing an activity does not outsource its risks. The provider’s transactions still affect the company’s financial statements, customer relationships and reputation. Processes handed to service providers should therefore still be considered within the company’s internal control system. In practice:
- The contract should include service levels, reporting obligations and a right to audit.
- The provider’s invoices should be approved only after reconciling them with measurable service data.
- For critical processes, ask for the provider’s business continuity plan.
The decision process
- Assess the strategic importance of the activity.
- Calculate avoidable costs and one-off transition costs.
- Add contract management cost to the total cost of the outside service.
- Score the non-financial criteria and list the risks.
- Where possible, start with a pilot region or process and measure service levels.
- Write exit terms and a scenario for bringing the activity back in-house into the contract.
Conclusion
An outsourcing decision is much more than comparing a quote with an accounting cost. Its real value emerges when avoidable costs, transition costs, contract management, flexibility and control are assessed together.
