Short answer
A call centre outsourcing business case should define exactly what will be outsourced, how (the model, number of providers and locations), the current fully loaded cost to benchmark against, the risks, and how success will be measured. Compare outsourcing with the alternatives — improving in-house, automation or a hybrid model — and involve customer-facing, finance, IT, legal and data protection teams from the start.
Key points
- Be precise about scope: contact types, channels, volumes, hours and processes.
- Know your true in-house cost, including overheads, before comparing bids.
- Compare outsourcing with in-house improvement, automation and hybrid options.
- Define success in outcomes — resolution, satisfaction, conversion — not just speed and cost.
Why the business case matters
A robust business case does three jobs. It tests whether outsourcing is really the best option. It gives providers the information they need to design and price a realistic solution. And it creates a shared understanding inside your organisation, which reduces the risk of a late change of direction.
It should look at all the options — in-house, outsourced and combinations — and be built around what your customers need, not only what the operation costs.
What the business case must make clear
- What is being outsourced — a detailed scope of contact types, channels, processes and customer groups.
- How it will be outsourced — the model (fully outsourced, hybrid, pilot first), number of providers, and preferred locations.
- The baseline — your current fully loaded cost and performance, against which bids and results will be measured.
- The risks — operational, regulatory, data protection, reputational and people risks, with mitigations.
- How success will be judged — service levels, quality criteria (including the customer experience and agent behaviours you want) and business outcomes.
Checklist: what to include
- Business objectives and background to the decision.
- Descriptions of the services and processes to be outsourced, with process maps.
- Current contact sources, volumes, handle times and patterns (by channel, hour, day and season).
- Forecast volumes and the reasons: marketing plans, growth, product launches, self-service and AI changes.
- Current service levels, quality scores and customer satisfaction.
- Systems, integration, management information and reporting requirements.
- Regulatory and data protection requirements (see compliance and security).
- Timetable and milestones.
- Key people, roles and the governance team you will commit.
- Costs, budget and projected return on investment.
Model the costs honestly
Compare fully loaded costs on both sides. For your in-house operation, include recruitment, training, attrition, facilities, technology, management and support overheads. For outsourcing, add the costs that stay with you: transition, travel, integration, and the governance team that will manage the provider.
Present the result as:
- cost per productive hour,
- cost per contact and per resolved contact, and
- total cost over the contract term, including transition.

Consider the alternatives
- Improve in-house: better workforce planning, coaching or technology may close part of the gap.
- Automate: self-service and AI can remove simple contacts — which also changes what you would outsource. See AI in the contact centre.
- Hybrid: keep sensitive or high-value work in-house and outsource the rest.
- Overflow or out-of-hours only: a lower-risk first step.
Involve the right people early
The teams responsible for the customer experience — customer service, sales, marketing and complaints — care most about the impact on customers. Procurement, finance, HR, IT, information security, legal and data protection will all be involved. Bringing legal and data protection in early is especially important when personal data will be handled offshore.
From business case to shortlist
With the business case agreed, you can describe the kind of provider most likely to meet your objectives: experience, size, capabilities, location and management style. That becomes the basis for your shortlist.
Frequently asked questions
What data do I need to prepare before outsourcing a call centre?
At minimum: contact volumes by channel, hour and day for at least 12 months; average handle times; current service levels and quality scores; process documentation; systems used; and your current fully loaded costs. The more accurate the data, the more accurate and comparable provider pricing will be.
How do I calculate my in-house call centre cost?
Include salaries and benefits for agents, team leaders and support staff; recruitment and training; attrition costs; facilities; technology and telecoms; management overheads; and a share of HR, IT and finance support. Convert this to a cost per productive hour and per resolved contact so you can compare it with provider bids.
