Short answer
A call centre outsourcing contract should cover scope, service levels and KPIs, quality measurement, pricing and indexation, service credits and incentives, governance, data protection (including cross-border transfer clauses), information security, business continuity, audit rights, subcontracting and location restrictions, change control, and exit and transition-back arrangements. Service levels should balance efficiency measures with quality and outcome measures, so agents are not pushed to end conversations quickly at the customer's expense.
Key points
- Keep KPIs few and focused on results, not only activity.
- Link a portion of fees to quality and outcomes, not just speed.
- Lock down data location, subcontracting and transfer mechanisms.
- Agree exit and handover terms at the start, when goodwill is highest.

Service levels that measure what matters
Traditional contact centre contracts measure productivity: calls per hour, average handle time, speed of answer. These matter, but on their own they encourage behaviour that can hurt customers — tight scripts, rushed calls and transfers. Good performance metrics measure results, not just activity, and are kept to a minimum.
A balanced SLA typically combines:
- Accessibility: service level, abandon rate, response times for digital channels.
- Effectiveness: first-contact resolution, repeat-contact rate, complaints.
- Quality: evaluated conversation quality against an agreed framework.
- Customer outcome: satisfaction (CSAT), effort (CES) or Net Promoter Score.
- Business outcome: sales conversion, retention saves or collections recovery, where relevant.
Productivity measures should support these rather than dominate them. Where confidence in measurement is high, it is reasonable to link a share of fees or credits to quality and outcomes. See measuring call quality.
Pricing mechanics
- Base rates and how they change with volume bands.
- One-off costs for transition, recruitment and training.
- Annual indexation (for example linked to wage inflation or an agreed index).
- Exchange-rate mechanism if costs and pricing are in different currencies.
- How forecasting accuracy is shared — who bears the cost of large forecast errors.
Data protection and location
If the provider will handle personal data of UK, EU, US or Australian customers, the contract must:
- define each party’s role and processing instructions;
- include an approved transfer mechanism for UK or EU data — such as the UK International Data Transfer Agreement (IDTA) or the UK Addendum to the EU Standard Contractual Clauses;
- fix the delivery locations and require consent for any change or subcontracting;
- set breach-notification timelines and cooperation duties;
- provide audit rights.
Vague wording such as “data will be handled with due regard to relevant legislation” is not enough. See compliance and security.
Exit planning
Agree what happens at the end of the contract while relationships are good: transition assistance, knowledge transfer, handover of process documentation, return and deletion of data, and the option for staff or systems to transfer where appropriate.

Frequently asked questions
What KPIs should be in a call centre SLA?
A balanced set usually includes service level (share of contacts answered within a target time), abandon rate, first-contact resolution, quality score, customer satisfaction or effort, schedule adherence, and for sales or collections, conversion or recovery rates. Keep the contractual set small and track the rest in operational reporting.
What are service credits in outsourcing contracts?
Service credits are fee reductions applied when the provider misses agreed service levels. They should be meaningful but proportionate, often capped at a percentage of monthly fees, and can be balanced with earn-back or incentive payments for exceeding targets.
Can an outsourcing provider move my work to another country?
Only if the contract allows it. Your contract should state where services will be delivered and where data will be stored and accessed, and require your written consent before any change of location or use of subcontractors.
