- Service Level Agreement (SLA)
- A contractual commitment specifying minimum performance standards — such as average speed to answer, first-call resolution rate, and abandonment rate — that the provider must meet.
- Average Handle Time (AHT)
- The average duration of a single customer interaction from the moment the agent answers to the end of any post-call work, used as a KPI in SLAs.
- First-Call Resolution (FCR)
- The percentage of customer contacts resolved in a single interaction without requiring a callback or escalation — a primary quality metric for call centers.
- Business Process Outsourcing (BPO)
- The practice of contracting one or more business functions — including customer support — to an external provider rather than handling them in-house.
- Statement of Work (SOW)
- A schedule or exhibit attached to the master agreement that defines the specific services, volume commitments, locations, staffing levels, and deliverables for a given engagement.
- Data Processing Addendum (DPA)
- A supplemental agreement governing how the provider may collect, store, process, and delete personal data on behalf of the client, required under GDPR, CCPA, and similar regulations.
- Service Credit
- A financial remedy — typically a percentage reduction in the next invoice — owed by the provider to the client when SLA performance falls below the contracted threshold.
- Transition Assistance
- Obligations requiring the outgoing provider to cooperate with handover to a successor vendor, including data export, knowledge transfer, and staffing continuity for a defined period.
- Force Majeure
- A clause excusing a party's non-performance when caused by events outside reasonable control — such as natural disasters, pandemics, or government orders — for a defined period.
- Indemnification
- A contractual obligation requiring one party to compensate the other for losses, claims, or damages arising from a defined category of fault or breach.
- Liability Cap
- A contractual ceiling — often expressed as a multiple of fees paid in the preceding 12 months — limiting the maximum amount either party can recover in damages.
- Change Order
- A written amendment to the Statement of Work that formally modifies scope, volume, pricing, or timelines, requiring signatures from both parties before taking effect.
