Service Level Agreement (SLA)

A contract that defines the performance standards a vendor commits to, including uptime, response times, and remedies for failures.

An SLA is a formal commitment about service quality. In SaaS, SLAs most commonly cover uptime (the percentage of time the service is operational), support response times (how quickly the vendor acknowledges and resolves issues), and data recovery objectives. SLAs specify what happens when commitments are not met — typically service credits proportional to downtime duration. Enterprises require SLAs before signing contracts because they need to manage their own operational risk and may have their own uptime commitments to their customers. SLAs also shape product engineering priorities: committing to 99.9% uptime forces investment in redundancy, monitoring, and incident response processes. For the vendor, SLA commitments are marketing signals about the maturity and reliability of the platform.
