SLA in SaaS agreements. How to define responsibility and service availability

Availability is not just a percentage

SaaS agreements often include a service availability commitment, such as 99.5%. Without rules on measurement, maintenance windows, exclusions, incident procedures and consequences of breach, the clause may have limited practical value.

Issues worth structuring

  • what availability means and how it is measured,
  • which interruptions are excluded,
  • response, workaround and repair times,
  • whether RTO and RPO are addressed,
  • whether service credits are the only remedy,
  • exit and access to data after termination.

An SLA should match the architecture of the service, the support model and the customer’s operational needs. Otherwise, it remains a marketing appendix rather than a risk management tool.
