A contractual commitment between a service provider and customer that defines measurable performance standards, including uptime guarantees, response times, resolution windows, and remedies for non-compliance.
Every vendor will tell you they offer a 99.9 percent uptime SLA. That number is table stakes, and by itself it tells you almost nothing about the quality of support you’ll actually receive.
An SLA worth negotiating goes beyond uptime percentages to define what happens when things go wrong. Response time by severity level. Escalation paths when the standard response isn’t fast enough. Resolution windows that distinguish between acknowledging a ticket and actually fixing the problem. Data recovery commitments if the platform loses or corrupts your data. And most critically, the specific remedies (typically service credits or contract adjustments) the vendor owes you when they miss their commitments.
The remedies gap
Most standard SLA remedies are designed to cost the vendor very little. A 5 percent service credit for missing uptime by a few hours doesn’t come close to covering the business impact of an email platform going down during a product launch or a CDP losing 48 hours of event data. The negotiation opportunity is in defining remedies that are proportional to business impact, not just proportional to the monthly fee.
Organizations with leverage (large contracts, multi-year commitments, or vendor references) can negotiate SLAs that include direct financial remedies, accelerated termination rights, or performance review triggers. Organizations without leverage should at least understand what the standard SLA doesn’t cover, so they can build contingency plans around the gaps.
