The contractual definition of the service standard a supplier commits to, with measurable targets and remedies, usually service credits, when they are missed. Protection on paper; an incentive structure in practice.
An SLA does not guarantee performance. It prices non-performance. Whether that price actually changes supplier behaviour is the question most buyers never run before signing.

Operators who have managed suppliers against these clauses can tell you which protections are real before you commit.
Pressure-test your shortlistA service level agreement is the part of a services or technology contract that defines measurable performance standards, availability, response time, resolution time, throughput, together with how they are measured, reported and remedied. The standard remedy is a service credit: a defined discount when a target is missed.
The decision-relevant test of an SLA is whether the remedy is large enough to change the supplier's economics. A credit worth two per cent of monthly fees for an outage that stops your order flow is not an incentive; it is a licence fee for failure, and a well-run supplier will treat chronic underperformance as a rational commercial position if fixing it costs more than the credits do. What an SLA reliably buys is different and still valuable: an agreed measurement regime, a reporting obligation, and an escalation path with contractual teeth behind it.
