Service Level Agreement (SLA) Template

Definition

A Service Level Agreement (SLA) is a contractual commitment between a buyer and vendor that defines the minimum acceptable performance standards — including uptime, response times, resolution times, and quality metrics — along with the remedies available when those standards are not met.

What’s Included in This Template

Without an SLA, vendor performance expectations exist only in email threads and informal conversations. This template codifies every performance commitment into a legally enforceable framework — from uptime percentages to escalation paths and financial penalties for breaches.

5 Steps to Use This Template

1. Define the services covered by this SLA precisely — The SLA should cover only the specific services listed in the vendor contract’s Scope of Services. A broad SLA covering undefined services creates disputes. List each service component explicitly.
2. Set uptime targets based on your business criticality — A 99.9% uptime SLA allows ~8.7 hours downtime/year. 99.95% allows ~4.4 hours. 99.99% (‘four nines’) allows ~52 minutes. Set targets proportional to the vendor’s criticality to your operations.
3. Define incident priority tiers and response SLAs — Create 3–4 priority tiers (P1: Critical, P2: High, P3: Medium, P4: Low) with distinct response and resolution SLAs for each. Ensure P1 SLAs are achievable and clearly defined.
4. Set meaningful service credit levels — Service credits are the primary enforcement mechanism. Credits should be financially meaningful — 5–25% of monthly service fees per breach — but not so punitive that the vendor treats the SLA as a risk to avoid.
5. Embed the SLA within the vendor contract as an exhibit — The SLA should be executed as an exhibit or schedule to the main vendor contract — not as a standalone document. This ensures the remedy and enforcement provisions of the main contract apply.

Frequently Asked Questions

What is an SLA in a vendor contract?

An SLA (Service Level Agreement) is a contractual commitment defining the minimum performance standards a vendor must meet — including uptime, response times, and quality metrics — along with the consequences for failing to meet them.

What is a good uptime SLA for a SaaS vendor?

For mission-critical SaaS tools, target 99.9% uptime (8.7 hours downtime/year) as a minimum. For business-critical systems, negotiate 99.95% or higher. Ensure planned maintenance is defined and excluded appropriately.

What are service credits?

Service credits are financial remedies (typically 5–25% of monthly fees) triggered when a vendor fails to meet SLA commitments. They are not penalties but partial fee reductions reflecting the reduced service value received.

What is the difference between response time and resolution time in an SLA?

Response time is the time between incident report and vendor acknowledgement. Resolution time is the time between incident report and full service restoration. Both should be defined per priority tier in the SLA.

Can SLA terms be renegotiated mid-contract?

Yes, SLA terms can be amended if both parties agree and the amendment is executed in writing per the contract’s amendment process. Significant changes in service scope or vendor capabilities often warrant SLA renegotiation.
