When subscribing to enterprise software, an SLA is an agreement that defines the service levels a provider commits to, how they are measured, and the provider’s responsibilities if those levels are not met. To evaluate an SLA, check its coverage, support times, and remedies rather than looking only at the uptime percentage.
According to Vietnix’s explanation of SLAs, these agreements typically include performance targets, monitoring, incident handling procedures, and consequences for breaches. For software buyers, the key is to turn those commitments into questions whose answers can be verified.
1. Identify What Is Covered
A platform may remain accessible even when a critical function is not working. Ask whether the SLA applies to the entire service or only certain components.
For example, when implementing CRM to manage customers and sales, businesses should check whether creating customer records, updating opportunities, and synchronizing data are covered by the commitments.
Clearly document the processes that cannot be interrupted before comparing providers. A high uptime level may not meet your needs if essential functions are excluded.
2. Distinguish Between Different Time Commitments
“Fast response” does not mean “fast resolution.” When reading the contract, distinguish between:
Metric | What to Clarify |
|---|---|
Response time | How long before support staff pick up the request and respond? |
Restoration time | How long before the service is operational again, even through a temporary workaround? |
Resolution time | How long before the cause of the incident is addressed? |
Update frequency | How are customers informed of progress while they wait? |
Also check whether support is available outside business hours. Does the clock start when a request is submitted or acknowledged, or does it run only during business hours?
3. Review Uptime Calculations and Exclusions
Uptime is the percentage of time a service is available during the measurement period. For illustration, if it is calculated over an entire 30-day month with no time excluded, 99.9% uptime corresponds to approximately 43.2 minutes of unavailability.
However, the contract may specify a different calculation method. Check:
Is the measurement period a month or a year?
Is scheduled maintenance excluded from the calculation?
How is a loss of connectivity on the customer’s side determined?
Which tools record incidents, and can customers view the reports?
With ERP connecting processes across departments, the timing of an interruption also matters: an incident while finalizing orders or handling warehouse operations may have a greater impact than one outside business hours.
4. Check Your Entitlements in the Event of a Breach
Do not assume an SLA breach will result in a refund. Depending on the contract, the remedy may be service credits—amounts applied to offset service fees.
Read the conditions for claiming credits, the submission deadline, the evidence required, and the maximum amount. Also check your right to terminate the contract if breaches recur. Fee credits do not necessarily compensate for business losses.
5. Finalize Incident Handling Procedures Before Signing
Agree on the point of contact, severity levels, and escalation path for unresolved incidents. The business also needs someone internally to document the impact and record when incidents occur.
If you are still weighing ERP against CRM, first identify which processes the system will support. SLA requirements should reflect your actual level of reliance on the system, not a generic contract template.
Conclusion
A useful SLA must answer three questions: what is guaranteed, how it is measured, and what happens in the event of a breach. Clarifying these points before signing helps businesses assess service commitments against their operational needs.
Frequently Asked Questions
Is an SLA the Same as a KPI?
No. A KPI is a measure of performance, while an SLA is an agreement on service levels and the responsibilities of the parties involved. A metric may be used in both, but including it in an SLA requires a measurement method, a defined scope, and conditions for handling failures to meet it.
Is 99.9% Uptime Enough for Every Business?
There is no level that suits everyone. Consider the impact of interruptions, when the service is used, the ability to work with temporary arrangements, and the cost of a higher service commitment. Also check the exclusions in the uptime calculation.
What Should You Ask If the Provider Does Not Commit to a Resolution Time?
Ask about service restoration targets, temporary workarounds, update frequency, and escalation procedures. These help businesses plan their response even when the time needed for a complete fix cannot yet be determined.
