Support plans often lead with response time as the headline number, but the right SLA isn’t automatically the fastest one available — it’s the one that matches what’s actually at stake if something breaks.
Start With What Downtime Actually Costs You
A system that directly generates revenue every hour it's up justifies a faster, more expensive SLA than an internal tool used a few times a week — quantify the real cost of an hour of downtime before shopping for response times.
Understand What "Response Time" Actually Guarantees
Response time is when someone acknowledges the issue, not necessarily when it's fixed — ask separately about typical resolution time for critical issues, since that's the number that actually matters.
Business Hours vs. 24/7 Coverage
24/7 coverage costs more and matters most for systems used around the clock or by customers in multiple time zones — for a purely internal, business-hours tool, it's often unnecessary expense.
Severity Tiers Matter More Than a Single Number
A well-structured SLA defines different response times for critical outages versus minor bugs — a single blanket response time either overspends on minor issues or underserves critical ones.
Match the SLA to the System, Not a Blanket Policy
Different systems within the same business often warrant different SLAs — the customer-facing checkout flow and an internal reporting tool don't need the same guarantee.
Frequently Asked Questions
What’s a reasonable response time for a small business?
For most small businesses, same-business-day response for non-critical issues and a few-hour response for critical ones is a reasonable, cost-effective baseline.
Can our SLA change as the business grows?
Yes — SLAs should be revisited periodically as systems become more business-critical or usage patterns change, not locked in permanently at the original signing.
