Ad-hoc support works well when IT problems are rare and low-stakes. The model breaks down quietly, not dramatically — you don't usually notice the exact moment you've outgrown it, you just notice that things feel harder than they should. These are the five signs we see most often in businesses that are ready for a monthly SLA instead.
You're calling for the same kind of issue repeatedly
Recurring disk space warnings, the same service crashing monthly, a backup job that "sometimes" fails — under ad-hoc support, each call is billed and resolved in isolation. Nobody's incentivised to fix the root cause, because the root cause isn't what you're paying for. An SLA includes proactive monitoring specifically to catch and resolve these patterns before they're a call at all.
You don't know if your backups actually work
Ad-hoc engagements rarely include scheduled restore testing — there's no billable trigger for "check that last month's backup would actually restore." If you can't answer "when did we last successfully test a restore," that's symptomatic of needing ongoing, scheduled oversight rather than reactive call-outs.
Downtime costs more than a monthly retainer would
Once an hour of downtime costs your business more than a month of proactive monitoring and support, the economics flip. Most businesses cross this threshold well before they notice it, because the cost of downtime is diffuse (lost productivity, frustrated clients) while the cost of an SLA is one visible line item.
You have more than 10 servers or endpoints to keep track of
Below a certain scale, one person can mentally track "what's running where." Past it, you need actual monitoring tooling, alerting thresholds, and someone watching dashboards — none of which fits naturally into a reactive, call-when-broken relationship.
Security and compliance are now actually relevant to your business
Once you're handling client data with real sensitivity, processing payments, or simply large enough that a breach would be reputationally serious, "we'll fix it when it breaks" is no longer an adequate security posture. That requires ongoing patching discipline, monitoring, and policy — structurally an SLA function, not a callout function.
What a good SLA should actually include
- Defined response times by severity, not "we'll get to it"
- Included server monitoring — not an upsell, a baseline
- A fixed number of support hours per month, with clear rates for anything beyond that
- Regular reporting so you can see what's actually being managed on your behalf
If a provider can't tell you exactly what's included in their SLA in one sentence, that's worth questioning before you sign anything.
