Service Level Agreement (SLA)
A Service Level Agreement (SLA) is a contractual commitment between a vendor and customer that defines the maximum acceptable response and resolution times for support tickets by priority level. SLA breaches — where actual resolution time exceeds the committed window — trigger financial penalties including service credits, pro-rated refunds, or contract termination clauses. For B2B SaaS companies, SLA compliance is a direct revenue protection mechanism.
Why it matters for B2B support
Enterprise B2B SLAs typically define 3–4 priority tiers: P1 (production down, 15–30 min response, 4 hr resolution), P2 (major feature broken, 1 hr response, 8 hr resolution), P3 (degraded performance, 4 hr response, 24 hr resolution), and P4 (general questions, 8 hr response, 72 hr resolution). SLA breach economics are severe: a single P1 breach for a $200K/year enterprise customer can cost $10K–$50K in credits. At 5% monthly churn risk per breach, a single missed SLA on a $1M ARR account represents $50K in expected annual revenue loss.

How Altor helps
Altor helps meet SLA targets by starting investigation the moment a ticket arrives, rather than when an agent picks it up. This eliminates the queue-to-investigation gap that causes most SLA breaches.
FAQ
What is an SLA in customer support?
An SLA in customer support is a contractual promise that defines maximum response and resolution times. Tier 1 (P1) issues — production outages — typically require a 15–30 minute first response and 4-hour resolution. Breaching these triggers financial penalties and damages customer trust.
What are typical B2B SaaS SLA targets?
P1: 15 min response, 4 hr resolution. P2: 1 hr response, 8 hr resolution. P3: 4 hr response, 24 hr resolution. P4: 8 hr response, 72 hr resolution.
What happens when you breach an SLA?
Contractually: service credits (typically 5–25% of monthly fee per breach). Practically: eroded customer trust, increased churn risk, and escalation to executive sponsors.
How do you track SLA compliance?
SLA compliance is tracked by measuring time-to-first-response and time-to-resolution per ticket against the contracted tier thresholds. Modern helpdesks (Zendesk, Freshdesk, Intercom) have built-in SLA timers. The operational challenge is not tracking — it's investigation speed. The 20–45 minute manual investigation window is where most P1 SLAs are lost.
What is the difference between SLA and SLO?
An SLA is a contractual commitment with financial penalties. An SLO (Service Level Objective) is an internal target, often more aggressive than the contractual SLA. For example, your SLA might commit to 4-hour P1 resolution while your internal SLO targets 2 hours. SLOs give you buffer to absorb investigation delays without breaching the customer-facing SLA.
