Why an internal SLA is different from the marketplace's external one
Each marketplace's own response-time requirement (see Customer Service Expectations by Marketplace) is the external floor you must meet to stay in good standing. An internal SLA is a standard you set for yourself or your team that's typically tighter than the platform's minimum, and that also covers things the platform's own metric doesn't — like resolution time (not just first response) and issue-specific handling targets. Setting your own tighter internal bar gives you a buffer before you're ever at risk of missing the external requirement, and gives a support team a concrete, specific target instead of a vague "respond quickly" expectation.
The template structure
Response-time tier, by issue type. Not every message deserves the same urgency — a template with tiers by issue type is more useful than one flat number:
| Issue type | Target first-response time | Target resolution time |
|---|---|---|
| Order status / general question | Same business day | Same interaction |
| Shipping delay complaint | Within a few hours | Within 1 business day |
| Damaged / wrong item | Within a few hours | Within 1-2 business days |
| Return / refund request | Within your platform's required window | Within 2-3 business days |
| Dispute or escalated complaint | As fast as possible, same day | Case-by-case, tracked to close |
Fill in your own specific numbers per tier — the point of the template is the structure (tiered by urgency and by first-response and resolution separately), not these illustrative figures.
Coverage hours and after-hours handling. State explicitly what hours the SLA applies to, and what (if anything) happens outside those hours — an autoresponder acknowledging receipt with a stated next-business-day follow-up is a common, reasonable middle ground for a small team that can't staff messages around the clock.
Escalation triggers. A specific list of situations that bypass the normal tier and go straight to you or a senior team member — a dispute threat, a suspected fraud pattern, or anything referencing an account health or policy issue.
Ownership and accountability. Who is responsible for monitoring the metric itself (checking that the team is actually hitting the stated targets), and how often that gets reviewed.
Worked example of filling it in
A solo seller handling everything themselves might set: same-business-day first response on everything, tighter same-day resolution targets for damage/wrong-item cases specifically (since those most directly risk a negative review), and a rule that anything from a clearly frustrated buyer gets handled before routine questions regardless of arrival order. As that seller hires their first support contractor, the same table becomes the actual training document and performance standard for that hire, with the escalation triggers row telling the contractor exactly when to loop the owner in rather than deciding alone.
Using it for accountability, not just documentation
An SLA that's written down but never checked against real performance doesn't accomplish much beyond looking organized. Pair the template with a simple recurring check — weekly is common for a growing team — comparing actual response and resolution times against the stated targets, and treat a consistent miss on a given tier as a signal to investigate (workload too high for current staffing, a specific person needing coaching, or a target that was set unrealistically tight) rather than letting the gap persist unaddressed.
Keeping the internal SLA ahead of the external requirement
Revisit your internal targets whenever a marketplace tightens its own external requirement (see Customer Service Expectations by Marketplace) — the point of setting an internal bar tighter than the external one is the buffer it gives you, and that buffer erodes if the external requirement moves and your internal target doesn't move with it.
