How to Write a WhatsApp SLA Policy for Your Support Team
Short answer
A WhatsApp SLA policy states how quickly you will respond and resolve conversations, by priority, during defined working hours. Set realistic first-response and resolution targets from your current data, define what counts as each priority level, add escalation steps, and use alerts to flag conversations before they breach.
SLAs turn “we reply quickly” into something you can measure and manage. On WhatsApp, where customers expect speed, a clear internal SLA is what keeps a shared inbox from turning into a race to whoever notices first.
What an SLA should cover
- Working hours and time zone. SLA clocks should normally run only during staffed hours.
- First response target by priority.
- Resolution target by priority.
- Priority definitions, so agents classify consistently.
- Escalation path when a target is at risk.
- Exclusions, such as customer delays or public holidays.
Define priorities
| Priority | Definition | Example |
|---|---|---|
| Urgent | Service down or customer blocked, or safety and financial risk | Cannot access account, payment taken twice |
| High | Significant issue with a workaround | Order delayed beyond promise |
| Normal | Standard question or request | How do I change my address? |
| Low | General enquiry or feedback | Feature suggestion |
Resolvenyx tickets use the same four levels (Low, Normal, High, Urgent), so the definitions map directly. See ticket management.
Set targets from real data
- Pull your current average and 90th-percentile first response and resolution times. See metrics.
- Set the first version of each target slightly better than your current 90th percentile, so it is achievable.
- Tighten gradually as processes and staffing improve.
- Set stricter targets for higher priorities, and keep them realistic.
Avoid copying another company’s numbers. The right target is one your team can hit about 90 to 95 percent of the time at your current staffing.
Escalation and alerts
- Warn the assignee when a conversation reaches about 75 percent of its target.
- Notify a team lead at 100 percent.
- Reassign automatically if the assignee is offline or over capacity. See assigning messages.
Resolvenyx supports SLA policies with response and resolution targets by priority and alerts before breaches. SLA policies are available from the Growth plan; see pricing.
Mind the WhatsApp-specific rules
On WhatsApp the 24-hour window is a hard limit. Your response SLA should be comfortably shorter than 24 hours, and any follow-up outside the window needs an approved template.
Review and communicate
- Review SLA performance monthly and adjust.
- Share the policy with the whole team.
- If you promise response times to customers, publish only what you can reliably meet.
Frequently asked questions
What is a good SLA for WhatsApp support?
There is no standard. Start from your own data, set a target you can meet most of the time, and tighten it as your team improves.
Should SLA clocks run outside working hours?
Usually not. Define business hours and time zone, and pause the clock outside them.
Do I need an SLA if I have a small team?
A simple SLA helps at any size because it defines what “on time” means and gives you something to improve against.
