Service Level Agreement
Our commitment to your uptime

Service credit calculation
If we miss the uptime target for your plan in a calendar month, you’re entitled to a service credit applied to the following month’s invoice:
- 0.1% to 1.0% below target — 10% credit
- 1.0% to 2.0% below target — 25% credit
- More than 2.0% below target — 50% credit
Credits are not issued automatically. Email billing@callsathi.comwithin 30 days of the incident with the affected month and we’ll reconcile.
What’s not covered
- Scheduled maintenance windows announced at least 7 days in advance.
- Issues caused by third-party telephony / WhatsApp / payment providers when the upstream service is itself reporting an outage.
- Customer-side misconfiguration (wrong API key, mis-routed DNS, deleted phone number, revoked Meta access token).
- Force majeure events: natural disasters, government action, war, cyber-warfare campaigns.
- Free trials, paid trials, and Pay-As-You-Go usage do not carry uptime SLAs.
