Post-engagement support and maintenance beyond the 90-day warranty is available under a separate Support & Maintenance Agreement (SMA) billed monthly, covering bug fixes, minor enhancements, and priority access to Zeroth Agents engineers.

The SMA is optional but recommended for production deployments. It provides a dedicated support contact, guaranteed response SLAs, and a monthly hours allocation for minor change requests. SMA pricing is 15-20% of the original SOW value annually.
