Resolution Ceiling

Resolution Ceiling is the share of inbound contacts a platform closes without a human, and it sets the ceiling on what an agency can charge for a managed support retainer. Vendors publish wide bands: Nectar Desk's AI Voice Bot resolves 40-65% of calls autonomously, while Glassix routes conversations to AI agents by default and escalates only exceptions. The gap between those two numbers is not a product defect, it is the agency's pricing variable. Every point of resolution you add through custom intent trees, vertical vocabulary, and escalation rules converts agent hours into margin. The ceiling also moves: agentic control failures show autonomous systems acting outside intended boundaries, so a resolution rate without a containment policy is a liability, not a saving. Agencies that document resolution rate by intent, with a named human owner for each escalation path, defend the retainer. Agencies that quote a vendor's headline percentage without a measured baseline get repriced at renewal.
