├── B: Redirect to value
└── Measure: Conversion rateROI and Payback (Realistic)
AI receptionist pays off when call volume and missed-call rate are high. The main drivers are:
- Calls/day and % missed after hours
- Average handle time per call
- Value per booking/lead and conversion from recovered calls
- % of calls the agent can automate end-to-end
- Integration scope (CRM/calendar/ERP)
Quick estimate:
Monthly benefit = (automated calls x minutes saved x cost/minute)
+ (recovered calls x conversion rate x avg order value)
- monthly fee
Payback = setup fee / monthly benefitTeams with 20+ calls/day often see payback in 1-2 months; lower volume usually takes longer. Actual results depend on volume, conversion, and integrations.
