Then the Recovery Planner tab compares your options — AI receptionist, answering service, office hire — side by side on cost, recovered revenue, and payback multiple.

- Recovery Planner compares three fix options with your own assumptions
- Built for any trade: plumbing, HVAC, electrical, remodeling, landscaping
