Why this memo.
Housecall Pro serves the segment ServiceTitan and FieldEdge consider too small. That segment has scaled. The 18-pro HVAC operator running Housecall Pro and pulling $4M-$8M in revenue is increasingly common, and the operational dynamics at that scale look more like a small platform than a large solo. AI is becoming relevant.
This memo describes what we'd commission for that operator. The build cycle is shorter than the ServiceTitan playbook because Housecall Pro's API surface is more constrained, which actually accelerates scoping discipline.
The Housecall Pro surface area we touch.
Housecall Pro exposes a REST API with coverage of customers, jobs, estimates, invoices, and pros (technicians). OAuth2 authentication. Webhooks for job lifecycle events. The API is sufficient for the workflows below; we read/write through it rather than at the database level.
Workflow I: 24/7 AI receptionist into Housecall Pro jobs.
Most Housecall Pro operators we audit run 8-22% call abandonment, especially after-hours and weekend. The AI receptionist answers, qualifies, books, writes the job into Housecall Pro with the correct service line, customer record, and notes. Morning dispatcher sees the overnight bookings ready to schedule.
Recovery: at typical $200-$600 average ticket, recovering even 50% of abandonments is $80K-$280K annual revenue at the median 12-pro operator scale.
Workflow II: Multi-pro routing coordination.
Housecall Pro's native dispatch is solid for single-trade operators. Multi-trade operators (HVAC + plumbing + electrical under one roof) typically dispatch by hand, optimizing within trade and missing cross-trade opportunities. The AI coordinates across all pros for the day, surfaces the cross-trade-optimal route to the dispatcher.
Workflow III: Technician priming on the truck roll.
The AI reads customer + job history from Housecall Pro, drafts the priming notes for the technician's mobile, surfaces upsell opportunities the customer is likely to convert on. The dispatcher does not have to brief each tech; the AI does.
What we don't build.
We do not replace Housecall Pro. We do not build invoicing, payments, or scheduling competing with the platform. The leverage is in the call-handling and dispatch layer above Housecall Pro, plus retention/membership conversion in the field.
