What you'll accomplish
By the end of this guide, you'll have an AI system that answers your business calls when you're unavailable, collects the customer's name, address, and job description, and either books them directly on your calendar or sends you a detailed message — so you never lose a job to a competitor because your phone went unanswered.
What you'll need
- Housecall Pro account (or a compatible FSM app)
- A business phone number (can be your current number, set up through Google Voice or your carrier)
- Time needed: 45–60 minutes for initial setup
- Cost: Housecall Pro's answering feature is included on some plans; third-party AI answering services (Synthflow, AgentZap) run $50–150/month for basic plans
How-To Guide: Set Up an AI Phone Agent to Answer Calls While You're on a Job
Step 1: Understand Your Options
You have two paths:
Option A — Housecall Pro's built-in call answering (simpler, if your plan includes it) Best if you're already on Housecall Pro Essentials or above. Check by going to Settings → Phone or Communications in your Housecall Pro account.
Option B — A dedicated AI answering service (more capable, separate subscription) Tools like Synthflow (synthflow.ai) or AgentZap (agentzap.ai) connect to Housecall Pro, ServiceTitan, or work standalone. They answer calls, qualify leads, and can book appointments directly. This guide uses the general approach that works with both.
