Honest comparison
Heyfield vs Synthflow — A Synthflow Alternative for Home-Service Trades
Synthflow is a generalist voice AI platform — you build your own AI phone agent from scratch, wire it to your data, and deploy it for any use case. Heyfield is the opposite philosophy: a turn-key AI receptionist purpose-built for home-service trades, with the intake script, dispatch routing, and calendar integration already wired. Synthflow is more flexible. Heyfield is faster to deploy and tuned for the exact use case home-service owners need.

FAQs
- Can't I just configure Synthflow to do what Heyfield does?
- Technically yes. Practically you'd write the trade-specific intake script, configure dispatch routing, integrate Google Calendar, set up SMS notifications, tune the voice, and maintain it. That's days of work plus ongoing prompt engineering. Heyfield does this out of the box.
- What if I want to customize Heyfield beyond defaults?
- Heyfield allows configuring greetings, business hours, transfer rules, and trade-specific qualifying questions through the dashboard. If you need custom voice flows or non-standard integrations, Synthflow gives more flexibility at the cost of build time.
- What does the all-in cost comparison look like?
- Synthflow Starter $30 + your time. If your time is worth $100/hr and configuration takes 6 hours, that's $630 first-month cost. Heyfield is $49 first-month, all-in. After year one the costs converge depending on usage tier.
- Can I switch from Heyfield to Synthflow later if I outgrow it?
- Yes. Heyfield doesn't lock you in with annual contracts. If you eventually want full custom control over voice flows or expand into non-trade verticals, switching is a 30-day migration. Most home-service shops never reach that point.
