Key Differences
1. AI at a flat, public price vs. human agents at a per-minute quote
Callbook is an AI receptionist with transparent, published pricing — $79/mo with 250 included minutes. You know your bill before you sign up.
Nexa staffs live human receptionists and bills per minute on a quote-based plan with a monthly minimum, and rounds calls up in 30- or 60-second increments — so the real cost depends on call volume and length.
2. Trades-built workflows vs. general-purpose answering
Built for home-service and trades businesses — Callbook asks the right questions for your trade, triages emergencies, and books the job into Jobber, Housecall Pro, or ServiceTitan.
Nexa is a general answering service used across many industries, with trained agents following your custom scripts and integrating with common booking systems — broad, but not trade-specific.
3. Where each one shines
Best when you want predictable cost and an AI that answers every call, qualifies it, and books it 24/7 without per-minute surprises.
Best when you specifically want trained human agents handling nuanced calls, live dispatching, and after-call work, and are comfortable with quote-based, per-minute billing.
