- You want hour-by-hour human flexibility. Smith.ai lets you scale up live agents during peak windows.
- Your business is non-trade professional services. Smith.ai's training is built around law firms, agencies, and similar.
Where Columa is the better choice

- You have bursty call volume. Storms, heat waves, freezing snaps. Columa answers fifty calls in parallel.
- You want predictable monthly pricing. Columa's overage rates ($0.30/min after 150 min, $0.07/chat after 300) are dramatically lower than Smith.ai's per-call billing past your included tier.

Pricing comparison
Smith.ai's published pricing starts at ~$292/month for 30 calls. Beyond that, per-call. A modest service business doing 200 calls/month is looking at $700–$1,200/month.
Columa's pricing tiers, as published on columa.co:
- Chat + Voice — $149/mo. AI chat on your website + AI voice on your line; 150 chats + 50 voice min/mo.
- Concierge — $349/mo. Adds booking + a unified inbox; 300 chats and 150 voice min/mo.
- Full Front Desk Pro — $499/mo (most popular). Adds proposals, e-sign agreements, and invoicing sync (QuickBooks or Wave); 500 chats and 400 voice min/mo.
Guided Setup is optional at checkout ($299–$499 one-time, by tier). For a service business doing 200+ calls a month, Columa is typically 40–60% less than Smith.ai with the equivalent feature set.
