Sonant vs Presto Voice

The two products share only the surface layer: an AI voice agent answers a phone. Everything below that diverges.

Presto Voice is built for one physical moment — the drive-thru speaker post. It takes the order, then continuously offers add-ons and specials, which is the whole commercial thesis: vendor-published figures claim up to 95% non-intervention, up to 88% upsell offer rate, and up to 6% monthly incremental revenue. A spectrum of Voice AI models adapts to multi-brand menus and speech patterns, and installation is designed to happen at scale across live lanes without breaking throughput. Toast integration (Sept 2026) adds POS reach.

Sonant is built for the insurance desk. It answers on the first ring 24/7, recognizes callers by phone match with DOB or ZIP verification, and pulls policy, coverage, renewal date, and deductible from the AMS mid-call. It handles quote, renewal, billing, claim, and certificate requests, does mid-call language switching across English, Spanish, Portuguese, French, and Korean, and warm-transfers complex calls with context. Critically, it writes a structured, auto-titled activity back into the AMS before the caller hangs up — something Presto has no equivalent for.

Both vendors are quote-only, so the honest answer is that you cannot compare list prices — there aren't any published. That's a deliberate enterprise motion in both cases, and it means the real comparison is procurement effort versus deal size.

Presto's not-for list is explicit: buyers who insist on published self-serve pricing before taking a call are out of scope, and single-location operators can't justify the managed deployment overhead. Expect a franchise-level contract covering install across sites, with ROI reporting across non-intervention, upsell, and revenue lift as the justification. The Toast Partner Ecosystem listing (Sept 2026) may simplify commercial packaging for Toast POS franchise groups, but no pricing is stated.

Sonant is also contact-sales, but its qualification floor is lower and clearly stated: very small agencies handling fewer than five calls a day are not a fit, and businesses outside insurance are out entirely. For everyone else, the cost case is receptionist overhead offset by 24/7 first-ring coverage — a headcount comparison, not a software comparison. Neither vendor publishes tiers, so neither gets a pricing win. Ask both for per-seat or per-location economics.
