Synthflow Concurrency Ceiling

Synthflow's enterprise contract starts at $30,000 annually, but final pricing is scoped around call volume, concurrency, telephony setup, integrations, security needs, and launch support. Concurrency, not total minutes, is the number that decides whether an agency retainer holds its margin. Picture a mid-market healthcare client with 40 simultaneous peak-hour calls: the agency's Synthflow Inbound Voice Starter at $51250/mo carries 60h setup plus 10h/mo, so every concurrency tier the client crosses reopens the contract and the delivery estimate. Agencies that quote a flat retainer before mapping peak concurrency end up absorbing the difference in custom routing, escalation paths, and fallback logic. Map the client's busiest hour first, price the tier above it, and treat added concurrency as a change order rather than a favor.
