Why Teams Choose Centerfy PRO

Hidden costs behind BYOK model

Synthflow's Starter plan is $29/month for 50 minutes. But the BYOK model means separate bills to OpenAI, ElevenLabs, Deepgram, and Twilio. Real all-in cost: $0.15-$0.37/min — up to 4x Centerfy PRO's $0.085/min.

Agency white-label costs $2,000/month

Synthflow's white-label plan is $2,000/month before BYOK usage fees. Centerfy PRO white-label starts at $497/month with no third-party dependencies.

No built-in CRM or pipeline management

Synthflow is voice infrastructure. No contact database, no deal stages, no pipeline tracking. Centerfy PRO includes a native CRM and pipeline manager.

Voice-only with no omnichannel

Synthflow handles phone calls only. No SMS, chat, email follow-up, or web chat widgets. Centerfy PRO covers voice, chat, and automation in one platform.

Users report instability at scale

G2 and independent reviews note Synthflow agents hallucinate, eat unused minutes, and behave inconsistently. Centerfy PRO is purpose-built for reliability.

Costs accelerate unpredictably

Synthflow bills per minute on platform plus BYOK costs from multiple vendors simultaneously. Centerfy PRO consolidates everything into one predictable rate.
