0/7 checks complete
  1. Confirm the tool meets every must-have workflow and stakeholder requirement.

    Review starting point: High-volume, repeatable call intents; Teams with staffed escalation; Businesses able to audit recordings and outcomes

  2. Run the same representative work you would use in production; do not score a polished demo.

    Review starting point: Complete three to five representative tasks with known acceptable outcomes and compare them with your current process.

  3. Calculate the effective cost per accepted result, including usage, review, corrections, and required add-ons.

    Review starting point: Voice-agent cost depends on plan, minutes, telephony, models, integrations, and concurrency. Verify current rates, included usage, overages, numbers, and contract terms on the official pricing page.

  4. Define an acceptance threshold, test known answers and edge cases, and record every correction.

    Review starting point: Editorial quality signals: features 0.0/5. Validate these signals in your own work.

  5. Verify what data enters the product, who can access it, how long it is retained, and whether it trains models.

    Review starting point: Use approved low-risk data first. Check roles, consent, deletion, subprocessors, model-training settings, and the contract—not only the marketing page.

  6. Test the real handoffs, permissions, failure states, and export path your team depends on.

    Review starting point: Telephony, Calendars, CRM, Webhooks, Zapier, Make

  7. Record training, governance, reliability, accessibility, ownership, and change-management risks before rollout.

    Review starting point: Per-minute economics can hide failed-call cost; Consent and recording rules vary by jurisdiction; Latency or weak escalation can damage high-stakes calls

FAQs

What does Synthflow do?

It helps teams build AI voice agents that answer or place calls, collect information, book appointments, update systems, and transfer to people.

How much does Synthflow cost?

Total cost depends on the plan and voice usage. Confirm included minutes, overages, telephony, model, number, concurrency, and integration charges before purchase.

Can a Synthflow agent replace a call team?

It can cover narrow repeatable intents, but exceptions, distress, disputes, accessibility needs, and high-value conversations require reliable human escalation.

How should a voice agent be tested?

Use approved calls across accents, noise, interruptions, silence, objections, transfer failures, opt-outs, and adversarial prompts; score resolved outcomes and harm, not just answer rate.
