Compare the scope of each rate before comparing the number. All amounts below are USD.

| What matters | APIFleet | Synthflow |
|---|---|---|
| Starting point | $0.03 per connected AI minute Platform fee, billed per second | From $30,000 / year Published enterprise contract floor |
| Payment model | Prepaid usage. $10 minimum top-up. No monthly subscription or free credits. | Enterprise contracts depend on volume, concurrency, integrations and support requirements. |
| Cost scope | AI providers and carrier charges are additional. Customer-owned keys are paid directly to providers. | The current offer includes implementation, testing, training and launch support. Confirm the complete scope in a proposal. |
| Working style | Configurable assistants, tools, knowledge, browser tests, simulations and call logs. | Enterprise telephony and business integrations form part of a managed rollout. |
Compare the delivery model as well as the software.
This is not a simple per-minute contest. A managed enterprise project can include work that your own engineers would need to do on a developer platform. Compare your internal implementation budget, rollout responsibilities and contract requirements alongside usage.
When Synthflow may fit
Evaluate Synthflow when you need an enterprise implementation engagement and its proposed scope fits your procurement and operations requirements.
When APIFleet may fit
Evaluate APIFleet when your team wants to configure and integrate agents itself, fund usage from $10 and avoid an annual platform commitment.
APIFleet currently limits new workspace access. Existing users can sign in; contact us about a new project. Carrier accounts, standalone previews, file transcription and simulation caller/judge models require customer-owned credentials.
Two workloads to price explicitly
These hypothetical examples assume exactly 1,000 or 10,000 connected AI minutes. They calculate APIFleet’s platform portion only; model, speech, carrier, numbers and any other service charges must be added.
| Workload | APIFleet platform arithmetic | Synthflow estimate |
|---|---|---|
| Pilot: 1,000 minutes | 1,000 × $0.03 = $30.00 | Apply the vendor’s published or quoted terms to the same provider stack and duration. |
| Operation: 10,000 minutes | 10,000 × $0.03 = $300.00 | Include subscriptions, allowances, overages, rounding and implementation work when applicable. |
A bundled vendor rate cannot be compared directly to the APIFleet platform portion. We do not infer Synthflow’s concurrency or seat limits from a minute rate; confirm them for your planned workload.
Run a one-assistant switching pilot
Before switching from Synthflow, recreate one assistant, replay its tool requests, test interruptions and transfers, then move one controlled route with a written rollback. Use the voice-agent migration checklist and conversation test plan with the vendor-specific checks below.
What to test before switching
- Write down who owns integrations, testing and launch support.
- Request a quote at your expected concurrency and call volume.
- Confirm contractual requirements before assuming a self-serve platform can replace them.
There is no universal one-click import. Map prompts, tools, credentials and routing explicitly, then run controlled calls. Our gradual migration guide gives you a sequence with a rollback boundary.
