Frequently Asked Questions (FAQs)
Is testing charged the same as live usage?
Yes. Playground runs are billed just like live sessions, so there are no surprises when you go live.
How is voice usage charged?
Voice agents are billed per minute — only while your AI is actively speaking or listening.
Are there any hidden fees?
None. No charges for uploading a knowledge base. No fees for concurrency, flows, intents, or usage limits. SigmaMind’s pricing is simple: you pay per message or voice minute — whether you’re testing in Playground or going live.
Is there a charge for concurrent users or active calls?
No concurrency fees. Whether 1 or 100 users are talking to your agent at once, the pricing stays the same. You scale. We don’t penalize.
Can I charge separately for different clients?
Yes. Create separate workspaces with individual usage tracking and billing for each client or project.
Can I choose my own models for calls or messages?
Yes. Use your preferred LLMs, voice engines, or SIP setup. Or choose SigmaMind defaults — it’s flexible.
What’s included in the platform fee?
Unlimited flows, analytics, app integrations, and workspace management — all included.
How do enterprise plans differ?
Enterprise customers get custom pricing, private deployments, advanced reporting, and dedicated support via Slack.
