Per-Second Billing for AI Calls: What You Actually Pay

17 Oct 2026 · 5 min read · Omixo AI

You pay for connected time, by the second

Instead of a fixed monthly receptionist salary, Omixo bills AI calls per second of connected talk-time from a prepaid wallet. Missed or unanswered attempts are not charged like connected minutes, and there is no lock-in — you top up and use as you go.

What makes up your bill

  • AI voice: per-second connected talk-time (AI calls from about ₹6/min)
  • WhatsApp / website chat: per AI reply
  • A monthly virtual number rental
  • Two concurrent calls free to start

Why per-second matters

Per-minute rounding quietly inflates short calls — a 20-second call billed as a full minute is 3× the real cost. Per-second billing means you pay for exactly what you use. The usual unit of AI cost is the token; see the Muzztech AI glossary for the plain-English basics.

FAQs

Is there a setup fee or lock-in?+

No lock-in. You start with a prepaid wallet and a monthly number; you only pay for connected time and AI replies.
