How much does an AI voice agent really cost? The complete guide to optimizing your ROI

AI voice agents are revolutionizing customer relations and sales prospecting. But behind their effectiveness lies a crucial question: what is their real cost? At Volubile, we have designed a transparent, high-performance solution that is suitable for businesses of all sizes. Here's how to understand and control your investment.

Pay-as-you-go: flexibility without commitment

The pay-as-you-go model allows companies to pay only for what they actually consume. Unlike monthly subscriptions or per-seat plans, this model:

  • Eliminates unnecessary fixed costs.
  • Adapts to volume variations (seasonality, one-off campaigns, tests).
  • Facilitates experimentation without long-term commitment.

This solution is ideal for startups, SMEs, scale-ups, or pilot projects. Pay-as-you-go allows you to get started quickly without overinvesting.  

Per-second billing: accuracy and savings

Volubile bills calls by the second. You pay for what you use and nothing more. Advantages of per-second billing:

  • Cost optimization for short or frequent calls
  • Total transparency on consumption
  • Volume-based discounts

Volubile: pricing designed for performance

With Volubile, you benefit from clear and scalable pricing:

  • Conversation time: billed by the second, with sliding scale rates.
  • Advanced features: CRM integration, appointment scheduling, lead qualification.
  • Voice customization: tailor-made voice, tone adapted to your brand.
  • Analysis & reporting: detailed KPIs to track your performance.

Why does the cost vary depending on usage?

The price of an AI voice agent depends on several factors:

  • Call volume: the more calls you handle, the lower the unit cost.
  • Scenario complexity: an agent that qualifies leads costs more than a simple answering machine.
  • Business integrations: CRM, calendars, internal tools.

Volubile helps you tailor your voice agent to your objectives, without unnecessary additional costs.
