Billing Overview
Voxifi uses a two-part billing model: a monthly subscription for platform access, plus a prepaid usage balance for call costs.
How Billing Works
Monthly Subscription
Choose a plan that fits your scale. Your subscription determines your limits and is billed monthly via Stripe.
| Plan | Monthly | Lines | AI Assistants | Phone Numbers |
|---|---|---|---|---|
| Starter | $100 | 1 | 1 | 1 included |
| Growth | $250 | 5 | 3 | 1 included |
| Scale | $500 | 10 | 10 | 1 included |
Additional phone numbers can be added to any plan for $10/month each.
Prepaid Usage Balance
On top of your subscription, call costs are deducted from a prepaid balance:
- Add funds to your balance
- Make calls
- Costs are deducted after each call completes
- Top up when needed — or enable Auto Top-up
This means you always know what you're spending on calls, with no surprise end-of-month bills.
Cost Structure
Subscription
Fixed monthly fee based on your plan. Billed automatically via your saved payment method.
Call Costs
Each call is charged based on:
- Voice — per-minute charge for the phone call
- LLM — language model usage for conversation
- Transcription — speech-to-text processing
The exact cost for each call is visible in call history after it completes.
Phone Number Costs
- 1 phone number included with every plan
- Additional numbers: $10.00/month each
