Billing FAQ

Overview

Vapi uses a credit-based billing system where credits serve as the platform’s currency. Every billable action, including making calls and purchasing add-ons, requires credits. One credit equals one US dollar ($1 = 1 credit).

Each new trial account receives 10 complimentary credits in their wallet to help you get started. These credits can be used for making calls, but not purchasing add-ons.

To continue using Vapi after your trial credits are depleted, you’ll need to:

Add your payment details
Purchase additional credits
Your wallet will then be upgraded to pay-as-you-go status.

Your wallet will be marked as frozen while your credit balance is negative. Frozen wallets are unable to make calls or purchase add-ons.

What is auto-reload?

Auto-reload is a billing mechanism in which Vapi will automatically top up your credits when it hits a certain threshold. It can be enabled through the billing page and we highly recommend enabling it to prevent billing-related operational issues.

Auto-reload amounts must be at least $10. We recommend setting a threshold above $0.

Enabling auto-reload through the Vapi dashboard.

What are add-ons?

Add-ons are platform enhancements that you may purchase. They are purchased through the billing add-ons page.

The following add-ons are currently available:

Add-on	Price (credits / month)	Description
Phone Numbers	2	Twilio phone numbers for your calls
Reserved Concurrency Lines	10	Guaranteed capacity for concurrent calls
HIPAA Compliance	1,000	HIPAA Compliance and a BAA agreement
Slack Support	5,000	Priority support via dedicated Slack channel

Here’s how the billing works:

You’ll be charged a prorated amount for the remainder of the current billing cycle when you first purchase an add-on
Subsequently, you’ll be billed the full amount at the start of each billing cycle (the 1st of each month)
If you cancel an add-on, you’ll receive a prorated refund for the unused portion of the billing cycle.
Add-ons can be cancelled at any time through the billing page

If your wallet is frozen at the time of billing, all add-ons will be automatically cancelled. You’ll need to repurchase them once your wallet is reactivated.

How do I download invoices for my credit purchases?

You may download invoices within the billing page.

Find the relevant credit purchase within the payment history table, and click on Download Invoice. You may then optionally choose to fill in extra details which will be reflected within the Invoice.
