Billing Overview
The Billing tab allows you to manage payments, track expenses, and download invoices. Here’s what you can do:- Payment Management: We use Stripe for secure and reliable payment processing. You can update your payment methods by clicking on the “Change payment methods” button.
- Billing History: Review your monthly expenses, including detailed cost breakdowns by category (e.g., Voice Infra, LLM).
- Invoices: Easily download invoices by clicking the “Invoice” button next to the respective period.
- Current Charges: View ongoing costs for the current billing period, including itemized amounts and usage details.
Retell uses post-usage billing, not a prepaid credit balance. You are charged at the end of each billing period based on actual usage on the payment method you have on file — there is no manual top-up or auto-recharge to configure. Make sure a valid payment method is added (see Add payment methods) to avoid service interruptions. If a charge fails, follow Handle failed payments.
