Postpaid Billing Usage Guide
Enterprise Only
Postpaid billing is available exclusively for Enterprise plan customers with a separate agreement. To inquire, please contact us.
How It Works
Postpaid billing allows you to use the API freely without pre-purchasing credits. Usage is tracked in real time and settled on a monthly cycle.
- Use the API — Make API calls as needed throughout the month. No credit balance required.
- Monthly aggregation — At the end of each billing cycle, your total usage (STT seconds, Pronunciation Feedback seconds) is aggregated.
- Invoice issuance — An itemized invoice is generated via Stripe, detailing usage by service type and total cost.
- Automatic payment — The invoice amount is automatically charged to your registered payment method.
Billing Cycle
- Your billing cycle is based on a designated billing day set during contract setup (e.g., the 1st or 15th of each month).
- Usage from the previous period is aggregated and invoiced on each billing day.
- Invoices are available in the API Console under Billing.
Payment Method
A credit card must be registered in advance. You can add or update your payment method in the API Console under Billing → Payment Method.
Invoice Details
Each invoice includes:
- Breakdown of usage by service (STT, Pronunciation Feedback)
- Total seconds processed per service
- Unit price applied
- Total amount due
- Stripe hosted invoice link for download/receipt
Advantages
- No service interruption — API calls are never blocked due to credit exhaustion.
