### Answer The small discrepancy between your exported CSV total ($45.21) and your invoice ($45.24) is likely due to how Retell handles billing calculations: 1. **Rounding on short calls**: Retell rounds very short calls (under 10 seconds) up to 10 seconds for billing purposes. [(1) ]() [(2) ]() 2. **Per-second vs. per-minute display**: Dashboard pricing is shown per minute, but actual billing is calculated per second. This can cause slight differences when you manually sum exported data. 3. **CSV export filtering**: The CSV export may filter out or round certain call types differently than the actual billing system—things like ringing time, incomplete calls, or calls that never fully connected may be handled differently. The $0.03 difference you're seeing is consistent with these rounding behaviors across your call volume. If you need clarification on the specific charges, you can reach out to Retell AI support at support@retellai.com with your organization ID, and they can review your billing details.
