Setup Complete!

Cost data will be available within 24-48 hours. Paygent will automatically sync your GCP billing data daily.

Troubleshooting

Invalid JSON file

Ensure you downloaded the service account key in JSON format (not P12). The file should start with {.

Permission denied errors

Verify the service account has all three required BigQuery roles. Check that the billing export is in the same project as the service account.

Dataset or table not found

Double-check the dataset and table names match exactly (case-sensitive). Ensure BigQuery export is enabled and has generated at least one export.

No cost data appearing

GCP billing exports are generated daily. Wait 24-48 hours after setup. Ensure your GCP project has actual usage to report.
