Billing Status for PDF Services API via AWS Marketplace

We have been using the PDF Services API to convert MS Office files into PDFs for over a year. We subscribed through AWS Marketplace, and the service has been working without any issues.

However, we’ve noticed that we have not been billed at all during this time, even though in some months we have made more than 500 API calls. This seems unusual, so we’re wondering if there might be any issue with billing or with the data integration between the service and AWS.

Could someone from the Adobe team check if everything is configured correctly on their side?
