Thanks for the question. That's a use case we haven't considered yet, great feedback! As of today, we are using the Organization concept in AWS so "One CloufForecast.io account" == "One Master billing account in AWS". Your use case seems to be slightly different since it's multiple accounts across multiple clients. I would love to discuss options with you and see if we can help. We recently started discussing options with consultant/agency to figure out how to best work together. Please reach out to us at [email protected].
