How to determine the spending of each app on Fly.io

Hi,

I am on the Pay-as-you-go plan, and I would like to know how much I am spending on each app monthly. I received an invoice, but it doesn’t include a breakdown of the costs. This information is important because I charge my clients for hosting. Is there a way to view detailed spending at the app level?

Thank you!

Anyone from fly team can help me with this?
