Azure/Commercial-Marketplace-SaaS-Accelerator — reverse-engineered prompt

I want a production ready starter app that helps me launch and manage a SaaS offer in the Microsoft commercial marketplace.

Please build out the accelerator so it handles the normal marketplace subscription flow, including provisioning new customer subscriptions, tracking lifecycle changes, logging activity, and supporting marketplace based billing including metered usage and longer billing terms. I also want an admin portal where I can view and manage customer subscriptions and basic operational details.

Make it feel like a practical reference app I could deploy as is in Azure, but keep it easy to customize for my own SaaS product later. If there are setup scripts or deployment templates in the repo, use those so the install path stays simple and close to the intended experience. Please wire things up in a sensible, production minded way and include the key config I would need for local testing and cloud deployment.

If anything is unclear, check the project docs and current Microsoft marketplace docs online.
