Domain, hosting and billing operations

The owner reports a SharePoint-based domain and hosting management system, including customers, hosting packages, domain registration records, renewals, invoices and a due-invoice dashboard.

This ASP.NET Core corporate site presents services and captures enquiries. It does not query live customer records or create billing transactions in SharePoint.

A separate authenticated API or server-to-server connector can later surface approved customer actions. Avoid public exposure of personal details, prices or invoices without per-user authorization.
