You could try Apple Business Manager - Business - IT - Apple

Even government and non-profit entities get a D-U-N-S number. My wife received one when she started her business and filed for a DBA (doing business as).

For smaller orgs, Apple Business Essentials is one of the best options out there. You may also want to check into Jamf Now or Mosyle.

For larger orgs, you may want to look into more powerful options such as Kandji, Jamf Pro, and Mosyle (This one straddles both the small and large orgs for the same price).

No matter what you use, you want to set up Apple Business Manager and a real MDM platform. This will allow you to remove activation locks and control how the devices are used. I have devices that range from being locked to a single network and app to devices that are essentially only managed so we can lock the devices if lost or stolen, or so we can remove activation lock if enabled.
