You'd have to provide more details about what you need to license: desktops, servers, virtual, SQL Server, etc.. Generally the freeware edition is good for some home users with small backup needs. It's not suitable for businesses and for those that need more advanced functionality like support for Windows Server, image backups, compression, encryption, and improved backup performance.

Depending on your environment size, we have two options:
1. Purchase our CloudBerry Backup perpetual licenses and purchase (optional) annual maintenance if you need upgrades / support. Check the Compare Pricing section to understand the editions for Windows and pricing: https://www.msp360.com/backup/windows.aspx
2. If you have 5 or more endpoints and servers and want centralized management for the environment, you can look into our Managed Backup product. It's a subscription. For small businesses, licenses start at $10 / month for Windows desktops before discounts. https://www.msp360.com/managed-backup

Let me know more and maybe I can provide a more detailed response.
