It's going in that direction (https://uservoice.paessler.com/forums/966009-administration/suggestions/50790047-self-service-portal-for-prtg-enterprise-monitor-of) but for MSPs.

As an MSP, we provide our customers with PRTG sensor licenses, and some of our customers run their own dedicated PRTG installation. To ensure correct per customer billing and to technically prevent overuse, we need a sub license for each customer instance with a fixed sensor limit and bound to the System ID. Today, we have to contact support every single time and provide the System ID and the required sensor count so a sub license can be created or adjusted. This is unnecessarily slow and cumbersome in daily operations and does not scale well when managing many customers.

Please enable MSP partners to create and manage sub licenses independently, ideally directly in the Paessler Portal, or alternatively directly in PRTG as part of license management. The key requirements are the ability to create sub licenses without a support ticket, adjust sensor limits, revoke sub licenses, and have a clear overview list including customer assignment and System ID. This allows customers to work in their environment with read and write permissions without requiring constant manual checks or making onboarding and changes dependent on support. This would be a major value add for all MSPs and for Paessler, reducing support workload while improving scalability and partner experience.
