Unfortunately, Microsoft does not support models for Indirect Sellers that allow them to buy subscriptions for their own use, therefore Indirect Sellers are unable to sell/purchase subscriptions for Internal users via their own platform.
This business rule is regulated by Microsoft and cannot be changed by us, however; in certain circumstances, Microsoft may offer the opportunity for you to purchase subscriptions from them directly.
If purchasing directly from Microsoft is not an option, you will have to establish an End Customer relationship with Microsoft. This would allow selling subscriptions to Seller organization (as End Customer), not as a seller.
AppXite provides the opportunity for Sellers to purchase licenses as End Customers from solutions.apxite.com platform. Please contact the Customer Success Team (email@example.com) if you need assistance.
