Microsoft AppSource (part of the Microsoft Commercial Marketplace) helps business users find and try software-as-a-service (SaaS) apps from Microsoft and its partners.
The Microsoft commercial marketplace is a catalog of solutions from our independent software vendor (ISV) partners. As an ISV member of the Microsoft Partner Network, you can create, publish, and manage your commercial marketplace offers in Partner Center. Your solutions are listed in our online stores, alongside our own Microsoft solutions, connecting you with businesses, organizations, and government agencies around the world.
The commercial marketplace is available in more than 100 countries and regions, and we manage tax payment in many of them. If you sell to established Microsoft customers, they have the added benefit of including commercial marketplace purchases in their existing Microsoft purchase agreements to receive a consolidated invoice from Microsoft.
