For iOS and Mac apps, a download is marked a business download when the app is downloaded by a qualifying company through Apple's Volume purchase for business program.

All apps are eligible to be sold through the Volume purchase for business program unless the developer opts out of the program through App Store Connect.

Business downloads are usually downloaded in bulk, and may result in spikes in your download trend for the day. For paid apps, business downloads are usually purchased at a discount so revenue will be lower than you'd expect.
