Ann: Pushpay 2019 Annual Results Announcement, page-6

PPH will be paying Microsoft fees for their use of the Azure platform. In the past this was a significant expense. If the charges are based on a interaction basis where an interaction is an activity between a PPH customer and the platform, then these fees will continue to grow in keeping with the number of end users of the system, where an end user is a church member who uses the app to make a donation, as well as a church administrator who is accessing the platform. Probably there is a matrix of fees based on CPU usage, disk storage, network activity, etc.
