You can purchase bulk copies of supported iOS apps through Apple's Business Manager Program. This would allow you to purchase mass copies of an app without having to through the main App Store.
You will first need to sign up to the Business Manager Program - you can find more information about this here: https://www.apple.com/uk/business/it/. Once you have signed up, log in to the Business Manager dashboard and search for "Site Audit Pro". From there you can purchase however many copies you want all with a single payment.
During the checkout screen, you will be able to choose your distribution method for the app - the options are:
- "Managed": this will permit license allocation through your MDM service (if one is in use). This allows licenses to be re-allocated at a later date, if required. This method, generally, does not permit in-app purchases or subscriptions to be purchased.
- "Redemption Codes": this permanently assigns the app license to the Apple ID that the code is renewed through. It also allows users to purchase in-app purchases or subscriptions at a later date.
For any queries about the either the Apple Business Manager program or your MDM service (if one is in use), we recommend contacting Apple or the MDM service supplier directly as they will have the expertise to assist you thoroughly with their respective areas.
Note: This will only work for the iOS version of Site Audit Pro. There are currently no bulk purchase options for the Android version of Site Audit Pro.
