You can define in your packages at which position all photos, only group photos or only single photos can be selected.
This way, you can prevent your customers from ordering a group photo in the package as a download, for example. Or say that only a single photo may be selected at the position of the stickers.
You can print out a list of access card passwords, children's names, and space for a comment from each class or group individually.
This way, you always keep an overview, even with large jobs.
