Rules
Purchase panel: decision table
Every viewer situation from the designs, and the panel each one gets.
Product lifecycle
A draft is never sold. Publishing needs names, content no other published product sells, prices and a checked customer view.
Agreement term
A discount, subscription or image pack applies while it runs: between its dates and turned on. Own terms beat group terms.
Purchase panel on the asset page
Which panel a viewer gets depends on their plans. A subscription wins over a pack. Without a covering plan, the viewer buys a one-off license or asks sales.
Cart and checkout
The buyer type follows the workspace. Paying requires accepting the license terms (and the supplier instructions, when an image has any); private persons must also waive the right of withdrawal in a separate checkbox. Removing the last image returns to the empty cart.
Pack lifecycle
An image pack gives a customer a fixed number of downloads of what it covers. Downloading an image again is free.
Subscription lifecycle
A subscription gives a customer (or every member of a group) unlimited downloads of what it covers for a period. Other licenses are still bought at the customer's price.
