Working model
Purchase panel: decision table
Every viewer situation from the designs, and the panel each one gets.
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
A pack gives one customer a fixed number of downloads for one product. Re-downloading an asset bought on the pack is free.
Subscription lifecycle
A subscription gives one customer unlimited downloads of a product's included licenses for a period. Other licenses are still bought at their own price.
Product lifecycle
A product needs a main group, a license group and a base price. Its status is shown but no control changes it, and drafts are sold (D34).
