Bundles
One purchase that unlocks several of your tools, sold as a bundle on your own Stripe account.
A bundle is registered like a tool — New, kind Bundle, a name, the tools it holds — and sold like one. The kind Bundle is offered once the workspace has two tools. A bundle has its own checkout page, prices and customers. Holding the bundle is holding each tool in it. A licence, subscription or grant on the bundle entitles the buyer to every tool it names, in the popup and in the API.
A licence or subscription on the bundle unlocks each tool whole: every feature that any plan of the tool unlocks, whatever the bundle's plan is called. A feature that no plan of the tool unlocks stays refused, as it is to every buyer. See Access and features.
The extensions do not change. Each asks with its own tool id; Toolaby resolves the bundle.
A free trial of the bundle is a trial of each tool in it, and each inbox has one trial of a tool, however it comes: a buyer who has had the trial of one of the bundle's tools has no trial of the bundle, and a buyer who has had the bundle's has no trial of its tools, or of another bundle that holds one of them. The same goes for a subscription moved into the bundle from another Stripe account: the period paid there counts once for each tool the bundle holds (Move subscriptions).
On your Stripe account the bundle is a Product carrying the Entitlement Features of its tools; each tool is a Product with its own Feature. A bundle cannot hold another bundle or a tool from another workspace.
