A catalog is a complete set of plans, add-ons, credits, and components with its own configuration. An account used to have exactly one. Multi-catalog lets you run several side by side, so you can offer different packaging and pricing to different audiences without standing up separate accounts. Use it for region or currency-specific pricing, for separate brands or business units, or for a self-serve catalog running alongside a sales-led one.

A company can hold plans in more than one catalog at the same time, each with its own subscription and billing cycle. Existing accounts are unaffected. Single-catalog accounts and their current API calls keep working with no change, and multi-catalog accounts pass a catalog ID on entitlement checks to resolve the right plan.
