Add-ons in Stigg represent separately billable functionality that extends plans.

By default, add-on entitlements increase the plan limit, for example: if a plan includes access to 10 seats, purchasing an add-on for 20 seats would result in a seat limit of 10 + 20 = 30 seats; however, there are cases where vendors would like the add-on entitlement to override the plan limit.

We've now added the ability to control this configuration using no-code. The configuration can be defined separately for each of the add-on's entitlements.

When adding an entitlement to an add-on or updating an existing one you can specify the entitlement behavior - whether to increment the plan limit or override it.
