Hello,
The full name of HikaSubscription is "HikaSerial Subscription".
We realized that the core of HikaSerial can also support subscription systems via its content generation.
While HikaSubscription do provide classical features regarding action when a subscription start or expire ; it performs its action in a flexible way since it uses plugins for that.
You can have a subscription without actions ; so it will create a new HikaShop order each time the subscription is (automatically) renew.
Afterwards, if you need some special action (that I can't see in your email), it is possible to extends the component (like HikaShop) thanks to plugins and custom development.
