How to modify Joomla´s User Group after payment?

Hi, i´d like to know how can i modify an user group access after a hikashop product payment made by the user?
Is it possible that when someone buy a product, the only one function of that product is to automatically change the joomla user group of him? thanks for the attention

Hi,

That's not possible actually but that's something which will be in the next version of HikaShop (to be released next week).

Sounds good - subscription feature?
Will it be in the free or only commercial versions?

It's not really a subscription feature. It's more simple as there is no period of subscription and reminder near the subscription period's end, etc.

Since it's related to ACL handling, it will be in the Business version.
