Trial Period For Vendors

Please, share your ideas - how to best showcase the individual stores for 30 days, so that the vendors could select a plan that better fits their goals and budget...

So far I have only two "manual" methods:

1. Create a free All-inclusive hidden plan and switch all new vendors to it for one month.

2. Create a trial Vendor usergroup with all permissions and choose it as default for the first automatically created vendor admin.
