Jotform App: Is it possible to sell subscription for my app?

I also ask you if it is possible to create both access for clients to free resources but also access via subscription, monthly and/or yearly?
Waiting for you kind reply, I'm sending my best regards.

Hi Laura,

Unfortunately, We do not have a subscription option that allows you to charge your clients to access your app. While the feature you’re looking for selling subscription through app directly isn’t currently available, rest assured we’re always working to add new services and features to Jotform. 

I've gone ahead and escalated your request to our Developer Team. When or if it's developed depends on their workload, how viable it is, and how many other users request it. If there are any updates, we’ll circle back to this thread and let you know.
