Can we please give the option for members to purchase a monthly or annual pricing plan!
Hi @Steve_Whelan,
First off, a warm welcome to the Wix Studio community! I see that this is your first post - looking forward to seeing more interactions 
Right now you can create separate plans for yearly or monthly subscriptions. I know that the Pricing Plans product team have this request in their headlights.
You can vote for it here: Pricing Plans Request: Allowing Clients to Choose Their Payment Frequency | Help Center | Wix.com
As soon as the team start working on this, you will see it in the new Wix Public Roadmap.
