Set-up #1 - Create a $0 membership
In this scenario, setting up a $0 membership will bill and create an invoice for them every billing cycle (a month, 4 weeks, 2 weeks, etc). This will allow deferred store payments to bill on the billing cycle.
Step 1 - Select your unlimited subscription (or your version of similar membership).
Step 2 - Create a "Coaches" or "Employees" payment plan by selecting blue button "Add Payment Plan" at the top of the screen
Step 3 - Set-up the membership for $0 and billing cycle of your choosing
Step 4 - Assign membership to coaches
Set-up #2 - Assign your Unlimited Plan (or your version of similar membership) for Free
In this scenario, assigning a normal membership for free will NOT generate an invoice and deferred payments will be left open as "pending". This is an easy way to set-up a membership if all you want to do is grant access someone (coaches/employees) to programming and classes for free WITHOUT any payment method on file.
