How to charge a member for a Product.
*Note: this is also a useful feature to charge members for any miscellaneous charge, such as a one-time fee or prorating a membership plan.
Go to their member profile page
Hit the 'Create A Charge' button in the right rail
New invoice will open where you can click on the pink + to add items
Choose product from list and choose add to invoice
If you add the items and do not charge payment the invoice will remain "open". This is awesome because you can stack up multiple items over a series of days or weeks into a single charge. This will save you $$ as you will only have to pay the .30c per transaction fee one time.
