One Time Payment Products
If you want to sell access to content or products for download without requiring a subscription then you can use a One Time Payment product.
This is ideal for ‘tripwire’ offers, up-sells, down-sells, cross sells or any other situation where you simply wish to make an offer without a recurring payment.
NOTE: If you wish to create a One Time Payment product with a free trial then you will use the subscription settings with a trial but only one installment. View the full Subscription Settings tutorial here.
If you set the One Time Payment product to ‘0’ it will create a free product, however you will get more options with the actual Free product type.
