Pay-What-You-Can allows your customer to determine the amount they pay for one of your products.
Select Products from your Simplero Dashboard
From the Products tab, select the product you want to offer the subscription price
Select the Prices tab
Add a secret price by clicking the white "Add a list price" button on the left-hand side under the List Prices or the blue + Add a price button in the upper right corner
Complete all relevant fields for the subscription price such as Name, Type of price, Amounts, etc.
Set price to whatever your minimum price is
In the Advanced Settings section, check the box for "Allow donations" option
Finish creating the price as normal and click the Save changes button
Enable price by clicking the Enable hyperlink at the far right corner of that price box
Now when someone selects that price option for the order form they can determine how much they will pay.
