Variable Price is an add-on for the WP Stripe Checkout plugin that can be used to add a price field to your Stripe payment buttons. This lets buyers set the amount they will pay for your products. It can also be used for accepting Stripe donation payments.

How to Enable Variable Pricing
Open the product in question (Stripe Checkout > Products > Edit) and Enable Variable Pricing in it.
When the button for this product is rendered on the front end, a price input field will appear that will let buyers set the amount they want to pay.

The default label for the price field (Amount) can be customized in the add-on settings (Stripe Checkout > Variable Price).
