These are some payment webpages I built for a desktop app. There is a free version of the desktop app. When the user wants access to the full version of the desktop app they can click a link in the app that will take them to the payment webpages. The payment pages allow the user to purchase a limited or full version of the desktop app and they can upgrade from limited to full. There is also a promo code CMS so that the owners of the app can create promo codes for limited, full and upgrade.

The payment pages were built with HTML, CSS, JavaScript, PHP, MySQL and the Braintree Drop-in UI. The project date is January 2016.
