Payment system

Description

Payment system integrated with Openpay (https://www.openpay.mx/) to handle purchases for different products. Each product can have different plans and each plan can have multiple addons.

Every product can be configured according to different requirements, in this case, following products were created:

• Product A: a subscription product, as when the customer purchases this product, the features are enabled and the customer can use them without any limitation until plan has expired. For example, this could be a product similar to Spotify/Netflix, when you purchase a certain plan, you are able to use all the features until the plan is expired. Anyway, you can upgrade at anytime.
• Product B: a refill product, as every time a purchase is performed, the customer buy the same bag of utilities. This can be integrated with external systems to refill the capabilities for the customer. For example, if Product B is based on hours, the customer can buy 100 hours of your services every time.
