Integrating Stripe Payment Gateway to a Knowledge Base Management System

vteam #557 has been working on a knowledge base management system. The client required stripe integration as a payment gateway to charge user subscription fee during the registration process. In this application, an option to purchase add-ons has been given to the users at the same time.

Problem

In stripe, once the subscription plans (fixed) are created, the membership fee cannot be altered. Due to the stripe restriction, it is impossible to charge both subscription and add-ons in one request.
