Legacy Leadership Collective requires complex knowledge to implement some of its features like complex payout calculations.

Also, it has a complex subscription where the user will get a 1st-month trial, the 2nd and 3rd months get a 50% discount and then the system will charge the full subscription price onwards.

I have also implemented a very popular payment gateway Stripe where I have utilized its APIs like customer, payment, subscription, product, price, and webhooks. Also, know how to test subscriptions with the help of Test Clocks where we can simulate billing scenarios through time.
