Design An Ecommerce Payment System | System Design

Let’s talk about payment systems in the context of a marketplace product, such as an ecommerce system where you have both a buying party and a selling party.

We also talk about some technical details such as a double-entry ledger system and how to reconcile or fix financial inconsistencies.
