Ecommerce Stack

An ecommerce stack is a software architecture designed to manage online buying, selling, payments, inventory, customer accounts, orders, and fulfillment through an integrated digital commerce platform. These architectures power online retail stores, subscription businesses, direct-to-consumer brands, business-to-business commerce, digital product platforms, and hybrid commerce systems.

The primary goal is to provide reliable purchasing experiences while coordinating products, inventory, payments, fulfillment, customer management, and operational workflows efficiently at scale.
