What Comengine Does
About the machinery of e-commerce — catalog, cart, checkout, and orders explained as one engine developers can build on.
Modeling products, variants, and pricing so the store scales.
How carts hold state, apply discounts, and survive abandonment.
Payment, tax, and shipping steps that do not lose the sale.
From placed order to fulfillment, returns included.
Clean interfaces between storefront, engine, and back office.
Build versus buy, and how the major engines differ underneath.
How Comengine Works
Learn what catalog, cart, checkout, and order systems each do and how they connect.

Use the API patterns to extend the engine without fighting it.
