Ecommerce software examples — the stack, layer by layer

The key facts

• The stack has five layers: storefront, payments, shipping/fulfilment, marketing, and the operations record (stock truth, orders, invoicing).
• The storefront platforms (Shopify, WooCommerce, and others) are the layer most people mean — but they are not the whole stack.
• The operations layer is where wholesaler needs diverge from retail: per-customer pricing, repeat orders, purchase orders from demand.
• BSimple's boundary, plainly: no storefront — Shopify orders import by webhook into the operational flow; invoicing stays between the store and your accounting system.
• The full picture: how the inventory record works is the hub page for everything above.

The five layers, with examples

Storefront. Where customers buy: Shopify and WooCommerce are the names most searches mean, and they are genuinely good at their job — product pages, carts, checkout. Calling these "ecommerce software" whole is like calling a shopfront a warehouse.

Payments. Gateways and merchant facilities — often bundled with the storefront, occasionally worth separating for fees and reconciliation control.

Shipping and fulfilment. Rates, labels, tracking notifications. Stores handle the notification half well; the warehouse half — pick, pack, dispatch against live stock — is where stores borrow from the layer below.

Marketing. Email, ads, retention tools. Real software, different page.

Operations record. The layer under the store: what is actually in stock, what has been promised, what must be purchased, and how an order becomes an invoice. This is BSimple's layer, and for wholesale it is the one the storefront cannot fake — the ecommerce inventory comparison covers what changes under real volume.

Where the layers meet: the store and the stock record

Every store that sells physical goods has an implicit promise at checkout: the item is real, and the quantity shown is true. When the storefront and the operations record are disconnected, that promise runs on manual re-keying — orders copied into a spreadsheet, quantities adjusted by memory — and overselling is a when, not an if. The integration question is therefore structural, not optional: how do orders reach the record, and how does truth reach the store?

In BSimple's case, Shopify orders arrive by webhook into the same flow every other order takes — delivery slips, picking and packing, stock deduction — while invoicing stays between the store and your accounting system (the automation overview shows the path). There is deliberately no BSimple storefront: the store is Shopify's job; the truth under it is ours. The Shopify-specific comparison and the stock-side question cover the connection in depth.

Choosing by layer, not by brand

The useful evaluation is per layer: pick the storefront that fits your channels, take payments where the fees and reconciliation work, and then be deliberate about the operations layer — because that choice outlives storefront redesigns. Wholesalers should weight it hardest: per-customer pricing, repeat order patterns and purchase orders from demand are operations-layer jobs that no storefront does natively. The ecommerce order-management angle and the trial close the loop — one afternoon with your real products tells you whether the record under the store holds.
