How commerce works

A retailer orders two hundred shirts for a store opening. The buyer agrees on the sizes, price, and delivery date. Some shirts are in the warehouse, and the rest are due from a supplier. Before confirming the order, the sales team needs to know whether both groups can reach the retailer in time.

That question brings together several parts of commerce. The catalog identifies the shirts. Inventory describes what is available. Purchasing explains what is expected. Fulfillment gets the goods to the retailer. Each part supplies information the others need to make a useful decision.

Start with the goods

The retailer wants a hundred medium shirts and a hundred large shirts. Two hundred shirts in other sizes will not satisfy the order. Each size needs its own SKU, an identifier that lets everyone refer to the same item when buying, counting, and selling it.

The warehouse may organize stock by shelf, the buyer by collection, and the retailer by store. Those different views can still refer to the same products. A shared identity lets the sales team compare the requested sizes with the stock on hand and the supplier’s expected delivery.

Connect the agreements to the work

A sales order records the retailer’s purchase, including the products, quantities, price, and destination. A purchase order records the business’s agreement to buy goods from its supplier.

The orders explain what each party has agreed to do. As the work proceeds, other records explain what happens. A purchase shipment identifies goods coming from the supplier. Receiving confirms what arrived. A fulfillment order gives a warehouse the instructions for its part of the customer’s purchase. A shipment records what the warehouse sent.

These records refer back to the agreements. If the supplier delivers only eighty of the hundred medium shirts expected, the buyer can see the shortage without changing the record of what was ordered. The sales team can then work out how that shortage affects the retailer’s delivery.

Ask the person who can confirm the fact

The supplier can confirm dispatch. The receiving team can confirm the contents of the delivery. The warehouse can confirm that the retailer’s cartons have left.

Making those confirmations available saves everyone from repeating the investigation. Customer service should be able to find the shipment without asking the warehouse to reconstruct yesterday’s work. A buyer should be able to see a short receipt before placing another purchase for the same stock.

Use the information to make a promise

For the store opening, an incoming quantity alone is not enough. The sales team needs its expected arrival, the time required to receive and pack it, and the delivery time to the retailer. Stock already reserved for other customers also needs to be accounted for.

With those facts, the team can confirm the full order, arrange an earlier supplier delivery, or agree on a smaller first shipment. The following chapters explain the records and working practices that make those decisions possible, from describing a product to deciding when to buy it again.
