Commerce Products, Quantity, and Checkout

Step 1: Open Native Products
Open Commerce, then Products. Native Catalog mode lets you create simple, service, digital, booking, variable, and subscription products without adding a separate store plugin.

Step 2: Describe the Product
Set the name, SKU, status, price, stock, description, image, tax behavior, fulfillment, and customer requirements. Use variants when options need their own price, stock, image, or SKU.

Step 3: Set Quantity Rules
Turn off customer quantity when a configured package must stay one unit per cart line. Customers can still add another separately. Use the order-limit option only when the whole order may contain one.

Step 4: Test the Full Order
Run a test from product display through cart, payment routing, confirmation, inventory, customer record, and order status. Verify both normal quantity products and fixed one-per-line products.
