Bundles and kits

A bundle is several products sold as one line: a starter kit, a gift set, a machine with its consumables. The customer buys one thing; your warehouse picks four.

How it works

• A bundle is composed of existing products rather than being a new product with its own stock. There is nothing separate to count.
• Selling one decrements every component, so a component that sells out on its own also limits the bundle.
• The bundle carries its own price, which is the point — a bundle priced at the sum of its parts is a list, not an offer.

Why the shared stock matters

The common way to build bundles is as a separate product with its own quantity, kept in step by hand or by a nightly job. That works until the components sell individually, at which point the bundle is advertising stock that has already gone.

Because a bundle here is a composition rather than a copy, the arithmetic cannot drift.

What it does not do

It will not assemble anything. If a bundle is physically made up in advance and stored as a unit, that is a build rather than a bundle — see configure to order.
