A configurable product is an item a buyer defines by choosing from a set of options, variants, or parameters (for example size, material, finish, or add-on features) instead of buying a fixed catalog SKU. Each combination of choices resolves to a specific specification and, often, a specific price. In quoting, this means one product listing can generate many distinct quotes depending on how the buyer configures it.
How it works
The seller defines the axes a buyer can change: dimensions, materials, quantity tiers, engraving, mounting, tolerances, and so on. The buyer selects values along those axes, and the system (or the sales rep) maps the resulting configuration to a price and a set of production details. Some options are simple variant swaps, while others drive custom pricing that depends on labor, freight, or minimum order quantities.
Why it matters in B2B
B2B catalogs frequently sell things that do not fit neatly into Shopify’s fixed variant model. A product with three sizes, five materials, and optional add-ons can produce hundreds of valid combinations, which is impractical to pre-load as individual variants. Buyers also expect negotiated or volume-based pricing rather than a single sticker price. Configurable products handle both realities, which is why they show up so often in request-a-quote workflows.
Example
A merchant sells industrial shelving. A buyer picks 2 meters wide, powder-coated steel, 8 shelves, and reinforced brackets. That configuration is not a standing SKU, so the merchant captures the selections, prices the build, and turns it into a quote. Once the buyer accepts, the configuration flows into a Shopify draft order and checkout, keeping the custom spec and its agreed price intact through payment.
