Business Fundamentals and eCommerce
Commercial concepts
This domain tests whether you understand the business mechanics the platform serves. Know the difference between B2C and B2B flows: B2B introduces company accounts, requisition lists, quotes (negotiated pricing), shared catalogs, and purchase orders with approval workflows. Understand pricing layers: base price, special price, tier price (quantity-based), catalog price rules (automatic, applied to product listings and cart), and cart price rules (coupon-driven, applied at checkout). Confusing catalog versus cart price rules is a frequent trap - catalog rules have no coupon and apply broadly; cart rules can require a coupon and target the cart.
Merchandising and conversion
Be familiar with cross-sells, up-sells, and related products, and where each surfaces. Understand inventory concepts: stock sources, salable quantity, and multi-source inventory (MSI) allowing per-source allocation. Know tax configuration basics (tax classes, calculation basis) and shipping concepts (free shipping thresholds, table rates, carrier integrations).
Traps to watch for
Questions blur automatic discounts with coupon discounts, or assume MSI is the same as legacy single-source stock. Another trap: conflating catalog price with the final cart price after rules and taxes. Always ask "where does this rule apply - catalog or cart?" and "is this price automatic or coupon-gated?"
Worked example
A merchant wants 10% off all items in a category, visible on product pages, with no code. Rule of thumb: that is a catalog price rule (automatic, listing-visible). If instead the discount requires a code at checkout, it is a cart price rule with a coupon. Same percentage, different mechanism - the mechanism determines visibility and eligibility.
