Modern commerce isn't just a storefront—it's an ecosystem connecting product data, pricing engines, inventory systems, checkout flows, payment processing, and order management. Retailers need platforms that handle thousands of SKUs with variants, complex pricing rules (contract pricing, tiered pricing, promotions), checkout experiences for both B2B and D2C, and order orchestration across multiple fulfillment centers.

Most Salesforce partners treat commerce as "CRM with a shopping cart." This leads to fragile architectures that break when you add variant logic, implement dynamic pricing, or integrate marketplace channels. Commerce requires retail-specific thinking from day one.
