Cart configuration is mostly about the Cart Calculator sequence, the Promotion engine, and the abandoned-cart workflow. Get those right and the rest follows.
- Confirm Commerce Cloud is enabled
Setup, Commerce. Confirm the relevant edition (B2B Commerce or B2C Commerce) is enabled and storefronts are configured.
- Configure the Cart Calculator sequence
Set the order: Inventory, Promotion, Tax, Shipping. Each step writes to the Cart; the order matters because later steps see earlier results.
- Build Promotion records
Configure the promotions that should apply to Carts. Test promotion stacking carefully; conflicting promotions can produce unexpected discounts.
- Integrate tax and shipping services
Connect Vertex or Avalara for tax. Connect carrier APIs for shipping. The Cart Calculator delegates to these services during checkout.
- Configure abandoned-cart workflow
Define the abandonment window. Configure a Marketing Cloud journey to fire on Cart status = Abandoned. Track conversion to measure ROI.
- Cart Calculator step order matters. Tax before Promotion produces wrong totals.
- Inventory checks at Cart add instead of checkout cause frustrating Out of Stock messages mid-session.
- Promotion stacking can produce unintended discounts. Test combinations explicitly before launch.
- Abandoned-cart workflows convert better than almost any other marketing pattern; ignoring them is a measurable revenue loss.
