Checkout

How to how the cart behaves

Checkout maintains a cart of sellable items and continuously validates it against the latest product catalog. If a product, membership, or other sellable item becomes unavailable, checkout can remove it from the cart so staff do not finish a payment against invalid inventory. Quantity also respects stock limits unless the item is configured with unlimited stock.

How the cart behaves

Checkout maintains a cart of sellable items and continuously validates it against the latest product catalog. If a product, membership, or other sellable item becomes unavailable, checkout can remove it from the cart so staff do not finish a payment against invalid inventory. Quantity also respects stock limits unless the item is configured with unlimited stock.

  • Cart quantities are clamped to the current stock limit when stock is finite.
  • Variant-level stock is respected when a product uses stock and rates options.
  • Unavailable cart items can be removed automatically when the backing catalog no longer supports them.

Tips

  • Test checkout with real product, voucher, and discount combinations whenever inventory or pricing rules change.
  • Keep tax and fee settings aligned with the actual sales channel so totals match what staff and customers expect.
  • If stock-controlled products are sold in checkout, verify stock and rates behavior before launch so quantity clamping works the way the team expects.
