Ecommerce Task

Plan the shipping promise for mixed carts

Test how stocked and preorder items split, then choose a promise the checkout and fulfilment team can support.

“This is costing me confidence in the delivery promise and risks confusing buyers after they place a mixed order.”

The result you need

Customers see an accurate delivery choice and the team has a tested route for every shipment group.

What is happening now

Where the work gets stuck

One cart contains in-stock products and products with a later ship date.

When it starts
A test checkout splits the cart, changes the delivery charge, or omits the wait-or-ship choice the merchant expected.
What makes it difficult
Locations, profiles, inventory, purchase options, checkout upgrades, costs, and fulfilment capacity shape the available routes.
What progress looks like
Representative mixed carts show the approved shipment groups, prices, dates, wording, order records, and fulfilment actions.

What to try next

Test and publish a mixed-cart shipping plan

Choose a supported shipment plan from real checkout evidence and give fulfilment a route for every group.

Open the practice

Before you act

Check these limits

  • Test the current checkout instead of assuming a combine choice exists.
  • Record who pays each shipment charge.
  • Align the promise with available stock and operational capacity.
