On VTEX, customers may receive their orders split into several packages, regardless of whether the order has been split on the platform. Customers can receive their order items in separate packages in the following cases:

• Order with different sellers: An order is generated for each seller, resulting in at least one package per seller's delivery.
• Selection of white label sellers: Orders involving white label sellers may be delivered in separate packages.
• Seller with different SLAs for shipping items: Even if a single seller fulfills the order, different product SLAs can cause the order to be split into multiple packages.
• Pre-sale products: Orders containing both pre-sale and regular products will be delivered in separate packages.

When an order is generated, the estimated delivery date at checkout applies to both pre-sale and regular products. However, this is only a delivery estimate. Once payment is approved, the order is divided into different packages, one for pre-sale products and one for regular products.

The delivery date for each package will be adjusted based on the shippingEstimateDate for each product, which can be checked via the Get order endpoint.

To avoid splitting packages in orders that include pre-sale products, you can configure shipping groups. This allows you to group all packages to be delivered by the same carrier and from the same loading dock into a single shipment.

By configuring shipping groups, this behavior will be applied to all orders with different delivery dates, not just those containing pre-sale products.

To configure shipping groups in your store, follow the steps below:

1. In the VTEX Admin, go to Store Settings > Shipping > Settings, or type Shipping in the search bar at the top of the page and select Store Settings / Shipping.
2. On the General Settings page, in the section Delivery Groups, enter the desired number of days for the shipment in the field Create shipping groups with intervals of {X} day(s).
3. Click Save.
