Split WooCommerce orders by quantity, category, or stock status. Duplicate, merge, and return split orders from the admin.

== Description ==

Order Splitter for WooCommerce helps store managers split WooCommerce orders into smaller orders directly from the order edit screen. Use it when one customer order needs separate fulfillment, separate shipping batches, partial processing, vendor handling, or operational review.

The plugin works inside the WooCommerce admin area and supports manual order splitting by product quantity, category, and stock status. It also includes tools for duplicating orders, merging orders, returning split orders to the original order, and showing split-order labels in the order list.

== When to use Order Splitter ==

Use this plugin when your store needs to:

* Ship items from one order in separate packages.
* Process backordered and in-stock items separately.
* Split fulfillment by category, warehouse, supplier, or team workflow.
* Duplicate an existing order for admin processing.
* Merge orders that should be handled together.
* Undo a split by returning split orders to the original order.

== Split methods ==

= Split by quantity =

Move selected quantities from each line item into new orders. This is useful when a customer buys multiple units and only part of the order should be processed separately.

= Split by category =

Create split orders based on product categories. This helps stores route different product groups to different fulfillment teams or shipping workflows.

= Split by stock status =

Separate items by stock status so available, unavailable, or backordered products can be handled with clearer order batches.

== Settings ==

Go to WooCommerce > Settings > Orders to configure Order Splitter.

Available settings include:

* Allowed order statuses for splitting.
* Shipping fee handling for split orders.
* Split-order labels in the admin order list.
* Shop manager permission for splitting orders.

== Premium options ==

The free version focuses on manual order splitting and core admin order tools. The Premium version is available for stores that need advanced order automation and deeper workflow controls.
