Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/vanbess/plugin-woocommerce-order-merger/archive/refs/heads/master.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
PLUGIN: Order Merger for WooCommerce
Merge 2 orders into 1. Handy for cases where the same customer places another order within a few hours of the first.
NOTE: this is a bespoke plugin created for a client, so will likely need modding to work for your use case.
