OrderSplit Pro ‑ Split Order

The app works consistently, and can target almost anything we want - Tags, SKU, Metafield... Also supports exclusions and has an audit log for split orders. It works super consistently even as we get thousands of orders a week, works perfectly with Shipstation and the best part is the developer who responds quickly and efficiently, triages and fixes errors and is willing to help with custom logic if and when we need it. This is one of the best apps we've found for Shopify!
