How it works

Everything you need to merge Shopify orders

01
Auto-merge with smart rules
New orders from the same customer are merged automatically based on flexible rules - like time window or matching shipping address. Or get email alerts for merge suggestions and confirm them yourself.
02
One-click manual merging
Merge orders right from the Shopify orders page or inside the app - select the orders, click merge, done.
03
Reports stay accurate
Sales and tax data stays intact when orders are merged, so your reports and analytics keep working like before.
04
Merge history with undo
Every merge is recorded, and most merges are reversible - undo them right from the app if something changes.
