Cleverific Order Editing

We wouldn't use Shopify if not for this app. As you know, Shopify doesn't allow you to change completed orders due to liability concerns, but Edit Order is the next best thing. Though it's more of a work around than anything else, it works seamlessly enough to where your customers wouldn't know the difference if your order was changed after the fact.

Give yourself a little bit of time to get a feel of the mechanics of the app, and be sure to test the app out a lot on dummy accounts before going live with it. I recommend taking their tutorials and walkthroughs just so you have a better idea of what to expect from the app.
