This App, Order Editing, has been a lifesaver for us. I also need to mention that the CEO was personally involved in supporting us and was available multiple times with great follow-up to get us to the point we needed to be at. We were able to complete almost a thousand pre-orders with their help. Highly recommended. We also tried two other apps, and the tech was bad, features were removed without warning, and the support was poor. Kudos to Order Editing for a great product and a great user experience.
