We use this app, however, be very careful with settings. As far as I can see, the defaults could cost you. Last year we merged several thousand $ worth of orders but it seems the the app created new orders as if it they were additional sales. Shopify then overestimated the 1099 to the IRS—showing elevated sales. As a sole proprietor or LLC, you'd need to enter the excess as "returns and allowances" or similar in schedule C of your 1040 federal return. Simply stating your actual sales would underreport sales sent to the IRS and could cost you an audit, and a lot of additional red tape. Depending on your State, the problem could even be further exacerbated.

We set up the app and had their team double check it before launch. We launched it and bam we lost $1,500+ due to orders being double printed inconsistently - it was hard to catch for us. Upon reaching out about the massive issue, they ignored me now three times. I wish I could upload the emails and the chats! Unprofessional company, buyer beware. We're contacting shopify and working with a lawyer to recover the sum.

This app is extremely useful. We've had instances where someone places a follow-up order shortly after their initial order. Due to the shipping dimensions of our product, that follow up order can double international customers' overall shipping costs. Potentially, that's an extra $60-80 or more, depending upon the destination. Order Merger makes it super-simple to combine orders, so we can refund the extra shipping cost. Such a deal... being able to merge 5 orders or less, per month, free of charge. I'm told the app doesn't affect website speed since it works on the 'back office, and not on the storefront. Support is really fast and effective, too. Depending upon your sales volume, you might want to choose to merge manually... at least while you're checking it out.

Love this app. And the customer service. Very quick and friendly staff. They were very fast in replying and fixing an issue. Cheers to the team!

I used this app to help me merge my orders and ran into a little issue. Their customer service team was A1! They were able to see the problem I had, provided clear solutions and walked me through the entire process with ease. Great communication, fast replies and 24hr service. T

Great app, a must-have when you're using a post-purchase upsell to combine orders into one. The support is quick and helps solve any issues.

This app is essential to our business model which offers local delivery twice per week, with two cutoffs for customers on different days of the week. Our routing software can only send one order to one stop, and multiple customers like to add on to their order before the deadline. We needed a way to combine those orders and send them as one -- this is the ONLY app I have found on the app store that does this. We had some real trouble implementing the app in the beginning, and it caused a huge headache with orders merging that should not, and the other way around. I was able to work with support to get these issues resolved, and they told me that this app now has a full time developer. They are asking me for improvement suggestions, which is great. Overall, this app works well now that the bugs were addressed, and I am hopeful they just keep improving. Highly recommended if you need to merge orders.
