This app and developer Thomas are both great! We started using this as soon as it was launched because we needed something for us to use with multiple vendors shipping items for us. The app almost worked perfectly out of the box and when we needed some little customisations needed to be added Thomas jumped in and assisted no questions asked. We had the app working exactly as we wanted within two days and we have been using it pretty much daily without issue for quite a while now. We have used it for just under 20,000 orders and it has worked exactly as expected.
