The ease of use for both buyers and sellers in terms of signing up and being able to find each other. It's helped us grow our business significantly over the last year as we've been using it more frequently and are now seeing much higher transaction volumes than before. I would like to see some improvements with regards to their UI/UX and also that they could handle larger transactions without too many issues. We have found them very easy to work with and will continue working with them. They do what they say they're going to be doing!
