Don't even both with this service. It has so many problems, it's insane. Honestly, Selro seems like it's alpha/beta software and not a fully working version that they should even be charging for yet. We've been using Selro for 2 months and have lost almost 20,000 dollars in sales because there are so many errors.
The biggest problem (amongst dozens) is that the software tells you that your items are listed on your marketplaces, even when they've failed (and they fail A LOT). This makes the software practically unusable by itself, as you have NO IDEA what is listed and what isn't.
The tech support is almost non-existant too, as they say they will address the issues, and then you never hear back on it. Do yourself a favor and just pay a little more for a working service. Selro is absolutely horrible.
