We've been using sellerboard for about a year now and we're really using it and it's in our day-to-day use, because sellerboard helps us keep track of our key metrics, of our key KPIs. And we also see all the hidden costs there. Thus guys, I can only recommend it to you. Try it out. Sellerboard is free in the first month. Just check it out, if it can help you. I believe every successful seller needs a tool that lets you have a close look at your metrics, where you see all your costs, because that's the biggest hurdle for most sellers. They do not know how much their remissions are, how much fees they pay exactly. That's why people, keep an eye on this, have a go with it and keep your eyes open.
