Helpful right from installation to delivery of my orders, a great tool indeed.
A Game changer. VERY cool tool. I used to track this manually across dozens of shipments on a Google Sheet. Now it’s just one click and get all the data {inbounds, cost, placement fees, overcharges}
Finally, a tool that shows me exactly where Amazon is slowing things down. I can see inbound speed differences by FC and stop guessing, it's really cool, never seen anything like this.
Before this tool, we had no visibility into why certain SKUs took 30+ days to check in while others were live in under a week. Now I can see exactly which fulfillment centers are dragging, how placement fees are affecting landed cost, and I can forecast inventory availability much more accurately.
It's very great tool for figuring out fees and finding BSRs quickly. I'd like a bulk scan feature and more detailed historical BSR charts, but the main features work well and are stable.
