Make sure you are not running into the inventory software issue that will cause you to not re-order product even if its selling well on Amazon.
I use Restock Pro and the software has what I would consider a bug that keeps inventory as being on order even after you receive in the product.
When I order from wholesale suppliers I create a purchase order in restockpro. When I receive the inventory I update the PO with the product I have received and if their are back order product the PO does not get closed but remains open until the back order product is received in.
In Restock Pro when you leave a PO open even if you entered the inventory you received and saved the PO with the updated receive products it still shows in the inventory that all of the items in that PO are still on order.
One of my largest suppliers frequently has backordered products that they send me as they receive them so I have many PO’s open from them.
What I found is that this caused many products to not show up in the suggested re-order screen because RestockPro still saw those items as being on-order even though I had long since shipped the product in to Amazon and sold out of that product on Amazon.
I literally have tens of thousands of dollars in inventory out of stock on Amazon because the system still thought I had them on order when I had already received them in.
I hope my issue will be a lesson for you and prevent something like this form happening in your business and costing you thousands of dollars.
