A supplier representative for the goods marked above with a red arrow is coming to see you soon; well, how much of their stuff do you actually move now? The problem here is that these products may come through several of your suppliers
Well, it's simple to find out; we use the manufacturer.
Go to reports; look here
Look at the Manufacturer Stock Sale report pointed out by the red arrow, call up a supplier for the exercise, put in the last 12 months and follow my example below.
Now click the item marked with the red arrow.
Now select a supplier. I picked WAY, but you can select anyone more relevant to you, and you will see what you have sold for them in the last 12 months.
