I'm not sure what your relationship with the manufacturer is but you would need to find out what their procedure for payment is. Most retailers buy a product and then sell it. You don't wait for them to sell a product before you are paid. They buy a certain amount, they sell it and if they dont they simply dont buy from you anymore. As far as your earnings. If you are an outside contractor, you would need to negotiate a rate with the buyer that allows a commision for you. Unless the manufacturer has worked one in, which i highly doubt they have.
There really isn't a way to help you with this. I find it a bit disconcerning that a manufacturer would aprove you as a wholesaler. They usually will not waste their time with those that do not have a proven track record.
good luck all the same.
Enjoy Life,
