A great sales tool for wholesalers is to watch your clients’ stock. That way you can instantly find what products are missing from his/her warehouse and get an order on those barcodes. That way you can also reverse your clients’ refusal to give you an order sometimes. That tool gets even better when you have a record of his/her sales (to end users). This helps you predict his/her near future needs in products and get an easy order.
