Nowadays, the number of sell in and sell out are not balance that the number of sell in is more than the number of sell out and then, It will be non-moving products within 90 days of Home pro and 120 days of Thai watsadu after sell in. If there are not sell out, It will return to company that there are cost. For suggestions, we have to develop and try to make the number of sell in and sell out are balance. I think factors that increase the number of sell out are 1.) PCs: have to be the product professional and we have to encourage them to make sell out, 2.) Promotion: I think we have to have sales promotion for support PCs to sell easier and 3.)Products : have to produce the new products that superior innovation.
