The foremost thing that any buyer prefers is the cost efficiency. In most cases, the purchases of raw material constitutes up to the 50 percent of the total cost of the product while in some cases it can be seen up to 75 or 100 percent. Therefore, the main interest of the buyer is to lower his costs and by providing cost effective products, you can help the buyer achieve his ultimate goal.
Remember, going cost effective does not mean that you can compromise on the quality. A buyer will never consider a supplier who has variations in quality but will prefer the supplier who considers cost effectiveness and quality of equal importance.
Most of the buyers offer incentives to the suppliers who abide by the delivery schedule. As their business can get stuck due to the delayed deliveries, you should always deliver on time.
Helping the buyer to reduce his lead time is also an effective way of becoming a preferred supplier. This can be achieved by sharing information and increasing the use of technology.
