It is important to keep track of your vendor’s performance. If you realize that they are continuously shipping orders late, sending incomplete or incorrect orders, or sending low-quality products, communicate your concerns to the vendor. If it is something you do not think is improving, you may need to end your contract with your vendor.
One way to learn about a vendor's reputation is to talk to their past and current customers. You want to find a vendor that is reputable and trustworthy. Look for product testimonials on the vendor’s website. A testimonial is a statement from a previous or current customer that describes how they feel about a product or service. This will allow you to learn about the vendor’s customer-client relationship, as well as their products.
