Is a part of your working day about getting your goods out of the door; to your customer on time; and in the condition that they left you in?
Is your desire to work with delivery providers you can totally depend on to enhance your reputation? Do you need suppliers with the capabilities to ensure customer orders are being fulfilled no matter what they are and when they are required, even if that is on the same day?
Is cost control and up to date information important to you? Do you enjoy working with delivery partners who have a professional but friendly approach? Finally, is your desire to work with people who make your job easier?
