If you can arrange the opportunity to spend a week learning all of your internal processes by sitting down one week in accounting, one in customer service, one in production, one in shipping/logistics, one in IT, and so on...you will have the ability to not only understand what is happening when your customer places an order, but you will be able to respond to your customer's questions when they have them. You will also have contacts in all areas of the company for when you need to call on them, and most importantly you will sell more! You will sell more because your customers will see that you can influence things for them, making them feel more confident in your company because they have confidence in you.
