In addition to what rlcarey stated, is it known whether or not a discount is given for customers that pay the distributor in cash? Many places offer a 5%, 10%, 15% etc for customers that pay in cash, ranging from the local gas station to a food wholesaler such as this. I'd say that in order to make your determination, more due diligence would be required. Does the customer have a website that you could browse to see if anything is stated? If not, consider giving the account manager a call to see if they know anything further about the business. If they don't, maybe it's time to call the customer directly.
