One of your customers is not keeping up with his payment obligations. Not in relation to you, but in the context of other business relationships. This could be an indication that your supposedly solvent customer is in financial difficulties. Wouldn’t you want to know about that as soon as possible?
Your goal is to have sound and timely information about the payment behaviour of your new and existing customers. The creditworthiness of your business partners is something you need to know about to make the right decisions. That’s how you manage the risk.
