In the past many contractors have had customers that simply refuse to pay. These contractors have had limited resources for retaliation, and employing collection agencies or mechanical liens, however effective, can be costly. Even when the contractor is in the right it can still be difficult to recover what’s due. In the past the businessman had no centralized location for any client information regarding past delinquencies. Our goal is to inform the contractors of the delinquent customers before they start work; and by doing so the contractor has the customers’ payment history and can therefore avoid entering into business situations that might result in payment complications down the road.
