Let's say you want to match the availability of a product, say a truck with a customer who wants to hire said truck. The trucks are continually looking for the best paying business and the people who need the trucks are always looking for the cheapest truck. Obviously there are a lot of trucks and a lot of potential customers out there. My question is, is there a computer program available where you can enter in the availability of the trucks and it will match them up with the (pre-entered details) of the customers who need a truck? Strange question. Sorry.
