Abstract: A dynamic quality control conditional purchase offer (CPO) management system is disclosed for processing CPOs received from one or more buyers for a product. The dynamic quality control CPO management system processes each received CPO to determine whether one or more sellers are willing to accept a given CPO. The dynamic quality control CPO management system initially evaluates received CPOs to identify CPOs which are not statistically likely to be accepted by sellers. If a received CPO is statistically likely to be accepted, the dynamic quality control CPO management system can submit the CPO for further consideration by sellers to determine if any seller actually accepts the CPO, or provisionally accept the CPO.
