A computer implemented method, data processing system, and computer program product for managing transactions on point-of-sale terminals comprising a peer-to-peer network in a retail data processing system. A purchase transaction for a customer is initiated on a point-of-sale terminal in the system. Responsive to receiving a first input from a user of the point-of-sale terminal, the purchase transaction is suspended to form a suspended purchase transaction. Information about the customer is added to the suspended purchase transaction. The suspended purchase transaction is stored as a file on the point-of-sale terminal. Responsive to receiving a second input from the user of the point-of-sale terminal, a locally-stored list of suspended purchase transactions on the point-of-sale terminal is searched using the information about the customer. Responsive to locating the suspended transaction matching the information about the customer, the suspended transaction is selected to restart the suspended purchase transaction on the point-of-sale terminal.
