Batch-processing of open tabs associated with one or more customers of a merchant is described. An identifier and/or payment instrument associated with the customer may be determined and a tab data structure associated with a customer may be created. The tab data structure may be configured to store interactions between the customer and the merchant. Details of transactions between the customer and the merchant may be stored while the tab remains open. In response to determining that an event has occurred, the open tab(s) may be closed and the stored transactions may be processed via a batch-processing technique. In this way, the open tabs associated with the customer and/or the merchant may be processed in batch, thereby reducing the level of interaction and resources required of the merchant and customer to process tabs individually and reducing the amount of delayed and/or lost funds.
