Abstract: The present invention extends to methods, systems, and computer program products for delivering customer specified receipt types at checkout. A customer specifies receipt delivery preferences at a mobile device (e.g., specifying delivery of a digital receipt and/or a paper receipt at checkout). The mobile device sends the customer's receipt delivery preferences to a receipt preferences database server for storage in a receipt preferences database. During a sales transaction, a point-of-sale (“POS”) system refers to the receipt preferences database (or a relevant portion thereof) to access the customer's receipt delivery preferences. Based on the customer's receipt delivery preferences, the point-of-sale (“POS”) system delivers appropriate types of receipts (e.g. digital and/or paper) to the customer.

Abstract: The present invention extends to methods, systems, and computer program products for auditing in-store sales transactions when a digital receipt is issued. A receipt application server formulates a digital receipt from digital receipt data received from a POS system. The digital receipt is sent from the receipt application server to an auditor mobile device at the location of the POS system. A human auditor can view the digital receipt during an in-store audit. In some embodiments, one or both of the receipt application server and the auditor mobile device reorder receipt entries so that items having specified characteristics are presented more prominently on a display. For example, receipt entries can be re-ordered such that higher profit margin items, bulkier items, or more likely to be stolen items are presented more prominently. As such, a human auditor is more likely to expressly audit these types of items.
