A system is presented that facilitates transactions for products to be completed and product inventory tracking to be performed in real-time even if the products are brought to the location of a customer prior to the transaction. The system completes transactions by accepting and settling cash, credit card, debit card and other forms of payment in real-time. In general, the system includes three basic components: an application module, a back office portal and a portable device. These components may be placed in communication with each other in various configurations to perform various functions that enable product tracking and transaction completion.
