Abstract: Disclosed embodiments provide systems and methods for electronically determining a real-time registration. A method for electronically determining a real-time registration comprises receiving, from a user device, a request to register an item in a retail system and data associated with the item, determining a registration guarantee decision for the item, the registration decision specifying whether the item is or is not guaranteed, and registering the item in the retail system based on the determined registration guarantee decision. The method further comprises building a response for the determined registration guarantee decision and transmitting the response for the registration guarantee decision to a computing device associated with the retail system, wherein the registration guarantee decision comprises performing a comparison of attributes in the received data and attributes associated with items stored in the retail system to determine duplicate or similar items.
