Systems and methods to implement point of sale (POS) terminals, process orders and manage order fulfillment

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions for:

• receiving, at a server, data representing a first transaction from a first device, the first device associated with a first customer;
• generating, at the server, a unique code representative of a coupon, wherein the unique code is configured to be transmitted and displayed in digital form, and the unique code is configured to be scanned by a point of sale apparatus, the unique code associated with a user identifier associated with the first customer;
• synchronizing, by the server, a coupon status data structure to the point of sale apparatus while a network connection between the server and the point of sale apparatus is available;
• detecting, by the server, that the network connection to the point of sale apparatus is unavailable;
• detecting, by the server, that the point of sale apparatus has returned to online mode after the network connection is restored;
• receiving, at the server, a redemption request from the point of sale apparatus, the redemption request associated with a second customer associated with a second device, wherein the second customer is different than the first customer, and wherein the redemption request includes the unique code and wherein the redemption request is associated with a redemption that occurred during offline mode when the network connection to the point of sale apparatus was unavailable;
• validating, by the server, the unique code for redemption;
• updating, by the server, the coupon status data structure based on the validation;
• and
• synchronizing, by the server, the updated coupon status data structure to the point of sale apparatus maintaining data consistency between the server and the point of sale apparatus.

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to at least:

• receive, at a server, data representing a first transaction from a first device, the first device associated with a first customer;
• generate, at the server, a unique code representative of a coupon, wherein the unique code is configured to be transmitted and displayed in digital form, and the unique code is configured to be scanned by a point of sale apparatus, the unique code associated with a user identifier associated with the first customer;
• synchronize, by the server, a coupon status data structure to the point of sale apparatus while a network connection between the server and the point of sale apparatus is available;
• detect, by the server, that the network connection to the point of sale apparatus is unavailable;
• detect, by the server, that the point of sale apparatus has returned to online mode after the network connection is restored;
• receive, at the server, a redemption request from the point of sale apparatus, the redemption request associated with a second customer associated with a second device, wherein the second customer is different than the first customer, and wherein the redemption request includes the unique code;
• validate, by the server, the unique code for redemption;
• and
• update, by the server, the coupon status data structure based on the validation;
• synchronize, by the server, the updated coupon status data structure to the point of sale apparatus maintaining data consistency between the server and the point of sale apparatus.
