Network site cart user interface having multiple user-specified currency formats

A system comprising:

• one or more hardware processors;
• and
• a memory storing instructions that configure the one or more hardware processors to perform operations comprising:
• detecting, via an application programming interface (API) server coupled to an application server implemented by at least one hardware processor via a client device, an edit to a shopping cart user interface, the edit indicating a request to change a parameter associated with a transaction, the application server comprising a heterogeneous pricing and payment system that comprises a price engine component, an order adjustor component, and an order presenter component communicatively coupled via at least a shared memory;
• based on detecting the edit, delaying, via the price engine component included in the application server implemented by the at least one hardware processor, processing of the edit until initiation of a checkout process associated with the transaction is detected, the parameter corresponding to a currency type, the delaying of the processing reducing network resource consumption by consolidating changes to the parameter affecting a result value of transaction into a unified transaction step for display;
• in response to detecting the initiation of the checkout process associated with the transaction, processing, via the price engine component and the order adjustor component included in the application server implemented by the at least one hardware processor, the edit including generating the result value based on a changed parameter associated with the transaction, the order adjustor component aggregating changes to the parameter calculated on a computer logic level by the price engine component and determining the result value of the transaction based on the aggregated changes to the parameter;
• and
• causing, by the order presenter component included in the application server implemented by the at least one hardware processor, display of the result value in a checkout user interface on a display component of the client device.

A non-transitory computer-readable storage medium comprising instructions that when executed configure hardware processing circuitry to perform operations comprising:

• detecting, via an application programming interface (API) server coupled to an application server implemented by at least one hardware processor via a client device, an edit to a shopping cart user interface, the edit indicating a request to change a parameter associated with a transaction, the application server comprising a heterogeneous pricing and payment system that comprises a price engine component, an order adjustor component, and an order presenter component communicatively coupled via at least a shared memory;
• based on detecting the edit, delaying, via the price engine component included in the application server implemented by the at least one hardware processor, processing of the edit until initiation of a checkout process associated with the transaction is detected, the parameter corresponding to a currency type, the delaying of the processing reducing network resource consumption by consolidating changes to the parameter affecting a result value of transaction into a unified transaction step for display;
• in response to detecting the initiation of the checkout process associated with the transaction, processing, via the price engine component and the order adjustor component included in the application server implemented by the at least one hardware processor, the edit including generating the result value based on a changed parameter associated with the transaction, the order adjustor component aggregating changes to the parameter calculated on a computer logic level by the price engine component and determining the result value of the transaction based on the aggregated changes to the parameter;
• and
• causing, by the order presenter component included in the application server implemented by the at least one hardware processor, display of the result value in a checkout user interface on a display component of the client device.
