On-Demand Payroll Microservice for Real-Time Unscheduled Payments

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional payroll systems are batch-based and do not support real-time or on-demand payroll calculations, leading to delays in processing unscheduled payments such as bonuses, commissions, or adjustments, and lack compliance with tax deposits and garnishment settlements.

Innovation Solution

An on-demand payroll microservice retrieves payroll information from a first set of microservices, performs calculations using a second set of microservices, and displays results in near real-time, allowing for immediate approval and processing of unscheduled payments, utilizing a microservice architecture and machine learning for dynamic policy application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional batch-based payroll systems are used, then payroll processing follows predetermined schedules, but unscheduled payments cannot be processed in real-time

Engineering Contradiction:

Improvepayroll processing speedVSAvoidflexibility for unscheduled payments

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The payroll system is divided into independent microservices including on-demand payroll microservice, calculation microservices, and processing microservices. This segmentation allows the on-demand payroll functionality to operate independently from the traditional batch processing schedule, enabling real-time unscheduled payments while maintaining existing payroll operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from static batch-based payroll processing to dynamic on-demand processing. The on-demand payroll microservice can initiate payroll calculations and processing at any time based on actual needs, making the system adaptable to unscheduled payments while maintaining the ability to process according to predetermined schedules when appropriate.

Inventive Principle:

Principle #15Dynamics

2Loss of time

If on-demand payroll processing is implemented, then real-time calculations are enabled, but system complexity increases

Engineering Contradiction:

Improvewait time for payroll processingVSAvoidsystem architecture complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

An on-demand payroll microservice acts as an intermediary layer between the user interface and the existing payroll infrastructure. This microservice receives on-demand requests, coordinates with calculation microservices and processing microservices, and manages the workflow, thereby hiding the underlying system complexity from users while enabling real-time processing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The microservice architecture creates universal components that can handle both traditional batch payroll processing and on-demand unscheduled payments through a common interface. The calculation microservices and processing microservices serve multiple purposes, reducing the need for separate dedicated systems for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If microservice architecture is used for on-demand payroll, then real-time processing is achieved, but integration complexity with existing systems increases

Engineering Contradiction:

Improvepayroll processing efficiencyVSAvoidmicroservice integration complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The implementation introduces a partial microservice architecture rather than completely replacing the existing payroll system. The on-demand payroll microservice integrates with specific components of the existing system (calculation and processing microservices) while leaving the core batch processing infrastructure intact, thereby achieving real-time processing capability without requiring full system restructuring.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method, apparatus, system, and computer program product for processing an on-demand payroll request. In one illustrative example, an on-demand payroll microservice receives a request for an unscheduled payroll for an employee. The on-demand payroll microservice retrieves payroll information for the employee from a first set of microservices. The on-demand payroll microservice submits the payroll information to a second set of microservices for payroll calculations. In response to the second set of microservices completing the payroll calculations, the on-demand payroll microservice retrieves the payroll calculations through the first set of microservices. The on-demand payroll microservice displays the payroll calculations. In response to receiving approval of the unscheduled payroll, the on-demand payroll microservice submits the payroll calculations to the second set of microservices for payroll processing. In response to the second set of microservices completing the payroll processing, the on-demand payroll microservice displays a confirmation of the payroll processing.
