Imagine your payroll employee spending 6 months per year fixing mistakes. Actually, you don't have to imagine – it's likely already happening.

On average, a full-time payroll employee spends about 29 weeks per year correcting errors, which translates to over half a year of lost productivity. Employers can spend up to 26 minutes per employee correcting each payroll discrepancy, which adds up quickly in larger organizations. 49% of HR teams report spending five or more hours per month correcting payroll errors.

According to PayCom:

  • Businesses lose roughly 440 hours (about 11 workweeks) fixing faulty time punches annually. 
  • An average of 257 hours is spent addressing erroneous expenses.
  • Organizations spend 135 hours correcting unentered sick time.
  • About 130 hours are lost correcting health savings plan miscalculations.

How much payroll inefficiencies cost?

None of financial institutions managed to calculate it. According to Ernst & Young, a single payroll error costs a business an average of $291. Given that 20% of payrolls contain errors, this can lead to terrible financial losses for organizations.

To make an educated guess on the global cost of payroll errors, we need to consider several factors and use the available data to extrapolate a reasonable estimate. Let's break this down step by step:

  1. Cost per error: We know that a single payroll error costs an average of $291 1.
  1. Error rate: 20% of payrolls contain errors 1.
  1. Global workforce: The International Labour Organization estimates the global workforce at approximately 3.3 billion people.
  1. Payroll frequency: While this varies globally, let's assume an average of 24 payroll runs per year (considering a mix of weekly, bi-weekly, and monthly payrolls).
  1. Formal employment: Not all workers are in formal employment systems with regular payroll. Let's conservatively estimate that 60% of the global workforce is processed through formal payroll systems.

Now, let's calculate:

  1. Number of employees in formal payroll systems: 3.3 billion * 60% = 1.98 billion
  1. Total payroll runs per year: 1.98 billion * 24 = 47.52 billion
  1. Number of payroll runs with errors: 47.52 billion * 20% = 9.504 billion
  1. Total cost of errors: 9.504 billion * $291 = $2,765,664,000,000 (approximately $2.77 trillion)

This estimate suggests that globally, approximately $2.77 trillion could be wasted annually due to payroll errors alone.

Payroll challenges

It's not easy to keep employee paychecks accurate and precise, especially when your organization employs tens of thousands of them. Yet, you have to do it. Fines aside, according to the Workforce Institute, 49% of employees would consider leaving their job after just two payroll errors, and 24% would begin looking for another job after just one error.

Accuracy and underpayment

The overall mean accuracy of payroll processes is just 78%, up only slightly from 75% last year. A third (32%) of organizations need at least two pay cycles to resolve underpayments, while 22% encounter mid-cycle issues that require supplementary runs and tax recalculation.

Sensitive data management

You have data management issues when employee information is incomplete or inaccurate. That compromises payroll integrity.

What's more, payroll contains sensitive data, which is attractive to cybercrime. Data breaches affecting payroll are common, with 60% of respondents reporting a cyber breach in the last 24 months.

Calculation complexities

There is a 91% complexity gap between the most and least complex payroll countries. Managing payroll across multiple countries involves dealing with diverse payment schedules, tax laws, and compliance requirements. 75% of respondents in a survey manage payroll in up to 25 countries, increasing the complexity of ensuring accurate and timely payments.

Foreign exchange discrepancies affect 18% of payroll payments, potentially reducing accuracy and increasing financial risks.

Additionally, 15% of businesses use more than 11 payment providers globally, leading to inefficiencies and compliance risks. 66% of payroll professionals lack tools to understand their current costs with banks and payment providers.

Time-tracking

Small errors in tracking employee hours or calculating overtime and you have compliance problems. Inaccurate time tracking can result in financial losses due to overpayment or underpayment of employees. In the construction industry, for example, businesses could lose up to 5% of their profits due to time tracking inefficiencies

Time pressure

Time constraints add pressure on payroll teams. They have to get it right and meet deadlines. The complexity increases when you have different types of workers with varied pay structures.

Regulatory compliance

Regulatory compliance is a big headache. Tax laws change constantly and you have to monitor and adjust your processes. 61% of businesses cite legal and regulatory compliance as their biggest challenge in global payroll management.

Non compliance means financial penalties and damages your company’s reputation. When you operate across multiple locations, these challenges multiply. Each location has different tax laws and payroll regulations.

Business rules engines as a solution

Business rules engines (BRE) are the solution to these problems. These systems partially automate decision-making by applying pre defined rules to payroll data. They separate business logic from application code, so it’s easier to maintain and update rules.

BREs handle complex calculations and compliance with changing regulations. They reduce manual processes and human error in payroll. These engines integrating with existing systems and maintains consistency of rule application across your organization.

Implementing a BRE changes your payroll process. The system captures and codifies all business rules in a central repository. That makes them accessible to authorized users while secure. Non-technical users can manage rules through user-friendly interfaces, so you don’t need to depend on IT departments.

The execution engine applies these rules to business data in real time. It evaluates information against defined rules and perform automatic calculations. Administration tools manage user permissions and access, so only authorized people can modify sensitive rules.

Use cases for Business Rules Engines in payroll management

Use cases for BREs in payroll management

How can you use this payroll technology? Here are some inspirations:

  1. Automating Complex Calculations: BREs can handle intricate payroll calculations, including wages, overtime, and various deductions based on predefined rules. This is particularly useful for organizations with complex pay structures or those operating across multiple jurisdictions.
  1. Ensuring Regulatory Compliance: BREs can be programmed to automatically apply and update rules based on changing labor laws and regulations. This is crucial for maintaining compliance and avoiding penalties.
  1. Handling Multi-country Payroll: For multinational organizations, BREs can manage country-specific payroll requirements, ensuring compliance with local regulations and generating appropriate reports.
  1. Integrating Time and Attendance: BREs can seamlessly integrate time and attendance data with payroll systems, ensuring accurate payment for hours worked, including overtime and breaks.
  1. Preventing Payroll Fraud: By implementing strict validation rules and checks, BREs can help detect and prevent payroll fraud, such as identifying ghost employees or unauthorized changes to payroll records.
  1. Streamlining Payroll Reconciliation: BREs can automate the reconciliation process, helping to identify and correct errors in payroll processing efficiently.

Higson Real-World Example: Simplifying Payroll Rules Across Jurisdictions

A real-world implementation highlights how a business rules engine can address the complexities of payroll operations. Neo Intelligence, an Australian software provider for the construction industry, faced a growing challenge: managing highly diverse payroll regulations across multiple states and individual client rules. By implementing Higson, Neo Intelligence centralized all payroll rules into a unified, manageable system. Business users now define and modify rules via decision tables, without needing technical support, and the engine automatically applies the right rules for each jurisdiction and contract type. This setup not only improved calculation accuracy and compliance but also drastically reduced manual processing time. The solution allowed the organization to keep pace with frequent legal changes while maintaining a consistent and auditable payroll logic.

Key Benefits of using BRE in payroll

Automating payroll with business rules engines gives you many benefits. You increase operational efficiency by automating manual processes. You save time and reduce administrative burden for payroll administrators.

Calculation accuracy improves. The system calculates precise amounts, no human error in payroll calculations. That extends to tax filing and compliance reporting, so you reduce compliance risks.

BREs give you more agility. When regulations change, you adjust rules without expensive software changes. This agility helps your organization to respond faster to new legal requirements.

Integration capabilities allow BREs to work with existing systems seamlessly. That creates a unified payroll ecosystem, connecting employee data across multiple systems. Payroll data flows accurately throughout your organization.

Cost savings comes from multiple angles. You reduce cost to correct errors and non-compliance penalties. Payroll teams focus on value adding activities instead of repetitive tasks. Productivity increases across finance teams and hr departments.

Employee satisfaction improves when they get accurate compensation consistently. They get on time payments with correct calculations. That builds trust and reduces payroll queries.

Do you need to apply changes to your payroll processes? No need to engage IT team and wait for them to clear the backlog. Business Rules Engines allow business users to create, apply and change rules whenever you need to. This way you can be sure you have up to date information, adhering to regulatory requirements.

Partial process automation reduces the need for manual intervention. Decisions are made based on real-time data. Say your employee just filed for a paid leave and it was accepted – your payroll software will automatically track it with the help of BRE.

Do You Want To Streamline Payroll Processes?

Modern payroll software transforms routine payroll tasks into streamlined business processes, reducing the staggering $1.4-2.8 trillion wasted annually through errors and inefficiencies, giving you competitive edge. 

Forward-thinking companies are reimagining their payroll operations through technology that adapts to complex regulations while delivering precision and reliability.
