Organizations often trust software to handle critical tasks such as payroll, employee information, and legal compliance. It’s natural to assume that once a system is implemented, it will continue to work flawlessly without much supervision.
However, software is subject to constant updates, configuration changes, and evolving labor laws. Even a small mistake can lead to salary discrepancies, legal violations, or errors in employee information. For this reason, it is essential for technical and compliance teams to regularly test these systems to confirm that everything is working as intended.
Some organizations may assume: we purchased the software from a reputable vendor and configured it correctly. So, the software itself will ensure that the compliance requirements are met.
This may sound right. But there is a big risk involved.
Today’s HR software is not just for paying salaries and checking attendance. Everything from hiring people to performance reviews, compliance with laws, and analytics is now done in a single system. But as processes get bigger, the complexity of the system also increases. When the system gets complex, the chances of mistakes are also high.
For example, consider a situation where employment laws are updated. Companies may need to update their data collection methods, work practices, and employee records to remain compliant with new legal requirements. When the law changes, the software that was set up last year also needs to change accordingly. HR teams should work closely with the vendor’s technical teams to ensure these updates are properly validated.
Instead of relying solely on manual tests or blindly trusting software company updates, HR systems can be tested regularly using modern automation testing tools.
For example, generative AI-powered no-code automation testing tools like testRigor. Unlike traditional software test automation tools, modern AI-powered no-code test automation tools do not demand deep coding skills. They help technical teams create and maintain tests more efficiently using natural language.

Let’s talk about an incident to understand the seriousness of this.
In January 2026, UK supermarket chain Asda had to publicly apologize to its 53,000 current and former employees and agreed to refund all of their lost pay. They ended up in this situation due to an issue with their payroll system.
The company launched a major IT upgrade to modernize its HR systems. They replaced the old Walmart payroll database they had been using with a new, modern HR system. However, a small flaw in the new software caused the system to incorrectly calculate employees’ holiday entitlements and related benefits. This error continued for around 15 months, resulting in tens of thousands of workers receiving incorrect payslips. The company eventually had to hire external auditors to fix the problem. Apart from that, employees also had to receive 12% interest as a form of compensation in addition to the underpaid amounts.
This is the real danger behind the “set it once and leave it” mentality. When companies switch to such complex new HR systems without proper testing by technical teams, a single logic error in the software can affect employees.

The use of HR software has increased significantly due to the current work-from-home and hybrid working models. Employees, managers, and legal teams often rely on such digital systems for important workplace tasks. In this situation, even a small complaint about the software can become a major problem that directly affects the company’s operations and the trust of employees in the company.
HR leaders should ensure that the vendor’s technical teams have a systematic process to check whether their software is working properly when a new update is released, changes are made, or rules change. A single mistake in salary calculation or a minor legal lapse is enough for the company to incur fines and lose employee trust. Regular testing by technical teams is essential to reduce this risk.
Whenever a new update is released for the software, technical teams should review software security. Compliance and legal teams should review regulatory implications. With no-code automation tools, technical and non-technical teams can efficiently automate testing of HR systems, even when complex scenarios are involved. This includes verifying payroll calculations under new laws, proper handling of employee exits, and correct processing of new hire documentation. Organizations should be able to prove that employee data is handled securely by maintaining necessary records.
It’s good to trust the software we use, but it’s even better to ensure technical teams thoroughly test it. Companies looking forward to strengthening compliance should validate their HR systems as part of a broader compliance strategy.

Many HR software providers act as Data Processors when handling employee data on behalf of their customers. But specific responsibilities depend on the contractual and regulatory context. Mostly, employers who own the data are the Data Controllers. Therefore, data processing and data protection are their responsibility.
While you cannot perform technical testing yourself, you are responsible for ensuring that proper testing is conducted by the right teams. Software can contain defects, configuration issues, or unexpected problems that may affect its operation. Software vendors may update their products, features, or service terms over time. But if there is a compliance issue, your company may face legal, financial, or reputational consequences.
Always ensure that technical teams regularly verify the system properly with every new update and every new rule change. It is your responsibility as a business to ensure the right teams are testing and validating the systems you rely on.
