The Ultimate Guide to Payroll Integrations

Almost half (49%) of HR professionals use seven or more different software products every day to manage their workforce. These systems are rarely able to communicate with each other, which means the data often differs slightly in each database—unless the HR team manually updates each system daily—making it difficult for employers to get a comprehensive overview of their workforce. Fortunately, there’s a better way: payroll integrations.?

From streamlining pay to keeping retirement benefits up-to-date and efficiently managing benefits enrollment and deductions, payroll integrations enable the faster, more accurate workflows that HR professionals want.?

In this guide, we’ll look at payroll integrations in detail—including common use cases, benefits, and challenges—as well as how they’re commonly built and maintained.?

What are payroll integrations?

Payroll integrations are a means of connecting payroll systems to the other HR, benefits, and fintech solutions HR teams use to manage their workforce. Built on APIs, payroll integrations automate the exchange of data between the employer’s primary source of truth (the payroll system) and other applications, so the information held in each system is always accurate and up to date.??

As payroll processing becomes more complex, API payroll integrations offer a range of benefits, including easier access to accurate data, automation, and more intuitive workflows.

Common use cases for payroll API integrations

From managing 401(k) plans to streamlining tax compliance, payroll API integrations optimize various HR and administrative functions, enhancing efficiency and accuracy. Typical use cases for these integrations include:

401(k) and retirement

By integrating with payroll systems, 401(k) recordkeepers and third-party administrators (TPAs) can streamline sponsor onboarding, automate retirement plan enrollment, easily manage deductions, and access all the information required for yearly record-keeping audits.?

HR tech

HR tech platforms are supposed to integrate with a company’s existing systems—but with so many payroll providers, that’s not always feasible. With an API-based payroll integration, there’s no need to update employee data across systems—it’s synced automatically.

Employee benefits

Benefits platforms rely on frequent, manual updates, often leading to errors and delays. Using a payroll integration helps employers onboard new hires, enroll them in any benefits programs, and automatically manage deductions.

Insurance

Insurance carriers need accurate and up-to-date company and employee data when providing quotes, underwriting policies, and managing claims. Integrations allow carriers to access the data held in employer systems of record.?

Tax and compliance

Up-to-date information is also crucial for tax and compliance platforms, but collecting this data is labor-intensive and manually sharing that data can often produce errors. Payroll integrations allow instant access to critical employee data in near real time.?

Benefits of payroll integrations

Payroll integrations bring numerous benefits, from saving time and eliminating data silos to enhancing the employee experience. Here's a closer look at how they benefit various stakeholders, including app developers, employers, and payroll providers:

Benefits for application developers

• Improves access to high-quality data: Your potential customers have had enough of dealing with out-of-date, inaccurate data. But they also want to know that their data is in safe hands. Payroll integrations can reduce compliance risks by only collecting strictly necessary data directly synced from employer systems of record—not via email or other unsecured channels. By pulling the data automatically, your application can build automated workflows to expedite payroll processing, increasing the likelihood of meeting Service Level Agreements (SLAs).?
• Simplifies workflows: Streamlined onboarding and an intuitive user experience help your customers achieve a faster time to value. Since they no longer need to manually enter data or switch between multiple applications, they can operate more efficiently and realize a return on their investment much faster.?
• Increases total addressable market (TAM): HR teams don’t want more solutions that can’t integrate with their existing tech stack—they’ve got enough of those. Integrations are now table stakes for them. For employment tech SaaS tools, ensuring your solution integrates with as many payroll systems as possible significantly increases your potential customer base—and ultimately, your revenue.

Benefits for employers

• Reduces administrative burden: Payroll integrations streamline HR tasks, saving valuable time. With 84% of HR professionals emphasizing the importance of tech stack integration, it's clear they spend too much time—up to 10 hours a week—working in disparate employment systems. Integrations free them from mundane data entry, allowing them to focus on HR tasks that require a human touch.
• Improves employee experience: Payroll integrations make it easier to create a comprehensive experience for the employee across all the systems they use to log hours, review pay statements, and manage their benefits, like health insurance and retirement plans. When all of this data is synced across platforms, employees can make changes—like updating their 401(k) contribution, for example—and rest assured that it will be accurately reflected in their next paycheck.?
• Removes data silos: Instead of toggling between multiple applications, integrating payroll systems with other HR applications creates a centralized system for managing employee data. This kind of integrated experience isn’t just more user-friendly—it’s more accurate and efficient, too.

Benefits for payroll providers

• Efficient, reliable connections: Payroll providers are the gatekeepers of mission-critical employee data. Integrations allow these systems of record to freely exchange data with the other applications their customers use. That creates a better experience for the employer and further cements the provider’s role as the primary source of truth for their customers.
