A radiology tech whose ARRT certification lapsed three weeks ago is still showing up on the schedule. They're being paid. Nobody flagged it because the payroll system doesn't know what an ARRT certification is, let alone when it expires. That's not a hypothetical, it's what happens when labs and imaging centers run workforce management on platforms built for general industry rather than credentialed clinical environments.

Payroll accuracy matters everywhere. In labs and imaging centers, credential accuracy carries patient safety implications on top of it.

Why the Healthcare Payroll Market Is Growing at 11 Percent

The payroll software market in healthcare is projected to grow from $1.12 billion in 2025 to $2.10 billion by 2031. Labs and imaging centers are part of that growth because the compliance environment has become too layered for generic platforms to manage cleanly. The 2024 Change Healthcare breach raised data security standards across the sector. The 2026 Medicare Physician Fee Schedule updates require real-time compensation recalibration that older batch-processing systems can't keep up with. The platforms that were good enough five years ago aren't good enough now.

The 5 Best Payroll Software Platforms for Laboratory and Diagnostic Imaging

1. Netchex : Best Overall for Lab and Diagnostic Imaging Operations

Netchex's healthcare vertical was built for clinical workforce complexity, not adapted from a retail or office-based platform. For a lab or imaging center managing credentialed technologists, per-diem staff, overnight differentials, and multi-site operations, that distinction matters practically in every pay cycle.

Credential and certification tracking is integrated directly into the HCM platform,not in a separate spreadsheet, not in a different system that someone manually cross-references before the schedule goes out. Licensing status sits alongside scheduling and payroll data. Expiration alerts fire before a lapse happens rather than after someone has already been scheduled and paid through a compliance gap. For labs with state-varying licensure requirements across multiple sites, this is the feature that eliminates the most risk.

Shift differentials for nights, weekends, and holidays process natively inside the payroll run without manual rate entry each cycle. Per-diem staff run in the same payroll as full-time and part-time employees without requiring separate processing. ACA eligibility is tracked automatically for variable-hour workers, which in a lab environment often includes a significant portion of the support staff. The full employee lifecycle: hiring, onboarding, time, payroll, benefits, performance, and compliance, runs under one login, which reduces the administrative load for lean HR teams managing a credentialed workforce across multiple sites.

Data handling is HIPAA-compliant. The learning module includes over 2,000 compliance courses with healthcare-specific content. Support picks up in under a minute from a U.S.-based team with healthcare experience. Thousands of healthcare organizations use Netchex across the clinical spectrum.

The Colony ER Hospital's chief administrator described the support experience directly: "I feel as though I am the only customer at times because I have immediate assistance whenever I need it."

2. ADP Workforce Now : Good for Large Multi-Site Lab Systems

Large laboratory systems with complex multi-state organizational structures and dedicated HR and IT staff will find ADP Workforce Now's compliance depth and configurability genuinely useful. The integration marketplace is broad and multi-state tax handling is solid. Healthcare-specific features, credential tracking, clinical pay structures, per-diem handling, require configuration rather than working natively, and the support model doesn't reflect clinical workforce expertise.

Good for: Large multi-site laboratory systems with a dedicated HR and IT function.

3. UKG Pro : Good for Complex Healthcare Workforce Scheduling

UKG's depth in shift rotation, coverage management, and scheduling rules across multiple clinical sites is real and difficult to match. For larger healthcare organizations where workforce scheduling is its own operational challenge, that depth is meaningful. For a mid-size lab or imaging center without dedicated HR staff, the implementation investment and ongoing platform management are more than the operation requires.

Good for: Larger healthcare organizations where scheduling complexity across multiple clinical sites is the primary challenge.

4. Paycor : Good for Growing Healthcare Groups

Paycor has a cleaner interface than most enterprise platforms and can do multi-location healthcare payroll without a technical HR background. Good compliance tools and not too high learning curve. There is upfront setup work for any lab environment that has complex licensure requirements because credential tracking and clinical pay structures need to be configured at setup, not out-of-the-box.

Good for: Growing healthcare groups adding sites who need reliable multi-location payroll without enterprise-level complexity.

5. Workday : Good for Large Integrated Health Systems with Lab Operations

Where Workday earns its cost is in large integrated health systems where labs are one component of a broader enterprise, analytics, financial system integration, and workforce planning at scale are all genuinely powerful at that level. For a standalone lab or imaging center, the implementation investment and total cost of ownership relative to what mid-market platforms deliver make the decision fairly clear.

Good for: Large integrated health systems where lab operations are one part of enterprise-scale HR and finance management.

Quick Comparison Table

Lab Payroll Has Clinical Stakes That Generic Platforms Miss

Credentialing gaps, shift differential errors, and per-diem complexity don't get absorbed quietly in a lab environment. Netchex was built for healthcare workforces, the credential tracking, the pay structures, and the compliance layer are all native rather than configured after the fact.

Frequently Asked Questions

1. How does credential tracking actually work, where does the data live?

In Netchex, certifications and license expiration dates are stored inside the HCM platform alongside the employee's scheduling and payroll records. There's no separate tracking spreadsheet to maintain and no manual cross-referencing before the schedule goes out. When a license is approaching expiration, the system fires an alert rather than waiting for someone to notice.

2. Per-diem imaging staff and full-time employees on the same payroll run, is that actually clean?

Netchex handles mixed workforces within the same payroll run without separate processing or manual rate adjustments. Per-diem, part-time, and full-time employees process together with the correct rules applied to each. Labs that switched from platforms requiring separate per-diem processing typically find this one of the most immediate time savings.

3. How does ACA compliance work for variable-hour lab support staff?

Netchex tracks hours against ACA eligibility thresholds automatically for every variable-hour employee. When someone is trending toward coverage-required status, you get a flag before they cross the threshold. In lab environments where a significant portion of support staff work variable hours, managing this manually is where compliance exposure tends to build quietly.

4. What does HIPAA compliance mean in the context of a payroll platform?

For Netchex specifically, it means employee data - including health and benefits information - is handled, stored, and transmitted in accordance with HIPAA standards. For labs and imaging centers that are already operating under strict HIPAA requirements, using a workforce platform that meets the same standards matters both for compliance and for the audit trail.
