Switching payroll and workforce management software is a critical decision that impacts compliance, payroll accuracy, and employee satisfaction. Sales teams make impressive promises, but implementation often tells a different story. To ensure a smooth transition, companies must conduct thorough testing, verify support responsiveness, and never trust blindly. Below are essential best practices, pitfalls to avoid, and red flags to watch for.
Assess Your Needs Beyond Sales Promises
Identify must-have features and compliance requirements.
Don’t rely solely on vendor ratings—request a trial period to evaluate both software functionality and support response times.
Focus on key business policies that have been difficult to automate in the past, and request tailored demonstrations to verify automation capabilities.
Ensure the system handles taxes, benefits, and payroll complexities correctly.
Vendors must show you, rather than simply make claims that may or may not be true after you have signed a contract—details matter. Consider creating examples of the most complex scenarios and asking them to demonstrate exactly how their system handles those situations.
Ensure Data Accuracy and Completeness
Migrate clean and validated payroll data.
Verify tax codes, employee classifications, and payroll deductions.
Double-check compliance settings, including unemployment and state tax rates.
Conduct Rigorous Parallel Payroll Runs
Run at least two parallel payrolls before going live. The first should identify errors, and the second should be error-free.
Continue parallel runs until no discrepancies remain and both parties are fully confident in the system’s accuracy.
As the employer, you bear ultimate responsibility—regardless of vendor assurances.
Payroll errors will lead to frustrated employees, and you will be responsible for resolving them.
Maintain control over the timeline—don’t let the vendor dictate when you’re ready to go live.
Engage Stakeholders Early and Set Clear Expectations
Involve payroll administrators, HR, finance, and IT from the beginning.
Provide comprehensive training to all users.
Establish clear timelines to prevent confusion and ensure a structured rollout.
Demand Proof of Reliable Vendor Support
Answers to sales questions are one thing, but you also need to test how the vendor handles support issues.
Measure response times, hold times, and how quickly resolutions are made.
A trial period helps with this—use it to gauge both the software and the vendor’s responsiveness before signing a contract.
Ensure a clear escalation path exists for urgent payroll issues.
Track how quickly actual resolutions are provided, not just how fast responses are received.
Skipping Parallel Payroll Runs
Payroll errors can lead to tax penalties and employee dissatisfaction.
Some vendors may push for an immediate go-live before you are fully ready—insist on thorough testing and validation instead. Even if the go-live date was agreed upon earlier, do not proceed until you are confident in the system’s accuracy and reliability.
Ignoring Tax Compliance Settings
Misconfigured tax settings can result in under- or over-withholding.
Ensure state and federal tax rules are correctly applied, including employer-only taxes that can often be overlooked.
Inadequate Training
Payroll and HR teams must be trained to prevent costly errors.
Employees should understand how to access pay stubs and tax documents.
Underestimating Vendor Support Quality
Slow responses and unresolved issues can cripple payroll processing.
A vendor’s sales team is not the support team—evaluate actual support before committing.
Poor Data Migration Practices
Incomplete or incorrect data transfers cause payroll discrepancies.
Validate all historical payroll data before transitioning.
Slow or Unresponsive Support
If a vendor takes days to respond during onboarding, expect delays post-implementation.
Lack of a dedicated support representative can indicate service issues.
Lack of Transparency in Implementation Timeline
Vendors should provide a clear, detailed implementation plan tailored specifically to your requirements.
A rushed or vague go-live process often leads to major payroll errors.
Failure to Deliver on Promised Features
Some vendors claim full automation but fall short when it matters.
Ensure critical functions like tax filings, direct deposits, and reporting work as expected.
Pushing a Go-Live Without Parallel Runs
Vendors may dismiss the need for testing—this is a major red flag.
Without parallel runs, errors will only become visible after payroll goes live.
High Costs Without Premium Service
If a vendor charges premium prices but fails to resolve issues quickly, reconsider the partnership.
A payroll transition gone wrong underscores the need for rigorous testing and vendor accountability. A company was promised full automation and seamless HR integration, only to face the following problems:
Unemployment tax setup errors caused incorrect filings for months.
Holiday pay misconfigurations led to manual corrections and payroll delays.
Unresponsive support stretched issue resolution into weeks.
Disorganized ticket handling resulted in multiple representatives providing conflicting answers.
No parallel payroll testing meant issues surfaced only after employees were paid incorrectly.
Despite high ratings and strong initial sales engagement, the company found that the vendor could not deliver as promised. After months of frustration and financial loss, they had to reconsider their payroll strategy. The key lesson? Test everything yourself—don’t take promises at face value.
A payroll transition is more than just software implementation—it’s about ensuring compliance, accuracy, and ongoing support. Sales teams can make anything sound perfect, but real-world execution matters. Always demand proof, test thoroughly, and never trust blindly. Payroll is too important to get wrong.
