Direct comparison frameworkHow to compare payroll software
Start with the work your company must complete, not a provider's feature count. Document your worker types and locations, identify who owns each filing and correction, calculate the full first-year cost, and require each finalist to demonstrate the same sample payroll workflow. The table below turns those requirements into evidence you can compare across vendors.
| Comparison area | Evidence to collect | Warning sign |
|---|
| Worker coverage | Employees and contractors by state or country, pay schedules, benefits, and local registration needs. | A broad coverage claim without written confirmation for your exact worker mix. |
| Filing responsibility | Federal, state, and local filings; payment timing; notice handling; amendment and year-end form ownership. | The contract or demo does not distinguish provider work from employer responsibility. |
| Total operating cost | Base fee, per-worker charges, contractor fees, add-ons, implementation, support, migration, and year-end costs. | A low headline price that excludes required modules or implementation work. |
| Implementation | Prior payroll import, parallel run, cutover owner, tax account setup, first payroll date, and rollback plan. | No named owner or written timeline for data validation and the first live run. |
| Support and controls | Approval roles, audit history, correction workflow, escalation path, response targets, and export access. | Only general support promises when a payroll deadline is blocked. |
| Accounting ecosystem | General ledger mapping, time and benefits integrations, API or export formats, and reconciliation workflow. | An integration exists in marketing material but cannot reproduce your accounting handoff. |
Practical test: Give two finalists the same fictional payroll scenario. Ask each to show employee setup, contractor handling, payroll preview, one correction, accounting export, and support escalation. Keep screenshots or written answers without entering real employee, tax, bank, or wage data.
