- Workforce
- Pay types and work states. Each adds tax rules and filings a provider must handle.
- Payroll operation
- Pay schedules, off-cycle runs and how changes reach payroll, where errors get in.
- Service needs
- Self-service, reliable live help, a dedicated contact or managed payroll administration. Each puts the work in different hands: a support line isn’t someone managing your payroll. Broader HR, ASO or PEO-style help is explored separately from an ordinary payroll-software comparison.
- Connected systems
- Timekeeping, accounting and benefits tools. A weak handoff means rework every pay period.
- Must-haves and constraints
- What a provider must do now, and the limits you’re working within.
- Priorities and preferences
- What matters most when several providers can do the job. These separate close options without overriding a must-have.
- What you’re not sure about
- Answer Not sure or skip. If the gap could change which providers fit, InsiderMatch asks again.
