Every “best payroll software” list looks the same: a handful of big names ranked by who paid for placement. Instead of ranking competitors, here’s what should actually drive your decision.

Pricing structure. Most payroll software charges a base monthly fee plus a per-employee fee. Watch for hidden costs like tax filing fees, year-end W-2/1099 charges, or extra fees for multi-state payroll.

Automatic tax filing. The single biggest time-saver is software that calculates, files, and pays your federal, state, and local payroll taxes automatically — and guarantees accuracy.

Integrations. Your payroll tool should connect cleanly with your accounting software (QuickBooks, Xero), time tracking, and benefits providers so you’re not re-entering data.

Ease of setup. Look for software that lets you go live without a phone call to a sales rep. If a “quote” is required just to see pricing, that’s often a signal of a longer, more expensive onboarding process.

Support when something goes wrong. Payroll mistakes are costly. Real-time chat or phone support — not a 48-hour ticket queue — matters more than most buyers realize until they need it.

Mobile access. More small business owners are running payroll from their phone between other tasks. A true mobile app, not just a mobile-friendly website, is increasingly a baseline expectation.

Why Onyx fits small businesses specifically: flat, transparent pricing with no surprise tax-filing fees, automatic multi-state compliance, and a mobile app built for owners who don’t have an HR department.
