The Best Accounting Software with Payroll for Small Business in 2026

For most small businesses, Xero Growing plus Gusto is the best combination - $55/month for Xero (unlimited users) plus $49/month base plus $6 per employee for Gusto. It is cheaper than QBO Essentials plus QBO Payroll for most team sizes, has bidirectional sync, and Gusto has better HR and benefits features. If you are already on QBO and do not want to migrate, QBO plus QBO Payroll is the most tightly integrated combo.

Xero does not have a standalone US payroll product. For US payroll, Xero partners with Gusto as the primary integration. The Xero-Gusto integration is bidirectional and well-maintained: payroll journal entries auto-post to Xero, new employees sync between systems, and payroll liabilities auto-reconcile. Xero does have payroll built in for Australia, New Zealand, and the UK.

QuickBooks Online plus QuickBooks Payroll has the tightest integration because they are from the same vendor. Journal entries auto-post with the correct accounts, direct deposit uses the same banking setup, and liability tracking is automatic. The tradeoff is cost: QBO Payroll charges $50/month base plus $6 per employee. Xero plus Gusto ($49+$6) is comparable in feature depth and cleaner for multi-user teams.

Pick payroll first. Payroll has more state-level compliance tradeoffs than accounting software - some payroll providers do not support all states for certain features, and switching payroll mid-year is more disruptive than switching accounting. Pick the payroll provider that fits your state, employee count, and benefits needs, then choose accounting software that integrates cleanly with it. In practice, Gusto works with both Xero and QBO well.
