What is payroll software?
Payroll software helps teams calculate pay, process payroll runs, handle deductions and tax filings, and keep payroll data aligned with employee records and compliance requirements.
What's the best software for payroll?
The best payroll software depends on business size, compliance complexity, contractor coverage, and whether payroll should live inside a broader HR platform. Buyers often compare products like Gusto, ADP Workforce Now, Deel, Paycom, and Rippling rather than relying on a single default pick.
What should small businesses look for in payroll software?
Small businesses should prioritize ease of setup, payroll accuracy, tax support, employee self-service, and how cleanly the product handles benefits, contractors, reimbursements, and exceptions without needing a heavy admin team.
What is the cheapest payroll software for small businesses?
OnPay and Gusto Simple are the most affordable payroll platforms for small businesses, both starting at $49/month plus $6 per worker. OnPay sells a single payroll plan, Payroll Essentials, with optional HR and time-tracking add-ons, which makes it simpler to budget. Gusto Simple covers tax filing and direct deposit but reserves some features (next-day deposit, HR tools) for higher tiers. For businesses already on QuickBooks, QuickBooks Workforce Payroll (formerly Core) starts at $50/month plus $7/employee and integrates directly with your accounting.
How much does payroll software cost per employee?
Most SMB payroll software costs $6–$22 per employee per month on top of a monthly base fee ranging from $35 to $180. For a 50-employee company, expect to pay about $350–$1,300/month depending on the plan. Mid-market platforms use per-employee pricing without a base fee: Paylocity runs an estimated $18–$22 per employee per month for payroll plus core HR, and ADP Workforce Now an estimated $23–$30. Always calculate total annual cost including add-ons like benefits integration, multi-state filing, and same-day deposit, because the base rate rarely reflects the full price.
Is Gusto or Paychex better for small business payroll?
Gusto is better for tech-savvy small businesses that want modern UX, self-service setup, and transparent pricing. Paychex is better for businesses that want a dedicated payroll representative and managed services. Gusto handles most setup and configuration through the product itself. Paychex assigns an account representative who helps with onboarding, tax questions, and ongoing support. If you are comfortable with software and want lower cost, choose Gusto. If you want a hands-on service relationship, Paychex is the stronger fit.
Can payroll software handle multi-state tax filing?
Yes, most modern payroll software handles multi-state tax filing, but coverage varies. Gusto, ADP, Paychex, and Rippling support all 50 states. Some platforms charge per-state surcharges for tax filings beyond your home state. Local tax filing (city and county taxes) is less universally supported — verify coverage for specific localities like New York City, Philadelphia, or Ohio municipal taxes. If you have employees in 5+ states, multi-state tax filing capability should be a primary evaluation criterion.
Do I need separate payroll software if my HR platform includes payroll?
It depends on the quality of the built-in payroll. Platforms like Gusto and Rippling include payroll as a core, production-grade module — comparable to standalone payroll software. BambooHR offers payroll as a paid add-on with more limited features. Other HRIS platforms include basic payroll that lacks advanced features like garnishment handling, multi-state filing, or same-day deposit. Evaluate the included payroll module against your specific requirements before paying for a second platform.
How long does it take to switch payroll providers?
For SMB platforms (Gusto, OnPay, QuickBooks Payroll), expect 2–4 weeks from contract signing to first live payroll run. Mid-year switches take longer — add 1–2 weeks for YTD data migration and validation. Mid-market and enterprise platforms (Paylocity, ADP) typically require 4–8 weeks including implementation support, data migration, and parallel payroll runs. The biggest variable is data quality — clean employee records with accurate YTD data migrate quickly, while messy records require significant cleanup.
What is the difference between payroll software and a PEO?
Payroll software is a tool you operate yourself — you configure it, run payroll, and own the employer relationship. A PEO (Professional Employer Organization) becomes a co-employer of your workforce and handles payroll, benefits, workers' comp, and HR compliance as a managed service. PEOs typically charge 3–10% of total payroll cost, which is significantly more than software alone. PEOs make sense for small companies that lack HR infrastructure entirely. Payroll software makes sense when you want control and lower cost.
Can payroll software pay international contractors?
Some payroll platforms handle international contractor payments natively — Deel and Remote are the leaders here, supporting 150+ countries with local compliance, currency conversion, and multiple payment methods. Gusto added international contractor payments as a feature. Traditional platforms like ADP and Paychex focus on domestic payroll and typically require third-party integrations for international payments. If international contractor payments are a regular need, prioritize platforms with native global payment capabilities.
What happens if payroll software files my taxes incorrectly?
If your payroll software miscalculates or files taxes late, the IRS and state agencies assess penalties against your business — not the software vendor. This is why a tax penalty guarantee matters. Vendors that offer this guarantee agree to cover penalties caused by their errors, typically including incorrect calculations and late filings. Not all vendors offer this guarantee, and the terms vary. Read the fine print: some guarantees cap at a dollar amount, exclude late filing caused by missing employer data, or only apply to certain tax types.
How do I run payroll for the first time with new software?
First, complete setup: enter your company tax information, register with state agencies (or verify the vendor handles this), add all employees with correct W-4 elections and bank accounts, and configure your pay schedule and deductions. Then run a test payroll — most platforms let you preview calculations before committing deposits. Verify every employee's gross pay, deductions, tax withholdings, and net pay. If switching mid-year, confirm that YTD data is loaded correctly. Only approve the live payroll run after the numbers check out.
What is the difference between domestic and global payroll software?
Domestic payroll software handles payroll, tax filings, and compliance for employees in a single country (usually the US). Global payroll software handles multi-country payroll, in-country tax compliance, statutory benefits, and local bank transfers. If you have employees in more than one country, domestic payroll software will not cover the legal requirements in those markets. Global platforms like Deel, Remote, Papaya Global, or Rippling Global are built for multi-country payroll. For small headcount in a foreign country, an Employer of Record (EOR) is often more cost-effective than standing up global payroll infrastructure.
What specific US regulations does payroll software handle?
A proper payroll platform handles FLSA overtime calculations, federal and state income tax withholding, FICA contributions (Social Security and Medicare), FUTA and state SUTA unemployment taxes, W-2 and 1099 generation, and wage garnishments. State-specific laws — like California's final paycheck timing, weekly pay frequency requirements in some states, and tip pooling rules — should be handled automatically, not require manual configuration. Always verify that your payroll platform covers your specific states before committing.
