We compared Gusto against alternatives for a multi-month payroll scenario at a 12-person startup, then switched to ADP when we hit 50 employees across 3 states. We've also processed representative payroll workflows in Paychex, Paylocity, Paycor, and QuickBooks Payroll to compare setup time, tax filing accuracy, and actual cost per employee. The biggest surprise: "custom pricing" often means 30-50% more than published competitors once you add required modules.
Editor’s take: Our shortlist: if you only have time to evaluate two, start with the top pick on this list and the runner-up. The other three are good, but you'll make the right call after looking at those two seriously.
Payroll is the one HR system where being wrong has immediate consequences, so the decision should weight accuracy and filing support above interface polish. Check how the platform handles your jurisdictions and whether it files and remits taxes on your behalf. Migration mid-year is painful, so if you are considering a switch, time it to a quarter or year boundary.

Payroll software is judged on accuracy first and everything else second, so we weighted five dimensions that determine whether a pay run goes smoothly every cycle:
1–20 employees: Prioritize ease of use and transparent pricing. You do not need enterprise features yet. Tools like Gusto and Justworks are designed for this stage.
20–100 employees: You need a proper HRIS now. Employee records, time-off tracking, and compliance reporting become real needs — not nice-to-haves. BambooHR and Rippling are strong at this stage.
100–500 employees: Performance management, advanced reporting, and integrations matter more. You likely have dedicated HR staff now. HiBob, Paylocity, and ADP Workforce Now are worth evaluating.
500+ employees: You need enterprise-grade compliance, global payroll, and workforce planning. Workday and SAP SuccessFactors are the established players at this level, though Rippling is making inroads.
The best payroll depends on your team size, budget, and priorities. Startups and small businesses often prefer tools with transparent pricing and quick setup, while larger organizations need advanced reporting, global compliance, and dedicated support.

Each payroll platform was scored on five criteria: ease of use (25%), feature depth (25%), pricing transparency and value (20%), support quality (15%) and scalability (15%). For payroll specifically, feature depth means tax filing coverage, multi-state handling and year-end processing rather than a long feature list. Gusto, ADP Workforce Now, Paychex, Paylocity and Paycor all clear that bar; what separates them is how much of the work you still end up doing by hand.
Accuracy came first: each was weighted on whether a pay run completes cleanly every cycle, then on ease of use and feature depth at 25 per cent each, pricing transparency at 20, and support quality and scalability at 15 each. Gusto publishes its rates while the other four quote, so every comparison needs a written quote to be meaningful.
Gusto is the only one that publishes, at $40 per month plus $6 per employee, which makes it the cheapest to evaluate and usually the cheapest to run at small headcount. Paycor is estimated at $8 to $15 per employee per month and Paylocity at $10 to $20, both by quote rather than rate card.
Gusto, and it is not close for a company of one or two: published pricing, no implementation project, and it files the taxes for you. Paychex is worth considering if you would rather have a specialist handle it, but you will pay more for that arrangement.
Paylocity, because its interface and self-service hold up as headcount grows and employees start using the product themselves. ADP Workforce Now is the answer if multi-state or union payroll is the hard part, and Paycor if you need reporting and time tracking depth.
Payroll is not just paying people on time. The harder part is the federal, state, and local tax compliance that surrounds every paycheck. Federal income tax withholding, Social Security and Medicare contributions, federal unemployment tax, state income tax withholding (in states that have it), state unemployment tax, state disability insurance (in the handful of states that require it), and local taxes (in cities like New York, Philadelphia, and San Francisco) all need to be calculated correctly, withheld correctly, remitted on the right schedule, and reported on the right forms. The IRS audits payroll records going back three years, and the penalties for missed deposits, late filings, and incorrect calculations add up quickly.
The strongest payroll platforms handle the full tax compliance stack: they calculate withholding based on the latest IRS Publication 15-T tables, they file federal and state forms automatically on the right schedule, they remit withheld taxes via EFTPS on the due dates, and they generate W-2s and 1099-NECs at year end without manual work. The weaker platforms handle the paycheck calculation but leave tax filing to you, which means you are running payroll tax compliance in a spreadsheet, and any mistake becomes your problem to fix.
For most small businesses, the calculus is straightforward: a payroll platform that handles tax compliance end to end costs $40-80 per month plus a per-employee fee. A bookkeeper or accountant who handles the same work costs $200-500 per month. The platform is almost always the cheaper option for businesses under 50 employees, and the time savings are real. The exception is businesses with complex compensation (multi-state payroll, equity, expat employees, contractors in multiple countries) where the platform costs more in configuration time than it saves in labor.
Most US employees expect direct deposit, and most payroll platforms default to two direct deposit splits per employee (typically 80% to checking, 20% to savings, or whatever split the employee configures). The platforms handle the ACH transfer automatically, and the funds clear in the employee's account by the pay date. For employees without bank accounts, pay cards (prepaid debit cards funded by payroll) are a workable alternative that most platforms support, and a small number of states have passed laws requiring pay card enrollment to be opt-in rather than opt-out.
Paper checks are still legal in every state, but they cost $2-5 per check when you factor in the check stock, the printing, the envelope, and the postage. For a 50-person company running biweekly payroll, paper checks add $5,000-13,000 per year in administrative cost on top of the platform fee. The case for switching to direct deposit or pay cards is almost always about cost, and most platforms make the switch straightforward by handling the employee enrollment directly through their self-service portal.
The compliance landscape around payment methods is shifting. Several states have passed or are considering laws that require written consent before employees can be paid via pay card, and a few have moved to require direct deposit opt-in rather than paper check default. The platforms have kept up with the rule changes, but if you are running payroll in a state with active payment-method legislation, the platform's compliance team is a better source of current rules than any general guide.
Year-end payroll processing is the test that separates robust platforms from the rest. The work involves generating W-2s for every W-2 employee, 1099-NECs for every contractor paid $600 or more, reconciling all tax filings against the actual payroll run, and submitting the year-end federal and state forms on the right schedule. The strong platforms do most of this work automatically and surface what needs human review in a checklist. The weak platforms require manual generation of the forms, manual reconciliation, and manual filing.
The deadline pressure on year-end processing is real. W-2s must be delivered to employees by January 31 and filed with the SSA by the same date. 1099-NECs must be delivered to contractors by January 31 and filed with the IRS by the same date. Federal quarterly forms (941) are due by the end of the month following the quarter end. State forms have their own deadlines, which vary by state. Missing a deadline triggers penalties, and missing several triggers an IRS audit that no small business wants.
For most small businesses, the right approach is to start year-end processing in mid-December. Review the year-to-date totals for accuracy, fix any employee classification issues (W-2 vs 1099), make sure all contractor information is current, and run a draft of the W-2s and 1099-NECs to catch errors before they go out the door. The platforms that surface a year-end checklist in November, rather than waiting for the user to ask, are the ones worth using.
