The Payroll Trap Small Teams Fall Into
Here's a scenario that plays out constantly: a business hits its fourth or fifth employee, the owner gets tired of calculating withholdings by hand, and they sign up for the payroll software everyone's heard of. Eighteen months later they're paying $109 a month for a nine-person team, half the features are things they've never opened, and multi-state payroll — which they needed the moment one employee moved across a state line — turned out to cost extra.
That's not a hypothetical. It's the default experience for a huge share of businesses under 10 employees who pick payroll software the same way they'd pick a phone plan: by brand recognition instead of by what they'll actually use. Gusto is the household name in this space, and for good reason — it's polished, well-integrated, and handles complexity well once a company starts scaling. But "handles complexity well" often means "charges for complexity you don't have yet."
OnPay has spent the last few years positioning itself as the answer for exactly this segment: full-service payroll, tax filing, and benefits administration in a single flat plan, with fewer of the add-on toggles that make a Gusto invoice grow every time HR needs something new. For a business with two to nine employees, the choice between them is less about "which is the better product" and more about "which pricing model matches how simple your payroll actually is."
What Each Platform Actually Costs
Pricing details shift often enough that you should verify current numbers on each vendor's site before signing up, but the shape of the comparison has held steady:
Gusto runs a three-tier structure:
- Simple: $49/month base + $6/employee/month — single-state payroll only, basic PTO policies, standard support
- Plus: $80/month base + $12/employee/month — adds multi-state payroll, next-day direct deposit, PTO management, and time tracking
- Premium: $180/month base + $22/employee/month — adds a dedicated customer success manager, HR resource center, and priority support
OnPay runs a single plan: a base fee in the $40–$59/month range plus roughly $6/employee/month, covering full-service payroll, tax filing, benefits administration, and — notably — multi-state payroll at no extra charge.
Run the math on a 6-person business and the gap is modest at the entry tier: Gusto Simple lands around $85/month, OnPay around $75–95/month depending on the exact base rate that month. The gap widens fast the moment you need something Gusto gates behind Plus. A business with even one remote employee in a second state has to jump to Gusto's $80 base tier just to file that employee's taxes correctly — nearly doubling the bill for a feature OnPay includes by default.
Where the Money Actually Goes: Feature by Feature
Multi-state payroll. This is the single biggest cost driver in the comparison. If every employee works in the same state, both platforms handle it at their base price. The moment someone works remotely from a different state — increasingly common even for tiny teams — Gusto pushes you into its Plus tier. OnPay includes it standard.
PTO and time-off tracking. OnPay bundles basic PTO accrual and tracking into its one plan. Gusto reserves fuller PTO management for Plus and above, though its Simple tier does include basic policies.
Next-day direct deposit. A Gusto Plus/Premium feature; Simple-tier customers wait the standard two-to-four-day cycle. OnPay's deposit timing is comparable across the board since there's only one plan to compare against.
Benefits administration. Both charge premium-only pricing for health, dental, vision, and workers' comp — that part is a pass-through cost either way, not a software fee. The difference shows up in availability: Gusto's health insurance marketplace covers roughly 37 states plus D.C., while OnPay offers health insurance brokering in all 50. If your business — or a single remote hire — is in one of the states Gusto doesn't cover, that's a real gap, not a minor one.
Customer support. This is where the reviews diverge most sharply. Independent review aggregators consistently show OnPay's support satisfaction scores running several points ahead of Gusto's (G2 category scores in the mid-9s versus mid-9s-to-low-9s, with a wider gap on Trustpilot). OnPay includes phone, chat, and email support with extended hours at every tier. Gusto's faster or more dedicated support is a Premium-tier perk.
Integrations. Here Gusto wins outright — 100+ integrations including QuickBooks, Xero, and various point-of-sale and time-tracking tools, versus a much shorter list for OnPay. If your business already runs on a specific accounting or scheduling stack, check that OnPay actually connects to it before switching; this is the one place where Gusto's bigger ecosystem is a genuine advantage, not just marketing.
Contractor-only payroll. If you're paying 1099 contractors and no W-2 employees, Gusto has a dedicated Contractor plan starting around $35/month + $6/contractor — worth checking if that's your actual situation, since it sidesteps the employee-tier pricing entirely.
Who Should Actually Pick Which
OnPay tends to fit better if: your team is entirely or mostly W-2 employees, you have (or expect) staff in more than one state, you don't need deep integrations beyond basic accounting sync, and you'd rather pay one predictable number than track which tier unlocks which feature.
Gusto tends to fit better if: you're already committed to QuickBooks, Xero, or a POS system that has a first-party Gusto integration, you're paying mostly or entirely contractors, you expect to grow past 10–15 employees within the next year or two (so the Plus-tier features become genuinely useful rather than dead weight), or you specifically want the HR resource center and compliance alerts that come with Premium.
The mistake to avoid either direction: signing up for a tier "to be safe" and paying for capacity you won't use for a year, or picking the cheapest plan and then discovering the multi-state or PTO feature you need is walled off behind an upgrade. Before committing, list your actual current requirements — not your five-year plan — and price each platform against that list specifically, not against its marketing page.
Bookkeeping From Day One, Not as an Afterthought
Whichever payroll tool you choose, the harder problem is usually what happens after the payroll run: getting wages, employer tax liabilities, and benefits deductions recorded correctly in your books so your P&L and cash position stay accurate. Payroll software calculates the numbers; it doesn't replace a clear ledger of what each pay run actually cost your business.
