Payroll is the first financial process a startup cannot afford to get wrong. A late invoice annoys a vendor. A late or incorrect paycheck breaks trust with the people building your company, and a missed payroll tax filing generates penalties that compound quietly until a state notice lands eighteen months later.
The good news is that the payroll software market is mature. For a US startup in 2026, there are five or six credible providers, they all calculate withholding correctly, and the differences that matter are about fit: your headcount, how many states you are in, whether you pay international contractors, and how much HR infrastructure you want bundled with the paycheck engine.
This guide compares the providers venture-backed startups actually use: Gusto, Rippling, ADP, Justworks, Deel, and OnPay. Pricing reflects published rates as of mid-2026; several providers quote custom pricing, and we flag where that is the case.
How to Evaluate a Payroll Provider
Five criteria separate the providers in practice.
Multi-state tax filing. Every remote hire in a new state creates registration, withholding, and unemployment insurance obligations in that state. All the major providers technically cover all 50 states, but they differ in how much of the registration burden they take on and at which pricing tier multi-state filing is included. If you have remote employees in five states, this is the criterion that will consume the most of your time when it goes wrong.
Contractor and EOR support. Most startups pay a mix of W-2 employees and 1099 contractors, and an increasing share hire abroad. Paying a US contractor is table stakes. Paying an international contractor compliantly, or employing someone in another country full time through an employer of record (EOR), is where providers diverge sharply.
Benefits administration. Health insurance, 401(k), workers compensation. The question is not whether a provider offers benefits but how good the underlying broker relationships are at your headcount. A 10-person startup and a 200-person company get quoted very different plans, and some providers are much stronger at one end than the other.
Equity and HRIS integration. Payroll is where option exercises, bonuses, and taxable fringe benefits get reported. If you grant equity, you want a provider that plays reasonably well with your cap table platform and produces reports your accountant can work with at year-end. If you want onboarding, PTO, and device management in the same system, that is an HRIS decision as much as a payroll one.
Price per employee. The honest unit of comparison. Base fees, per-employee fees, per-contractor fees, and setup fees vary enough that two providers can differ by 2x at the same headcount. PEO models charge on a different basis entirely, which we cover under Justworks.
Gusto: The Default for Startups Under 50
Gusto is where most venture-backed startups start, and for good reason. The product is genuinely easy to run without an HR hire, pricing is transparent, and contractors are included in every plan.
Pricing. Three tiers as of 2026: Simple at $49 per month plus $6 per person, Plus at $80 per month plus $12 per person, and Premium at $180 per month plus $22 per person. No setup fee. Note the fine print that matters for startups: multi-state payroll requires the Plus tier, as does time tracking. International contractor payments are also gated to Plus and above.
Strengths. Founder-friendly UX, transparent pricing, contractors included across plans, full 50-state coverage, benefits brokerage that works well for small teams, and clean reporting with solid API access, which your accountant will appreciate at month-end and year-end.
Trade-offs. The benefits brokerage gets thinner as you pass 50 employees, HR features are adequate rather than deep, and there is no IT or device management. Most companies that outgrow Gusto do so between 100 and 250 employees, usually because they want a real HRIS rather than because payroll itself breaks.
Who it fits. Startups from first hire through roughly Series B, especially teams that value simplicity and want their accountant working in a system with good data access.
Rippling: Payroll Plus HR Plus IT, at a Price
Rippling sells a unified platform where payroll is one module among many: HR, benefits, IT and device management, app provisioning, and global payroll all live in one system with shared employee records.
Pricing. Modular and quote-based. The core platform starts around $8 per employee per month, and each module adds its own per-employee charge. In practice, companies running payroll alone commonly land in the $25 to $50 per employee per month range all-in, and stacking HR, payroll, and IT together can run $60 or more per employee per month. Implementation fees are common. Two similar companies can pay meaningfully different rates depending on modules and negotiation.
Strengths. The deepest HRIS workflows in this comparison, real IT and device management (a genuine differentiator when every new hire needs a laptop provisioned), strong automation across modules, and credible global payroll and EOR options.
Trade-offs. Steeper learning curve, and the modular pricing means costs creep as you adopt more of the platform. A common mistake is buying the full suite before you need it: if all you need today is payroll and benefits, you may be paying for leverage you will not use for a year.
Who it fits. Scaling companies, typically 30 employees and up, that want payroll, HR, and IT unified and are willing to invest in setup. A very common path is starting on Gusto and moving to Rippling as complexity grows; our Gusto vs Rippling comparison covers that decision in detail.
ADP: Enterprise Muscle, Small-Business Clunk
ADP is the incumbent, and its small-business product, RUN Powered by ADP, is aimed at companies with 1 to 49 employees, with Workforce Now above that.
Pricing. Quote-based. RUN's Essential plan starts around $79 per month plus $4 per employee, across four packages (Essential, Enhanced, Complete, HR Pro). Setup fees of $200 to $500 are common but negotiable, and the effective price depends heavily on your sales rep. Most small businesses report paying $100 to $300 per month once add-ons are included.
Strengths. Excellent 50-state coverage, the deepest benefits brokerage relationships in the market, dedicated support reps at higher tiers, and genuine enterprise scalability: ADP will still be your payroll provider at 5,000 employees if you want it to be.
Trade-offs. The interface is dated and built for HR professionals rather than founders, contractor payments carry separate fees, reporting is comprehensive but clunky to extract, and equity compensation reporting typically requires manual workpapers. Many startups end up on ADP because a rep signed them up at incorporation, and most under 100 employees are overpaying 20 to 40 percent versus Gusto for equivalent scope. We wrote a full ADP vs Gusto comparison on exactly this switch.
Who it fits. Startups in regulated industries that need white-glove compliance support, companies scaling past 250 employees, or teams whose HR leadership already has deep ADP expertise.
Justworks: The PEO Option
Justworks is not payroll software in the same sense as the others. It is a professional employer organization: you enter a co-employment relationship, and Justworks becomes the employer of record for tax and benefits purposes while you direct the day-to-day work.
Pricing. Per-employee rather than base-plus-per-seat: PEO Basic at $79 per employee per month and PEO Plus, which adds medical insurance access, at $109 per employee per month as of 2026. Justworks also sells a standalone payroll product at around $50 per month plus $8 per employee for teams that want software without the PEO wrapper.
Strengths. The core PEO pitch is real: a 10-person startup gets access to large-group health insurance rates it could never negotiate alone, plus bundled workers compensation, 401(k), and compliance support. For small teams in expensive insurance markets, the benefits arbitrage can genuinely offset the fee.
Trade-offs. The math inverts at scale. At 50 employees, PEO Plus is roughly $65,000 per year before insurance premiums, far more than software-model providers, and the benefits advantage shrinks as your own group gets large enough to negotiate directly. Co-employment also adds friction when you leave: unwinding a PEO means re-registering for state tax accounts and rebuilding benefits mid-flight. Plan the exit at year-end.
Who it fits. Teams of roughly 5 to 30 that want great benefits immediately and are willing to pay for zero HR overhead, particularly in states where small-group health insurance is brutal.
Deel: International Hiring First
Deel approaches the market from the opposite direction: it began with international contractors and EOR, and added US payroll later.
Pricing. Contractor management at $49 per contractor per month. EOR, where Deel employs your international hire through its local entity, starts at $599 per employee per month at list, with negotiated rates commonly reaching $400 to $500 at 20-plus headcount. Global payroll for your own foreign entities runs around $29 per employee per month, and US payroll is quote-based. EOR arrangements typically also involve a refundable salary deposit, and cross-border payments carry a disclosed currency conversion markup.
Strengths. The broadest international coverage in this comparison, with local entities in 100-plus countries, strong contractor compliance documentation, and localized contracts. If your team is a US core plus engineers in four countries, Deel handles the part everyone else treats as an afterthought.
Trade-offs. For a purely domestic team, Deel's US payroll is not the natural first choice; its strength is abroad. EOR costs are significant per head and worth periodic review: once you have several employees in one country, forming a local entity and running payroll directly often becomes cheaper than perpetual EOR fees.
Who it fits. Startups with meaningful international hiring, whether contractors today or full-time employees abroad without local entities. Many of our clients pair a domestic provider like Gusto with Deel for the international side.
OnPay: The Value Pick
OnPay is the least known name on this list and worth including precisely because of what it does not do: no tiers, no upsells, one plan with everything included.
Pricing. A single all-inclusive plan at roughly $49 to $55 per month base plus $6 per person as of 2026, including multi-state payroll, W-2 and 1099 processing at no extra fee, unlimited pay runs, and basic HR tools.
Strengths. The best pure price-to-capability ratio in this comparison. Multi-state filing is included in the single plan rather than gated to a higher tier, and support quality is consistently well reviewed.
Trade-offs. No international contractor payments, a thinner integration ecosystem than Gusto or Rippling, more limited benefits brokerage reach, and nothing resembling an HRIS. It is a payroll engine, deliberately.
Who it fits. Cost-conscious domestic teams, including multi-state ones, that want accurate payroll and nothing else. Less common among venture-backed startups than Gusto, mostly because investors and accountants know Gusto better, not because OnPay is worse at running payroll.

Our Recommendation by Situation
Five-person startup, one or two states, no international hires. Gusto Simple. It is cheap, your accountant already knows it, and you will not think about payroll for more than twenty minutes a month. If you are watching every dollar, OnPay does the same core job for slightly less with multi-state included. Choose a provider the same week you make your first hire; retroactively fixing payroll registrations is far more expensive than setting them up correctly.
Multi-state remote team. Gusto Plus or Rippling. The provider files in every state, but you still need to register in each state where you have employees, and that registration burden is where remote-first startups get hurt. Whichever provider you choose, keep a live list of states, registration status, and filing frequency, and reconcile state filings quarterly. This is also the situation where a PEO deserves a look: Justworks absorbs much of the state-level administration if you would rather pay per employee than build the process.
International contractors or employees. Deel, usually alongside a domestic provider. Contractors in a few countries: Gusto Plus or Rippling can handle it. Full-time employees abroad without a local entity: you need an EOR, and Deel is the strongest dedicated option, with Rippling the right answer if you want EOR inside the same platform as your US payroll and HRIS.
Scaling past 50 with growing HR and IT needs. Rippling. The consolidation of payroll, HR, benefits, and device management into one system is worth the setup investment at this stage, and it removes an entire category of onboarding busywork.
Whatever you choose, switch at year-end. A mid-year migration forces two systems to issue partial W-2s, which confuses employees and adds accountant work. Migrations typically take 2 to 4 weeks; start planning in October.
Where StartupCFO Fits
We do not sell payroll software, and there is no software integration between our platform and any payroll provider. Here is what we actually do.
Payroll runs in your provider: our clients are on Gusto, Rippling, ADP, and Justworks. Our accountants reconcile every payroll run into your books each month, so wages, employer taxes, and benefits land in the right accounts and your payroll tax filings tie out to your general ledger. That reconciliation is part of our bookkeeping service, and it is where most self-managed startups quietly accumulate errors.
If you want us hands-on in the payroll system itself, running the payrolls, managing state registrations, onboarding new hires into the provider, payroll support is available as an add-on at $50 per W-2 employee per month on our plans.
For the mechanics of setting payroll up correctly in the first place, including the W-2 versus 1099 classification decisions that trip up early teams, our startup payroll setup guide walks through it step by step. And if you are weighing providers and want a second opinion grounded in your actual headcount and state footprint, book a free consultation and we will talk through the specifics.
