OnPay vs Gusto: Full-Feature Payroll at Lower Cost vs a Broader HR Platform in 2026

OnPay vs Gusto — the small business payroll comparison where price and feature breadth trade off directly

The typical buyer for this comparison is a company under 50 employees evaluating their first or second payroll system. Often migrating from manual payroll, QuickBooks payroll, or a local accountant-managed solution. The trigger: needing multi-state filing, contractor management, or direct deposit setup without a dedicated payroll person. Both OnPay and Gusto are fully self-service and do not require a payroll specialist to operate. Both platforms are designed for HR generalists and founders who want to run accurate payroll without becoming payroll experts. The evaluation question is not whether either platform works — both do — but which delivers the features the business actually needs at the price point that fits the budget.

The structural difference that makes this comparison interesting is OnPay's single-plan model against Gusto's three-tier architecture. OnPay prices at $40/month base plus $6/employee — and that price includes everything the platform offers. Gusto also starts at $40/month base plus $6/employee (Simple tier) — but Gusto Simple is payroll only. The HR, onboarding, and benefits features the Gusto brand is known for are Plus-tier ($80/month base plus $12/employee) and above. Gusto Premium runs $180/month base plus $22/employee. Evaluating 'OnPay vs Gusto' without naming which Gusto tier is being compared is comparing apples to different price points — and most buyer confusion in this comparison comes from that omission.

Feature comparison — where OnPay's pricing simplicity and Gusto's feature breadth separate

Both OnPay and Gusto cover the full-service payroll baseline for US small businesses. Automated payroll runs, multi-state tax filing and deposits, direct deposit, W-2 and 1099 generation, new hire reporting across all 50 states. The divergence is in benefits administration, onboarding tooling, HR features, and how much the buyer pays to access them. OnPay collapses all of those into a single plan. Gusto distributes them across three tiers, each at a materially higher price. The right comparison is to match the feature set the business actually needs to the tier on each platform that delivers it — and then compare the cost of those equivalent configurations.

Core payroll processing and compliance

OnPay and Gusto both handle automated payroll runs, multi-state tax filing and deposits, direct deposit, W-2/1099 generation, and new hire reporting. Processing quality is equivalent for standard US small business payroll. Neither is the right call for complex payroll scenarios — union payroll, certified payroll for government contracts, or large multi-state compliance programs with local jurisdiction complexity. OnPay's payroll accuracy and compliance reliability are well-documented: the platform has processed payroll since 2011 and carries a strong track record in third-party reviews with error-free tax filing guarantees backed by a penalty-and-interest policy. For standard payroll — salaried employees, hourly workers, direct deposit, multi-state filings — this feature category is effectively a tie between the two platforms.

Pricing model — OnPay's single plan vs Gusto's three tiers

This is the central comparison. OnPay: $40/month base plus $6 per employee. All features included: payroll, HR tools, benefits integration via third-party broker, onboarding, time-off tracking, multi-state, 1099 contractors, org chart, document storage. No upsells. Gusto Simple: $40/month base plus $6 per employee. Payroll only — tax filings, direct deposit, W-2/1099 generation, and new hire reporting. HR tools, onboarding workflows, benefits administration, PTO automation, and time tracking require Gusto Plus at $80/month plus $12 per employee. Gusto Premium: $180/month plus $22 per employee adds dedicated support and compliance alerts. At the Simple tier, OnPay and Gusto are the same price — and OnPay includes the features Gusto Simple withholds. The cost comparison only favors Gusto when the full Plus feature set (especially integrated benefits without a broker) is a hard requirement and the premium is accepted. The table below makes the cost difference concrete across common headcount ranges.

OnPay matches Gusto Simple at every headcount — and includes the features Gusto Simple withholds. The comparison that favors Gusto is OnPay versus Gusto Plus: Gusto Plus adds integrated benefits administration without a broker and onboarding workflow automation. At 25 employees, that's $190/month additional annually to choose Gusto Plus over OnPay. Whether that $2,280/year premium is worth the integrated benefits and onboarding tools depends on whether those specific features are a hard requirement for the buyer.

Benefits administration — the feature that most often decides this comparison

This is where the comparison genuinely turns. Gusto Plus includes benefits administration with direct carrier relationships in most US states — the company can offer health, dental, vision, and 401(k) through Gusto without maintaining a separate broker relationship. Gusto negotiates rates and manages enrollment natively. Employees enroll directly through the Gusto platform; HR doesn't coordinate between a payroll system and an external broker portal. OnPay integrates with benefits but does not replace the broker relationship — employers work with their own broker to configure benefit plans, set up deductions in OnPay, and sync them with payroll. For companies that want benefits and payroll in one system without a broker: Gusto Plus. For companies with an existing broker relationship, or companies that don't yet offer group health coverage and aren't ready to select one, OnPay's integration is sufficient and the price difference is not justified.

HR tools and onboarding workflows

Gusto Plus includes employee onboarding workflows — customizable task lists, document collection, offer letters, and an HR resource center. New hires receive a self-service onboarding portal where they complete paperwork before their first day: direct deposit setup, W-4 withholding, benefits enrollment, and signed documents. The workflow is automated from the employer side, reducing the per-hire administrative time meaningfully. OnPay includes basic HR tools — org chart, document storage, PTO tracking and policy management — but does not have Gusto's onboarding workflow automation. For a company hiring two to five people per month, Gusto's onboarding workflows reduce the time-per-new-hire in a way that compounds over the year. For a company hiring fewer than one person per month on average, the onboarding workflow automation rarely justifies the Plus premium on its own.

Contractor payroll

Both OnPay and Gusto handle 1099 contractor payroll and year-end 1099-NEC filing. OnPay includes contractor payroll in the standard plan with no separate contractor-specific configuration or fees — businesses with a mix of W-2 employees and 1099 contractors manage both in the same interface from day one. Gusto includes contractor payroll on all paid plans and also offers a contractor-only plan at $35/month plus $6 per contractor for companies with no W-2 employees — a useful option for early-stage businesses paying contractors before bringing on full-time employees. For businesses with a mix of employees and contractors, both platforms handle this natively. OnPay's single-plan model means there is no question about whether contractor support is included — it always is.

Integrations and accounting sync

Both OnPay and Gusto integrate natively with QuickBooks Online, Xero, FreshBooks, and major accounting platforms — payroll journal entries sync automatically after each run, eliminating manual reconciliation between payroll and accounting. Gusto has a broader third-party integration library overall, including time tracking tools (Homebase, TSheets), HRIS platforms, and a wider benefits partner network. OnPay's integration set is narrower but covers the accounting, time tracking, and benefits platforms that most small businesses under 50 employees actually use in practice. For accounting-forward small businesses that live in QuickBooks or Xero, both platforms perform equivalently on the integration that matters most.

Shortlist snapshot — when each platform is the right call

Keep OnPay when…

Budget is the primary constraint and full-feature payroll is needed without tier-based upsells. An existing broker relationship handles benefits — OnPay's integration syncs payroll deductions without replacing the broker, so there is no need to change the benefits setup. Onboarding workflow automation — offer letters, customizable task lists, self-service new hire paperwork portals — is not a buying requirement. Headcount is under 50 and expected to stay there over the next two to three years — OnPay's simplicity scales comfortably within this range. Pricing predictability over a multi-year horizon matters: OnPay's single-plan structure is straightforward to model with no tier upgrade risk as the team grows.

Keep Gusto when…

Integrated benefits administration without a separate broker relationship is required — Gusto's direct carrier relationships in most states eliminate the need for an outside broker for health, dental, vision, and 401(k) enrollment. Onboarding workflow automation — customized task lists, offer letter generation, self-service new hire portals — is a buying criterion that saves meaningful time per hire. Modern brand recognition matters for recruiting and employee experience positioning; Gusto's self-service portal is consistently cited positively in employee reviews. Company expects to grow past 50 employees and wants a platform with a clear upgrade path (Simple → Plus → Premium) within the same vendor without a platform migration.

Drop OnPay if…

Integrated benefits administration — direct carrier relationships without a separate broker — is a hard requirement. Onboarding workflow tools — customized task lists, offer letter automation, self-service new hire portals — are on the buying criteria list. These are the two features OnPay does not match Gusto Plus on. Everything else OnPay covers equivalently at lower cost: payroll processing, multi-state compliance, time-off tracking, contractor payroll, accounting integrations, and basic HR tools all deliver comparable outcomes at OnPay's single-plan price.

Drop Gusto Simple if…

You need any of the features that Gusto places behind the Plus tier: HR tools, PTO automation, onboarding workflows, time tracking, or benefits integration. If these are requirements, compare OnPay against Gusto Plus specifically — not Gusto Simple — and model whether the $6/employee/month premium over OnPay is justified by those specific features. Gusto Simple at $40 plus $6/employee is payroll only; treating it as a full-feature comparison to OnPay misstates the actual decision.

OnPay — what the platform actually does well and where it stops

OnPay's core value proposition is pricing honesty: every feature the platform offers is included in the base plan, and the per-employee cost is fixed regardless of which features the business uses. There are no module upgrades, no add-on fees for HR tools, and no tier unlocks for multi-state payroll — all of it is standard. For small business operators who have been burned by platforms that advertise a low starting price and progressively add costs as features are unlocked, OnPay's single-plan model is a meaningful differentiator. The platform has operated since 2011, maintains an error-free tax filing guarantee backed by a penalty-and-interest reimbursement policy, and has strong ratings for accuracy and support responsiveness in third-party review platforms.

OnPay's payroll interface is functional and well-organized, though not as polished or brand-forward as Gusto's. The trade-off is intentional — OnPay is built for operational reliability rather than consumer-grade design. For the typical small business operator who runs payroll twice a month and wants it done accurately and quickly, the interface is sufficient. For companies where the employee-facing experience — the self-service app, the pay stub portal, the onboarding portal — is part of the employer brand or talent strategy, Gusto's more modern design language has an advantage.

The honest limitation of OnPay is its onboarding workflow tooling and benefits integration model. OnPay does not automate multi-step onboarding workflows — there is no equivalent to Gusto's customizable task lists, automated offer letter generation, or self-service new hire portal that collects paperwork before the first day. Benefits deductions sync with payroll, but the benefits administration itself happens with a separate broker — OnPay does not provide carrier-direct enrollment or negotiate rates on the employer's behalf. For companies with a broker and under 50 employees that hire infrequently, these gaps are manageable. For companies actively recruiting and onboarding multiple new hires per month with a benefits program, these are real functional shortfalls.

Gusto — where the platform earns its premium and where the tiering creates friction

Gusto's strongest case is made by the Plus tier, not the Simple tier. Gusto Simple is a capable payroll processor, but the features that built Gusto's reputation — integrated benefits, onboarding workflows, HR tools, PTO automation — are entirely absent from Simple. Buyers who evaluate Gusto based on marketing materials and then purchase Simple are often surprised by how much is missing. The buying decision for Gusto is really a decision about Gusto Plus: is the $80/month base plus $12/employee — approximately double OnPay's cost — worth the integrated benefits administration without a broker and the onboarding workflow automation? For buyers where those two features are requirements, the answer is often yes. For buyers where they are nice-to-haves, the math rarely works out.

Gusto's integrated benefits administration is genuinely differentiated. In most US states, Gusto has established direct relationships with major health insurance carriers — United, Aetna, Kaiser, Blue Cross Blue Shield networks — and can quote, enroll, and manage health, dental, and vision plans through the platform without requiring a separate insurance broker. For small businesses that have not yet selected a benefits broker, Gusto Plus eliminates that procurement step entirely and centralizes the enrollment experience in the same interface employees use for payroll. That consolidation has real value for the 10–35 employee company that is building out its benefits program for the first time.

Gusto's onboarding workflow is also a genuine capability advantage over OnPay. The system allows HR teams to configure customized onboarding checklists, generate offer letters from templates, collect e-signatures on required documents, and give new hires access to a self-service portal where they complete their setup before the first day. At 2–5 new hires per month, the per-hire time savings compound. The honest limitation: Gusto's tiering means buyers must commit to the Plus price to access these features — and the Plus price at 25 employees ($380/month) is double what OnPay charges for most of the same functionality. The premium is real and buyers should model it before signing.
