OnPay Review: Pricing, Features, Pros and Cons

OnPay does one thing exceptionally well: it gives small businesses a full payroll, HR, and benefits platform without the tiered pricing games that plague this category. For $49 per month plus $6 per employee, you get every feature OnPay offers. No upsells, no locked capabilities, no surprise fees at year-end. In a market where competitors like Gusto and ADP gate critical features behind premium tiers, that simplicity is genuinely refreshing.

We found OnPay to be one of the strongest payroll solutions for businesses with 1 to 150 employees. The tax accuracy guarantee, multi-state payroll at no extra charge, and licensed benefits administration across all 50 states make it a particularly compelling choice for small businesses that have outgrown basic payroll tools but don’t need (or want to pay for) an enterprise HRIS. The trade-off? A relatively small integration ecosystem, no built-in time tracking, and a mobile experience that lags behind larger competitors.

What Is OnPay?

OnPay is a cloud-based payroll, HR, and benefits platform built for small businesses. The company has roots in a family payroll business with over 30 years of history. Jesse Burgess joined the family operation in 2007, and OnPay officially launched as a standalone software subsidiary around 2015. The company is headquartered at Ponce City Market in Atlanta, Georgia, and has secured over $100 million in funding, including a $63 million Series B round led by Carrick Capital Partners.

OnPay now serves more than 20,000 businesses across the United States. It has collected numerous industry recognitions, including PCMag’s Editors’ Choice award and Forbes’ Best Overall All-in-One Payroll and HR for Small Businesses designation. The platform handles payroll processing, tax filings, employee onboarding, PTO management, benefits administration, and basic HR functions, all bundled into a single subscription with no feature tiers.

OnPay Key Features

Unlimited Payroll Processing

OnPay allows unlimited pay runs per month at no additional cost. You can pay W-2 employees and 1099 contractors, run off-cycle payrolls for bonuses or corrections, and support multiple pay schedules (weekly, biweekly, semi-monthly, monthly) without incurring extra charges. Payment methods include direct deposit, paper checks, and pay cards. Many competing platforms either charge per payroll run or limit the number of runs on their base plans.

Automated Tax Filing with Error-Free Guarantee

OnPay handles all federal, state, and local payroll tax calculations, filings, and payments. This includes quarterly tax filings, year-end W-2 and 1099 processing, and state new hire reporting. The standout here is OnPay’s tax accuracy guarantee: if OnPay makes an error on your tax filings, they pay the resulting IRS penalties and fines. Multi-state payroll is included at no extra charge, which is a meaningful differentiator since some competitors charge additional fees for employees in multiple states.

Employee Self-Onboarding

New hires can complete their own onboarding through automated workflows. This includes filling out I-9 and W-4 forms online, e-signing documents, and entering direct deposit information. The system handles state new hire reporting automatically. The onboarding process is consistently cited as one of OnPay’s strongest features, with the platform providing a structured flow that reduces manual HR work for small teams that may not have a dedicated HR person.

Benefits Administration

OnPay operates as a licensed insurance broker in all 50 states through OnPay Insurance Agency, LLC. This means the company can directly quote and administer health insurance, workers’ compensation, and disability insurance without relying on third-party brokers. You only pay the plan premiums; there are no integration or administration fees from OnPay. For retirement benefits, OnPay partners with Guideline and Vestwell for 401(k) plans, and also supports FSAs. This in-house benefits capability is unusual for a platform at this price point.

HR Tools and Document Management

The HR suite includes PTO policy creation and tracking, a document vault for contracts and employee records, personnel files, searchable org charts, direct messaging, compliance audits, and an HR resource library powered by Mineral (formerly ThinkHR). OnPay also offers custom forms for additional employee information, making employee profiles more thorough than what many competitors offer at this tier. All of these HR features are included in the base subscription, not locked behind a higher plan.

Employee Self-Service Portal

Employees get their own portal to view and download pay stubs, access tax documents (W-2s, 1099s), update personal information, manage direct deposit details, and view PTO balances. A mobile-friendly web interface and mobile app allow employees to access these features on the go. The self-service portal reduces the administrative burden on business owners by letting employees handle routine information requests themselves.

Reporting and Accountant Tools

OnPay includes a report designer for building custom payroll reports, along with standard reports for payroll summaries, tax liabilities, and labor costs. The platform offers a dedicated accountant dashboard with six levels of user permissions, making it straightforward for bookkeepers and CPAs to manage multiple clients. The accountant partner program includes revenue-sharing incentives for firms managing 50 or more clients.

Industry-Specific Features

OnPay includes specialized payroll support for industries that have unique tax requirements. This covers agriculture (Form 943 support), nonprofits, churches and religious organizations (clergy FICA exemption handling), restaurants, law firms, manufacturing, retail, construction, and healthcare. These niche capabilities are baked into the standard plan, making OnPay a strong fit for small businesses in these verticals that would otherwise need specialized payroll services.

OnPay Pricing and Plans

OnPay’s pricing model is one of the simplest in the payroll software market. There is a single plan with all features included.

For a business with 10 employees, the monthly cost comes to $109 ($49 base + $60 for employees). For 25 employees, it’s $199 per month. Some older third-party sources still list OnPay’s legacy pricing of $40/month base; the current price confirmed on OnPay’s website is $49/month base.

The single-plan structure is a genuine advantage. Competitors like Gusto lock PTO management, time tracking, and other features behind plans that cost $80 to $100+ per month in base fees plus $12+ per employee. ADP and Paychex use custom, quote-based pricing that often includes per-payroll-run fees and module add-ons. OnPay’s all-inclusive approach means you won’t discover missing features after signing up and face pressure to upgrade.

Benefits premiums for health insurance, workers’ compensation, disability insurance, and 401(k) plan fees are separate costs paid to the insurance or retirement providers. OnPay does not charge additional fees for administering these benefits.

Integrations

OnPay’s integration ecosystem is functional but limited compared to larger platforms. The confirmed integrations include:

• Accounting: QuickBooks Online, QuickBooks Desktop, Xero
• Time tracking: QuickBooks Time (formerly TSheets), Deputy, When I Work
• Retirement/401(k): Guideline, Vestwell
• HR compliance: Mineral (formerly ThinkHR)
• Workplace compliance: PosterElite

The QuickBooks Online integration is the most popular and highest-rated connection, syncing payroll data directly to your general ledger. OnPay also mentions support for various applicant tracking and tax credit tools on its website, though specific partners for those categories are not detailed.

The integration list is notably shorter than what you’ll find with platforms like Rippling (600+ integrations) or Gusto. There is no confirmed public API for custom integrations, and Zapier/Make support is not documented. If your business relies on a specific HR tool, project management platform, or industry application, verify compatibility with OnPay before committing. The platform supports both English and Spanish languages.

Customer Support

OnPay offers phone, email, and in-app chat support from 9 AM to 8 PM Eastern Time, Monday through Friday. The support team is US-based, which is worth noting since some competitors outsource support or restrict phone access to higher-priced tiers.

Every new customer gets a dedicated onboarding specialist who walks through initial setup, data migration from previous payroll providers, and first payroll processing. Several sources confirm that OnPay proactively reaches out by phone during onboarding, and some customers report being offered Zoom sessions to assist with their first payroll run. The 30-day free trial period doesn’t start its countdown until your account is fully set up, which is a thoughtful touch.

Self-service resources include a searchable Help Center knowledge base and a YouTube channel with instructional videos. The seven-step self-onboarding process is available for those who prefer to set up independently.

Customer support quality is consistently one of OnPay’s highest-rated attributes. The onboarding experience, in particular, stands out as above average for this price category. That said, some reports of delayed issue resolution and occasional slow response times during peak periods (such as tax season or year-end) are worth keeping in mind. OnPay actively responds to negative feedback on public review platforms, which suggests an engaged support culture.

Pros and Cons

OnPay delivers strong value for small businesses, but it’s not without limitations. Here’s our assessment of where the platform excels and where it falls short.

Who Should Use OnPay?

OnPay is best suited for US-based small businesses with 1 to 150 employees that need payroll, basic HR, and benefits administration in a single, affordable platform. It’s an especially strong fit for businesses that operate in multiple states, since multi-state payroll is included at no extra cost.

The industry-specific features make OnPay particularly appealing for restaurants, farms, nonprofits, churches, and other organizations with unique payroll tax requirements. These businesses often struggle to find affordable payroll software that handles their specialized needs without expensive add-ons or manual workarounds.

Accounting firms and bookkeepers managing payroll for multiple small business clients should look at the accountant partner program, which provides a centralized dashboard and volume-based discounts.

OnPay is not the right choice for businesses that need built-in time tracking and scheduling (you’ll need a separate tool or a platform like Gusto or Rippling). It’s also not ideal for fast-growing companies that anticipate needing a full HRIS with performance management, learning management, or deep applicant tracking. International businesses with employees outside the US will need to look elsewhere, as OnPay is US-only. And if your tech stack relies on dozens of integrations, OnPay’s limited ecosystem may be a constraint.

OnPay Alternatives

Gusto

Gusto is OnPay’s closest competitor and is often recommended for payroll newcomers thanks to its polished interface and guided setup. However, Gusto’s base plan ($49/month + $6/person) lacks features that OnPay includes at no extra cost, such as PTO management and next-day direct deposit. To get comparable functionality, you’d need Gusto’s Plus plan ($80/month + $12/person), which is significantly more expensive. Choose Gusto if you value a more modern UX and built-in time tracking; choose OnPay if you want all features at one price.

ADP Run

ADP Run is a better fit for fast-growing businesses that anticipate scaling beyond 100 employees and need to eventually transition to a mid-market platform like ADP Workforce Now. ADP offers a much larger integration ecosystem and broader HR capabilities at higher tiers. However, ADP’s pricing is opaque (quote-based), typically more expensive, and some plans charge per payroll run. If you’re a stable small business that values cost predictability, OnPay is the better deal.

Square Payroll

Square Payroll starts at a lower base fee ($35/month + $6/employee) and integrates natively with the Square POS ecosystem, making it a natural choice for retail and food service businesses already using Square for payments. However, Square charges extra for benefits administration and retirement plan integration, and its HR features are minimal compared to OnPay’s included suite. If you’re a Square merchant, Square Payroll may be more convenient; otherwise, OnPay offers more value.

Rippling

Rippling is the choice for businesses that want a modular, highly integrated platform covering payroll, HR, IT, and device management. With 600+ integrations and an app marketplace, Rippling is far more extensible than OnPay. But that power comes with complexity and higher costs. Rippling’s modular pricing means you pay for each component separately, and it targets companies with more sophisticated needs. For straightforward payroll and HR, OnPay is simpler and cheaper.

Paychex Flex

Paychex Flex offers a broad range of payroll and HR services with dedicated account managers, and it scales well from small businesses to mid-market companies. Like ADP, pricing is custom and generally higher than OnPay’s. Paychex is a stronger option for businesses that want hands-off payroll management with a more traditional service model, but OnPay wins on transparency, self-service capability, and cost for businesses comfortable managing payroll through software.

Frequently Asked Questions

How much does OnPay cost per month?

OnPay charges a $49/month base fee plus $6 per active employee or contractor per month. All features are included in this single plan. There are no setup fees, no contracts, and no extra charges for multi-state payroll, W-2/1099 filings, or HR tools. A 30-day free trial with full feature access is available without a credit card.

Does OnPay handle multi-state payroll?

Yes. OnPay processes payroll and files taxes in all 50 US states at no additional charge. This includes state tax registrations, quarterly filings, and year-end reporting. Some competitors charge extra fees for multi-state payroll, making OnPay a cost-effective choice for businesses with employees in multiple states.

Does OnPay have a mobile app?

OnPay offers a mobile app for employees to access pay stubs, tax documents, and personal information. The platform is also accessible through mobile-responsive web browsers. However, there is no dedicated employer-side mobile app for running payroll or managing HR tasks on the go, which is a gap compared to competitors like ADP and Gusto.

Does OnPay include time tracking?

No. OnPay does not include built-in time tracking or scheduling tools. You’ll need to use a separate time-tracking solution and connect it through one of OnPay’s integrations (QuickBooks Time, Deputy, or When I Work). This is one of the most commonly noted limitations of the platform.

What happens if OnPay makes a tax filing error?

OnPay offers an error-free tax accuracy guarantee. If OnPay makes a mistake on your payroll tax calculations or filings, the company will pay any resulting IRS penalties and fines. This guarantee covers federal, state, and local tax filings handled through the platform.

Can OnPay administer health insurance and retirement benefits?

Yes. OnPay operates as a licensed insurance broker in all 50 states and can quote and administer health insurance, workers’ compensation, and disability insurance directly. For retirement benefits, OnPay partners with Guideline and Vestwell for 401(k) plans, and also supports FSAs. You pay the insurance and retirement plan premiums separately; OnPay does not charge additional fees for benefits administration.

How do I cancel OnPay?

OnPay operates on a month-to-month basis with no long-term contracts. You can cancel at any time by calling OnPay’s support team at 877-328-6505. There are no cancellation fees or early termination penalties.

The Bottom Line

OnPay earns its reputation as one of the best payroll solutions for small businesses, and our review confirms why. The single-plan pricing structure eliminates the frustrating tier comparisons that waste hours during the buying process. For $49 plus $6 per person, you get payroll, HR tools, and benefits administration that competitors charge two to three times as much for when you add up all the required upgrades.

The platform’s strengths are clear: transparent pricing, a tax accuracy guarantee that puts real money behind the promise, multi-state payroll at no extra cost, in-house benefits brokerage across all 50 states, and customer support that consistently earns high marks. The weaknesses are equally clear: a limited integration ecosystem, no built-in time tracking, a mobile experience that needs improvement, and an HR feature set that, while solid, won’t satisfy businesses needing performance management or advanced workforce analytics.

If you’re a US-based small business with fewer than 150 employees, especially in a specialized industry like agriculture, nonprofits, or restaurants, OnPay should be on your shortlist. It delivers more value per dollar than nearly any competitor in its class. If you need extensive integrations, global payroll, or a full-featured HRIS, look at Rippling, Gusto Plus, or ADP instead. For everyone else, OnPay is the rare payroll platform that actually delivers on the promise of simplicity.
