Choosing a Payroll Outsourcing Provider: 9 Companies Compared by Features, Pricing, and Limitations

This year, payroll outsourcing companies are shaping how fast you scale, how safely you expand, and how confidently you pay people across borders. The company you choose impacts compliance exposure, cost control, and employee experience.

In this post, we break down the leading options, compare their strengths, and explain who each one is best for. We reviewed them to help you find and choose a provider that fits how your business operates today.

Comparison Table: Payroll Outsourcing Companies

Below is a comparison of the payroll outsourcing companies we’ve chosen based on delivery models, positioning, services, and pricing model fit.

How Did We Evaluate Each Outsourcing Company?

Choosing a payroll outsourcing company is about understanding how each one works under pressure. We evaluated each company using criteria that matter when you want to own risk and performance.

1. Payroll Capabilities

Many payroll outsourcing companies advertise automation and ease of use. That sounds good until you test edge cases.

What we considered:

• Multi-state payroll coverage
• Multi-country payroll execution
• Federal, state, and local tax filing automation
• Contractor and full-time employee support
• Off-cycle and bonus payroll flexibility
• Reporting depth and audit readiness
• Multi-currency payment processing

2. Global Coverage and Compliance Depth

International payroll introduces exposure that domestic systems never face. Global reach isn’t just about how many flags appear on a website map.

What we considered:

• Number of supported countries
• Employer of Record availability
• Local employment law expertise
• Statutory benefits handling
• Tax withholding accuracy across jurisdictions
• Data privacy compliance across regions
• Permanent establishment risk support

3. Workforce Infrastructure Beyond Payroll

Some payroll outsourcing companies process payments and stop there. If payroll is connected to hiring growth, this distinction becomes critical.

What we considered:

• Talent sourcing capability
• Onboarding support
• Benefits administration
• HR compliance advisory
• Replacement or backfill support
• Ongoing HR administration

4. Ideal Company Size and Use Case

Every outsourcing company markets itself as scalable. Few truly are. A startup’s needs differ dramatically from a multi-entity enterprise.

What we considered:

• Minimum employee requirements
• Scalability across business units
• Support model responsiveness
• Customization depth
• Integration flexibility
• Cross-border expansion readiness

5. Pricing Model and Commercial Structure

Payroll outsourcing companies often promote low per-employee pricing. That number rarely reflects the full financial impact.

What we considered:

• Base per-employee fee
• Set-up or implementation fees
• Year-end filing charges
• Multi-state or multi-country surcharges
• Add-on module pricing
• Contract duration requirements
• Early termination penalties

Payroll Outsourcing Companies Reviewed

Keep reading below for our full reviews of each company we picked for their payroll capabilities.

1. 1840 & Company

Best For: US-based companies hiring full-time international talent that need payroll, compliance, and workforce infrastructure under one provider.

At 1840 & Company, we combine talent sourcing, vetting, onboarding, global payroll administration, and compliance management into one integrated workforce model. Unlike standalone payroll software providers, we embed payroll and Employer of Record (EOR) services into full-time international hiring, giving companies a compliant employment infrastructure rather than just a processing platform. Our model emphasizes long-term retention, cost efficiency compared to domestic hiring, and structured risk reduction.

Company Rating: 4.8 out of 5 (Clutch Verified)

Why We Stand Out:

• Reduces vendor sprawl and eliminates the need to coordinate separate recruiters, EOR providers, and payroll platforms.
• Clients directly manage the individual, while we handle employment infrastructure, payroll, and compliance.
• There are no upfront sourcing fees, and billing begins only when talent starts. If a hire does not work out, we offer a replacement guarantee.

Why We Might Not Be A Match:

• We only support full-time dedicated placements. Companies seeking project-based or shared-resource models may need a different provider.
• BPO engagements require at least three dedicated resources, which may not suit very small teams.
• Organizations looking solely for domestic payroll software without staffing or global employment support may find simpler SaaS payroll platforms more aligned with their needs.

Pricing Model: Based on role, country, and employment structure. Global payroll and EOR services are bundled into the employment cost rather than sold as standalone SaaS tiers.

2. Remote People

Best For: Companies expanding internationally that need payroll combined with hiring and compliance infrastructure.

Remote People is a global payroll and workforce platform built for companies operating across multiple countries without internal HR infrastructure.

It goes beyond payroll software by combining global payroll with Employer of Record (EOR), recruitment, and contractor management, making it a more complete solution for international hiring.

Company Rating: 4.7 out of 5 (G2)

What Stands Out:

• Global payroll across 150+ countries, handling payments, taxes, and compliance without requiring local entities.
• Integrated hiring infrastructure, including EOR, recruitment, contractor management, and expansion support.
• Human-led support model, giving access to payroll and compliance specialists alongside the platform.
• Built for scale, supporting both growing companies and complex international operations.

What Falls Short:

• Limited integrations, which may be restrictive for companies with complex HR or finance tech stacks.

Pricing Model:

• Flat, transparent pricing, starting at around $50 per employee per month depending on country and scope.
• Modular services, with EOR, recruitment, and other services priced separately.

This structure allows companies to scale services without committing to bundled contracts.

3. ADP

Best For: Mid-market and enterprise organizations that need a mature payroll infrastructure with strong compliance coverage across multiple jurisdictions.

ADP is one of the largest payroll providers in the world, built for organizations that require formal controls, layered approvals, and audit-ready reporting. While it delivers payroll processing, it primarily operates as a provider of payroll and human capital management software.

Company Rating: 4.2 out of 5 (Gartner Verified)

What Stands Out:

• Supports businesses ranging from small companies to multinational enterprises through product tiers such as RUN Powered by ADP and ADP Workforce Now.
• It supports consolidated reporting across jurisdictions, which is valuable for companies operating in multiple regions that require centralized financial oversight.
• ADP provides controls designed to meet enterprise governance standards and support finance teams during audits or regulatory reviews.

What Falls Short:

• Pricing is not fully transparent and often requires custom quotes. Costs can increase significantly as additional modules and services are added.
• Larger ADP products may require structured onboarding, data migration, and configuration processes that can extend timelines.
• It does not provide recruitment, staffing, or employment infrastructure services for companies seeking global hiring support.

Pricing Model: Pricing is typically quote-based and is influenced by headcount, selected modules, and service complexity. Implementation fees may apply depending on configuration.

4. Gusto

Best For: Small to mid-sized US businesses that want user-friendly payroll with integrated benefits and HR tools.

Gusto is a cloud-based payroll and HR platform. Its appeal lies in its simplicity, automation, and a clean user experience that reduces the administrative burden for lean teams. While strong domestically, Gusto is designed primarily for US-based teams.

Company Rating: 4.6 out of 5 (G2 Verified)

What Stands Out:

• Automatically calculates, files, and pays payroll taxes in all 50 states, including year-end forms such as W-2s and 1099s.
• Employers can manage payroll deductions and benefits enrollment in a single system rather than coordinating with multiple vendors.
• Unlimited payroll runs are included, which benefits companies with off-cycle payments or frequent payroll adjustments.

What Falls Short:

• Companies hiring employees in multiple countries typically require separate international payroll providers.
• Features such as performance management tools and deeper HR support are only available in premium subscription tiers.
• Multi-entity organizations or companies requiring layered approval workflows may find the platform less reliable than enterprise-focused HCM systems.

Pricing Model: Offers transparent subscription tiers with a base monthly fee plus a per-employee charge. Higher plans unlock expanded HR tools and support. No long-term contract is required for most plans.

5. Paycor

Best For: Mid-sized US companies seeking payroll integrated within a broader human capital management platform.

Paycor is a mid-market HCM provider rather than a simple payroll processor. Its strength lies in delivering operational visibility through dashboards and reporting tools. That said, it is primarily optimized for domestic payroll environments.

Company Rating: 3.9 out of 5 (G2 Verified)

What Stands Out:

• Embeds payroll into a wider human capital management system that includes recruiting, onboarding, time tracking, and workforce analytics.
• Users can generate labor cost reports, turnover insights, and compliance summaries from a centralized interface.
• Structures its offerings by business scale, offering different solution bundles for growing companies and more established mid-market organizations.

What Falls Short:

• Paycor’s core strength is domestic payroll. Companies requiring robust multi-country payroll capabilities may need additional providers.
• Pricing is not publicly listed and typically requires bundling multiple modules, which can increase overall cost as more functionality is added.
• Compared to entry-level payroll platforms, implementation may require structured onboarding, configuration, and system integration, particularly for larger organizations.

Pricing Model: Paycor pricing is custom-quoted based on company size and selected HCM modules. Payroll is typically bundled with additional HR tools.

6. OnPay

Best For: Small US businesses that want straightforward payroll with transparent pricing and full-service tax filing included.

OnPay is a cloud-based payroll provider that’s appealing to small business owners who want predictable pricing without negotiating contracts or adding multiple paid modules. Payroll processing, tax filings, and year-end forms are bundled into its standard offering.

Company Rating: 4.8 out of 5 (G2 Verified)

What Stands Out:

• There are no tiered feature gates for standard payroll processing, which makes cost forecasting easier for small businesses.
• Federal, state, and local payroll tax calculations, filings, and payments are handled within the base plan.
• Allows businesses to process payroll for both traditional employees and independent contractors in the same system.

What Falls Short:

• OnPay is designed primarily for domestic payroll and does not offer built-in multi-country payroll infrastructure.
• The platform focuses on payroll and core HR functions rather than broader workforce analytics or enterprise-level reporting.
• Organizations managing multiple legal entities or layered approval workflows may find their customization options more limited than those of larger HCM providers.

Pricing Model: Uses a flat pricing structure with a monthly base fee plus a per-employee charge. Most core payroll features, including tax filings and year-end forms, are included in the standard rate.

7. Square Payroll

Best For: Retailers and restaurants already using Square POS who want payroll tightly connected to time tracking and tip reporting.

Square Payroll is built as an extension of the broader Square ecosystem. They emphasize simplicity and speed over enterprise depth. While highly efficient for service-based small businesses, it is not structured for organizations managing international payroll.

Company Rating: 4.2 out of 5 (G2 Verified)

What Stands Out:

• Square Payroll syncs directly with Square POS and Square Shifts, automatically flowing hours worked and tip data into payroll.
• Calculates, files, and pays federal and state payroll taxes on behalf of employers. Digital W-2 and 1099 forms are generated and distributed through the platform.
• Square offers a lower-cost payroll plan specifically for businesses that pay independent contractors, making it flexible for companies that don’t run full-time employee payroll.

What Falls Short:

• Square Payroll is built primarily for domestic payroll and does not provide native multi-country payroll processing.
• They focus on payroll execution and do not offer deep workforce analytics or enterprise-grade HR modules.
• Organizations managing multiple entities or layered approval workflows may find customization options limited compared to larger HCM providers.

Pricing Model: Charges a monthly base fee plus a per-employee rate for full-service payroll. A lower-cost contractor-only option is available.

8. JustWorks

Best For: Startups and growing US businesses that want bundled payroll, benefits, and HR support through a PEO model.

Justworks is an all-in-one HR platform built around the PEO model. Their model works well for companies that want to offload administrative complexity, though it is primarily optimized for US-based operations rather than large-scale international workforce management.

Company Rating: 4.6 out of 5 (G2 Verified)

What Stands Out:

• Operates as a Professional Employer Organization, enabling small and mid-sized businesses to access large-group health insurance and benefits plans.
• Payroll processing, tax filings, benefits administration, and compliance assistance are delivered through a single, structured platform.
• Justworks publicly lists its pricing tiers based on headcount and service level. This allows companies to estimate costs without entering a lengthy sales process.

What Falls Short:

• Under the PEO model, employees are technically co-employed by Justworks. Some prefer to retain full employer-of-record control without shared employment arrangements.
• Optimized for domestic payroll and benefits administration rather than large-scale international workforce management.
• Larger organizations requiring advanced workflow controls or multi-entity governance structures may find the platform less flexible than enterprise-focused HCM systems.

Pricing Model: Costs vary depending on plan level and benefits access. Pricing increases with headcount and selected service tier.

9. SurePayroll

Best For: Very small businesses and sole proprietors that need basic payroll with minimal setup complexity.

SurePayroll is a simple online payroll solution and focuses on core payroll functions. While suitable for small domestic teams, it is not ideal for organizations managing complex compliance environments or international payroll requirements.

Company Rating: 4.4 out of 5 (G2 Verified)

What Stands Out:

• Calculates, files, and remits federal and state payroll taxes on behalf of employers. It also prepares and distributes year-end forms such as W-2s and 1099s.
• Allows employers to run payroll on mobile devices, which is useful for owners who are frequently off-site or who manage operations hands-on.
• SurePayroll is owned by Paychex, providing access to established payroll systems and customer support resources backed by a large national provider.

What Falls Short:

• SurePayroll is designed for domestic payroll and does not offer native multi-country payroll services.
• The platform focuses primarily on payroll execution and does not provide deep workforce analytics or enterprise-level HR modules.
• Certain services and support features may vary by pricing tier, affecting overall cost and functionality.

Pricing Model: SurePayroll uses a monthly base fee plus per-employee pricing. Plan features vary, and certain services may depend on the selected package level.

How Should You Choose a Payroll Outsourcing Company?

Payroll touches compliance exposure, employee trust, financial accuracy, and expansion velocity. The right choice depends on how your business operates today and where it is headed.

Step 1: Define Your Geographic Reality

Before comparing providers, clarify your footprint. If your organization is US-only, many SMB platforms will work. If you are expanding into Latin America, Europe, or Asia, your options narrow quickly.

Ask yourself:

1. Are we operating in one state or multiple states?
2. Are we planning to hire internationally?
3. Do we need support in high-regulation markets?

Step 2: Understand Your Workforce Structure

Payroll complexity increases with workforce diversity. Misclassification penalties can be severe. Payroll outsourcing should reduce that exposure, not amplify it.

Evaluate your structure:

Step 3: Decide Between Payroll Processor, PEO, or Global Partner

Not all payroll outsourcing companies operate the same way. Understanding this distinction prevents costly mismatches.

Payroll Software Provider:

• You remain the employer.
• The platform processes payroll.
• Compliance responsibility stays largely internal.

PEO Model:

• Co-employment structure
• Benefits bundled
• Shared compliance responsibility

Global Workforce Provider:

• Supports international hiring
• May offer Employer of Record coverage
• Combines payroll with employment infrastructure

Step 4: Evaluate Cost Structure Beyond the Headline Price

A low per-employee fee can hide long-term exposure. The most affordable platform upfront may carry hidden rigidity.

Cost Factors to Examine:

• Implementation fees
• Add-on module charges
• Year-end filing costs
• Multi-state surcharges
• Early termination penalties

Cost Checklist:

1. Is pricing predictable month over month?
2. Are cost increases clearly defined?
3. Is there contractual lock-in?
4. Who absorbs penalty risk if errors occur?

Step 5: Pressure-Test Scalability

Growth changes payroll needs quickly. Scalability is not just about adding employees. It is about maintaining operational clarity while complexity increases.

Consider:

1. Will this system support acquisitions?
2. Can it handle entity expansion?
3. Does it integrate with accounting systems?
4. Is reporting robust enough for board-level oversight?

Quick Decision Framework

Choosing the right payroll outsourcing company reduces risk. Choosing the wrong one creates friction that compounds over time. If you are:

• A small domestic team → SMB payroll software may be sufficient
• A mid-market company → HCM-focused payroll platforms may align
• Expanding globally → Consider providers with international payroll infrastructure
• Building offshore teams → Look for payroll combined with employment support

Final Thoughts

Payroll outsourcing companies are not interchangeable. Some are built for simple domestic payroll. Others support layered compliance across multiple jurisdictions. The right choice depends on your growth plans, risk tolerance, and workforce footprint. If you are hiring internationally or building full-time global teams, payroll is only part of the equation. You need a compliant infrastructure behind it.
