Costs, Providers & How It Works (2026 Guide)

Payroll outsourcing is the practice of hiring a third-party provider to calculate wages, withhold taxes, file payroll tax forms, and pay employees on your behalf. Small businesses often outsource payroll because tax compliance rules, multi-state regulations, and wage calculations can quickly become complex and time-consuming.

Payroll outsourcing can be an easy way to save time and money. Rather than tracking and calculating employee payroll by hand or using spreadsheets, you can hire a professional employer organization (PEO), a national or local bookkeeper, or an accountant who will handle payroll for you.

Many small business owners outsource their payroll and HR functions because of how complicated and time-consuming these can be. Payroll outsourcing services will gather your employees’ information (hire date, job title, and pay rate) and time card data, calculate the amount due to each employee, calculate taxes, and then pay that amount by issuing a direct deposit or payroll check.

Features of outsourced payroll

Payroll outsource service providers have the pay processing expertise needed to accurately pay employees. Most payroll outsourcing companies provide:

• Payroll account setup and payment configuration
• New hire reporting to state agencies
• Automated wage, overtime, and deduction calculations
• Wage garnishment processing and remittance
• Quarterly and annual tax filings (Form 941, Form 940, W-2, 1099)
• Basic employee recordkeeping
• Secure payroll data storage
• Payroll compliance monitoring and updates

How payroll outsourcing services work

Payroll outsourcing providers manage the full payroll cycle, from collecting employee data to filing payroll taxes and issuing payments. While workflows vary slightly by provider and company size, most services follow a structured process like this:

1. 1. Payroll system setup: The provider sets up payroll software with your company and employee data, including your payroll bank account and employees’ bank accounts for direct deposit.
   2. New hire reporting: They collect new employee information and provide state-required new hire reporting.
   3. Time and attendance collection: The provider requests or obtains time card data (clock-in and clock-out times or hours worked) each pay period to input into payroll software.
   4. Gross pay calculation: They confirm hours worked each pay period as paid or unpaid and calculate gross pay.
   5. Deduction processing: The system applies pre-tax deductions (like benefits and taxes) and post-tax deductions (like garnishments for child support).
   6. Payroll processing and employee payments: The provider runs payroll and makes deposits to employees’ accounts (direct deposit, pay card) and mails or delivers paychecks to your office or employees’ homes.
   7. Tax filing and remittance: Payroll taxes are calculated and remitted to the appropriate agencies.
   8. Vendor and benefits payments: If applicable, they also make payments to vendors, such as insurance companies, on your behalf.
   9. Reporting and documentation: The business receives payroll reports, tax filing confirmations, and year-end forms such as W-2s and 1099s.

When outsourcing payroll makes sense

Outsourcing payroll makes the most sense when your business lacks the time, expertise, or internal capacity to manage payroll accurately and compliantly.

In many small businesses, one person typically performs both bookkeeping and payroll functions. If you don’t have a dedicated accountant or bookkeeper on staff and hiring one full-time isn’t financially practical, outsourcing can provide professional oversight without the cost of a full-time salary.

According to Glassdoor data published in 2025, the average salary range for a payroll specialist in the United States falls between $54,000 and $82,000 per year, excluding benefits and employer payroll taxes. For many small businesses, outsourcing payroll or using payroll software can cost significantly less than hiring a full-time payroll professional.

Payroll outsourcing options

Payroll outsourcing ranges from hiring a local bookkeeper to partnering with a full-service national payroll provider. Costs typically start at under $100 per month for basic processing and can reach several thousand dollars per year for comprehensive payroll and HR support.

What differentiates providers isn’t just price, but also level of service. Some handle only payroll calculations and tax filings, while others manage benefits administration, compliance monitoring, and HR functions. The right option depends on how much responsibility you want to retain versus delegate.

Professional employer organization (PEO)

A professional employer organization (PEO) is a co-employment partner that manages payroll, HR, and benefits while you retain control of day-to-day business operations.

A professional employer organization (PEO) is a co-employer, meaning you and the PEO split employment duties. You’ll manage your company’s day-to-day business while the PEO handles HR, payroll, and benefits processing.

A PEO is the best option for:

• Companies that need personalized HR support. If your employees have a question about their latest paycheck, they can call and speak to a dedicated team member who knows your business.
• Businesses with complex payroll or deduction needs. If your company receives a notice to garnish an employee’s paycheck, the PEO will work on filing the garnishment under its own employer identification number (EIN).
• Businesses that want to offer competitive benefits. A PEO hires your employees and then leases them back to you. It adds your employees to a pool with its other clients’ employees to drive down benefit costs so it can offer affordable premiums.
• Businesses without in-house HR. PEOs provide HR, payroll, benefits, and, often, HR consulting services. It saves you from having to hire a full-time HR, benefits, and payroll person.

Below are a few of the popular PEO options that can be a great fit for small businesses:

National bookkeeping service

A national bookkeeping service provides remote accounting and payroll support for small businesses, often bundling both services into one platform.

These firms typically operate online and serve clients across multiple states, offering centralized financial management and payroll processing.

A national bookkeeping service is the best option for:

• Business operations in multiple states. A local provider may only have the expertise for the local area, but a national firm should have resources for every state. You will have access to the same services you would receive from a local firm with some extras, like year-end financials.
• Tech-enabled or remote-first companies. National bookkeepers are usually remote, and, therefore, most of your communication is done via the internet or over the phone, including documents you or your bookkeeper need to send to each other.
• Companies that want accounting and payroll in one place. Consolidating services can simplify reporting, tax preparation, and year-end financials.
• Companies that need additional payroll services. Bookkeepers can help process garnishments or run an off-cycle payroll for year-end bonuses.

If you’re looking for online bookkeeping services, below are our top-recommended providers:

Local bookkeeper or accountant

A local bookkeeper or accountant provides in-person payroll and accounting support, often tailored to businesses operating within a specific state or community. This option can combine payroll processing with hands-on financial guidance, especially if you already work with a trusted local professional.

If you already have someone managing your bookkeeping, you might want to ask them if they can run your payroll too. For example, if they’re a QuickBooks ProAdvisor, they may be able to process your payroll using QuickBooks Payroll.

If you want to try the services of a ProAdvisor-certified accountant, check out our guide to finding a QuickBooks ProAdvisor.

A local bookkeeper is best for:

• Business owners who value in-person support. You can interact face-to-face with the team working on your payroll and HR without hiring a full-time person in-house.
• Small businesses on a budget. Local bookkeepers can cost much less than hiring a full-time employee to manage your small business payroll, which is what can make it a great option for many small business owners.
• Small mom-and-pop businesses. Apart from being affordable, a local bookkeeper could provide the payroll and accounting integration that these businesses need.
• Businesses operating in one state. Local professionals often have deep familiarity with state and municipal tax requirements.

Alternative to payroll outsourcing services

If full payroll outsourcing isn’t the right fit, payroll software offers a lower-cost way to automate payroll while keeping control in-house.

Payroll software allows business owners to process payroll, calculate taxes, and file required forms using a self-managed platform. Unlike outsourcing, you remain responsible for final review and compliance, but much of the calculation and filing work is automated.

This option is often more affordable than hiring a PEO or external provider, especially for small businesses with straightforward payroll needs.

When choosing the right payroll service for your business, you’ll want to consider what your payroll budget is and what kind of add-ons are valuable to you.

Payroll software might be the best option for your small business if:

• You have employees who will manage payroll and HR in-house.
• You need some automation, from payroll processing to filing payroll taxes, but still want to review and approve from within.
• You want self-service options so employees can manage their own payroll needs.

Below are a few of the payroll software that can be a great fit for small businesses:
