Payrolling Through Your Staffing Vendor? You Might Be Overpaying

By:  Ariana Lujan

Payrolling and staffing are often bundled together, but they serve very different purposes. When those differences blur, companies can end up paying far more than necessary for employer of record (EOR) services that could be delivered more efficiently and transparently.

Understanding how these models differ, and where costs quietly compound, can help leaders make more informed decisions about their workforce strategy, including when to use an EOR for payrolling.

Summary

This article explains the difference between payrolling (where an EOR handles payroll, compliance, and benefits) and staffing (where agencies recruit and employ workers). It shows how using a staffing vendor for payroll can raise costs, especially with agency markups that are often 35% to 50%, and less transparency and control. The article also covers the benefits of direct payrolling or in-house solutions, such as lower costs, more control, and custom integrations. It gives steps to review your current expenses, compare providers, and plan a smooth transition. The aim is to help businesses find a more cost-effective and compliant payroll option.

Payrolling vs. Staffing: What’s the Difference?

Payrolling refers to an arrangement where an Employer of Record (EOR) manages payroll administration, tax withholding, benefits, and employment compliance for workers you already source or select. The focus is on operational accuracy, compliance, and risk management. A good payrolling service makes sure benefits are managed properly, and the company follows all local, state, and federal rules. Staying compliant is important because not doing so can lead to serious penalties and legal trouble.

Staffing, by contrast, includes recruiting, screening, and employing workers on your behalf. Staffing agencies assume responsibility for sourcing talent and typically charge a markup to cover recruitment, management, and overhead. Staffing usually starts with figuring out what the company needs, then finding and screening candidates to match those needs. Staffing agencies have access to many job seekers, which can speed up hiring.

Both models have valid use cases. Problems arise when staffing vendors deliver employer of record services using a structure designed primarily for talent acquisition. If you choose to use a staffing vendor for payrolling, you might be paying extra without realizing it. These extra costs can affect your profits, so it’s important to understand them to make smart financial choices.

Where Costs Start to Add Up

When companies bundle payrolling through a staffing vendor, they often pay staffing-style markups for services that do not require staffing-level effort.
Typical staffing markups can range from 35% to 50% or more of worker pay. While that premium may make sense when sourcing, screening, and managing talent, companies often pay more than the true cost of payrolling services alone.
In many cases, businesses effectively pay recruitment margins for payrolling execution.

Limited Visibility, Limited Control

Another challenge with payrolling through staffing vendors is compliance and transparency, especially compared with direct EOR or employer of record payrolling models. This lack of transparency can lead to unexpected expenses, making it difficult to budget accurately. Businesses may find themselves paying for services that are not essential or receiving less value than anticipated for the fees charged.

Vendors frequently bundle costs into a single bill rate, making it difficult to see how much goes toward wages, statutory costs, benefits, and vendor margin. Without clear line-of-sight into these components, leaders struggle to:
  • Accurately forecast payroll spend
  • Identify inefficiencies or unnecessary fees
  • Compare alternatives on an apples-to-apples basis

This lack of visibility also limits flexibility. Adjusting processes, changing benefit structures, or scaling across geographies can require renegotiating staffing contracts that staffing vendors did not design for payroll-first needs.

Why Direct Payrolling Models Are Different

Dedicated payrolling or EOR solutions purposefully handle employment, payroll, and compliance without embedding staffing markups.

Key advantages typically include:

  • Lower overall cost by eliminating recruitment-based margins
  • Clear pricing models tied to payroll services, not bill rates
  • Greater transparency into wages, taxes, benefits, and fees
  • More control over compliance workflows and worker data
  • Scalability across states or countries without restructuring vendor relationships

Organizations that already have access to talent, or that use multiple sourcing channels, often achieve enhanced governance and more predictable costs by separating staffing from payrolling.

How to Evaluate Your Current Payrolling Spend

If your organization currently manages payrolling through a staffing vendor, you can take a few practical steps to clarify whether you are overpaying:

  1. Review your bill rates – Break down what portion of the rate is wage versus markup, and understand what services that markup is intended to cover.
  2. Assess transparency – Determine whether you can clearly see payroll costs, statutory expenses, and administrative fees.
  3. Compare alternatives – Benchmark against dedicated payrolling or EOR providers that price payroll independently of staffing.
  4. Plan for transition – Any change should include a clear timeline, employee communication, and coordination to avoid payroll disruption.

A More Intentional Payroll Strategy

Payrolling through a staffing vendor can feel convenient, especially early on. But as programs scale, that convenience often comes with hidden cost and reduced control.

Separating payrolling from staffing allows organizations to pay for what they actually need, gain better visibility into spend, and build a more flexible workforce foundation.

The right model depends on your workforce mix, growth plans, and compliance requirements. What matters most is understanding where your payroll dollars are going and ensuring they align with the value being delivered.
