Why BOSS

One Platform. Four Operating Models.

BOSS is a software-first Employer of Record for staffing agencies that combines payroll, compliance, funding, technology, and back-office operations into one integrated platform.

Unlike traditional payroll companies or standalone Employer of Record providers, BOSS gives staffing firms the flexibility to choose how they operate while keeping every placement, employee, client, and payroll on one connected system.
Whether you remain the employer, use BOSS as your Employer of Record, fund payroll yourself, or have BOSS fund payroll for you, the platform stays exactly the same. Only the operating model changes.
Everything is built specifically for staffing firms. Payroll processing, employee onboarding, tax administration, workers’ compensation, compliance, invoicing, reporting, payroll funding, AI automation, and open REST API integrations all work together through one secure platform.
That means fewer vendors, less administrative work, better visibility into your business, and more time for your recruiters to focus on what matters most: making placements and growing revenue.

The four BOSS operating models on one platform: Core Plan where you employ and fund, Funded Plan where BOSS funds payroll, Self-Funded EOR where BOSS employs, and Complete Plan where BOSS employs and funds, each including the full BOSS platform.

EOR Testimonials

Staffing leaders who switched to BOSS, in their own words.

Moving from People 2.0★★★★★

I HIGHLY recommend BOSS as an EOR, especially after working with them for the last few years after previously being with People 2.0. Their new client setup, employee onboarding and portal, extremely responsible and knowledgeable account management/customer service, and never ever an issue with our folks or ourselves getting paid. They are also truly a one-time set-up portal, and every week payroll processes automatically, no interaction is needed on our end, and is seamless on all fronts. Our folks get paid on Friday and then we would get paid for that past week on Tuesday, they provided all the funding to us ahead of time at a FRACTION of the cost as well. We’ve worked with other Employer of Records and BOSS is number 1. As a staffing industry executive of almost 20yrs, I wouldn’t recommend anyone else!

Mark N., FounderMark N.Founder
Healthcare staffing moved from ESSG★★★★★

We love our BOSS team. We launched an agency before the pandemic and were with another EOR. The Employer of Record we were with did not give us the support we needed, and we were growing extremely fast. So, we decided to make the transition to BOSS after they launched, and we made the right choice. The support has only gotten better since the beginning and the brand-new App technology is superb, giving us the opportunity to utilize it to grow from anywhere. We are blessed to partner together while we continue to grow. Hands down the best EOR service with top-notch technology.

Danial P., CEODanial P.CEO
Using BOSS for out-of-state★★★★★

Back Office Staffing Solutions, our go-to EOR, has been invaluable in helping us expand our service offerings. By leveraging BOSS’ services, we can quickly enter new geographic markets or expand our staffing service lines. BOSS’ deep industry knowledge, flexibility, and unwavering commitment to customer service have consistently exceeded our expectations. They worked closely with us to customize a solution that would integrate best with our organization.

Jamie S., CEOJamie S.CEO
Franchise support, amazing speed & support★★★★★

BOSS gives us what we need the most, our time, by allowing us to focus on what we do best, sales and recruitment. Coming from the staffing industry themselves, they not only understand how urgent contract staffing can be but also how attention to detail, coupled with excellent customer service, can mean the difference between retaining or losing a sales opportunity. BOSS is ALWAYS super responsive and attentive to the velocity of our deals on the front end, as well as providing excellent follow-up and professionalism on the back end of invoicing, by managing collections and distributions for us. We couldn’t achieve our growth goals as quickly without BOSS. They are one of our most trusted partnerships and the best EOR we have seen.

What is an EOR

What Is an Employer of Record?

An Employer of Record (EOR) is a company that becomes the legal employer of the workers you place, so you don’t have to be.

Every contractor a staffing agency places has to be legally employed by someone: someone whose EIN is on the paycheck, who files the payroll taxes, who carries the workers’ compensation policy, and who answers for compliance in every state where workers sit. With BOSS as your EOR, that someone is us.

BOSS takes on W-2 employment, payroll processing and funding, tax filings, workers’ comp, and 50-state compliance. You keep your clients, your candidates, your rates, your brand, and 100% of your margin.

Diagram of what an Employer of Record does for a staffing firm: you keep your clients, candidates, bill rates, margin, and brand, while BOSS carries W-2 employment, payroll and funding, tax filings in all 50 states, workers' comp, I-9, and compliance.

FAQ

Employer of Record FAQs for Staffing Agencies

What does an Employer of Record (EOR) do for a staffing agency?

An Employer of Record acts as the legal entity that manages payroll funding, tax filings, workers’ compensation, and compliance. Staffing agencies use an Employer of Record to reduce liability and speed placements across multiple states and time zones. See our complete Employer of Record guide for details.

Does an Employer of Record handle background checks and onboarding?

Yes. An Employer of Record supports background checks, I-9 verification, e-Verify, and onboarding paperwork so candidates are compliant from day one. This gives staffing agencies a faster, cleaner start with fewer errors. Review our onboarding & verification requirements.

How does payroll funding work with an Employer of Record?

The Employer of Record advances payroll funding so workers get paid on time, even before client invoices are collected.

Can an Employer of Record provide health insurance and employee benefits?

Many Employer of Record services provide access to health insurance, retirement plans, and other employee benefits.
