Smarter Staffing Growth with Bullhorn + Zeal

If you’re in the staffing world, you’ve heard of Bullhorn. It’s the industry’s go-to ATS, helping companies source talent, manage pipelines, and place candidates faster than ever. 

But here’s the thing: creating an excellent candidate experience and improving your recruiting operations only helps you grow if you also create an excellent worker experience and improve your staffing operations.

For staffing companies who want to grow, pairing Bullhorn with Zeal is the fastest path to attracting the best workers while also building sustainable staffing operations.

If you’re a staffing leader looking to improve operations, this guide will show you why Zeal paired with Bullhorn is the most powerful way to run your business. 

The Challenge After Placement

An ATS like Bullhorn gets you to the offer letter. But once a candidate says “yes,” a new set of challenges begins — and this is where many staffing companies stumble.

Delayed Onboarding: Workers get lost in paperwork or sit idle for days while admins chase signatures and I-9s. For high-volume roles, this delay means candidates simply move on to another company with faster start times.

Broken Payroll: Generic systems struggle with multiple pay rates, overtime rules, or per diems. Workers expect to be paid correctly and on time, but instead face missed checks or confusing pay stubs, leading to frustration and turnover.

Late or Error-Filled Invoices: When billing doesn’t match client contracts or invoices go out late, cash flow slows. A single mistake in a rate card or overtime calculation can erode client trust instantly.

Compliance Gaps: Wage laws, tax rules, and worker classifications shift constantly. Without purpose-built tools, companies rely on spreadsheets or manual workarounds — a recipe for costly audits and penalties.

These aren’t minor back-office issues. They’re the difference between being a staffing company that grows — or one that loses workers and clients to someone with faster, smoother operations. 

The Four Pillars of Scalable Staffing (Post-Placement)

There are two major areas staffing companies can focus on to scale smarter: the front office, where you win and place talent, and the middle-to-back office, where you deliver on that promise with smooth operations.

That means:

  1. Onboarding without friction — so workers can start assignments the moment they’re placed.
  2. Payroll that’s accurate and fast — so talent stays loyal, even in competitive labor markets.
  3. Billing that’s automated and reliable — so clients get invoices they trust, and you get paid on time.
  4. Compliance handled for you — so you focus on growth not mitigating risk.

Bullhorn gives staffing companies the best possible front office. Zeal ensures everything that follows — the work of onboarding, paying, billing, and operating compliantly — meets that same standard.

Two Wrong Paths Staffing Companies Often Take

The operational challenges that staffing companies face aren’t really their fault. While Bullhorn has created front office software, specifically for staffing companies, the same thing for middle and back office hasn’t existed.When staffing companies for solutions to improve their middle and back office operations, they have historically only had two options. Neither of which is a complete solution, built for staffing.

1. The “Generic Payroll Provider”

These systems are built for any business, not the unique complexity of staffing. On paper, they can cut checks and file taxes. In reality:

  • Manual corrections for state-compliant paystubs: States like CA, NJ, and IL require every client, rate, and set of hours to be listed. Generic payroll providers are incapable of handling this out-of-the-box, forcing staffing companies to custom build paystubs (and risk penalties if it’s generated incorrectly). 
  • Gaps in wage & hour compliance - Overtime, minimum wage, and sick leave must be calculated on a per work-location basis. Generic systems push this burden back onto admins.
  • Inefficient mult-location taxation - When workers clock in one state on a Monday and another on a Wednesday, admins have to update worker profiles by hand. Zeal dynamically taxes based on actual work location, including nexus and reciprocity rules.
  • Missed or delayed filings - If tax IDs come in late, many providers won’t backdate filings, leaving staffing companies exposed to penalties. Zeal handles backdated filings automatically.
  • Hidden fees and slow support - Amended filings, off-cycle runs, or compliance corrections often trigger surprise charges and weeks-long delays. Zeal includes these in-platform, with dedicated success managers, tax experts, and fast turnaround.
  • Messy onboarding processes - Legacy technology results in a lack of cohesion and automation and as a result, onboarding becomes a patchwork of documents, emails, and manual data entry.
  • Duplicate data entry - Generic payroll systems aren’t deeply integrated with Bullhorn, which means recruiters and admins end up re-keying worker information across systems — introducing errors and wasting hours every week.

For a small local business with one location and a handful of employees, a generic provider might work. For a staffing company juggling hundreds of workers across multiple clients, it’s a costly slowdown.

2. The “All-in-One Platform”

These vendors promise the world: ATS, onboarding, payroll, invoicing, compliance — all under one roof. But here’s the reality:

  • Mediocre front-office tools - ATS and CRM features lag behind Bullhorn, making it harder to win talent and clients in competitive markets.
  • Deprioritized middle and back office functionality - Onboarding, payroll, and billing are tacked on, no purpose-built for staffing. 
  • Rigid workflows - One-size-fits-all functionality forces your team to adapt to the software rather than the tools adapting to your business needs. 
  • Incomplete solutions that require patchwork - When an all-in-one lacks critical functionality (and can’t prioritize it because product teams are spread thin), staffing companies end up bolting on new tools anyway — defeating the purpose of an “all-in-one.”
  • Locked in contracts and slow innovation - To soften the sticker shock when buying new software, all-in-one vendors bundle discounts into mult-year contracts. That guaranteed revenue locks staffing companies in and allows the platform to rest on their heels rather than delivering meaningful updates. 
  • Weak worker experience - White-label mobile and web apps are rarely included, leaving workers stuck in vendor-branded portals instead of your agency’s brand.

Why Zeal is Built for Staffing’s Middle and Back Office

While most payroll and operations platforms force staffing companies into bad fits — either generic payroll providers that can’t handle staffing complexity, or all-in-ones that do everything but excel at nothing — Zeal takes a different approach. 

We’re purpose-built to handle the hardest part of staffing: what happens after the placement. And unlike all-in-ones, Zeal pairs seamlessly with Bullhorn so you get the industry’s leading ATS on the front end and a staffing-optimized middle/back office powering everything that comes after.

Here’s what that looks like in practice:

Frictionless, branded onboarding — Workers complete I-9s, tax forms, certifications, and state-specific docs digitally in minutes. With white-label apps, the whole experience looks and feels like your agency, not a vendor portal.

Reliable payroll that builds loyalty — Multi-rate pay, overtime, per diems, and 50-state compliance are automated. Workers get paid correctly and on time — even same-day — inside the same branded experience.

On-time, error-free billing — Invoices generate automatically from Bullhorn data, aligned to client contracts and rate cards. Clients receive accurate, timely invoices that reinforce your professionalism.

Compliance built in — From wage laws and garnishments to tax updates, Zeal’s compliance engine keeps you current automatically. No last-minute scramble, no manual tracking.

With Zeal, staffing companies finally get a middle and back office built for how staffing actually works — efficient, compliant, and brand-forward.
