Frequently asked questions

Is Bullhorn a CRM or an ATS?

Actually, it’s both.

Bullhorn is widely known as an ATS (Applicant Tracking System), and it does that job really well. You can manage your candidate pipeline, schedule interviews, track placements, and keep everything organized in one place.

But it’s also a CRM (Customer Relationship Management) platform, built specifically for the staffing industry. That means you can also use it to manage client relationships, track communication, and build long-term partnerships with the companies you recruit for.

So whether you’re nurturing candidate relationships or growing your client base, Bullhorn has tools to support both sides of the desk.

What is Bullhorn used for?

Bullhorn is a software platform that combines applicant tracking (ATS) and customer relationship management (CRM) all in one.

It’s designed for staffing and recruiting teams to keep everything organized: candidate details, client communication, job openings, interview progress, you name it.

With Bullhorn, your team can:

Track every step of the hiring process
Store and access candidate profiles in one place
Keep client conversations and job orders flowing
Collaborate without losing context

In short, Bullhorn helps recruiters spend less time digging through spreadsheets or email threads and more time connecting the right people to the right roles.

How do Bullhorn marketplace apps work?

Bullhorn Marketplace apps are like plug and play upgrades for your ATS.

They’re pre-built integrations that connect popular third-party tools, like texting platforms, e-signature software or sourcing tools directly to Bullhorn. These apps use Bullhorn’s open API to create smooth, automated workflows between systems.

The best part?

Most of them are super easy to set up. Just a few clicks, and you’re good to go.

Once connected, these apps let your data flow automatically between platforms, so your team spends less time on manual tasks and more time making hires.

Are Bullhorn integrations free?

Not exactly.

Bullhorn itself usually doesn’t charge you to activate an integration - that part is typically free. But the third-party tools you’re integrating? Most of them come with their own subscription costs.

So, while the integration setup might not cost anything upfront, you'll still need to pay for the actual software you're connecting to Bullhorn - like CallMantra, Sense, or Dropbox Sign.

Some apps do offer free plans or limited features at no cost, which can be helpful if you're just testing things out. But for full functionality, expect to invest in a subscription.

That said, the ROI can be well worth it. The time you save, the increase in recruiter productivity, and the smoother workflows often pay for themselves pretty quickly, especially when you’re making more placements, faster.
