There's no license you need to open a background check company. None. Anybody with a website and a database subscription can call themselves a screening provider, and plenty do. Nobody warns you about that until you've already signed a contract with one that turns out to be a mess.
I'm not here to rank the top ten providers for you. Rankings go stale the minute a company changes its pricing. What I'll give you is the same six-part framework I used for almost 30 years, plus a simple way to score your shortlist. Run it against two or three vendors and the real differences show up fast. A few of these six points get their own deep dive later. This one gets you through the whole decision in one sitting.
Most people don't choose a background check company. They inherit one. Somebody's old boss used a certain vendor, so that's who gets the call. Or three quotes come in and the cheapest wins, because a spreadsheet doesn't show you what a company's like six months in.
Then the surprises show up. A fee that wasn't on the quote. A turnaround promise that only applies to the easy cases. Nobody to call when your vendor gets audited and you need to prove you did your homework. A real evaluation gives you what a gut feeling never will: a paper trail. "My old boss used them" doesn't hold up to Legal or Finance. A scored comparison does. Nobody's checking these companies' work for you. That job falls on you.
Six things actually matter here. Everything else is noise.
Turnaround and compliance are the two I'd call non-negotiable. Get those wrong and you'll feel it. Pricing and support are more flexible, they depend on your size and how much hand-holding you need. No single criterion should sink a vendor by itself, except a real compliance red flag. This is a weighing exercise, not a pass-or-fail test.
The Professional Background Screening Association runs a program called the Background Screening Agency Accreditation Program, BSAAP for short. It's a real, independent audit of a company's data security, legal compliance, and how it actually runs its business. Not just a logo it slaps on the homepage.
Only a small slice of background check companies nationwide hold this accreditation. I won't print an exact percentage, that number moves and I'd rather send you to check it than hand you a stale figure. Holding it means something. Not holding it doesn't automatically mean a company's bad, plenty of solid smaller shops never bothered with the process. It just means you ask more questions.
Ask for the certificate and the number, then check it's current, because accreditation runs on a cycle and it definately can lapse. And know the difference between "PBSA accredited," which means audited, and "PBSA member," which just means they paid dues. Not the same thing.
Every provider quotes you a "starting at" price. That's a hook, not a total. The real cost usually hides in three places: county court fees that swing wildly by courthouse, monthly platform fees charged no matter your volume, and one-time ATS setup fees nobody mentioned on the sales call.
Ask for a full, itemized fee schedule and a real sample invoice, not a mockup built for the pitch deck. If a quote lands noticeably below everyone else's, don't celebrate. Ask why. Cheap pricing comes from somewhere, usually data quality or compliance work getting cut.
A vendor will tell you turnaround is "24 to 48 hours." That's almost always the fast piece, a database search, not the full package you're actually running. Ask for turnaround broken out by check type. Criminal, employment verification, education, driving record, each one moves at its own speed, and lumping them into one number hides where the real delays live.
The slow part is almost never the vendor typing slower. It's a courthouse that only processes requests once a week, or a past employer that takes ten days to return a call. Ask what the provider does when a search stalls. Do they escalate, or just shrug?
If you run people through Workday, Greenhouse, Lever, iCIMS, BambooHR, ADP, or UKG, ask whether the provider has a real, native connection to it. Not a spreadsheet you upload by hand every Friday and call an "integration."
Ask specifically about adverse action. Can the pre-adverse and final notices trigger from inside your ATS, or does that step happen off to the side where it's easy to forget? That's the part most likely to bite you if it slips through a crack. Ask how deep the integration goes, too. A real two-way connection beats a one-way data push that leaves your team re-entering everything by hand.
Every legitimate provider should support a standalone FCRA disclosure and a signed authorization before any check goes out. That's the floor, not a differentiator. If a vendor's fuzzy on this, walk away.
Where providers actually separate is the adverse action process, the two-step notice you're required to send before turning someone down over a report. Does the provider hand you a pre-adverse packet, with the report and a summary of rights, and track the waiting period before the final notice? Or are you running that whole thing by hand?
Ask how they handle state and local rules stacked on federal law too, things like state-specific consent language or ban-the-box timing. I'll be straight with you. The specifics change by state, and they change over time. I'm not a lawyer, and I wouldn't trust a blog post as anybody's legal source here, mine included. Check anything that matters with your own attorney.
This is the one people skip, then regret. Ask whether you get a named account contact or land in a shared ticket queue. That matters most when you're first getting set up, and when something goes wrong.
Get a real number for first response time, not "we're responsive." Ask how disputes and re-checks get handled, and by who. Ask what onboarding looks like, is there a sandbox to test in, and what's a realistic go-live timeline. Can't answer that last one straight? That tells you something too.
Here's the version I actually used. Put the six criteria down the side, your two or three finalist vendors across the top, then score each box 1 to 3. Or, for more nuance, tag each criterion Essential, Important, or Flexible based on what matters for your hiring. Clinical or regulated roles? Weight Compliance Support and Accreditation heavier. High-volume hourly hiring? Weight Turnaround Time heavier, because a slow check costs you a candidate who took another offer while you waited.
The score isn't the final answer. It's how you narrow ten vendors down to two or three worth an actual phone call, a reference check, or a small pilot batch before you sign anything.
Any one of these alone might be nothing. Three or four together, and that's a company telling you exactly who they are. Believe them.
Copy these straight into your next demo call or RFP.
This piece is the wide-angle view. For the deep dives, look for articles on verifying an accreditation claim, a full pricing and hidden-fee breakdown, a turnaround comparison, an ATS checklist by platform, and an FCRA and adverse action walk-through built for employers, not lawyers.
Applying this whole framework to an actual list of vendors is exactly what a matching tool is for. Running the numbers by hand works fine too. I did it for 30 years. But I won't pretend it's the fast way.
