An ATS helps you hire people. An HRIS helps you keep track of them after you do. ATS stands for applicant tracking system. HRIS stands for human resources information system. One is about applicants, and the other is about employees.
The short answer
An applicant tracking system takes a job from posting to offer. It keeps your applicants, résumés, messages and interview notes in one list, so nobody falls through the cracks.
An HRIS takes over when someone says yes. It keeps their forms, job details, time off, benefits and files, and it usually gives the employee a way to see their own information.
The line between them is blurry. Plenty of products do some of both, so read past the label.
HRIS vs ATS, side by side
| Topic | ATS | HRIS |
|---|---|---|
| Main job | Hire people | Keep track of the people you hired |
| Who is in it | Applicants | Employees |
| Starts | When a job opens | When someone is hired |
| Typical records | Résumés, interview notes, hiring steps | Job details, forms, files, time off, benefits |
| Who uses it most | Hiring managers and recruiters | Owners, office managers and employees |
| Question it answers | Who should we call next? | Who owes us a form, and who is out on Friday? |
When an ATS may be all you need
If hiring is your only headache, an ATS can be a good fit. That might look like this:
- You hire often, and applicants get lost in email and texts.
- Your payroll company's plan already covers your employee records and time off.
- You have only a few long-term employees and very little paperwork after the hire.
If you're still working out whether you even need that, read spreadsheet vs software first.
When you need an HRIS
Your pain has moved past hiring if you see these:
- You chase new hires for forms, and you're not sure what's still missing.
- Employee files are spread across folders, email and a filing cabinet.
- Time off is tracked in someone's head.
- Benefits enrollment is a stack of forms once a year.
- Employees come to you for things they could look up themselves.
The gap most small businesses fall into
Here is where two separate systems tend to hurt. The moment you hire someone, their name, address, job and start date already exist in your hiring tool. Then someone types them again into the HR system, and again for payroll.
The first days also fall between the cracks. The hiring tool considers its job done, the HR system hasn't started, and nobody is checking whether the new hire is settling in. Those are the days when people decide whether to stay.
One system or two?
Two good tools can work well if they connect. One system is simpler if it does what you need. Ask these questions either way:
- Does a hire's information carry over, or does someone retype it?
- What will both cost together? Check per-employee and per-user fees at your size.
- Who owns the first 90 days? Is anything keeping an eye on new hires?
- How many logins will your managers and employees need?
Where HRGP fits
HRGP is an HRIS with applicant tracking built in, for small businesses. Applicant tracking is one part of it, not the whole thing.
You track applicants, use interview guides and text people in the same place where you run onboarding and keep employee records. Then First 90 Days check-ins pick up where most hiring tools stop. Onboarding is for US businesses.
See HRGP as an HRIS or compare your options.
Common questions about HRIS and ATS
Is an ATS part of an HRIS?
Sometimes. Some HRIS products include applicant tracking, and some don't. Ask whether hiring is built in, and whether a new hire's details carry over to their employee record.
Which should a small business buy first?
Start with your biggest problem. If open jobs and lost applicants hurt most, start there. If paperwork and records hurt most, start there. A system that does both saves you from choosing.
Can I use an ATS and an HRIS together?
Yes, plenty of companies do. Check how new-hire details get from one to the other, because retyping them is where mistakes creep in.
Does HRGP replace my applicant tracking system?
It can. Applicant tracking is built into HRGP, with hiring steps, texting, interview scheduling and AI interviews. You can import applicants from a spreadsheet.
