How to Choose an ATS: A Practical Guide for Growing Teams

If you’re hiring more than a handful of people per year, you’ve probably hit the limits of managing candidates in spreadsheets, email threads, and sticky notes. An applicant tracking system (ATS) brings structure to your hiring process — but with dozens of options on the market, choosing one can feel like a project in itself.

This guide cuts through the noise. No vendor rankings, no “top 10” lists — just a practical framework for evaluating which ATS actually fits your team.

Start With Your Hiring Volume, Not Feature Lists

The single biggest mistake companies make when choosing an ATS is starting with features. They browse comparison pages, get excited about AI-powered screening or advanced analytics, and end up paying for capabilities they’ll never use.

Instead, start with three numbers:

• How many roles do you fill per year? A team hiring 10 people annually has fundamentally different needs than one hiring 200.
• How many people are involved in hiring decisions? Solo recruiters need simplicity. Teams of five interviewers per role need collaboration tools.
• What’s your budget per hire? This helps you work backwards from what you can actually afford.

A company hiring 15 people a year with two hiring managers doesn’t need enterprise workflow automation. They need something that keeps candidates organised and makes scheduling interviews less painful.

The Four Questions That Actually Matter

Once you know your scale, evaluate every ATS against these four criteria:

1. Can your team actually use it?

The most feature-rich ATS is worthless if your hiring managers won’t log in. Look for:

• How long does it take a new user to post a job and review applicants?
• Can hiring managers leave feedback without training?
• Is the mobile experience functional (not just “available”)?

Request a trial and have your least technical hiring manager try it for a week. Their experience matters more than the sales demo.

2. Does it integrate with what you already use?

Check integration with your specific tools, not just the vendor’s integration page count. Key integrations to verify:

• Your email provider (Gmail, Outlook)
• Your calendar for interview scheduling
• Your job boards (LinkedIn, Indeed, or niche boards for your industry)
• Your HRIS or payroll system, if you have one

An ATS with 500 integrations is irrelevant if it doesn’t connect to the three tools your team uses daily.

3. What does it actually cost — fully loaded?

Recruitment software pricing is notoriously opaque. When evaluating cost, account for:

• Per-user vs. per-job pricing — Per-user works if you have few recruiters and many jobs. Per-job works if many people need access but you hire infrequently.
• Feature tiers — The “basic” plan often lacks essentials like reporting, custom workflows, or more than one job board integration.
• Implementation and onboarding costs — Some vendors charge thousands for setup.
• Contract length — Monthly flexibility vs. annual discount. For a first ATS, monthly is usually worth the premium.

Always calculate the total annual cost at your expected usage level before comparing.

4. Can you get your data out?

This gets overlooked until it becomes a crisis. Before committing, ask:

• Can you export all candidate data as a CSV?
• What happens to your data if you cancel?
• Is there an API if you need to build custom reporting?

Vendor lock-in is real in recruitment software. A good ATS makes it easy to leave — which, paradoxically, is a sign they’re confident enough in their product that they don’t need to trap you.

When Free Plans Make Sense (and When They Don’t)

Several ATS platforms offer free plans or generous free tiers. These can be excellent for small teams, but watch for limitations:

• Job posting limits — Free plans often cap at 1-3 active jobs. Fine for a 10-person company, useless for a staffing agency.
• Candidate storage limits — Some free plans purge candidate data after 30-90 days.
• Branding — Free plans typically show the ATS vendor’s branding on your career page.
• Support — Expect email-only support with slow response times on free plans.

If you’re hiring fewer than 5 people per year, a free plan is likely sufficient. Above that, the limitations usually start costing you more in workarounds than a paid plan would.

Red Flags During the Evaluation Process

Watch for these warning signs when evaluating vendors:

• No public pricing — If a vendor won’t show pricing without a sales call, expect enterprise pricing and aggressive sales follow-ups. This isn’t always a dealbreaker, but it signals that the product is likely designed for larger organisations.
• “Custom” everything — If basic features require professional services to configure, ongoing costs will be significant.
• Demo-only, no trial — A vendor confident in their product will let you try it. Demo-only usually means the product requires hand-holding.
• Long-term contract pressure — Pushing for multi-year contracts during initial conversations is a red flag, especially if you’re a first-time ATS buyer.

Making the Final Decision

After narrowing to 2-3 options, the decision often comes down to this: which one will your team actually use consistently?

The “best” ATS is the one that gets adopted. A simpler tool that every hiring manager uses will outperform a powerful one that only the recruiter logs into.

Run a structured trial with your actual team. Post a real job (or a realistic test job), process some test candidates through the full workflow, and gather honest feedback. The right choice usually becomes obvious.
