A complete guide to Applicant Tracking Systems (ATS)

If you hire occasionally, spreadsheets and inbox coordination can work. But as hiring volume and process complexity increase, those systems start to break.

That's where an Applicant Tracking System (ATS) comes into the picture — designed to replace fragmented hiring coordination with structure, visibility, and shared accountability.

Whether you're in the market for one or just beginning to learn what an ATS can or cannot do, you're in the right place.

This guide covers everything you need to know about ATS platforms, including:

• What an ATS is, its key benefits, and misconceptions
• When you actually need an ATS and what its ROI looks like
• Types of ATS on the market and how they differ from HRIS and CRM tools
• How to choose the right platform and maximize adoption

What is an Applicant Tracking System? 

An applicant tracking system (ATS) is a software application that helps companies structure, manage, and scale their hiring process. It gives recruiters and hiring managers the tools to attract, assess, and hire candidates more efficiently.

What does an ATS do?

An applicant tracking system helps teams run hiring in a structured, repeatable way so decisions don’t rely on inbox coordination or one person holding the process together.

For small to medium-sized businesses (SMBs), an ATS becomes the central system that keeps hiring consistent across roles, teams, and stakeholders. It gives recruiters and hiring managers shared visibility into where candidates are, who’s involved, and what comes next — even as hiring volume increases.

In practice, an ATS helps teams:

• Centralize all candidate information in one place to review applicants, track progress, and assess role fit.
• Create structured hiring stages for each role using tailored, visual pipelines.
• Manage multiple roles across multiple departments with customizable pipelines.
• Coordinate interviews, feedback, and approvals across teams.
• Evaluate candidates with shared scorecards and evaluation templates.
• Track ownership, decisions, and next steps so responsibilities and handoffs are clear.
• Maintain visibility into hiring progress by showing real-time status across roles, stages, and teams.

This structure allows teams to hire consistently and collaboratively — without adding unnecessary complexity or slowing down decision-making.

Who is an ATS for? Is an ATS only for recruiters?

An ATS helps both recruiters and hiring managers stay aligned throughout the hiring process by working as a shared system — keeping everyone involved without relying on emails or manual follow-ups.

It helps recruiters manage pipelines, coordinate hiring activities, and run day-to-day hiring workflows, including reviewing applications, advancing candidates through stages, and coordinating interviews.

On the other hand, an ATS helps hiring managers review candidates, provide structured feedback, and see when their input is required at each stage.

ATS vs recruiting CRM: What’s the difference?

An applicant tracking system (ATS) supports end-to-end hiring by providing teams with tools to manage applications, pipelines, internal collaboration, and candidate communication.

In contrast, a recruiting Candidate Relationship Management (CRM) software focuses on proactive talent engagement — helping teams organize, nurture, and re-engage passive candidates and strong past applicants who may be relevant for future roles.

Depending on the provider, some ATS platforms also let you build and nurture talent pools — making a separate recruiting CRM unnecessary.

So the key difference isn’t the type of candidates each tool helps manage, but the depth of workflow and engagement tools each provides.

Key benefits of an Applicant Tracking System (for employers)

The benefits of an applicant tracking system go beyond simply managing applications in one place.

When used consistently, an ATS centralizes hiring workflows, reduces manual coordination and tool switching, and brings structure and visibility to the hiring process — improving both internal workflows and candidate experience.

Here’s a breakdown of how an ATS benefits teams:

1. Reduced administrative workload

At its core, an ATS removes manual, repetitive tasks that slow down recruiters and hiring managers. When implemented well, it cuts back work by helping you:

• Publish job postings to multiple job boards from a single platform
• Automatically collect, store, and organize candidate data
• Automatically parse resumes and applications to speed up initial screening
• Schedule interviews more efficiently using shared availability
• Record interview feedback and screening outcomes in one place
• Manage offers and collect e-signatures digitally (depending on the vendor)

By centralizing these workflows, recruiters spend less time on coordination and admin — and more time evaluating candidates and partnering with hiring managers.

2. Improved candidate experience

An ATS improves the candidate experience by bringing structure and consistency to how candidates are reviewed, communicated with, and progressed through the hiring process.

In practice, this helps teams deliver:

• Timely, automated communication at key stages, so candidates aren’t left guessing
• Clearer expectations and next steps through standardized hiring stages
• Greater visibility into candidate status, reducing follow-ups and uncertainty
• More consistent evaluations using shared scorecards and screening criteria
• Faster decisions as screening, feedback, and approvals happen in one system

This shifts the candidate experience from ad hoc and unpredictable to clear, consistent, and professional — even as hiring volume increases.

3. A more efficient recruitment process

Beyond individual tasks, an ATS also improves how the entire hiring process operates across roles and teams.

By centralizing data and automating key steps, teams gain:

• A single source of truth for all current and past candidates
• Better collaboration between recruiters, hiring managers, and HR
• Visibility into where candidates drop off, get delayed, and other recruitment metrics
• Consistent workflows across roles and teams
• An always-on system to manage hiring as volume increases

Over time, this process-level visibility makes it easier to identify bottlenecks, standardize best practices, and scale hiring without adding unnecessary complexity.

4. Better hiring outcomes

Ultimately, the value of streamlining your recruitment process with an ATS shows up in hiring results. As a result, an ATS supports:

• Shorter time-to-hire. Faster decisions reduce productivity gaps and prolonged vacancies.
• Improved cost-per-hire. Less manual effort, fewer delays, and better channel visibility help control recruiting spend.
• Better quality-of-hire. Consistent evaluation and clearer feedback improve decision-making, which in turn impacts performance, ramp-up time, employee retention, and hiring manager satisfaction.

Keep in mind, though, that each benefit depends on more than the software itself — it also relies on a clear recruitment strategy and consistent use of the system in your day-to-day.

What does an ATS not do? 4 misconceptions about ATS tools

A few common misconceptions about what an ATS can and cannot do exist.

Understanding these limits helps you decide when you need an ATS and evaluate tools more realistically — without setting the wrong expectations:

1. 

An ATS doesn’t get you an influx of candidates

An ATS helps you manage candidates; it does not create candidate demand.

If you’re struggling to attract applicants, buying an ATS alone will not solve the problem.

Attracting candidates depends on your recruitment strategy, employer branding, and how well your roles and company resonate with the market.

“Instead of investing huge amounts of money into your ATS, it’s worth having the conversation about how you’re going to fill the software with qualified candidates. Can the budget go some way to increasing the volume of qualified inbound candidates that will enable your recruiters to do a better job?”

Nathan Jefferson

Understanding your hiring market, what candidates care about, and how your company is positioned plays a far greater role in growing application volume than the software itself.

With this groundwork in place, an ATS can then help you execute the process more efficiently, but it cannot replace the strategy behind it.

2. An ATS doesn’t solve all your sourcing challenges

An ATS supports sourcing, but it doesn’t replace it.

Some ATS platforms allow you to distribute job postings across multiple job boards, which can reduce manual work. However, visibility alone does not guarantee applications.

If job descriptions are unclear, the application process is overly complex, or your employer brand is weak, candidates are unlikely to apply — regardless of the system you use.

"Yes, technology is certainly growing by leaps and bounds, but there seems to be this idea that every ATS is super intuitive and will magically make it easy to source candidates. You still need to vet, connect with and do your homework to find top talent."

Jessica Arias

VP of People and Culture at OnPay

While technology continues to evolve, sourcing still relies heavily on human effort. For many roles, especially niche or hard-to-fill positions, recruiters must actively identify, assess, and engage candidates.

3. An ATS is not going to help you pick the best candidate for the job, nor should it

An ATS helps teams organize candidate information and facilitate evaluation, but it does not make hiring decisions.

While some platforms include automated screening or AI-assisted features, effective hiring still depends on recruiters and hiring managers reviewing applications, evaluating fit, and deciding on next steps.

A well-configured ATS provides visibility into candidate pipelines, structured overviews, and centralized feedback — but the responsibility for hiring decisions remains human.

If candidates receive instant rejections without meaningful review, the issue lies in the process configuration, not the ATS itself.

“Having an ATS that could function better filled with incredible talent is far more interesting than a near-perfect ATS gathering dust. Focus on attraction first. Once you’ve done that, there’s a business case to suggest that you deserve the best-in-class ATS to support candidate experience.”

Nathan Jefferson

4. An ATS takes a lot of time to implement or switch

Researching and implementing an ATS does require effort. However, choosing a system that aligns with your workflows and scales with your organization can lead to significant time savings over the long term.

Many HR and recruitment teams hesitate to adopt or switch ATS software due to implementation concerns.

Past negative experiences with previous tools can also make change feel riskier.

“The strangest myth, and oddly enough a prevalent one about ATSs, is the claim that it is too time-consuming."

Maciek Kubiak

Head of People at PhotoAID

Having clearly defined hiring workflows and selecting an ATS that supports your unique organizational needs can significantly reduce implementation time, even improve time-wide software adoption.

Now that we’ve covered what an ATS can and cannot help you with, let’s dive into the types of ATS available on the market today.

Types of ATS on the market

ATS software broadly falls under four categories based on the hiring volume and complexity they support and the level of structure, flexibility, and scalability they offer.

Understanding these types helps you quickly narrow down which ATS solutions are realistic options for your hiring needs:

1. Lightweight ATS for basic hiring

Simple ATS such as Jazz HR and Teamtailor focus on simplicity and speed of setup.

They typically support job posting, basic pipelines, and applicant tracking, but offer limited workflow flexibility and reporting. Templates are also usually customizable to an extent.

Lightweight, basic ATS platforms work well for companies with occasional or low-volume hiring needs. But teams often outgrow the software as hiring volume, stakeholder numbers, or process complexity increase — making it less scalable.

Best suited for: Very small teams or early-stage companies hiring infrequently and transitioning away from spreadsheets-based recruiting.

2. Scalable ATS for growing teams

Scalable ATS platforms like Tellent Recruitee and Ashby support simple hiring needs while remaining flexible enough to scale as hiring volume and complexity increase.

They support customizable workflows, collaboration between hiring managers, HRIS integrations, and in-depth reporting — without requiring an enterprise-level implementation.

This category is often ideal for companies with 100-500 employees that want an easy-to-use, quick-to-implement ATS to support continued growth.

Best suited for: Growing SMBs that need structure without unnecessary complexity — hiring regularly across multiple roles and teams.

3. Enterprise ATS for large organizations

Enterprise ATS platforms like Workday Recruiting and SmartRecruiters are built for large organizations with complex compliance, approval chains, and global hiring requirements.

They offer deep configurability and advanced controls, but typically involve longer implementation timelines, higher costs, and more rigid workflows. For smaller teams, this complexity can slow hiring rather than improve it.

Best suited for: Large or multinational organizations with mature recruitment operations and in-house resources to handle system maintenance separately.

4. ATS modules within HR platforms for small teams

Some HR platforms, such as Personio and BambooHR, offer hiring features as an add-on module.

These recruiting modules only support basic hiring needs for small teams already using the broader HR system.

Because flexibility and reporting depth are limited, most growing teams often outgrow the module and integrate their HRIS with a standalone ATS.

Best suited for: Teams with simple hiring needs that want everything in one system.

How much does an ATS usually cost?

An applicant tracking system typically costs between $50 and $300 per month for small and mid-sized teams, depending on features, user count, and hiring volume.

More advanced or enterprise-focused ATS platforms are typically priced annually, with costs falling in the mid-five-figure range and extending into the low six figures per publicly available estimates.

That said, ATS costs are generally based on one of the following pricing models:

When does a company actually need an ATS?

You likely need an ATS when hiring volume, coordination, and reporting demands outgrow spreadsheets and inbox workflows. Practical signs include:

• You’re hiring 25–40 people per year (or more) or running 3+ open roles at once, with two or more stakeholders involved in decisions.
• Each role attracts dozens or hundreds of applicants, making manual tracking time-consuming.
• Hiring activity lives across email, spreadsheets, and shared documents, with no single view of candidate status or next steps.
  
• Candidates stall or disappear mid-process because ownership and follow-ups aren’t clearly tracked.
  
• Admin work dominates your week — scheduling interviews, sorting CVs, and chasing feedback across channels.
  
• You need hiring data to improve decisions, but reporting is manual, delayed, or incomplete.
  
• Compliance requirements increase, especially across regions, and candidate data is scattered across tools.

What is the ROI of an ATS?

The return on an ATS investment shows in five concrete ways:

• Time savings from reduced manual admin. An ATS cuts time spent on duplicate CV management, interview scheduling, reminders, screening, and chasing feedback — freeing recruiters to focus on hiring instead of coordination. These savings compound as you run more roles in parallel.
  
• Faster time-to-hire. Clear ownership, structured workflows, and faster coordination reduce productivity gaps and delays. Companies streamlining hiring with an ATS reduce time-to-hire by as much as 60%.
  
• Reduced candidate drop-off. 41.2% of candidates abandon applications, with smaller teams (under 250 employees) seeing 37.7% abandonment. An ATS improves communication and process clarity — reducing drop-off, shortening time-to-hire, and improving candidate quality.
  
• Better decision quality. Structured feedback and shared visibility support more consistent evaluations — reducing mis-hires, onboarding churn, inflated cost-per-hire, and reopened roles.
• Lower hidden costs of manual hiring. While spreadsheets and inbox-based hiring seem cheaper upfront, they create hidden costs as hiring scales — lost productivity, missed follow-ups, repeated scheduling, rushed decisions, and reactive hiring.

In practice, many teams discover that the cost of manual coordination already exceeds the cost of structured hiring software — making an ATS a cost-control decision rather than an added expense.

How do you choose the right ATS for your company?

Choosing the right ATS for your team comes down to how well it supports your real hiring processes now and in the future — not just the features it offers.

Follow these steps to select the best-fit ATS software for your team:

1. Assess your needs and budgets

Map your hiring volume, stakeholder involvement, and process complexity.

An ATS should match how your team actually hires today — and scale as collaboration and structure increase.

2. Identify must-have and should-have ATS requirements

Prioritize adoption, workflow flexibility, visibility, automation, reporting, and compliance. Make sure you also separate must-have ATS capabilities (structured pipelines, collaboration tools, reporting, HRIS integration) from “nice-to-have” features like advanced AI or layered approval workflows.

3. Shortlist the best ATS for your team size

Once you’ve defined your requirements, filter vendors based on how closely they align with your requirements.

Avoid evaluating every well-known platform. Instead, shortlist tools that:

• Are designed for your organization’s hiring volume and complexity
• Offer the workflow flexibility your team actually needs
• Integrate cleanly with your existing HRIS and tech stack
• Prioritize ease of use and fast implementation over feature overload
• Provide responsive, localized customer support and robust GDPR compliance.

4. Review vendors through structured demo questions

Move beyond feature tours. Ask vendors to demonstrate real workflows across recruiter and hiring manager perspectives, including:

• Feedback collection and accountability
• Workflow automation and reporting
• Scalability as hiring grows
• Implementation effort and ongoing admin workload

5. Test real hiring scenarios, usability, and adoption during trials

Have recruiters and hiring managers complete everyday tasks such as the following inside the system:

• Posting roles
• Moving candidates
• Collecting structured feedback
• Generating reports
  
  

Observe whether adoption happens naturally or requires constant HR intervention.

In a nutshell, choosing the right end-to-end ATS isn’t about finding the most advanced software. It’s about selecting a system your team will consistently use as hiring grows.

What mistakes do SMBs make when choosing an ATS?

SMBs often choose an ATS based on features, pricing, or brand reputation — rather than real hiring execution needs. The most common mistakes include:

• Choosing enterprise software that’s too complex for your current hiring volume
• Prioritizing advanced AI features over adoption and usability
• Underestimating implementation effort and ongoing admin workload
• Ignoring the hiring manager's experience during demos
• Failing to test real workflows during trials
• Overlooking integration gaps with HRIS or other hiring software in your stack

These mistakes rarely surface early, but they do so quickly after rollout, when hiring managers disengage, workflows break down, and adoption stalls.

Core features to look for in an ATS

The right ATS should offer the following core features to support your hiring operations:

• Candidate sourcing: Automated job posting, application pages that integrate into the candidate database, and employer brand management.
• Candidate management: Automatic uploading of candidate information and application documents into a central database, adding scheduling and screening information to candidate files, and storing current and former candidates' information to create talent pools.
• Pre-screening candidates: Keyword parsing of resumes and cover letters, automated screening of unqualified candidates, automated outreach, and interview scheduling.
• Screening candidates: Managing and hosting online tests and video interviews, storing and adding screening results to candidate files, and collaborating with recruitment team members on candidate profiles.
• Extending job offers. Generating and sending offer letters, collecting signed documentation, and adding them to candidate files.
• Employee onboarding. Assigning onboarding materials, tracking completion, and ensuring all compliance documentation is completed.
• Recruitment process optimization. Intelligence and metrics into every step of the recruitment process, allowing recruiters to identify bottlenecks and make efficiency changes.

As you evaluate different ATS platforms, use a list of important questions relating to your budget and core requirements to ask each provider.

This’ll help you determine which platforms to dig deeper into and which to remove from your shortlist.

We’ve a detailed guide sharing the questions to ask ATS vendors both as you demo the software and as you trial it.

How to implement an Applicant Tracking System

Choosing an ATS is only half the decision. Implementation determines whether the system improves hiring execution or simply introduces new process friction.

For most SMBs (50–500 employees), ATS implementation typically takes 2–8 weeks, depending on workflow customization, integrations (HRIS, email, job boards), and internal readiness.

But there’s a lot that can go wrong if you don’t have an implementation plan. For example:

• Teams over-customize before understanding daily usage
• Skip hiring manager training
• Treat go-live as the finish line instead of the beginning of adoption

To ensure smooth ATS implementation and adoption across teams:

1. Align stakeholders and prepare for adoption

Successful implementation requires cross-functional involvement.

HR should own workflow design, but hiring managers must be involved early to validate usability and ensure the system reflects real hiring behavior. IT or systems leads should support integrations, permissions, and data security.

Provide hands-on training before go-live and let hiring managers practice common tasks (reviewing candidates, submitting feedback, moving stages).

2. Define hiring goals and success metrics

Clarify what “success” looks like before rollout.

Set short- and long-term hiring goals and identify the metrics you’ll track (e.g., time-to-hire, pipeline visibility, feedback turnaround time).

Clear goals here help prevent the ATS from becoming a passive system rather than an active decision-making tool.

3. Leverage vendor implementation support

Many vendors assign implementation consultants or customer success managers to guide setup. Take advantage of this support to avoid configuration mistakes and unnecessary administrative burden.

Strong vendors also provide support documentation, video tutorials, training material, and in-platform chat assistance to help teams troubleshoot quickly.

A top-rated support team will also share tried-and-true best practices, helping you succeed with the platform long after implementation.

Remember, strong implementation isn’t about going live quickly; it’s about ensuring your team naturally uses the system once you do.

Wrapping up: An ATS is hiring infrastructure, not just recruiting software

An Applicant Tracking System is not just recruiting software — it is the system that structures how hiring operates as your team grows.

As hiring volume and process complexity increase, spreadsheets and inbox workflows begin to break down. That’s when an ATS helps, replacing fragmented coordination with shared visibility: tracking candidates, clarifying ownership, and keeping decisions connected.

But value doesn’t come from investing in a feature-rich software alone. It comes from choosing a system that reflects how your team actually hires, deliberately implementing it, and embedding it into daily workflows.

Without that system in place, hiring effort increases, but clarity and accountability do not.
