Best Practices and Mistakes When Buying an ATS: What Every HR Team Needs to Know
Selecting the right Applicant Tracking System (ATS) is one of the most consequential decisions an HR or recruiting team can make. The right platform can transform your entire hiring pipeline — reducing time-to-hire, improving candidate quality, and saving thousands of hours of manual work every year. The wrong one, however, can result in wasted budget, frustrated teams, and a painful migration process down the road.
Whether you're a first-time buyer or looking to replace an outdated system, understanding the core do's and don'ts of buying an ATS will set you up for long-term success. Below, we break down the most important best practices alongside the most common mistakes — so you can move forward with confidence.
The Do's: Best Practices When Buying an ATS
Do Ask for a Proper Budget
One of the first and most important steps in the ATS buying process is securing an adequate budget. Many HR professionals make the mistake of accepting whatever budget is handed to them without making a business case for a better investment. An ATS can deliver substantial ROI — from reducing reliance on recruitment agencies and cutting time-to-hire, to ensuring you attract and retain top-tier talent before competitors do.
Take the time to quantify the impact: how many hours does your team currently spend on manual resume screening? What is the cost of a bad hire, or the cost of a position sitting unfilled for weeks? Present these numbers to your finance department. While there are free ATS options available, they are generally designed for small teams with minimal hiring volume and offer limited features. A properly funded solution will scale with your needs and provide far greater value over time.
Do Think Long Term
An ATS is not a short-term purchase — it's a foundational piece of your recruiting infrastructure. If you choose wisely, you and your team could be using the same platform for five, seven, or even ten years. That's why it's absolutely worth investing significant time upfront to research, evaluate, and demo multiple vendors before making a commitment.
Rushing the decision to save time now often leads to far more costly problems later. Migrating from one ATS to another — including data transfer, retraining staff, and reestablishing integrations — is an expensive and disruptive process. Avoid this scenario by asking detailed questions during demos, requesting references from current customers, and making sure the platform aligns not just with your current needs but with where your organization is heading in the next three to five years.
Do Secure Internal Buy-In
Even the best ATS on the market will fail if the people using it don't support it. Before finalizing any purchase decision, it's critical to engage key stakeholders across the organization — including department heads, hiring managers, and members of the recruiting team who will use the system daily.
Internal resistance is one of the leading reasons new HR software implementations fail. People resist change, especially when they feel a tool has been imposed on them without their input. Involve stakeholders early in the evaluation process, gather their requirements, and make sure their concerns are addressed. When team members feel heard and see that the chosen platform solves real problems they face, adoption rates increase significantly.
Do Map Out Your Core Requirements
Before you start watching demos or reading vendor comparison articles, sit down and clearly define what your team actually needs. Create a structured list of must-have features versus nice-to-have features. Consider things like job posting automation, resume parsing, candidate communication tools, reporting and analytics, integration with your existing HRIS or payroll systems, and mobile accessibility.
Having a clear requirements document keeps your evaluation process focused and prevents you from being swayed by flashy features you'll never actually use. It also makes it easier to compare vendors side by side.
Do Evaluate Vendor Support and Onboarding
The quality of customer support can make or break your experience with an ATS. Ask vendors directly about their onboarding process, available training resources, response times for support tickets, and whether a dedicated account manager is included. A platform that offers robust onboarding and responsive support will help your team get up to speed quickly and minimize disruption to your recruiting operations.
The Don'ts: Common Mistakes to Avoid
Don't Buy Based on Price Alone
It can be tempting to choose the cheapest option, especially when budgets are tight. But selecting an ATS purely on cost — without fully evaluating whether it meets your needs — is a false economy. A low-cost tool that your team finds difficult to use, that lacks key integrations, or that can't scale with your growth will end up costing more in the long run through lost productivity and eventual replacement.
Don't Skip the Demo
Never purchase an ATS without first doing a live, hands-on demo — ideally with members of the actual team who will be using it. Screenshots and feature lists don't tell you how intuitive the interface is, how quickly reports load, or how the candidate pipeline actually flows in practice. Use demo sessions to test specific workflows relevant to your hiring process and pay attention to usability details that could affect daily productivity.
Don't Ignore Data Security and Compliance
Recruiting involves handling sensitive personal data from candidates, which means your ATS must comply with relevant data protection regulations such as GDPR, CCPA, or other local privacy laws. Always ask vendors about their data security certifications, encryption practices, and compliance features before making a decision. Failing to prioritize this can expose your organization to serious legal and reputational risk.
Don't Forget About Integrations
Your ATS doesn't operate in isolation. It needs to connect seamlessly with your job board accounts, background check providers, onboarding software, HRIS platforms, and communication tools like email and Slack. Before committing to a vendor, map out your current tech stack and confirm that the ATS you're evaluating supports native or API-based integrations with the tools you rely on most.
Final Thoughts
Buying an ATS is a significant investment that deserves careful, methodical attention. By following these best practices — securing adequate budget, thinking long term, building internal support, defining your requirements, and evaluating vendor quality — you position your team for a successful implementation and years of improved hiring performance. Equally important is avoiding common pitfalls like choosing on price alone, skipping demos, and overlooking compliance concerns.
Take the time to do it right the first time. Your future hires — and your recruiting team — will thank you for it.
