Reference checks are the most skipped step in hiring. By the time a recruiter reaches them, the hiring manager has made up their mind, the candidate is waiting for an offer and the referees are hard to reach. So references become a quick phone call that confirms dates and adds little.
Reference check software changes the format. Instead of phone tag, each referee receives a short, structured online questionnaire, usually completed on a phone in a few minutes. Answers come back in a consistent format you can compare across candidates, and many tools flag suspicious references, such as a friend posing as a former manager.
This guide compares five tools on what their own websites say and what they publish about price. We have not run paid trials and have left out vendors' outcome claims where the method is not explained. Prices are as published in November 2026 and exclude tax.
Why references are worth doing properly
A bad hire is expensive. Gallup estimates that replacing a leader or manager costs around 200% of salary, compared with about 80% for technical roles and 40% for frontline staff. A structured reference check costs a fraction of that and can surface concerns an interview missed.
References also add evidence from people who have seen the candidate work over months or years, rather than for an hour. That is valuable for exactly the qualities interviews measure worst: reliability, how someone treats colleagues, and how they handle pressure over time.
Finally, references give you data. SHRM's 2025 benchmarking found that only 20% of organisations track quality of hire. Structured reference scores, collected the same way for every hire, are one of the few pre-hire measures you can later compare with performance.
Reference checks vs background checks
| Reference check | Background check | |
|---|---|---|
| Source | People who worked with the candidate | Records: criminal, credit, education, right to work, employment dates |
| Answers | How the person works: strengths, skills, behaviour | Whether facts are true and whether there are legal concerns |
| Typical provider | Reference check software or the recruiter | Background screening company |
| Consent rules | Candidate supplies referees | Formal consent and, in the U.S., FCRA processes |
Most employers need both. For screening providers, see our background check software comparison.

Crosschq
Crosschq's website describes "The Hiring Intelligence Platform for Talent Leaders". Its "360 Digital References" product aims to "turn references into structured hiring insight" and to "validate candidate soft skills, competencies, work experience and culture match". A separate fraud product looks for impersonation, deepfakes and suspicious behaviour across applications, interviews and references, and a quality-of-hire analytics module measures and benchmarks hiring outcomes.
- Strength: linking references to quality-of-hire measurement, so you can test whether reference scores predict performance.
- Integrations: partner integrations with Workday, SAP, Greenhouse, iCIMS and Oracle are listed.
- Watch for: no published pricing; customer logos suggest a focus on larger employers.
- Best for: talent teams that want references as part of a wider hiring analytics programme.
Xref
Xref's website describes "industry leading automated reference checking": candidates nominate referees, verified referees give feedback, and AI Reference Summaries condense the responses into one overview. It emphasises data protection, saying it meets GDPR requirements with "fully-compliant data collection and storage processes", holds ISO 27001 certification and stores data in local data centres.
- Strength: data handling for employers in regulated or privacy-conscious sectors, including government, health and aged care.
- Audience: talent acquisition teams, RPO providers, staffing firms and people teams, across not-for-profit, construction, retail and hospitality.
- Watch for: pricing is on a separate page rather than the home page; there is a free trial.
- Best for: employers and agencies that hire across regions and need clear GDPR compliance.
Checkster by Harver
Checkster now sits within Harver; the old Checkster address redirects to Harver's reference checking page, which calls it "Checkster, Harver's Reference Checking Solution". Candidates enter their own references, each reference completes a short survey in "just 2 minutes on a mobile device", and Harver advertises a "24-hour reference turnaround time". Its algorithm "determines the legitimacy of each reference", aiming to catch cases such as relatives posing as former managers.
- Strength: speed and fraud screening for high-volume hiring.
- Integrations: the FAQ says it "integrates with most ATS".
- Watch for: no published pricing.
- Best for: volume hiring teams that want references completed before candidates accept other offers.
SkillSurvey by iCIMS
SkillSurvey is now part of iCIMS: its old domain redirects to an iCIMS product page titled "Skills verification and reference checking", with a login for existing SkillSurvey customers. The page gives little product detail and no pricing.
- Strength: if you already use iCIMS, reference checking from the same vendor may simplify contracts and data flows.
- Watch for: ask iCIMS for current features, integrations beyond iCIMS and pricing in a demo, as the public page does not describe them.
- Best for: iCIMS customers.
Spark Hire
Spark Hire is best known for video interviews, but its applicant tracking system includes reference checks. Its pricing page lists Recruit Pro from $335 per month, billed annually, for companies with up to 200 employees, including video interviews and "automated reference checks". Recruit Growth starts at $499 per month for up to 500 employees.
- Strength: the only option here with published pricing, and references, interviews and applicant tracking in one tool.
- Watch for: it means adopting Spark Hire as your ATS; starting prices apply to companies with up to 50 employees, and annual contracts are required.
- Best for: small and mid-sized employers choosing a new ATS who want references included. Compare it with other systems in our applicant tracking software guide.
How to run reference checks that are worth it
1. Ask about the job, not the person in general. Write questions around the competencies the role needs: "How did they handle a missed deadline?" tells you more than "Would you rehire them?". Use the same questions for every candidate in the same role.
2. Ask for the right referees. Request at least one former manager and, where relevant, a peer or someone they managed. Set the expectation early in the process so candidates are not caught off guard.
3. Get consent and explain the process. Tell candidates when references will be requested, who will see the responses and how long they are kept. In the UK and EU, that is part of your obligations under data protection law; elsewhere it is simply good practice.
4. Time it well. Checking references only after a verbal offer limits their usefulness. Many teams now request them for the final two or three candidates so the results can inform the decision.
5. Read references alongside other evidence. References are one input. Combine them with structured interviews and work samples, and look for patterns rather than single comments. Our recruitment and hiring guide covers how the stages fit together.
6. Treat red flags fairly. A single negative comment may reflect a poor relationship rather than poor work. Follow up with the candidate before rejecting someone on a reference alone.
A sample reference questionnaire
Adapt these to the role. Ask referees to rate the first five on a scale (for example 1 to 5) and give a short example for each:
- How effectively did they plan and deliver their work against deadlines?
- How well did they communicate with colleagues, managers and customers?
- How did they respond to feedback or a change in direction?
- How strong were their skills in [the two or three skills the role depends on]?
- How well did they work as part of a team, including when there was disagreement?
Then add open questions:
- What would help them do their best work in a new role?
- In which areas would they benefit from development or support?
- In what capacity did you work together, and for how long?
Keep it to around ten questions. Referees answer a short, focused questionnaire far more carefully than a long one, and their answers are easier to compare.
What to ask vendors in a demo
- How are referees verified, and what happens when a reference looks suspicious?
- How long do references take on average, and what reminders are sent?
- Can we write our own questions, and can different roles use different questionnaires?
- Where is data stored and for how long, and how do candidates and referees exercise their privacy rights?
- Which ATSs do you integrate with, and what data writes back to the candidate record?
- How is pricing calculated: per check, per hire or per seat?
That last question matters. SHRM research found that 30% of HR leaders regret their most recent HR technology purchase. Run a pilot on one hiring team before committing.
How references fit your hiring timeline
SHRM puts median time-to-fill at roughly a month and a half. Phone references can add a week to the end of that, when you are most likely to lose candidates to faster employers. Online references sent to all finalists at once, with a 24- to 48-hour deadline, remove most of that delay.
Frequently asked questions
What is reference check software?
A tool that collects structured feedback from a candidate's referees through short online questionnaires, rather than phone calls, and presents the answers in a consistent report. Many tools also check whether references are genuine.
Are online reference checks as good as phone calls?
For consistency and speed, usually better: every referee answers the same questions, in writing, and responses can be compared across candidates. A short follow-up call is still useful when an answer raises a question.
How much does reference check software cost?
Most dedicated tools quote on request. Spark Hire publishes ATS pricing that includes automated reference checks, starting at $335 per month billed annually.
Can reference check software detect fake references?
Several tools try to. Harver says its algorithm determines the legitimacy of each reference, and Crosschq's fraud product covers references. Ask vendors how they verify referees and what you see when a check looks suspicious.
When should I check references?
For the last two or three candidates, before the final decision, so references can inform the choice rather than simply confirm it.
