For a recruiting agency, an ATS (applicant tracking system) is the record of candidates moving through specific jobs: applications, submittals, interviews, offers and placements. A recruitment CRM (customer or candidate relationship management) is the record of relationships over time: client contacts and business development, plus talent pools you keep warm before a job exists. Most agency software now sells both in one database; as of October 2026, Bullhorn, Recruit CRM, JobAdder, Loxo and Access Vincere Evo each describe their product as a combined ATS and CRM on their own sites.

So the real question for most agencies is not "ATS or CRM?" but whether one system covers both jobs well enough for how you work. This page defines each, compares them side by side, and lists what to check. For the wider question of which tools an agency needs at each size, see the recruiting agency tech stack guide.

What is an ATS in agency recruiting?

An applicant tracking system is organized around jobs. Each job has a pipeline of candidates, and each candidate on it has a status: sourced, screened, submitted, interviewing, offered, placed or rejected. For an agency, the ATS answers questions such as:

  • Who have we submitted to this client for this role, and on what date?
  • Which candidates are at interview stage across all our open jobs this week?
  • Has this candidate already been sent to this client by anyone on our team?
  • Which placements start this month, and which are still inside their guarantee period?

The submission date and the record of who submitted whom are not admin details for an agency. They are what settle fee disputes and stop double submissions, which is why they must live in one system with dates attached.

What is a recruitment CRM?

A CRM is organized around people and companies rather than jobs. In an agency it does two jobs, and the word is used for both:

  • Client relationship management: companies, hiring managers and other contacts, the history of calls and meetings, prospects you are pitching, fee agreements, and tasks to follow up.
  • Candidate relationship management: talent pools, tags and notes on candidates you are not actively placing, outreach sequences, and the record of when you last spoke.

The CRM answers questions such as which clients have not heard from you in sixty days, which hiring managers moved to a new company, and which senior candidates told you they would consider a move next year. None of those questions involve an open job, which is exactly why an ATS on its own cannot answer them.

What is the difference between an ATS and a CRM?

ATSRecruitment CRM
Organized aroundJobs and the candidates in each pipelinePeople and companies, whether or not a job is open
Core recordsJobs, applications, submittals, interviews, offers, placementsClient companies, contacts, prospects, talent pools, activities
Main usersRecruiters and resourcers working live jobsBusiness developers, account managers, and recruiters building pipelines
Time horizonWeeks: the life of a jobMonths and years: the life of a relationship
Typical metricsTime to fill, submittal-to-interview ratio, fill rateClient activity, new job orders, pipeline value, repeat business
What breaks without itNobody can prove who submitted whom, or whenClients go quiet without anyone noticing; candidates are rediscovered too late

The two halves need each other. A job order arrives from a client relationship (CRM), turns into a pipeline (ATS), and a placement becomes the reason to call that client again (CRM). Every handoff between two separate systems is a place for a fact to be retyped or lost.

How do the ATS and CRM sides work together on one placement?

An invented example of one job order, start to finish, showing which side holds each step:

StepWhat happensSide
1An account manager logs a quarterly call with a logistics client; the operations director mentions a planning manager vacancyCRM: activity on the contact
2The vacancy becomes a job order with fee terms and a hiring managerATS: new job linked to the client
3A recruiter searches a talent pool tagged "supply chain planning" and finds a candidate who said last spring she would move for the right roleCRM: talent pool and notes
4She is screened, submitted on a dated record, interviewed twice and placedATS: pipeline, submittal, placement
5A follow-up task is set for the end of the guarantee period, and the operations director goes on a list for the next quarterly callCRM: tasks and client history

In one system, all five steps sit on linked records and anyone can follow the thread. In two systems, steps 1, 3 and 5 live somewhere the recruiter working step 4 may never look.

Why do most agencies use one system for both?

  • One candidate record. The candidate you nurtured in a talent pool is the same person you submit next month. Two databases mean two records that drift apart.
  • Ownership and duplicates. Ownership rules depend on contact history and submission dates together. Splitting them across systems makes candidate ownership disputes harder to settle.
  • Client context on every job. When the hiring manager calls, the recruiter needs both the live pipeline and the relationship history on one screen.
  • Reporting. Questions such as "which clients produce our placements?" need job data and relationship data in the same place.

This is also why a corporate ATS is a poor fit for an agency. Corporate systems are built around one employer's openings and generally do not model clients, client contacts, fees or the same candidate going to several companies.

Which agency platforms combine an ATS and a CRM?

How each vendor describes its own product, from its own site as of October 2026. This is a definition page, not a buyer's ranking, so prices and features are not compared here.

ProductHow the vendor describes it
BullhornAn ATS and CRM for staffing firms, with candidates, jobs, shifts and clients in one platform and a CRM included to manage client relationships
Recruit CRMAn AI-powered ATS and CRM for recruitment firms, connecting candidates, client notes, open jobs and deals in one platform
JobAdderA complete recruitment ATS and CRM, usable on its own or with add-ons and partner integrations
LoxoOne talent intelligence platform with separate ATS and CRM modules alongside sourcing and outreach
Access Vincere EvoRecruitment agency software that combines CRM, ATS and automation in one platform

If you already use one of these, the integration pages for Bullhorn and JobAdder cover how interview notes get into them.

When does a separate CRM or ATS make sense?

  • Your ATS is weak at business development and switching is not possible this year. A sales CRM for the business development team can work if a single person owns keeping client records in step.
  • Most of your contract work runs through vendor management systems. Submittals then happen inside each client's VMS as well as your own system; see vendor management systems for staffing agencies.
  • You are an in-house team, not an agency. Employers often pair a corporate ATS with a separate candidate CRM for sourcing, because their ATS has no concept of clients to begin with.

In each case, decide which system is the record for each fact, such as submission date, ownership and client contact owner, and write it down. Two systems that both claim to be the record are worse than one imperfect one.

What should an agency check before choosing a system?

  1. The data model: clients, contacts, jobs, submittals, placements and, for contract desks, assignments and timesheets, as separate linked records.
  2. Duplicate detection on email and phone, with a warning before a second record or a second submittal is created.
  3. Submission history that shows who sent which candidate to which client and when, and cannot be edited after the fact.
  4. Email and calendar sync, so activity is logged without typing it twice.
  5. Talent pools and tags that a recruiter can search quickly, which is the CRM side most agencies underuse; how to build a talent pipeline covers the method.
  6. Notes that are searchable and structured, not only free text.
  7. Data export in a usable format, so you can leave if you need to.

Where do interview notes fit?

Screening and interview notes belong on the candidate record in your ATS, written so that a colleague can find them by search months later. How to write candidate notes in your ATS gives a structure per stage. If notes come from an AI note taker, check how they reach the ATS. Some tools write directly into ATS fields; others, such as Interview Signal, have no ATS integration and produce notes shaped for Bullhorn, Greenhouse, Lever or JobAdder that you paste in by hand. Either way, the ATS record is the one that counts.

Questions people ask

Do recruiting agencies need a separate CRM if they already have an ATS?

Usually not. Most agency software sold as a staffing ATS already includes a CRM for client contacts, business development and talent pools, and running two separate databases means typing the same facts twice. A separate CRM makes sense only when the ATS you have genuinely lacks a feature you depend on and cannot be replaced.

What is the difference between a staffing ATS and a corporate ATS?

A corporate ATS is built around one employer's own job openings and applicants. A staffing ATS also models clients, client contacts, fee terms, submittals of the same candidate to different companies, and placements or contractor assignments, which are the core records of an agency.

Is Bullhorn an ATS or a CRM?

Both. As of October 2026, Bullhorn describes its core product on its own site as an ATS and CRM for staffing firms, with a CRM included to manage client relationships alongside candidates, jobs and placements in one platform.

What belongs in the CRM side rather than the ATS side?

Anything about a relationship that is not tied to a specific open job: client contacts and their history, business development calls, prospects, and candidates you are keeping warm for future roles. Anything about a candidate's progress through a particular job, such as submittals, interviews and offers, belongs on the ATS side.
