What it is
An Applicant Tracking System (ATS) is the software that stores and moves every candidate, job order and client record a recruitment desk works with, from first contact through to placement. For an agency, the ATS is the system of record: Bullhorn, RecruiterFlow, Vincere and Loxo are the platforms most UK and European desks run on, holding contact details, job orders, notes and every stage a candidate or account has moved through.
The word covers a second, related system too. Employers run their own ATS, tools such as Workday, Greenhouse, Lever or SAP SuccessFactors, to collect and filter inbound job applications before a role ever reaches a recruiter. A consultant meets both versions constantly: the one they log into every morning, and the one sitting inside a target company's tech stack.
Your ATS is where BD becomes real. Everything before that is still just research.
Why it matters
If a candidate conversation or client update never makes it into the ATS, it effectively did not happen: nobody else on the desk can see it, bill against it or hand it over when a consultant moves on. In 2026, 93% of recruiters report using an ATS, and the wider ATS market is valued at close to $7.94bn, a reflection of how central the system has become to running a desk at any scale.
The client-side version matters for a different reason. Which ATS a company runs, and whether it just switched vendors, says something concrete about its hiring maturity and volume: a small firm on a lightweight tracker behaves differently to an enterprise running Workday across five markets. A vendor switch itself is a real, if quiet, hiring signal, since replacing an ATS usually means a hiring push is coming, not that one just ended.
How boilr handles it
boilr does not replace your ATS. It feeds it. Every ICP-matched company, enriched contact and detected signal your AI sales employee finds is pushed straight into the ATS you already run, live today for RecruiterFlow, with other platforms including Bullhorn, Vincere and Loxo on the way, so nobody on the desk is copying rows between tools by hand.
Before anything lands, boilr checks for an existing company by domain and an existing contact by email. If a match exists, it enriches that record and appends the new signal instead of creating a duplicate, so the ATS stays the single clean source of truth rather than a place cluttered with near-duplicate rows.
On the client side, boilr also treats a target company's own ATS as part of its technographic profile, and a vendor switch as one of the signal types it watches for. The judgement of what to do with a fresh, enriched record still sits with you: boilr fills the ATS, you verify and send.
