What an ATS does
An ATS pulls together, in one place, the open roles, the candidates who apply, and where each one stands in the process: applied, interview, offer, hired.
Who needs one
If you run fewer than 3 openings a year, a spreadsheet is probably enough. If recruiting is central to the business, an agency or a corporate TA team, the volume of simultaneous processes makes a spreadsheet fall apart.
ATS vs. spreadsheet
A spreadsheet does not send reminders, does not screen CVs, and desyncs the moment two people edit it at once. An ATS fixes that, and adds a history per candidate that a sheet never keeps.
Frequently Asked Questions
No. It organises the work, but evaluating candidates stays human.

Probably not. An ATS pays off when the number of simultaneous processes gets hard to track by hand.
