When it comes to ATS (Applicant Tracking System) pricing, it can vary significantly based on the provider. Generally, the two common pricing models are based on either the size of the workforce or the number of user seats.

1. Per Size of Workforce: Some ATS solutions charge based on the number of employees in your organization. This model typically scales with your business size, where you pay a flat fee per employee or a tiered pricing structure that adjusts as your workforce grows.

2. Per User Seat: Other ATS providers charge based on the number of active users or seats accessing the system. This can be a good option for companies with a smaller recruiting team, as you only pay for the users who are actively using the system.

As for costs, ATS pricing can range widely. On average, you might expect to pay anywhere from $25 to $500 per month, depending on the features, the number of users, and the type of pricing model. For smaller companies, some ATS platforms offer pricing that can be as low as $100 per month, while larger enterprises might pay several thousand dollars a month due to the added features and integrations.

It’s always best to reach out to ATS providers directly for detailed pricing that fits your specific needs and to ask about any potential additional costs for features, integrations, or support.
