Recruiter-Native Stack Boundary

The boundary between an ATS built for recruiters and a general HR platform is where agency margin lives. Recruiter-native systems (Harbor for independent recruiters, Top Echelon for staffing firms) bundle candidate pipeline, client CRM, and outreach in one workspace, so a placement never requires syncing data across tools. General small-business ATS products such as JazzHR cover posting, screening, scheduling, and offer letters but stop short of client relationship management. For agencies serving recruitment or healthcare staffing clients, that distinction decides whether a retainer covers workflow optimization or a data reconciliation project. A concrete test: map every handoff in the client's hiring flow and count how many cross a system boundary. Each crossing is billable rework and a place where candidate records drift. Compensation platforms like Compport sit outside this boundary entirely, which is why pay-equity work usually arrives as a separate engagement rather than an ATS add-on.
