What is the best ATS alternative for UK recruitment agencies that want to own their system?

Bottom line

UK recruitment agencies pay £80–165/seat/month for ATS and CRM systems that are, at core, candidate and client databases with kanban pipelines, email sequences, and job board posting. A custom replacement covering the same scope typically costs £40,000–£50,000 total shared across ~5 agencies. Annual running cost is ~£3,000 flat. For a 15-recruiter agency on Firefish (~£110/seat), break-even is inside 12 months — and your candidate data never leaves your own system.

What scope is included in a custom recruitment ATS?

Candidate CRM, job pipeline, job board posting, email sequences, and a client portal.

Standard ATS scope: candidate and client CRM, job workflow (pipeline stages, kanban view), job board multi-posting (CV-Library, Reed, Totaljobs via API aggregators), email and SMS candidate sequences, interview scheduling, CV parsing (via commodity OCR/NLP API), a client shortlist portal, and KPI reporting. Optional: branded career site, LinkedIn Chrome extension, and temp shift management.

Why recruitment agencies are strong replacement candidates

Candidate data is your biggest asset — keeping it on your own system is a competitive advantage.

Your candidate database — years of sourced, screened, and placed contacts — is your core asset. On a SaaS vendor's servers, the vendor can change access terms, raise prices knowing you cannot easily leave, or hold your history hostage at renewal. A custom ATS on your own isolated instance means your candidate data is permanently, unconditionally yours.
