ATS IMPLEMENTATION

Your ATS should work for you.
Not against you.

Most startups configure their ATS the way it comes out of the box and spend years working around the gaps. StackBuilders designs and implements the system around your actual hiring process, from platform selection through to team training and handover.

The problem

A broken ATS isn't a technology problem. It's a process problem.

The platform is rarely the issue. The way it's been configured, or not configured, usually is.

Pipelines built for the vendor, not for you

Default stages, generic fields, and out-of-the-box automations that don't reflect how your team actually moves candidates through a process.

Nobody trusts the data

Incomplete records, inconsistent stages, and fields that no one fills in mean reports are unreliable. Nobody uses them, and the problem compounds.

Recruiters and managers work around it

Spreadsheets, email threads, and Slack messages replace the ATS. The system becomes a record of what already happened, not a tool for running what's happening now.

Integrations that don't talk to each other

Your HRIS, calendar, LinkedIn, and job boards are all disconnected. Every hire creates manual data entry in at least three places.

Platforms

Independent advice on the right platform for your stage

No commercial relationships with any vendor. The recommendation is based entirely on your hiring volume, team size, and process complexity.

Series A–C favourite
Ashby
Best-in-class for data and automation. Excellent reporting, strong sourcing tools, and the most configurable pipeline design available. Higher learning curve, but worth it for teams that will actually use it.
Enterprise-ready
Greenhouse
Robust, well-integrated, and trusted at scale. Strong structured interviewing tools and a large partner ecosystem. Slightly less flexible but highly reliable.
Mid-market sweet spot
Lever
Clean UX with strong candidate relationship management features. Good balance of power and ease-of-use. Well-suited for teams hiring across multiple functions simultaneously.
Simple & fast
Workable
Fast to set up, easy to use, and cost-effective for earlier-stage teams. Less configurable than Ashby or Greenhouse, but more than enough for most sub-50-person companies.
How it works

Four phases. No shortcuts on the foundations.

The timeline depends on your current state, team size, migration complexity, and the platform selected. Most standard engagements run 6–12 weeks. Scope and timeline are agreed before any configuration begins.

1
Weeks 1–2

Discovery & Current State Audit

No configuration starts until we understand what you have, what you need, and what decisions need to be made before a single setting is changed. This phase resolves the questions that derail implementations later.

  • Audit of existing ATS: configuration quality, data integrity, and adoption gaps
  • Assessment of what existing data is worth migrating and what isn't
  • Mapping of hiring stages, role types, team structure, and stakeholder workflows
  • Platform selection with rationale, if not already confirmed
  • Architecture decisions resolved before build begins (permissions, entities, department structure)
  • Agreed scope document — the build doesn't start until both sides have signed off on it
2
Weeks 2–6

Configuration & Integration

The ATS is built to reflect how your team actually hires. Pipeline stages, custom fields, automations, scorecards, and integrations are configured in a staging environment. Nothing goes live until it's been reviewed against the agreed scope.

  • Pipeline design per role family (tech, commercial, ops, leadership, etc.)
  • Custom fields, tags, and data structures configured from scratch
  • Automation rules for candidate comms, stage transitions, and reminders
  • Integration setup: HRIS, calendar, LinkedIn, job boards, Slack
  • Scorecard, feedback form, and offer workflow configuration
  • Core reporting dashboards: time-to-hire, pipeline health, source effectiveness
3
Weeks 5–8

Testing, Training & Go-Live

End-to-end testing before anything touches live data. Training is role-specific: admins, recruiters, and hiring managers each get sessions built around how they'll actually use the system. A short parallel-running window is built in where complexity warrants it.

  • Full end-to-end testing across all role types and pipeline stages
  • Separate training sessions for recruiters, hiring managers, and admins
  • Recorded walkthroughs for each user type — permanent onboarding resource
  • Go-live with a structured cutover plan, not a switch-flip
  • Admin documentation: how to manage users, settings, and future configuration
4
Weeks 8–12 (post-go-live)

Hypercare & Handover

The go-live isn't the end. The first weeks in a new system surface questions and edge cases that can't be anticipated before users are in it. This phase ensures adoption sticks and the team is genuinely self-sufficient by the time the engagement closes.

  • 30-day post-go-live support window for questions, tweaks, and edge cases
  • Adoption check-in at two and four weeks to catch any gaps before they compound
  • 30-day retrospective: what's working, what needs adjusting, what to optimise next
  • Formal handover to internal owner with full configuration documentation

Investment

Scoped to your engagement.

ATS implementations vary significantly in scope. A platform selection for a 20-person company looks very different to a multi-country configuration with deep HRIS integration. Fees are agreed at the end of the discovery phase, once the full scope is understood.
