Three months ago, a Series B SaaS company in Austin reached out.
Their recruiting manager had a problem. Greenhouse was fine. But "fine" was costing them $18K/year in features they didn't use, integrations that broke quarterly, and a reporting layer that required a CS degree to operate.
They were evaluating Ashby. The sales deck looked clean. The analytics were sexy. The price was 40% lower.
But nobody on their team had migrated an ATS before. They didn't know the hidden costs. They didn't know what breaks in month three. They didn't know if the juice was worth the squeeze.
So I built them a migration calculator. Here's what it actually costs to switch ATS platforms: and when it makes sense vs. when it's a vanity project.
The Real Cost Breakdown
Cost Category | Greenhouse (Status Quo) | Ashby (Migration Target) | Notes |
|---|---|---|---|
Annual platform fee | $18,000 | $10,800 | Ashby pricing for 50-employee company |
Implementation & data migration | $0 (sunk) | $8,000–$15,000 | Depends on data cleanliness, custom fields, historical records |
Integration rebuild (Slack, LinkedIn, HRIS) | $0 (sunk) | $3,000–$5,000 | API changes, webhook reconfiguration, testing |
Team training & change management | $0 (sunk) | $2,000–$4,000 | Lost productivity during ramp, documentation rebuild |
Total Year 1 Cost | $18,000 | $23,800–$34,800 | Migration is more expensive in Year 1 |
Total Year 2 Cost | $18,000 | $10,800 | Break-even point |
3-Year TCO | $54,000 | $45,400–$56,400 | Depends on implementation complexity |
When Migration Makes Sense
Your current ATS reporting is actively blocking executive decisions (you can't answer "why is engineering hiring slow?" with data)
You're paying for 5+ integrations that break quarterly and require engineering time
Your team is growing 50%+ year-over-year and needs workflow automation your current tool can't handle
You have dedicated ops bandwidth to manage a 6–8 week transition
When It's a Vanity Project
The new tool has "better UI" but identical functionality
You're chasing a feature you'll use twice per year
Your team is <10 people and hiring <5 roles per quarter
You don't have 20 hours of dedicated project management time in the next quarter
The Tool Comparison
If you're evaluating, here's the honest breakdown:
Greenhouse | Ashby | Lever | |
|---|---|---|---|
Best for | Enterprise, complex hiring, heavy compliance | High-growth startups, analytics-driven teams, technical hiring | Mid-market, collaborative hiring, strong CRM |
Reporting | Robust but complex | Best-in-class, intuitive | Good, improving |
Implementation | Heavy, requires dedicated PM | Moderate, strong onboarding | Moderate, user-friendly |
Pricing | $$$ | $$ | $$ |
My take | If you're 200+ employees and need SOC 2/compliance depth, stay. If you're 50–150 and need speed + insights, evaluate Ashby. If you want the best CRM + sourcing integration, look at Lever. |
The Bottom Line
ATS migration is a $25K–$35K decision that takes 6–8 weeks and breaks at least one integration you forgot existed. Don't do it for a prettier dashboard. Do it when your current tool is actively blocking your ability to hire, measure, or scale.
