The math of PE-backed dental roll-ups is built on synergy: same back-office, same procurement, same tech stack, lower cost per location. The math holds in the spreadsheet. The execution is where it breaks.
Each acquired group brings its own PMS, its own imaging, its own scheduling tool, its own integration tangle. The standardization plan usually lives on slide 47 of the LOI and gets handed to an ops team that doesn't have implementation resources. Eighteen months in, the portfolio is still running on five different stacks — and the original deal thesis quietly becomes a renovation project.
Why it's expensive
The cost isn't just the new platforms. It's the migration effort, the parallel-run period, the productivity loss while teams relearn workflows, the data clean-up that nobody scoped, and the staff turnover when change management is mishandled. None of these show up cleanly in the deal model.
What protects the thesis
Three things, in order:
- Diligence the tech stack the way you diligence the AR. Know what you're inheriting before you close.
- Have a standardization playbook ready at close. Not a plan to make a plan. A specific platform, a specific sequencing, a specific resourcing model.
- Run implementation as a portfolio function, not as a per-location project. One methodology, applied consistently. The cost goes down with every location after the third.
If technology spend isn't mapped to operational outcome, it's not an investment. It's an expense.
The PE firms doing this well treat implementation as core operating infrastructure — not as a vendor-managed afterthought. That is the only way the synergy math actually shows up in EBITDA.
