30-day finance integration checklist for PE-backed bolt-on acquisitions. 26 tasks from close-date actions through first month-end close — the integration proof point for the sponsor.
| Phase | Focus | Timeline | Tasks | Status |
|---|---|---|---|---|
| Phase 1 | Immediate actions | Day 1 (close date) | 7 | Critical |
| Phase 2 | Financial access & control | Days 2–7 | 8 | In progress |
| Phase 3 | Integration architecture | Days 8–21 | 6 | Upcoming |
| Phase 4 | First close & reporting | Days 22–30 | 5 | Upcoming |
Four phases. Day 1 items complete before end of business on close date — no exceptions.
Four integration phases — financial control from close date through first reporting cycle
| Without this checklist | With this checklist |
|---|---|
| Day 1 financial actions are ad-hoc — items get missed when the deal team moves on | 7 close-date items with owners — complete before end of business |
| The new entity runs on its own reporting cadence for months | Platform reporting architecture installed by Day 21 |
| First month-end close is chaotic — nobody defined what "on platform standards" means | Day 30 close defined as the integration proof point with specific deliverables |
| Integration consultants charge $30K–$75K for financial integration workstreams | Self-service framework for $249 — reusable across every bolt-on |
The 100-Day Pack covers the full operational architecture for a platform acquisition — financial, KPI, governance, and sponsor visibility over 100 days. This checklist covers only the financial integration workstream for a bolt-on acquisition into an existing platform — 30 days, finance-only. They are complementary: use the 100-Day Pack at the platform level, and this checklist for each subsequent bolt-on.
The checklist accounts for this. Phase 2 includes ERP access and chart of accounts mapping specifically because bolt-on targets rarely run the same system as the platform. The goal is reporting alignment by Day 21, not full system migration.
Phase 1 (Day 1 actions) requires legal close to execute — bank access, vendor freeze, and signatory transfers cannot happen pre-close. However, you can pre-assign owners and stage the checklist before close so Day 1 items execute immediately.
The checklist was built from industrial bolt-on experience, but the financial integration tasks are sector-agnostic. Bank access, chart of accounts mapping, close calendar alignment, and reporting cadence are universal. The only industrial-specific considerations are in the working capital section.
