How it works in a data room
Integration planning often starts before closing, using what the buyer learned during diligence. After closing, many acquirers keep a data room running as the shared workspace for integration: the original diligence material, now fully owned, sits alongside 100-day plans, contract novation trackers and system migration documents. A searchable archive of the deal room is especially useful because integration teams are often different people from the deal team and need to find what was promised and disclosed.
Why it matters in a deal
Many acquisitions disappoint not because of price but because integration stalls. Customer contracts with change-of-control clauses, overlapping IT systems and key people leaving all erode value quickly. Diligence findings, particularly from technology due diligence, should flow straight into the integration plan rather than sit in a closed room. Our post-merger integration checklist sets out the first months in more detail.
Example
A private equity platform company in Ohio completes its third add-on purchase in two years. The day after closing, it converts the diligence room into an integration workspace: finance gets the target’s chart of accounts, HR gets the employment files, and IT gets the systems inventory. Each workstream posts weekly status reports in its own folder, and the sponsor’s operating partner reviews progress from the same place.
