The 27-item M&A closing checklist
A working closing checklist with 27 tasks across signing, pre-closing, closing, funds flow, and post-closing, with persistence and CSV export.
The window between signing and closing is where deals get lost. Not because the deal terms were wrong, but because someone forgot to obtain a third-party consent, the funds flow had a wire error, or the regulatory notice missed its deadline. The closing checklist is the single most useful document in the signing-to-closing window, and most of them live in a single associate’s Outlook calendar.
The M&A closing checklist on this site is a working version: 27 tasks across five phases (signing, pre-closing, closing day, funds flow, post-closing). Check off tasks as you complete them. The state persists in your browser. Export to CSV when you need to share with the team.
Why a structured list
A closing checklist is not a brilliant document. It is a complete one. The risk is in the items you forget, not in the items you remember. A structured list with the standard items pre-loaded means you start the engagement with the right scaffolding.
The 27 items are the standard categories: signing logistics, regulatory filings, third-party consents, R&W binder, escrow funding, wire instructions, officer certificates, secretary certificates, opinion letters, closing memorandum, post-closing integration tasks, transition services, working capital adjustments, indemnification escrow management, employee retention payments.
Every deal will have items that are not on the standard list (the asbestos disclosure, the foreign subsidiary tax election, the specific regulatory consent). Add those as custom tasks. The structured list is the floor, not the ceiling.
How a buyer-side associate should use this
Two weeks before signing: open the checklist. Read every task. Identify which tasks require lead time (regulatory filings, third-party consent solicitation, R&W binder negotiation). Calendar those items now.
Week of signing: confirm the funds flow with the banker and the wire instructions with the seller’s counsel. Confirm the officer certificate and secretary certificate signers are available.
Closing day: work down the checklist in order. Use the persistence to track real time so you can see what is blocking.
Post-closing: do not declare victory at funds receipt. The integration tasks, the transition services setup, and the indemnification escrow administration are the difference between a deal that closes and a deal that closes well.
Where this is not enough
The checklist is a tool for tracking. The judgment about which items to prioritize, which third parties are likely to drag, and which regulatory filings have substance versus form is the part that does not fit in a tool. That part is what counsel is for.
