The CFO is the only person in the building who has to deliver this quarter's numbers and the diligence answers due Friday. Both jobs are full-time. The playbook is about not losing one to the other.
The Problem
An M&A or restructuring process consumes finance function bandwidth in a way few CFOs anticipate. Diligence demands data the team has never produced in that format. Working capital and cash flow models become live, daily artifacts. Reps and warranties require sign-off that the operating CFO is structurally exposed on. Banker, lawyer, and DD-provider Q&A volume is enormous and constant.
Meanwhile, the business continues. The board still expects the monthly close. Customers still need credit decisions. Lenders still want covenant compliance reporting. The CFO who tries to hold all of this together personally fails one of them — usually both.
What the Playbook Looks Like
First: structural separation of workstreams. Day-to-day finance and transaction finance need separate accountability — even if the people overlap. A 'Transaction Finance' team — even of two people, drawn from FP&A and treasury — owns the diligence response, the financial model, and the bidder Q&A. The standing finance organisation owns the close, controls, treasury, and reporting.
Second: a senior process owner outside the finance function. The CFO does not run the M&A process. The CFO supports it. Process ownership — the M&A advisor, the CRO, or the independent counsel — sits outside finance and absorbs the workstream coordination. Without this, the CFO becomes the integration point for everything and the operating finance function degrades.
Third: capacity decisions made early. Hiring temporary FP&A or treasury support 'just in case' is cheap. Backfilling under crisis is expensive and slow. The first thirty days of a transaction process are the right window for capacity decisions, not week eight.
Fourth: reporting discipline that does not bend. The board, the lenders, and the governance stack continue to require reporting. Bending it 'because of the deal' is the most expensive shortcut available. The reporting cadence becomes the rhythm that everything else snaps to.
Fifth: the discipline of saying no. Bidders, bankers, and lawyers will ask for everything. Half of it isn't material. The CFO who says yes to everything will run out of bandwidth before the deal closes. Saying no — well, with reasoning — is a finance leadership function.
Why This Is Worth Documenting
Most CFOs run their first major M&A or restructuring without a playbook. The patterns repeat — the diligence overload, the close that slips, the team burnout — but each CFO learns them in real time on the most expensive transaction of their career.
The pattern is not new. The protection is structure. The CFO who sets up the separation early, brings in capacity, and refuses to be the integration point for everything is the CFO whose business performance survives the transaction intact. That outcome is what the deal value depends on after closing — and increasingly, what bidders price in during diligence.
