Every M&A transaction ends with a spreadsheet. Not the financial model that started the process, not the comparable companies analysis that justified the valuation, but a closing spreadsheet that tracks every condition, every deliverable, and every wire instruction required to get the deal done.
This spreadsheet is unglamorous. It is not the work that wins awards or gets discussed at conferences. But it is the document that determines whether a deal closes on time or slips by days or weeks.
A closing checklist for a typical software acquisition might have fifty to a hundred line items. Each one represents a task that someone needs to complete: a certificate to be signed, a consent to be obtained, a payoff letter to be delivered, an escrow agreement to be executed.
The job of managing this spreadsheet falls to the deal team, typically the lawyers and the M&A advisor working together. It requires relentless follow-up, attention to detail, and the ability to identify which items are on the critical path and which can be resolved in parallel.
Deals do not fail at this stage. But they do slow down. And in M&A, delay is the enemy of certainty. Every day between signing and closing is a day when something can change: a customer churns, a key employee resigns, market conditions shift, or the buyer’s board gets cold feet.
The last spreadsheet in the deal is not exciting. But it is essential. And the teams that manage it well are the ones that close on time, every time.
