The Pre-Diligence Package
The set of records a buyer will demand during due diligence, assembled before you go to market so that disclosure is fast, clean, and on your terms.
What It Is
A pre-diligence package is the body of information an acquirer will eventually inspect during due diligence, gathered and organized in advance rather than scrambled together after an offer lands. Warrillow places it in his "packing list," the things to consider before you start: clean financials, contracts, customer and revenue data, organizational charts, and standard operating procedures, all ready before the first buyer ever appears. McDannell frames the same discipline as starting from the end and reverse-engineering the exit so the business is sale-ready, not merely for-sale.
The core instruction Warrillow borrows from Barefoot Wine's Michael Houlihan is blunt:
"You have to do your acquirer's due diligence for them."

Why It Protects Momentum
A sale has a tempo. Warrillow calls the forward tempo deal momentum, and its opposite, deal fatigue, sets in when both sides tire and start questioning the deal. Every information request a seller fumbles, every document that takes two weeks to produce, bleeds buyer enthusiasm and gives diligence room to drag. A package built in advance lets the seller answer requests in hours instead of weeks, keeping the deal moving while leverage is still high.
McDannell makes the cost of skipping this preparation concrete. As McDannell argues, going to market unprepared all but guarantees a poor outcome:
"Most exits are destined for a below average sale the second they hit the market."
McDannell, Get Acquired, ch. 2
Her remedy is the same as Warrillow's: have the financials, tax returns, bank statements, SOPs, and intellectual property organized before due diligence begins, then wait for the buyer's checklist (which is often largely not applicable to a smaller business).
How It Creates Leverage
Beyond speed, a polished package changes how a buyer perceives the seller. Warrillow argues that thorough preparation manufactures the feeling of competition even where little exists:
"A professionally prepared pre-diligence package is a subtle but powerful way to create competitive tension for your business—even if none exists."
Warrillow, The Art of Selling Your Business, ch. 3
A seller who hands over crisp, reconciled records signals a sophisticated counterparty with options, the kind of seller a buyer cannot easily push around. The flip side is that disorganized records signal the opposite and invite a buyer to slow down, dig, and eventually retrade on price.
What It Is Not
The pre-diligence package is preparation, not disclosure. Having information ready does not mean handing it all over at once. McDannell distinguishes the early-stage data room from the later due-diligence folder, withholding sensitive details such as vendor and customer names until a buyer is vetted and committed. Warrillow's slow reveal makes the same point: information is currency, spent deliberately. The package is built early and completely; it is released slowly and selectively.
