VDD (Vendor Due Diligence)

Sell-side commissioned diligence reports — financial, commercial, tech — delivered to bidders in the data room.

VDD reports are produced by independent firms on the seller's behalf and rebadged for buyer reliance after the deal. They compress the buyer's confirmatory diligence, support competitive tension, and let bidders move faster. Quality VDD also flushes out issues early so they can be addressed pre-marketing.
