Vendor Due Diligence (VDD)

A due diligence report commissioned by the seller and made available to potential buyers, designed to accelerate the sale process.

Also known as: VDD, Sell-side due diligence

One-line definition

In a VDD, the seller's advisers produce a full financial (and sometimes commercial) due diligence report before buyers submit bids, allowing a faster, cleaner process.

Why sellers use it

  • Reduces management disruption (one set of Q&A instead of many).
  • Gives buyers confidence, supporting higher bids.
  • Allows deal to close faster once exclusivity is granted.

Limitations

Buyers know the report was commissioned by the seller, so they apply their own judgement and often run a focused confirmatory review on top.
