Vendor Due Diligence

Due Diligence

Due diligence commissioned by the seller to prepare for sale and provide buyers with independent verification.

Full Definition

Vendor Due Diligence (VDD) is a due diligence exercise commissioned and paid for by the seller, with reports made available to prospective buyers. It has become increasingly common in UK M&A processes.

Types of VDD:

  • Financial VDD (most common)
  • Tax VDD
  • Legal VDD
  • Commercial VDD
  • IT/Technology VDD

Benefits for sellers:

  • Control the narrative
  • Identify issues early (fix or prepare explanations)
  • Accelerate buyer due diligence
  • Create competitive auction dynamic
  • Professional presentation of the business
  • Reduce management time with multiple buyers

Benefits for buyers:

  • Independent verification of key information
  • Standardised information for all bidders
  • Accelerated due diligence timeline
  • Reliance letter may be available

Limitations:

  • Seller-commissioned (potential bias perception)
  • May not cover buyer-specific concerns
  • Reliance letters have limitations
  • Cost borne by seller (often recovered in price)

UK practice: VDD is now standard in organised auction processes, particularly for private equity exits and corporate disposals. Quality of earnings VDD reports are especially common.
