The short answer
Vendor due diligence, often called VDD, is a financial, tax and legal review that the seller commissions from independent advisers before going to market. It finds the issues a buyer would find, early enough for the seller to fix them, price them or explain them. Buyers usually treat the report as a head start and still do their own confirmatory diligence.
The situation
A Ludhiana auto parts promoter plans to sell a majority stake in his forging business next year. Two of his customers are large vehicle makers, his accounts are audited, and his CA has kept GST filings current. He has also heard from a friend whose deal fell apart in diligence: the buyer found an unpaid tax demand, a lease that had expired and a gratuity liability nobody had provided for, and the price came down by more than the issues were worth. The promoter wants to know whether he should look at his own business through a buyer's eyes first.
What a vendor diligence report usually covers
Financial
Quality of earnings, normalised profit, working capital trends, debt and debt like items, and how the management accounts tie to the audited accounts. This is the part buyers lean on most, because it shapes their price. See the quality of earnings review for what this work involves.
Tax
Direct tax assessments and open demands under the Income-tax Act, GST compliance, input credit positions, and any notices pending. Advisers also flag tax exposures that could follow the shares to a new owner.
Legal
Title to land and buildings, key contracts and their change of control clauses, licences and approvals, litigation, and corporate records under the Companies Act, 2013, such as share registers, board minutes and filings on the MCA portal.
Other areas, where they matter
HR and labour compliance, environmental approvals for a plant, IT and data protection. If the data room will hold employee or customer records, the DPDP Act, 2023 applies to how that personal data is shared. Our guide on diligence documents and the DPDP Act sets out the practical steps.
Why a seller would pay for it
Fewer surprises late in the deal
Most price chips happen after a buyer has invested time and money. A problem found by the seller's own advisers six months earlier can often be cured: a lease renewed, a filing regularised, a provision booked. A problem found by the buyer in week ten becomes a negotiation.
A faster, more even process
When several bidders receive the same report, they all start from the same facts. The seller's team answers fewer duplicate questions, and bids are easier to compare.
A clearer story about the numbers
Adjustments to EBITDA, such as a promoter's personal expenses or a one off legal cost, are set out once, with support. Buyers may still disagree, though the discussion starts from documented figures.
What it does not do
A vendor report is written for the seller, and buyers know that. They will test its findings, and they may ask the advisers for a reliance letter, which lets the buyer rely on the report under agreed terms and limits. Not every adviser will give one, and the terms vary.
VDD also does not replace warranties. A buyer will still ask for warranties and indemnities in the share purchase agreement, though the report can help the seller disclose known issues properly against them. Our guide on warranties and indemnities in Indian deals explains how disclosure works.
When it makes sense
VDD is most useful when:
- you expect more than one serious bidder
- the business has history that needs explaining, such as a past restructuring or a tax dispute
- you want to keep the timetable tight once buyers are in the data room
- the promoter's team is small and cannot handle several parallel diligence exercises
For a single, friendly buyer who already knows the business, a lighter internal readiness review may be enough. The deal readiness score is a quick way to see where you stand.
Running it well
Agree the scope in writing
List the areas, the period covered, the materiality level and the deliverable. A financial and tax review is common. Legal and HR work can be added where the business needs it.
Prepare the data room first
The vendor advisers will ask for much the same documents a buyer would. Building the folder structure now means the same room serves the sale later. The diligence checklist builder produces a request list by area, and what a due diligence request list contains explains each section.
Fix what you can before the report is final
If the advisers find an expired licence, renew it and let the report say so. A report that lists issues with a remedy already in place reads very differently to a buyer.
Keep the report current
A report dated nine months before signing will need a refresh. Plan for a short update before the data room opens.
How it looks for the Ludhiana promoter
In this sample case, the promoter's adviser scopes a financial, tax and legal VDD covering three years. The advisers find that a factory shed sits on land held in the promoter's personal name, and that one customer contract allows termination on a change of control. The promoter transfers or leases the land to the company on documented terms, and opens a conversation with the customer before any buyer is involved. When bidders arrive, both points appear in the report with the remedy described, and neither becomes a price discussion.
Where Synerger fits
On Synerger, the vendor advisers work from a request list in due diligence, each request has an owner and a due date, and every document lands in the same data room that buyers will later use, with access recorded. If you would like the Code Colonies consulting team to scope a readiness review, talk to an adviser.
