In many mid-market transactions, an otherwise attractive deal fails not for lack of will but because of a financing gap. The buyer cannot raise the full purchase price from equity and bank debt, and valuation expectations sit at the upper end of the market. This is exactly where the vendor loan comes in: the seller defers part of the purchase price and effectively becomes the financier of their own transaction.
What a vendor loan does in an M&A deal
With a vendor loan, the seller does not receive the entire purchase price in cash at closing. Instead, a portion remains outstanding as a loan against the buyer, repaid with interest over several years. Typically the deferred share ranges between 10 and 25 percent of the price. For the buyer it reduces the immediate capital requirement and eases the bank financing. For the seller it sends a signal: leaving part of the price outstanding shows confidence in the company's future.
The vendor loan is therefore not a last resort but a deliberate structuring tool. In our M&A advisory we frequently use it as a building block in a layered financing structure, as described in our article on debt advisory and financing structures.
Terms, ranking and security
A vendor loan is negotiated like any loan, but with particular features. Interest usually sits above the bank rate because the loan is subordinated and the seller carries higher default risk, typically a market rate plus a spread of two to five percentage points. Maturities of three to seven years are common, often with a bullet repayment or an initial grace period so that the company's cash flow services the bank loan first.
Ranking is decisive. Banks almost always require a qualified subordination of the seller behind senior debt. The seller is only served once the bank has received its instalments. Anyone signing this should understand the consequence: in a crisis the vendor loan is last in line. Second-ranking share pledges or covenants can partly cushion this risk.
Distinguishing it from escrow, price adjustment and earn-out
The vendor loan is often confused with other deferral instruments but serves a different purpose. An escrow primarily secures the buyer's warranty claims and is not a financing tool. The purchase price adjustment corrects the price retroactively using closing-date figures such as net debt and working capital, changing the amount rather than the timing.
The earn-out makes part of the price contingent on future success and is therefore risky for the seller. The vendor loan, by contrast, is a fixed payment claim with interest, independent of future results, merely subordinated in rank. In practice these components are combined: part in cash, part as a vendor loan, part as an earn-out. Thorough sale preparation clarifies early which mix fits the seller's risk appetite.
When seller financing pays off
From the seller's perspective the vendor loan is a double-edged sword. It widens the buyer pool, often enables a higher total price and can produce tax-friendly cash-flow profiles. On the downside, the seller remains entrepreneurially tied to a buyer over whom they no longer have control. The buyer's creditworthiness and business model must therefore be examined as carefully as a bank would examine the seller.
We advise sellers to treat the vendor loan not as a mere concession but as a negotiable instrument with a price: a higher interest rate, shorter maturities, hard covenants and a clear default mechanism belong on the table, ideally accompanied by professional closing support.
FAQ
How large is a typical vendor loan? Usually between 10 and 25 percent of the purchase price. Higher shares occur but tend to signal a strained financing situation.
Must the seller agree to subordination? If a bank provides senior financing, qualified subordination is almost always a condition. Interest, security and the default mechanism remain negotiable.
What happens if the buyer becomes insolvent? The seller ranks behind the bank with a subordinated loan and may suffer a total loss in the worst case, which is why credit checks and second-ranking security matter.
