Acquisition Debt vs Seller Note
Quick Answer
Acquisition debt comes from lenders; a seller note comes from the seller. Both can reduce the equity check, but they behave very differently. For sponsors, the decision affects purchase financing, reporting cadence, and who owns execution risk.
What is Acquisition Debt?
Acquisition debt is lender capital used to finance a business purchase. It can reduce the equity check, but it introduces repayment obligations, covenants, collateral, reporting requirements, and downside constraints. In practice, it answers this question: What third-party debt supports the purchase? The key operating test is whether the sponsor can support the workflow without creating avoidable reporting, governance, or closing friction.
What is Seller Note?
A seller note is deferred purchase price structured as debt owed by the buyer to the seller. It can bridge valuation gaps, reduce upfront equity, and keep the seller economically connected after close. In practice, it answers this question: Is the seller financing part of the purchase price? The key operating test is whether the sponsor can use it deliberately without confusing structure, economics, documentation, or investor expectations.
Key Differences
| Feature | Acquisition Debt | Seller Note |
|---|---|---|
| Core question | What third-party debt supports the purchase? | Is the seller financing part of the purchase price? |
| What it controls | The business has enough durable cash flow to support leverage. | Buyer and seller need a bridge between valuation, cash at close, and post-close confidence. |
| Operating burden | High, because lender reporting, covenants, amortization, and cash flow discipline continue after close. | Moderate, because payment terms, subordination, covenants, offsets, and disputes must be tracked. |
| Risk if misunderstood | Too much debt can turn an otherwise good acquisition into a liquidity problem. | Treating seller financing like bank debt can miss negotiation, alignment, and post-close relationship dynamics. |
| Decision context | Acquisition Debt matters most when the purchase financing discussion is about what third-party debt supports the purchase? | Seller Note matters most when the purchase financing discussion is about is the seller financing part of the purchase price? |
