Seller Financing a Business Acquisition

Seller financing means the seller accepts part of the purchase price over time through a promissory note. It can improve alignment and bridge a financing gap, but it also turns the seller into a creditor and creates a continuing relationship that must be documented with precision.

Use the Note for a Defined Purpose

A seller note may demonstrate confidence in the business, reduce cash due at closing, satisfy financing structure, or keep the seller exposed to specific transition risk. The parties should understand which objective the note serves.

Seller financing should not make an unsupported purchase price appear affordable. The business must still support total debt service under a conservative case.

Negotiate the Complete Economics

Document principal, interest, amortization, maturity, payment frequency, prepayment, late charges, default interest, and any balloon payment. Model the schedule alongside senior debt, taxes, capital expenditure, and working capital.

A payment-free period may help transition cash flow but increases the later burden. Buyers should model the full schedule rather than focusing only on the first year.

Address Security and Priority

The parties and lenders must determine whether the note is secured, what collateral applies, whether personal guarantees exist, and how the seller's rights rank behind senior financing.

Subordination and standstill terms can limit the seller's remedies after default. These documents require coordinated legal and lender review before closing.

Connect the Note to Claims and Transition

The purchase agreement may allow offsets against note payments for defined indemnification claims, subject to notice and dispute procedures. Vague self-help rights create conflict.

If seller cooperation is important, document transition duties separately. Debt repayment and consulting performance should not depend on assumptions left outside the agreements.
