Seller Financing: Compare Payments, Cash and Repayment Risk

Separate price, cash at close and future payments

A proposal can offer an attractive purchase price while asking the seller to finance part of it. The seller then has an ongoing credit exposure. The borrower must generate enough cash to operate the company and meet the payment terms. Compare the note as a separate instrument rather than adding its face amount to cash and treating the result as equally certain proceeds.

Begin with the cash actually paid at closing after agreed adjustments and payoffs. List note principal, any contingent consideration and other retained exposure separately. Show payment dates and amounts. If taxes, fees or debt payoffs are still estimates, label them as such. The seller's final after-tax proceeds require their own reviewed calculation.

The terms that belong in the comparison

A payment example with the timing made explicit

Illustrative only: a $100,000 seller note at 8% nominal annual interest, paid monthly and amortized over five years, has a regular payment of approximately $2,027.64. The periodic rate is 8% divided by twelve and there are sixty payments. The calculation does not establish an available rate, a permitted SBA structure or appropriate security.

If the same note matures after twenty-four regular payments, approximately $64,705.64 remains. That balance is due as a balloon in addition to the twenty-fourth regular payment under this example's convention. A five-year amortization is not a five-year maturity when the contract says otherwise. The buyer needs a specific source of cash or refinancing for the final balance.

Monthly rate i = nominal annual rate / 12
Payment = principal × i / (1 − (1+i)^−payment count)
Balance after k payments = principal(1+i)^k − payment × ((1+i)^k − 1)/i

At zero interest, the payment is principal divided by the number of payments. For real documents, check interest-day conventions, due dates, rounding, fees and the treatment of the last payment. The acquisition debt and cash-flow tool models monthly seller payments, delayed starts and a maturity balloon with its assumptions visible.

A delayed payment is not a complete description of standby

Specify whether interest is waived, accrued simply or compounded during the delay, when it is paid and whether it becomes part of the balance being amortized. Also identify any restriction on principal, interest, enforcement or collateral. The words “seller standby” alone do not answer those questions.

For a purely mathematical illustration, a $100,000 balance at 12% nominal interest with twelve months of simple interest added before payments begins becomes $112,000. Monthly compounding instead produces about $112,682.50. If interest is waived, it remains $100,000. Those cases have different later payments even though they began with the same face amount. They are scenario assumptions, not recommendations for lender documents.

Where an SBA-backed lender is involved, confirm the current procedure, lender policy and exact structure before assuming the note can count toward any required equity or receive payments. The public 7(a) program page supports eligible ownership changes; it is not a substitute for a written determination on a particular seller note.

Test the buyer's ability to pay every obligation

Start from earnings after required owner replacement, then bridge maintenance capital spending, taxes, working-capital investment and other cash needs. Include the senior loan and every paying seller obligation. A coverage ratio based on only the bank payment can overstate the buyer's available margin. First-year coverage may also conceal a payment start or balloon in a later year.

For seasonal trades, use monthly cash collections and payments. Roofing receivables, annual service agreements, landscape seasonality, payroll and fleet costs may not arrive on the same timetable as reported profit. A model should show the lowest cash month, note payment changes and the maturity month rather than relying only on an annual average.

Review downside causes separately. A departing technician, weak renewal cohort, margin fade on open projects and delayed collections require different responses. Do not assume the seller's willingness to finance a portion makes the credit risk acceptable or replaces diligence.

Compare two offers without disguising uncertainty

Prepare one row per offer with cash at closing, note principal, regular payment, payment start, interest/accrual, maturity, balloon, security, lender restrictions, contingent amounts and unresolved conditions. Keep a column for the documents supporting each term. Do not present a calculated present value unless the chosen discount rate and credit assumptions are explained.

An all-cash proposal and a higher price with a note can be attractive for different reasons. The choice depends on timing, expected collection, risk tolerance, taxes, protections and alternatives. This guide provides a comparison process; it does not decide which offer a specific seller should accept.

Closing and post-closing controls

1. Reconcile note principal to the purchase agreement and funds flow.
2. Verify the signed rate, dates, amortization and final maturity.
3. Coordinate senior-lender and counsel requirements.
4. Document security, guarantees, notices and payment instructions.
5. Retain an agreed schedule and track actual payments against it.
6. Calendar any reporting covenant, payment step-up, balloon or release condition.

Use the deal-structure guide, earnings bridge and acquisition underwriting guide to connect the note to the rest of the transaction. Resolve legal, tax and lender questions with the responsible advisers before signing.
