A seller note can make the initial cash requirement look manageable while leaving a large payment at maturity. The balloon is a financing event that needs its own plan. It should not disappear behind a low monthly-payment figure in the acquisition model.
Write the obligation in plain language
Record original principal, interest rate, payment frequency, payment start date, amortization schedule, maturity date, and the balance due at maturity. Distinguish a note amortized over a longer period from a note actually due over that same period. Ask counsel and the lender to confirm the executed terms and how the note interacts with other financing.
Also identify any variable rate, payment deferral, mandatory prepayment, guarantee, security interest, or standby requirement. These provisions can change cash demands or available remedies. A term sheet is a starting point for review, not the final source of payment obligations.
Calculate the balance instead of guessing
Consider a fictional $300,000 note with 8% annual interest, monthly payments based on ten-year amortization, and a balloon after three years. Assuming standard monthly amortization, the monthly payment is approximately $3,640 and the remaining balance after 36 payments is approximately $233,500.
The payment amount is only part of affordability. Saving enough to cover that balloon evenly across 36 months would require roughly $6,487 per month before considering interest earned, taxes, or other uses of cash. This simple savings comparison is not a required contractual reserve; it exposes how much of the principal remains unpaid.
Test three repayment paths
- Operating cash: project the cash actually available after payroll, reinvestment, other debt, and owner requirements.
- Refinancing: identify the lender's likely documentation and underwriting process, while treating future approval, rates, and valuation as uncertain.
- Asset sale or outside equity: state what must be sold or raised, the expected timing, and what happens if proceeds are delayed.
Do not count the same dollar twice. Cash retained to fund the balloon cannot also fund equipment replacement or a distribution. Show the competing uses in one schedule.
Make the downside case specific
Reduce operating cash, delay the refinance date, and test a higher financing payment. Then ask whether the company can continue operating without relying on a discretionary extension from the seller. If an extension is important, have the transaction team address it in the documents rather than assuming goodwill will solve maturity risk.
Review the note alongside the seller-note payment calendar. The SBA's acquisition-planning resources encourage cash-flow diligence. The example here is arithmetic for evaluating a proposed structure, not a financing offer or a conclusion that a particular lender will accept it.
