Introduction
Even when a buyer and seller are excited to move forward, deals can stumble over financing. Maybe the bank won’t cover the full price, the buyer’s cash is stretched, or the working capital math doesn’t balance. In HVAC — where recurring service contracts, vehicles, and seasonal cash flow all matter — those gaps show up quickly.
That’s where creative structuring comes in. These tools don’t replace strong financials or trust, but they can keep a deal alive. This post isn’t legal, tax, or financial advice. It’s an overview of financing ideas sellers may encounter, with notes on how they tend to fit under SBA loans, cash deals, and alternative financing. Every deal is unique and must be negotiated with your advisors.
1. Seller Notes (Promissory Notes)
How it works: The seller finances part of the purchase price and the buyer repays over time with interest. Often structured as junior debt behind the bank.
- With SBA financing: Allowed, but seller notes counted as equity must usually be on standby (no payments for 2 years). Non-standby notes are treated as debt service.
- With a cash buyer: Very flexible — buyer brings cash, seller note fills the gap.
- With alternative financing: Common, since private lenders like to see sellers share risk.
HVAC angle: Notes may be tied specifically to fleet or equipment value, separate from goodwill.
Seller lens: Buyers may ask for a longer repayment term; sellers can negotiate interest rate, amortization, and prepayment rights.
2. Earnouts
How it works: A portion of the price is paid later if the business hits agreed performance targets.
- With SBA financing: Rarely works — SBA requires a fixed price.
- With a cash buyer: Flexible, especially when retention of customers is uncertain.
- With alternative financing: Investors may accept earnouts as part of a blended structure.
HVAC angle: Earnouts are often tied to retention of maintenance contracts, since those drive recurring revenue.
Seller lens: Negotiate what counts toward the target (gross revenue? service contracts retained?) and how performance is measured.
3. Holdbacks or Escrows
How it works: Part of the price is held in escrow for a defined period and released if no major liabilities surface.
- With SBA financing: Permitted if the terms are clear and finite.
- With a cash buyer: Simple and common.
- With alternative financing: Works, but lenders may want repayment before release.
HVAC angle: Protects buyers against warranty callbacks or unresolved customer claims.
Seller lens: Buyers often propose holdbacks; sellers can negotiate amount, duration, and release triggers.
4. Consulting or Employment Agreements
How it works: Seller provides transition help and receives compensation, separate from the purchase price.
- With SBA financing: Permitted if reasonable and tied to real transition duties.
- With a cash buyer: Very flexible.
- With alternative financing: Usually acceptable if structured cleanly.
HVAC angle: Useful if the seller holds the company license or has long-term client relationships.
Guardrail: These agreements have tax and employment law implications. They should be drafted by professionals.
5. Royalty or Revenue-Sharing Agreements
How it works: Seller receives a percentage of revenue (or margin) for a set period.
- With SBA financing: Not allowed. SBA requires fixed repayment schedules.
- With a cash buyer: Rare; most buyers prefer fixed payments.
- With alternative financing: More feasible with private investors.
HVAC angle: Occasionally used to align payments with seasonal swings in revenue.
Seller lens: Rare tool; if considered, negotiate caps, floors, and clear definitions. Must be carefully drafted by attorneys.
6. Equity Rollovers
How it works: Seller retains a minority stake in the business.
- With SBA financing: Not workable — SBA requires full seller exit.
- With a cash buyer: Possible if buyer is a private equity group or larger strategic operator.
- With alternative financing: Common in investor-backed deals.
HVAC angle: Sellers who see growth potential (adding new crews, entering new territories) sometimes like to keep a stake.
Seller lens: Negotiate governance rights, exit timing, and how profits are distributed.
Why These Structures Work
Creative financing isn’t about getting fancy — it’s about bridging gaps:
- Buyers want protection.
- Banks want predictable repayment.
- Sellers want fair value.
In HVAC, where service contracts, licensing, and warranties make the picture more complex, flexible structures can be the difference between a stalled deal and a signed closing.
Final Word
No two HVAC deals are alike. These tools are ideas for informational purposes only, they are not instructions. It is important to note that some structures fit with SBA rules, others only with cash or alternative financing. The right mix depends on your business, your buyer, and your advisors. Always check in with your CPA about tax consequences and be sure to bring in specialists such as business sale attorneys and business sale advisors to guide you along the way.
Handled thoughtfully, seller financing can do more than save a deal — it can give both sides the confidence to close.
