Seller Financing: How to Protect Yourself When You Carry a Note

Agreeing to be paid part of the price later can win a deal, raise the headline value or close a funding gap. It also turns the seller into a lender to the business it just sold. These are the terms that decide whether that note actually gets paid.

Summary

Summary

  • A seller note, also called vendor finance or a vendor loan note, is part of the purchase price the buyer pays later, with interest, under a written loan agreement.
  • The seller usually ranks behind bank debt. If the business struggles, the bank is repaid first and the seller may be barred from collecting or enforcing for a period.
  • Protection comes from four places: security over assets, guarantees from people or companies with money, covenants that limit what the buyer can do, and information rights that show trouble early.
  • The intercreditor or subordination agreement with the senior lender often matters more than the note itself, because it decides when the seller can be paid and act.
  • Treat a seller note as a credit decision. Review the buyer's capital structure, cash-flow cover and fallback options as a lender would.

What seller financing is and why it is used

Part of the price, paid later, as a loan.

In seller financing, the seller accepts a promissory note for part of the purchase price instead of cash at completion. The buyer, usually the acquiring company or a new holding company, repays the note over an agreed term with interest. Unlike an earnout, the amount is fixed: the seller is owed it whether or not the business hits targets, as long as the buyer can pay.

  • Bridges a funding gapLenders and equity partners may not fund the full price. A note fills the gap.
  • Signals confidenceLenders and buyers often read a seller note as a sign the owner believes in the business.
  • Supports a higher priceBuyers may pay more in total if some is deferred.
  • Spreads taxIn some jurisdictions instalment treatment can spread the seller's tax over the payment period. Take tax advice; rules vary widely.

Where the note ranks

Most seller notes sit behind the bank.

If the buyer uses bank or private credit, the senior lender will almost always require the seller note to be subordinated: the senior lender is repaid first and holds first-ranking security. The terms are set out in an intercreditor or subordination agreement signed by the lender, the seller and the borrower.

RankLayerUsual position
1Senior debtFirst claim on cash flow and assets, first-ranking security
2Mezzanine or junior debt (if any)Behind senior, often with second-ranking security
3Seller noteSubordinated; may have second- or third-ranking security, or none
4Rollover and new equityLast; paid only after all debt
A typical capital stack after a leveraged sale

Subordination terms usually limit when the seller can be paid (for example, only if the borrower is within its covenants with the senior lender) and impose a standstill: a period during which the seller cannot enforce even if the buyer defaults on the note. Some lending programmes require seller notes to be partly or fully on standby, meaning no payments for a set time. Check the specific lender's requirements early, because they shape everything else.

The capital stack builder shows how each layer is funded and repaid; the deal structure comparison compares a note against cash, earnout and rollover structures.

The protections to negotiate

Security, guarantees, covenants and information.

ProtectionWhat it doesWhat to ask for
SecurityGives the seller a claim over assets if the note is not paidCharge over shares and assets, ranking behind senior; share pledge over the target
Personal or parent guaranteeSomeone with assets stands behind the noteGuarantee from the buyer's principals or parent company, with evidence of means
Financial covenantsEarly warning that cash flow is weakeningMinimum cash or leverage tests mirroring the senior facility
Negative covenantsStop the buyer moving value outLimits on dividends, management fees, new debt, asset sales and acquisitions while the note is outstanding
Information rightsLet the seller see trouble earlyMonthly management accounts, annual accounts, copies of lender compliance certificates
Events of defaultDefine when the note is in defaultMissed payment, insolvency, change of control, breach of covenants, cross-default to senior debt
AccelerationMake the whole balance payable on defaultFull acceleration, subject to the intercreditor standstill
Change-of-control repaymentGet paid if the business is sold againMandatory repayment on any sale of the business or its main assets
Set-off limitsStop the buyer withholding note payments for disputed claimsSet-off only for agreed or determined warranty claims

Commercial terms that change the risk

Interest, term, amortisation and size.

  • SizeThe larger the note as a share of the price, the more the seller is exposed. Keep cash at completion sufficient to meet personal priorities on its own.
  • TermShorter terms reduce exposure. Long terms with a single balloon payment concentrate risk at the end.
  • AmortisationRegular principal repayments reduce exposure over time; interest-only notes leave the full balance outstanding.
  • InterestShould reflect the risk of a subordinated loan. Some notes pay interest in kind (added to the balance) rather than in cash.
  • PrepaymentAllowing early repayment without penalty can help the buyer refinance and pay the seller out sooner.

A hypothetical comparison

Two notes of $2 million: hypothetical terms

Both notes have the same face value, but Note A reduces the seller's exposure quickly and gives recourse if something goes wrong. Note B leaves the whole amount at risk for five years.

Underwrite the buyer like a lender would

A note is credit; treat it as such.

  1. 1.Ask for the buyer's full sources and uses of funds, including senior debt terms
  2. 2.Review projected debt service: can the business pay senior debt and the note from cash flow, with headroom?
  3. 3.Check the buyer's track record and, if a sponsor, its capital partners; see evaluating independent sponsor offers
  4. 4.Understand any planned changes: new debt, acquisitions or management fees that compete with note payments
  5. 5.Agree a clear path if things go wrong: notice, cure periods and what happens under the standstill

The LOI value decoder separates cash at completion from deferred and contingent value, so a note can be compared fairly with other offers. For how deferred consideration fits into transaction budgeting, see M&A transaction costs.

Frequently asked questions

What is a seller note?

A loan from the seller to the buyer for part of the purchase price, repaid later with interest under a written agreement. It is also called vendor finance or a vendor loan note.

Is a seller note secured?

Only if negotiated. Sellers can ask for a charge over assets and a share pledge, usually ranking behind the senior lender, plus guarantees from the buyer's principals or parent.

What does subordinated mean for a seller note?

The senior lender is repaid first, and the seller's right to receive payments or enforce is limited by an intercreditor or subordination agreement.

What is a standstill period?

A period set in the intercreditor agreement during which the seller cannot enforce the note after a default, giving the senior lender time to act first.

How is a seller note different from an earnout?

A seller note is a fixed debt the buyer owes regardless of performance. An earnout is paid only if agreed performance targets are met.

Can a buyer stop paying a seller note because of a warranty claim?

Only if the documents allow set-off. Sellers should limit set-off to claims that are agreed or finally determined.
