Key takeaways
  • When you accept payment over time, you become a lender, so repayment depends on the security and paperwork you put in place.
  • A PPSA registration lasts a set number of years from 1 to 25, or is perpetual, and you should diarize the expiry date and renew before it lapses.
  • Interest rates on a seller-financing note can raise criminal interest issues, and default charges on a mortgage on real property are limited.
  • If the buyer is insolvent and you intend to enforce security on all or substantially all of its inventory, accounts receivable or other business property, you must first send a notice and generally wait 10 days.

Buyers often ask the seller to finance part of the price. This is called a vendor take-back, or seller financing. Instead of receiving all the money at closing, you accept a promissory note and the buyer pays you over time, usually with interest.

That can help close a deal and may widen your pool of buyers, but it also leaves you exposed if the business struggles. This article explains how sellers commonly protect repayment through security, PPSA registration and careful default terms, and where the legal limits sit.

How seller financing works

In a typical arrangement, the buyer pays part of the price at closing and signs a note for the balance. The note sets out the amount, the interest rate, the payment schedule and what happens if a payment is missed. Without security, you are relying mainly on the buyer's promise to pay, so how well you are protected is worth confirming with a lawyer.

The form of security depends on what you sold and what the buyer owns. How it ranks against other lenders depends on your situation, so it is worth confirming with a lawyer.

Type of securityWhat it usually covers
General security agreementBusiness assets such as equipment, inventory and receivables.
Mortgage on real property (a vendor take-back mortgage)Land and buildings included in the sale.
Personal guaranteeA promise from the buyer's owner to pay if the company does not.
Share pledgeShares of the company bought, if shares were sold.

Many sellers combine several of these. Which mix makes sense depends on the deal, and a lawyer can help you choose and draft it.

Registering your security under the PPSA

Taking security over business assets is only the first step. Ontario's Personal Property Security Act has its own registration rules, and how they apply to your deal is worth confirming with a lawyer. Registration is a detail where small errors can be costly.

These rules come from the Minister's Order under the Personal Property Security Act, which was made on October 6, 2015 and came into force on November 16, 2015. Other PPSA rules also matter, including how priority works against a bank, and whether the note is paid off in stages. Ask a lawyer to confirm the right registration for your deal before closing.

Interest rates and default charges

It is tempting to set a high rate on the note to compensate for the risk. There are limits. Under the Criminal Code, a criminal rate is an annual percentage rate of interest, calculated using generally accepted actuarial practices, that exceeds 35 per cent on the credit advanced. A seller-financing note that charges interest above this can raise criminal interest issues unless an exemption applies.

SituationRule
Commercial credit to a borrower that is not a natural person, borrowing for a business purpose, more than $10,000 and up to $500,000Exempt if the APR does not exceed 48%.
Credit advanced of more than $500,000 under the same commercial exemptionThe regulation sets no rate cap.
Loans of $10,000 or lessNot within this commercial exemption.
TimingThe regulations and the 35% APR criminal rate came into force on January 1, 2025.

If the buyer is an individual, or if you take a personal guarantee, the exemption may not apply the same way. Have a lawyer check the structure before you set the rate.

For a mortgage on real property there is a second limit. The Interest Act says no fine, penalty or rate of interest that has the effect of increasing the charge on arrears of principal or interest secured by a mortgage on real property above the rate payable on the principal not in arrears may be stipulated for or exacted. A contract may provide for interest on arrears, but it may not exceed the rate payable on the principal not in arrears. In practice, this limits default-rate or penalty clauses in a vendor take-back mortgage on real property.

If the buyer defaults

Default terms should say what counts as a default, such as a missed payment, a sale of key assets or the buyer's insolvency, and what you can do about it. Your remedies come from both the agreements and the law, and you should not act on assets before getting advice.

If the buyer is insolvent, federal bankruptcy law adds a step. A secured creditor who intends to enforce security on all or substantially all of an insolvent person's inventory, accounts receivable or other property used in business must first send a prescribed notice of intention to enforce. This applies to a seller holding security over the buyer's business assets after a seller-financed sale if the buyer is insolvent.

Other rules, including those in the Personal Property Security Act, also govern how security is enforced, so the steps depend on the type of security and the facts.

What to do next

Frequently asked questions

What is a vendor take-back?

It is an arrangement where the seller accepts a promissory note for part of the price instead of being paid in full at closing. The seller then acts as a lender and is usually paid over time with interest. If the sale includes real property, the security may be a vendor take-back mortgage.

How long does a PPSA registration last?

The registration period is a whole number of years from 1 to 25, or a perpetual period. A registration can be extended or made perpetual, and a seller holding a security interest should diarize the expiry date and renew before it lapses.

Is there a limit on the interest I can charge on the note?

Yes. A criminal rate is an APR above 35 per cent on the credit advanced. Commercial credit to a non-natural-person borrower for a business purpose is exempt in certain cases, for example up to a 48% APR for amounts above $10,000 and up to $500,000. A lawyer can confirm how the rules apply to your deal.

Can I take the business assets back right away if the buyer defaults?

Not necessarily. If the buyer is insolvent and you intend to enforce security on all or substantially all of its inventory, accounts receivable or other business property, you must first send a prescribed notice and generally wait 10 days. A waiver of that period in the security agreement is ineffective, so get advice before acting.
