Owed Money? Your Legal Options for Unpaid Commercial Invoices

Unpaid commercial invoices begin with a client who is slow to pay but can quickly become a cash flow concern, particularly for a business that has already delivered the goods or completed the work in good faith. The temptation is to keep sending reminders and hope the account resolves itself, but Ontario law gives businesses a defined path forward and understanding that path early makes it far easier to recover what is owed.

At Gionet Fairley Wood LLP, we work with business owners across Barrie, Simcoe County, Muskoka, and Ontario who are owed money on invoices ranging from a single overdue account to a pattern of non-payment across multiple clients. Some come to us after months of informal follow-up. Others come the moment a client stops responding. In either case, knowing which legal tools are available, and when to use them, allows a business to act with confidence rather than frustration.

When Does an Unpaid Invoice Become a Legal Matter?

Not every late payment calls for legal action. A client who is a few days behind and communicating in good faith is different from one who has gone silent, disputed the invoice without explanation, or made clear they do not intend to pay. Before escalating matters, a business should confirm that the underlying obligation is sound. There must be a valid agreement for the goods or services provided, whether written, oral, or established through an ongoing course of dealing, and the amount claimed must be properly documented through invoices, purchase orders, delivery records, or correspondence.

Once those elements are in place and informal follow-up has failed to produce payment, an unpaid invoice becomes a debt that Ontario law allows a business to pursue through formal channels.

What Role Does a Demand Letter Play?

A demand letter prepared by a lawyer is often the first formal step, and it carries more weight than another reminder email from accounting. It sets out the amount owed, references the invoices and any prior attempts to collect, and gives the debtor a clear deadline to respond before further action is taken. A demand letter also serves an important legal function. It puts the debtor on notice and helps preserve the claim within the applicable limitation period.

Many disputes resolve at this stage. A debtor who has been avoiding the issue will often take a lawyer's letter seriously in a way they did not take internal collection efforts, and it opens the door to a negotiated payment plan without the cost of litigation.

What Documentation Strengthens an Unpaid Invoice Claim?

The strength of an unpaid invoice claim usually comes down to the paper trail behind it. A signed contract or purchase order establishes the underlying obligation, while the invoices themselves, delivery confirmations, and any correspondence acknowledging the debt help confirm that the amount claimed is accurate and undisputed. Records of collection attempts, including reminder emails, call logs, and the demand letter itself, show that the business made reasonable efforts to resolve the matter before resorting to litigation.

This documentation becomes particularly important if the debtor disputes the invoice or claims the work was never completed to the agreed standard. A business with organized records is in a far stronger position to prove its claim quickly, whether the matter proceeds through Small Claims Court or the Superior Court of Justice.

Where Is an Unpaid Commercial Invoice Claim Filed?

If a demand letter does not resolve the matter, the appropriate court depends on the amount owed. Claims of $50,000 or less generally proceed through Small Claims Court, a simplified and relatively cost-effective process designed to be accessible without extensive procedural steps.

Claims above $50,000 must be filed in the Superior Court of Justice. Claims between $50,000 and $200,000 typically proceed under the Simplified Procedure set out in Rule 76 of the Rules of Civil Procedure, which streamlines discovery and trial timelines compared to an ordinary action. Larger or more complex claims, particularly those involving disputed facts, multiple debtors, or related counterclaims, proceed under the ordinary civil procedure and may involve fuller documentary and oral discovery before trial.

Choosing the correct court and procedure at the outset avoids delays and unnecessary costs, and a litigation lawyer can advise on which route best fits the size and complexity of the claim.

What Happens After a Business Obtains a Judgment?

Winning a judgment confirms that the debt is owed, but it does not put money in the business's account. If the debtor still does not pay voluntarily, Ontario law provides several enforcement mechanisms. A garnishment order under Rule 60.08 of the Rules of Civil Procedure allows a creditor to collect directly from a debtor's bank account or from amounts owed to the debtor by a third party, such as accounts receivable. A writ of seizure and sale, filed with the sheriff, allows for the seizure of a debtor's personal property or the placing of a claim against real property they own.

Where the debtor is a corporation with ongoing financial difficulty, a court-appointed receiver may be used to take control of the debtor's assets and oversee an orderly recovery for creditors. Our creditors' rights lawyers regularly guide clients through each of these enforcement options and help determine which is realistically likely to produce results based on what is known about the debtor's assets.

How Long Does a Business Have to Collect on an Unpaid Commercial Invoice?

Under the Limitations Act, 2002, most claims for unpaid debts must be started within two years of the date the business knew, or reasonably ought to have known, that the invoice would not be paid. This discoverability principle means the clock does not necessarily start on the invoice due date if the business was reasonably still pursuing payment, but businesses should not rely on that flexibility. Waiting too long to escalate a stale account can permanently bar recovery, regardless of how clearly the debt is documented.

Can a Business Protect Itself Against Future Non-Payment?

While collecting on a current invoice is the immediate concern, most businesses that deal with non-payment once want to reduce the risk of it happening again. Clear written contracts with defined payment terms, deposits for larger projects, and interest clauses on overdue accounts all strengthen a business's position if a dispute arises later. Where appropriate, registering a security interest under the Personal Property Security Act can give a business priority ahead of other creditors if a client later becomes insolvent. These measures do not eliminate the risk of non-payment, but they meaningfully improve a business's odds of recovery when it does occur.
