Your Legal Options When an Invoice Goes Unpaid

An unpaid invoice is a debt claim, and the recovery ladder is well established: internal follow-up, a formal demand letter, then a small claims lawsuit. The demand letter is not a formality — a properly drafted demand stating the amount, the legal basis, interest, and a firm filing deadline resolves a large fraction of commercial receivables without any court filing, because it signals that the cost of ignoring you is about to exceed the cost of paying you. Small claims court then handles the rest efficiently: limits vary by jurisdiction ($35,000 in Ontario, $12,500 in BC's Small Claims Court, and roughly $2,500–$25,000 across US states), filing fees are modest, and businesses can usually appear through an owner or representative.

Small claims frequently beats handing the file to a collections agency for debts of meaningful size. Agencies typically take 25–50% of anything recovered and have no more legal power than you do until a judgment exists; a small claims judgment, by contrast, unlocks real enforcement tools — bank account and receivables garnishment, and seizure of assets under a writ. Agencies make sense for high volumes of small consumer debts; for a five-figure B2B receivable with documentation, a demand letter followed by a small claims filing usually returns more money faster.

The Limitation Clock — and What Resets It

Debt claims expire. In most Canadian provinces the basic limitation period is two years from when the invoice became due and unpaid (Quebec allows three years, and some provinces six for certain claims); US states generally allow three to six years for written contracts, with wide variation. Nothing about chasing payment — calls, emails, final notices — pauses the clock. Creditors routinely lose enforceable debts by extending 'one more month' of patience past the deadline, so every aging receivable needs a diarized drop-dead filing date.

Two debtor actions restart the clock in most jurisdictions: a partial payment, and a written acknowledgment of the debt. This is why a debtor's email saying 'we know we owe the $8,400, things are tight' is worth capturing in writing — it can revive a claim approaching expiry and is near-conclusive proof at trial. If a debtor promises payment verbally, confirm it back by email; if they pay anything, record the date, because the most recent payment may be your true limitation start point.

Interest, Costs, and Collectability

You can generally recover more than the face value of the invoice. If your contract or invoice terms specify interest on overdue accounts, that rate applies — with the caveat that Canadian law requires an annual equivalent rate to be stated (a bare '2% per month' clause is vulnerable), and US states impose varying usury caps. Without contractual interest, courts award prejudgment interest at a statutory rate, and successful claimants typically recover filing fees and modest fixed costs on top of judgment. Build the full number — principal, interest, costs — into your demand letter so settlement talks start from the right baseline.

Before spending anything, assess collectability: a judgment against an insolvent debtor is a piece of paper. Check whether the debtor is still operating, search for other lawsuits and registered security against their assets, and confirm the exact legal entity that owes you — businesses across North America routinely invoice under trade names that don't match the corporation you must sue. If the debtor is sliding toward insolvency, speed is the strategy: an early judgment and garnishment beats a late claim filed into a bankruptcy where unsecured creditors recover pennies.

Frequently Asked Questions

How long can I wait before suing over an unpaid invoice?
In most Canadian provinces you have two years from when the invoice became due and unpaid; most US states allow three to six years for written contracts. A partial payment or written acknowledgment of the debt restarts the clock in most jurisdictions. Diarize a filing deadline well before expiry — negotiation does not pause it.
Does a demand letter actually work?
Often, yes. A formal demand stating the amount, interest, legal basis, and a firm deadline to pay before you file resolves a large share of receivables — it converts a payment chase into a credible legal threat. Even when it fails, it strengthens your court case by showing the debtor was given every chance.
Can I add interest and my costs to the claim?
Yes. Contractual interest applies if your terms state it (in Canada, an annual equivalent rate must be disclosed for it to be enforceable); otherwise courts award prejudgment interest at a statutory rate. Winning claimants also typically recover filing fees and modest fixed costs on top of the judgment.
Should I use a collections agency or small claims court?
For a documented debt of meaningful size, small claims usually returns more: agencies take 25–50% of recoveries and have no legal power beyond persistence until a judgment exists. A small claims judgment unlocks garnishment and asset seizure. Agencies suit high volumes of small consumer debts, not five-figure B2B receivables.
What if the customer disputes the quality of my work?
Then expect a defended claim and possibly a counterclaim or set-off. Your best evidence is acceptance: sign-offs, delivery confirmations, and emails showing they used the work without timely complaint. A customer who raised quality complaints only after the invoice arrived is in a weak position, and judges notice that timing.
What happens if they ignore the lawsuit?
If a properly served defendant files no defense within the deadline, you can request default judgment — often the fastest path to an enforceable judgment. The critical details are serving the correct legal entity at a valid address and proving the debt with clean paperwork.
Can I sue if the debtor's company might go under?
Yes, and quickly — but assess first. If bankruptcy or receivership starts before you collect, your claim becomes unsecured and recovery drops sharply. An early judgment plus immediate garnishment can capture money before insolvency; a late claim usually cannot. If they've already filed for bankruptcy, you file a proof of claim in that proceeding instead.
Do I need a lawyer to sue for an unpaid invoice?
Usually not for small claims — the process is built for self-represented parties, and businesses can typically appear through an owner or agent (Ontario also allows licensed paralegals). A lawyer becomes worthwhile when the debt is large, seriously disputed, involves a possible personal guarantee, or the debtor is insolvent.
