Someone owes you money and the polite reminders haven't worked, which is why you're now looking up how to write a demand letter instead of just sending another email that begins with "just following up." A demand letter is the formal written notice that a debt is due and that you intend to pursue the matter if it isn't paid, and it works because it signals a shift from casual collection to legal consequence. The good news is you don't need a lawyer to write one, and the better news is that a well drafted letter often gets paid without ever reaching a courtroom.
The tone matters more than most people expect. A demand letter isn't a rant, and it isn't a threat dressed up in formal language. It's a calm, factual statement of what's owed, why it's owed, and what happens next if payment doesn't arrive. The temptation to unload months of frustration onto the page is real, but a letter full of accusations and capitalized warnings reads like desperation, and desperation doesn't get paid. The goal is to sound like someone who has the facts on their side and the patience to follow through, not someone who has been stewing for weeks and finally snapped. Flat, professional, and slightly bored is the register you're aiming for.
Content follows a predictable structure. You identify yourself and the debtor, state the amount owed, explain the basis for the debt with enough specificity that the reader can't claim confusion, and set a deadline for payment. That deadline should be reasonable but firm, usually somewhere between 10 and 30 days depending on the circumstances and the history between you. You also state what you intend to do if payment isn't received, which typically means commencing legal proceedings, but you shouldn't overstate your hand or make threats you can't back up. A line like "I will be forced to consider all available legal options" is honest and sufficient. A line like "my lawyers will destroy you in court" is not, and it weakens your position if the letter ever becomes an exhibit.
Timing is its own discipline. A demand letter sent too early, before you've given the debtor any real chance to pay or explain, can look premature and undermine your credibility. A demand letter sent too late risks bumping up against limitation periods, which in most Canadian provinces run 2 years from when the debt became due. You want to send the letter after informal collection has clearly failed but well before any statutory deadlines start to bite. The letter should be dated, sent by a method you can prove, and kept on file with any response or non response noted.
For a small business owner doing this alone, the drafting itself isn't the hard part. The hard part is resisting the urge to treat the letter as the last word rather than the first real one. A demand letter is an invitation to settle, not a closing argument. It should leave room for the debtor to respond, propose a payment plan, or dispute the amount in good faith. If they do, you negotiate. If they don't, you move to the next step with a clear paper trail showing you gave them every reasonable chance.
Running a business means occasionally chasing money that should already be in your account, and doing it without a legal department means learning to write letters that carry weight on their own. That's exactly the kind of gap Binder exists to fill, because you don't need a full time lawyer to stay ready for disputes, you just need something watching for them and prepared when they arrive.
