Your invoice reminders are chasing people who already paid you
If your customers pay by Interac e-Transfer, no Canadian invoicing tool marks the invoice paid. The reminders keep firing at people who settled last week.

Once a week, open your bank's deposit list and your unpaid-invoice list side by side and match them before the reminder schedule runs. If that takes more than fifteen minutes, automate the matching — not the reminders.
This is the most common way an automated invoicing setup quietly stops working, and almost nobody names it out loud.
You turned on automatic reminders. Good. Then a customer paid you by e-Transfer, because in Alberta that is simply how a lot of people pay. The money is in your bank account. Your invoicing software has no idea. The invoice is still open, so on day three the reminder goes out, and your customer — who paid you on Tuesday — gets an email implying they did not.
Why no tool fixes this for you
Card and EFT payments carry a reference the processor hands back to your software, so the invoice closes itself. Interac e-Transfer does not work that way. It arrives as a deposit in your bank with a sender name and, if you are lucky, a memo line. There is no invoice number in the payload, so there is nothing for the software to match against.
Wave, FreshBooks and QuickBooks all handle e-transfers the same way: they do not. You mark it paid by hand or it stays open forever.
The fifteen-minute version you can do today
- Pick one slot a week — Monday morning is best, because it lands before most reminder schedules fire.
- Open your bank's deposit list for the last seven days and your invoicing tool's unpaid list.
- Match by amount first, sender name second. Amount alone resolves most of them.
- Mark them paid before you do anything else that morning.
Two things make this dramatically faster: ask customers to put the invoice number in the e-Transfer message field (most will, if you put the line right next to the amount on the invoice), and use amounts that do not collide — if three invoices are all exactly $500, you are going to guess.
Set the reminders so a miss is not embarrassing
Even with a weekly match, something will slip. Write the reminder so it survives being wrong:
✗ Costs you a customer
“Your payment is overdue.”
✓ Survives being wrong
“Our records show invoice 1042 as unpaid — if you have already sent it, ignore this and thank you.”
One sentence, and a wrongly-sent reminder stops costing you a relationship.
When it is worth automating
Do the arithmetic before you buy anything. Fifteen minutes a week is thirteen hours a year. If you are matching thirty or forty deposits a week rather than five, the weekly slot becomes an hour, the slips become constant, and the fix is a rule that reads the deposit notification, pulls the amount and sender, finds the one open invoice that matches, and marks it paid.
That is a small piece of software, not a platform. We run one on our own billing inbox because we had exactly this problem.
