How to Set Up Automatic Invoice Reminders (And Stop Chasing Payments)

Anyone who has typed "just following up on my invoice" knows the particular drain of that sentence. You did the work, you sent the bill, and now you're the one doing unpaid labor to get paid for the paid labor. Automatic invoice reminders take that job off your desk. They're scheduled emails that go out for you before the due date, on it, and after it, so you never draft that awkward nudge by hand again. This walks through what they are, how to switch them on, and how to write ones that actually move money.

Why Invoices Go Unpaid (And Why Reminders Work)

Most late payments have nothing to do with bad faith. The invoice simply got buried. It landed on your client's desk during a busy Monday, got forwarded to accounting, and dropped out of everyone's mind. Three weeks later it's still sitting there because no one circled back. The fix isn't a prettier invoice, it's a reliable follow-up. Automatic reminders create steady touchpoints with zero effort from you, and the pattern is well documented: invoices that get scheduled reminders tend to clear noticeably faster than ones that get silence. Clients don't suddenly have more cash. The reminder just keeps your invoice on top of the pile instead of under it.

The 3-Reminder Sequence That Works

You don't need anything elaborate. Three reminders, well timed, handle the overwhelming majority of late payments.

Reminder 1: 3 Days Before the Due Date

Treat this as a courtesy, not a demand. You're giving the client room to get ahead of the deadline, so the tone stays warm and assumes they fully intend to pay.

Subject: Invoice #[Number] due in 3 days

Body: Hi [Name], a quick heads-up that invoice #[Number] for [Amount] is due on [Date]. You can view and pay it here: [payment link]. Let me know if you have any questions. Thanks!

Reminder 2: On the Due Date

A little more direct now, but still just stating a fact. The due date is today. Keep it tight and make the payment link impossible to miss.

Subject: Invoice #[Number] is due today

Body: Hi [Name], just a note that invoice #[Number] for [Amount] is due today. Pay online here: [payment link]. Reach out if you have any questions.

Reminder 3: 5-7 Days After the Due Date

This one names the situation plainly. It's still professional, but it makes clear you expect payment, and it's the place to reference your late fee policy if you have one.

Subject: Invoice #[Number], Overdue Notice

Body: Hi [Name], invoice #[Number] for [Amount] was due on [Date] and is now overdue. Please arrange payment at your earliest convenience: [payment link]. As a reminder, our terms include a 1.5% monthly fee on balances overdue by more than 15 days. Let me know if there's anything I can help resolve. Thanks.

What Happens If They Still Don't Pay?

If all three go out and the invoice is still sitting unpaid two weeks later, email has done its job and it's time to escalate. Call them. A short, professional phone call surfaces what email never will: either there's a real snag, like a wrong billing contact or a budget approval stuck in someone's queue, or you walk away with a firm date. If the call leads nowhere, your next moves are to pause new work, require a deposit on anything future, or push a high-value unpaid invoice toward collections. In practice you'll rarely get this far. Most invoices clear at the first or second reminder.

How to Set Up Automatic Reminders in WaffleInvoice

Turning reminders on in WaffleInvoice takes about two minutes. Open your Automation settings and enable payment reminders. Set the schedule, choosing how many days before and after the due date each one fires; 3 days before, on the due date, and 5 days after is a solid default. Then either customize the email templates to match how you write or leave the defaults as they are. From then on, every invoice you send follows up on its own schedule, and you never hand-write a payment reminder again.

Reminder Best Practices

A few things separate reminders that work from ones that get ignored. Always include the payment link, a direct clickable one in every single reminder, because the moment a client has to go hunting for how to pay, some of them just don't. Keep each message short; nobody enjoys reading a long email that's asking for money, so state the amount, drop the link, and get out. Don't apologize for following up either, because this is money you earned and a confident, professional tone consistently outperforms a sheepish one. Write a subject line that's scannable and exact, like "Invoice #047, Due Today," since vague subjects get skimmed past. And personalize where you can: the client's name and the specific invoice number make the email feel accountable rather than mass-blasted.

Late Fees: Should You Include Them?

Yes, and you should mention them in your reminders even if you have no intention of being heavy-handed about it. Simply stating that your terms carry a late fee creates accountability and shifts behavior, because a client who knows there's a cost to paying late tends to move your invoice up the list. The common rate is 1.5% per month on the outstanding balance. Put it in your original invoice terms, echo it in the overdue reminder, and if you ever do charge it, charge it the same way every time. Selective enforcement is how a policy quietly becomes a bluff.

The Bottom Line

Automatic invoice reminders are about the highest return you'll get for the lowest effort anywhere in your billing. They take minutes to set up, run forever without your attention, and pull down the average time it takes you to get paid. Stop drafting follow-up emails one at a time. Build the sequence once and let it handle the uncomfortable part. Create your free WaffleInvoice account and turn on automatic reminders today.
