The Day-Fifteen Reminder

How do I ask a customer for payment politely?

State what the invoice was for, the amount, the date it went out, and then ask one straightforward question: “Is this on your radar?”

The first reminder isn’t a confrontation. It assumes the customer simply hasn’t gotten to it yet — because on day fifteen, that’s usually what happened.

The message stays polite by staying factual and brief. What makes you sound rude isn’t the ask itself. It’s the three weeks of silence beforehand, which turns a routine follow-up into something that feels loaded for both of you.

What should a past due invoice email say?

By day thirty, it should clearly state that the invoice is now past due, restate the amount and original date, and ask for a specific date when payment will arrive.

Not whether they’ll pay. When.

Asking for a date is the key move here: it gives them something concrete to respond to and gives you something concrete to follow up on.

Don’t apologize for asking, and don’t explain why you need the money. The terms are the reason.

When should I send a payment reminder?

On a schedule you set before the invoice went out — not on the day you finally get annoyed enough to say something.

Day 15, day 30, and day 45 works for most small businesses on net-30 terms: one nudge before it’s late, one when it’s late, and one that states what happens next.

The specific dates matter less than having dates at all. A reminder that goes out because the calendar says so is easy to send. A reminder that goes out because you’ve been stewing about it for a month is the one that comes out wrong.

How do I ask for payment professionally in a text message?

The same way you would in an email, just with less of it.

No subject line. No opening pleasantries. No formal sign-off. Just the job, the amount, the date, and the question.

A text reminder should read like something you typed between jobs — because that’s what it is. If you normally text this customer, they’ll find a formal email stranger than a direct message.

Tell the tool that’s how you reach them, and it’ll write the text-length versions.

What if my invoice didn’t have payment terms on it?

Then day fifteen is your number, not theirs.

You can still send the reminders, and you should. But the real fix is on the next invoice, not this one.

One sentence does it: “Payment is due within 15 days of the invoice date.”

Print it on every invoice from now on. It’s the difference between chasing a customer and reminding them of something they already agreed to.

Is this payment reminder generator free?

Yes. It doesn’t ask for your email and stores nothing.

You give it the customer’s name, the job, the amount and date, your terms, how you reach them, and how you normally talk to them. It returns three messages in your voice, plus a short note on what to adjust if one of them doesn’t sound quite right.

Nothing you type is stored or sent anywhere except to generate your messages.
