How to remind a client before the invoice falls due
A payment reminder email template is a pre-written message you send before an invoice falls due — the single most effective step to get paid on time without damaging the relationship. A reminder that arrives three days before the due date reads as helpful admin; the same message sent ten days after the due date reads as a complaint.
This page covers the before-due-date stage of the chasing cycle. Work through the tone ladder above: start friendly for every client, go firm when the due date is close and the amount is significant, and use urgent only when a missed payment would hurt your own obligations. Most invoices never need more than the friendly one.
Send the reminder one to three business days before the due date, early in the recipient’s morning. Quote the invoice number, the amount and the exact date it is due — the easier you make it for accounts payable to match your email to their system, the faster you get paid. Always include the payment link or your payment details, so the next click is the payment itself.
If the due date passes without the money arriving, don’t repeat this reminder — escalate. Move to the seven-day overdue reminder, then the thirty-day final notice. A dated ladder of polite, increasingly firm messages is what collections advice recommends, and each template on this site covers one rung of that ladder.
What to include in a before-due payment reminder
- The invoice number and amount — accounts payable matches on these two fields first.
- The exact due date, written out ("Friday, 14 March") so it can’t be skimmed past.
- A payment link or your bank details, so paying takes one click from the email.
- An offer to resend the invoice — "lost it" is the most common honest reason for silence.
- Your name and a direct way to reach you, in case their process needs a PO number or approval first.
Keep the sequence going: 7-day overdue reminder, second payment reminder, 30-day final notice.
Frequently asked questions
When should I send a payment reminder before the due date?
One to three business days before the invoice is due. It lands while the payment is still on your client’s to-do list and reads as a helpful nudge rather than a chase. For very large invoices, a first heads-up a week out is also fine.
How do you write a polite payment reminder email?
Open with the invoice number and due date, assume the delay is an oversight, and end with the payment link. One short paragraph is enough — the friendly template above is four sentences. Politeness comes from being specific and unhurried, not from adding apologies.
Is it rude to remind a client about a payment?
Not before the due date — it’s standard practice and most accounting teams expect it. It gets awkward only when reminders are vague, frequent or accusatory. Quote the facts (invoice, amount, date) and keep the tone neutral, and a reminder reads as professional admin.
What subject line should a payment reminder use?
Put the invoice number and the due date in the subject, like "Friendly reminder: Invoice #1042 is due on 14 March". The client can triage it in one glance, and it won’t be mistaken for the overdue chase that might follow.
What if the client still doesn’t pay after the due date?
Escalate on a schedule instead of repeating the same message: a seven-day overdue reminder, then a thirty-day final notice that states what happens next. Each stage has its own template on this site, and a dated ladder keeps you polite while making the consequences clear.
When to send this reminder
- Send 3–7 days before the due date for a high-value invoice.
- Keep it short — one clear ask, no guilt-trip.
- Add a payment link if you can, so paying takes one click.
