So the client can find it without searching.

How to ask a client for payment politely
Asking to be paid isn’t rude. Being vague causes most of the awkwardness. A polite payment request is short, specific, and ends with an easy next step.
The basics
The 4 things every payment email needs
2. Amount
The exact amount due, in the invoice currency.
3. Due date
A real date, not “Net 30.”
4. How to pay
A payment link or clear instructions.
Leave out apologies like “sorry to bother you.” It’s routine business admin.
Copy-paste emails
What to say at each stage
Replace the bracketed parts. Asking for a date gets a concrete answer; “just following up” often gets none.
Before it’s due (3 days ahead)
Subject: Invoice #[123] due [Nov 3]
Hi [Name], a quick heads-up that invoice #[123] for $[amount] is due on [Nov 3]. You can pay here: [link]. Thanks!
On the due date
Hi [Name], just a reminder that invoice #[123] ($[amount]) is due today. Payment link: [link]. Thank you!
A few days late
Hi [Name], checking that invoice #[123] for $[amount] didn’t get buried. It was due [Nov 3]. Could you confirm the date it’s scheduled to be paid?
A week or more late
Hi [Name], invoice #[123] for $[amount] is now [7] days overdue. Please let me know by [date] when payment will be sent. If anything is holding it up on your side, I’m happy to help sort it out.
If you have an accounts payable contact, CC them. The person who approved the work often isn’t the person who pays.
Keep it polite and effective
Tips
Send on a schedule
Due date, +3, +7, +14 days — not when you’re frustrated.
Stay consistent
Keep the same amount and payment link in every message.
Mean every next step
Mention pausing work or a final notice only if you’ll really take that step.
Only mention late fees, interest, or collection steps if your written agreement includes them and they are lawful where you and your client are. Check local rules. This page is not legal advice and cannot guarantee payment.
