Steps 1 and 2: overdue reminders

Step 1 a few days after the due date (professional or casual). Step 2 if there is no reply after a week or two (direct).

Subject line
Reminder: invoice #[NUMBER] was due [DATE]
Email body
Hi [Client Name],

A quick reminder that invoice #[NUMBER] for $[AMOUNT] was due on [DATE]. It may have been missed in a busy week, so here are the details again.

- Invoice number: [NUMBER]
- Amount due: $[AMOUNT]
- Original due date: [DATE]
- Days overdue: [X]

You can pay here: [Payment link]
Bank transfer details: [Bank details]

If you've already paid, thank you, and please ignore this. If something on the invoice is holding up payment, let me know and I'll help sort it out.

Thanks,
[Your Name]
[Your Company]

Step 3: final notice

Only after at least two reminders without a reply. State only consequences your contract allows and that you will carry out.

Subject line
Final notice: invoice #[NUMBER], payment due by [Date]
Email body
Hi [Client Name],

This is a final notice about invoice #[NUMBER] for $[AMOUNT]. It was due on [original due date] and is now [X] days overdue.

- Invoice number: [NUMBER]
- Original amount: $[AMOUNT]
- Late fee (only if your contract includes one): $[amount]
- Total due: $[total]

I sent reminders on [dates] and have not received payment or a reply.

Please pay by [final deadline] using one of these options:
- Card or bank payment: [Payment link]
- Bank transfer: [Bank details]

If payment is not received by [final deadline], I will [pause all work on your account / refer the balance to a collections agency / take the next step set out in our agreement].

If cash flow is the problem, please call or email me before that date and we can agree a payment plan. I would much rather settle this directly.

Regards,

Payment plan agreed

Send once the client agrees a plan, so the balance, dates, payment options and next steps are in writing.

Subject line
Payment plan for invoice #[NUMBER]: confirmed
Email body
Hi [Client Name],

Thanks for talking this through. Here is the payment plan we agreed for invoice #[NUMBER], so we both have it in writing.

[Only if your contract includes it: late fee of $[amount] included above / waived if the plan is kept]

Payments:
- $[amount] by [date]
- $[amount] by [date]
- $[amount] by [date]

How to pay: [Payment link] or bank transfer to [bank details]. Please use #[NUMBER] as the reference.

While the plan is on schedule: [work continues as normal / work resumes on (date)].
If a payment is missed: [what you agreed, e.g., "the remaining balance becomes due in full"].

When to use this template

Use these templates when an invoice passes its due date without payment. Many late invoices are not refusals. They are stuck in an approval queue, sent to the wrong person, or simply forgotten, and your first reminder should assume that. Late payment is common: Atradius' 2026 B2B payment practices survey found that late payments affect an average of 22% of B2B receivables in the US. A simple schedule suits many agencies: a friendly reminder 3 to 5 days after the due date, a firmer one at about 14 days, and a final notice at 30 days or later, once at least two reminders have gone unanswered. Match the schedule to your contract, and never mention a late fee, a work pause or collections unless your contract allows it. Writing these emails in advance has a second benefit. You will never send a reminder while annoyed, and every reminder will contain the same facts: invoice number, amount, original due date, days overdue and how to pay.

Best practices

Open with a check-in, not an accusation

"I wanted to check on invoice #1042" lands better than "Your payment is overdue." A polite email is more likely to be forwarded to the person who can actually pay it.

Restate the details every time

Include the invoice number, amount, original due date and days overdue in every reminder. Do not assume the client can find the original invoice. The aim is an email they can forward to accounts payable without adding anything.

Offer a way forward

If a client is short of cash, a payment plan or a part payment now is better than waiting for a full payment that may not come. A line like "If timing is the issue, I'm happy to agree a payment plan" opens that conversation.

Keep a record

Reminder emails also document your efforts to collect. If you ever need a collections agency or legal advice, dated and professional emails are your evidence, so keep the tone consistent from the first reminder to the last.

Quick tips

  • For large invoices, send a courtesy reminder a few days before the due date
  • Send the first overdue reminder 3 to 5 days after the due date
  • Assume an oversight first; you can always get firmer later
  • Include the payment link in every reminder
  • Escalate in steps: friendly, firm, then a final notice with a deadline
  • Only mention late fees or paused work if your contract includes them

What makes this template work

Escalates in stages

A friendly first reminder, a firmer second reminder and three final-notice versions, so you never write the hard one from scratch.

Assumes good faith first

The first reminder treats the late payment as an oversight, which keeps the conversation easy if that is what it was.

Restates every detail

Invoice number, amount, original due date and days overdue, so the email can be forwarded to accounts payable as it is.

Payment link in every version

Each reminder includes a payment link placeholder, so the client can pay from the email itself.

Room for a payment plan

Later versions offer a short payment plan, which gives a client who has gone quiet an easier way to reply.

A dated, factual record

Each email records what you asked for and when, which matters if you later need a collections agency.

Frequently asked questions

When should I send the first late payment reminder?

Three to five days after the due date is a reasonable first nudge. For large invoices, also send a courtesy reminder a few days before the due date, so the invoice is in the client's approval queue on time.

How often should I follow up on a late payment?

Roughly weekly for the first month is a sensible default: a reminder at 3 to 5 days, another at about 14 days, then a final notice around 30 days. If the final notice gets no reply, decide whether to pause work or use a collections agency, as your contract allows.

Can I charge late fees?

Only if your contract or terms of business include them, and only within what the law where you operate allows. If you do charge them, state the fee in the contract, on the invoice and in the reminder. Waiving a first late fee for a good client costs little and is often remembered.

When should I stop work for non-payment?

Only when your contract allows it, and only after saying so in writing: "Under our agreement, I'll need to pause work on [project] until the balance is paid." Set the trigger in the contract, for example 15 or 30 days overdue, so it is not a surprise.

Can AgencyPro send payment reminders automatically?

Yes. Payment reminders are part of invoicing on every AgencyPro plan. You turn on pre-due, due-date, overdue and final-notice reminders, set the timing and edit each email. Every reminder includes the invoice's payment link, and you can add a late fee after a grace period you choose.
