Are you dealing with unpaid invoices from your clients? If your client hasn’t been paying within a set period, sending a late payment email may get the results you need.

However, making sure your reminder email remains courteous while asking for funds is crucial to making payment collection easier.

One of the best writing strategies for this type of email is to display professionalism and ask clients for late payments with a respectful tone.

In this blog post, we will share tips on writing a polite late payment email to help you get paid and maintain a positive relationship with your clients.

Don’t be afraid about sending late payment emails

Late payments are among the most challenging problems many businesses face today, with as many as 87% of companies paying late. 

Small or large, these late payments can harm small businesses and solo freelancers who need to maintain a steady cash flow. 

Chasing late payments can be an uncomfortable and awkward experience, causing many to feel hesitant or even embarrassed about pursuing what is rightfully owed to them. 

But it’s important to remember that late payments can significantly impact your financial health and that you have every right to follow up on unpaid invoices. 

By being assertive and persistent in pursuing payment, you demonstrate the value of your work and send a message that you expect to be treated professionally and fairly. 

So don’t be shy about chasing late payments — it’s a necessary part of doing business and essential for maintaining financial stability.

Besides, holding your clients accountable is just as important, and often these payment issues are a matter of communication. 

Many clients miss payments simply because they forget about a due date or lose an invoice, and it can all be easily solved with a polite email reminder.

6 tips for writing a polite but firm late payment email

1. Use a clear and direct email subject line

When sending an email for late payments, you want to be simple and take a no-nonsense approach. 

For example, be direct and mention the invoice in the subject line, as this can immediately catch the client’s attention and remind them about the missed payment. 

So include your company name or invoice number to provide additional context for the email. Here are some example subject lines you can refer to 

• Attn: Late payment for Invoice #345 
• Hicom Tech: Your Invoice #5487 is One Week Overdue
• Payment for Invoice #1388 Overdue Notice

2. Start with a friendly opening or greeting

It can be worrying and frustrating to know that your work is not paid, but it is essential to maintain proper email etiquette. 

Start the email with a polite greeting, and remember that you want to ask for payment while still maintaining the possibility of future opportunities with clients.

In the beginning, you can just send a soft reminder like: 

This statement acknowledges that the payment has yet to be received and will help set a friendly tone for the rest of the email.

3. Attach invoice or payment details

When sending out your reminder email, providing details like the unpaid invoice number, the amount owed, and the new due date can be helpful. 

Attaching the invoice or payment link can help clients make quick payments and understand the urgency of the situation.

4. Follow up and note the consequences of late payment

If you are still not receiving a response after sending the initial email, don’t be afraid to send a follow-up reminder. 

The best follow-up time is three days to one week after your first email. At this point, be clear to the client that you are firm about settling the payment. 

If that doesn’t work, send another reminder in two weeks, then one month later. 

While you should be polite, avoid beating around the bush. Be direct and note that the invoice email is the final warning. 

It is also worth noting that if an invoice is overdue by more than 30 days, you may have the legal right to add late payment interest to the outstanding amount. 

Otherwise, include a final cut-off date and outline the consequences of non-payment. Because simply reminding the client of this can motivate them to pay.

5. Offer alternative payment solutions

Sometimes, all your client needs is flexibility. If the client is experiencing financial difficulties, offering payment plans or alternative payment methods can help them meet their obligations.

You can specifically draw their attention to these options by suggesting them: 

6. Show gratitude and end on a positive note

Once the payment is made, close the email on a positive note by thanking the client for their attention and expressing your appreciation for their business. 

You can also emphasize the importance of timely payment. Politely and professionally, explain why it is essential for you to receive payment on time. 

How to prevent late payments in the future?

At last, polite late payment emails are only band-aid solutions. To avoid late payments from happening again in the future, you need to communicate properly with your client.

Draft an agreement and establish clear payment terms, including due dates and consequences for late payment. Make sure this info is clear to clients before any work is delivered. 

Another strategy to consider is offering incentives for advance payments, such as discounts or rewards, to encourage clients to pay on time or before schedule.

Still, you will likely meet clients who need to pay on time.  

Creating a schedule for unpaid invoice reminders can make it easier to chase invoices. You can use invoicing and payment collection services like InvoiceBerry, or do it manually. 

Either way, preparing an email schedule and relevant email messages can make payments more manageable. 

Here are some effective professional email samples using copywriting basics to help you request payment without affecting client relationships.
