8 Polite Invoice Payment Reminder Emails That Work

8 Polite Invoice Payment Reminder Emails That Work [Free Templates]

Sending overdue invoices via email is one of the tasks that most business owners dread. They want to focus on getting work done and getting more clients. Take a moment and imagine what will happen to your business if you neglect following up on invoices.

At first, everything feels fine. You have a bit of extra time during the workweek. You might push harder to get some work done or leave work early on Friday. You don’t have to confront your clients about their failure to pay.

As you continue to overlook unpaid invoices, the problems gradually pile up. Your cash flow falls 10% this month. Worse, clients may start to get out of the habit of paying your invoices on time. As more and more invoices continue to be paid late, your cash flow worsens. After a few months, you may have to draw on your savings or credit to pay the bills. If you have faced these problems, you’re far from alone because late invoice payments are a common problem.

1. Invoice Payment Statistics: What Does The Data Say?

Many businesses struggle to get their invoices paid correctly and on time. Industry research reveals that:

1.1. Many Freelancers Struggle With Late Payments

Research by Bonsai found that 29% of freelance invoices are paid late. Invoice payment delays are even worse with large dollar-value invoices. Fifty percent of Invoices over $10,000 are paid late.

1.2. 54% of companies expect late payment of invoices

There are also regional differences in late payments. In the USA, 71% of invoices are not paid on time and 46% of invoices are not paid on time in Canada. In comparison, businesses in Denmark report that 13% of invoices are not paid on time. Unfortunately, the COVID-19 pandemic has made late invoice payments more common. 

1.3. Few Invoices Take More Than 90 Days To Be Paid

In the UK, less than 4% of invoices take more than 90 days to be paid. Many businesses are taking longer to pay invoices. For example, German businesses have more than doubled (14 to 32 days) their invoice payment delays.

1.4. Invoice Fraud Is A Major Problem

Incorrect prices, fraud, and other unprofessional invoice behaviour are also key factors. One recent study found that Irish companies lost approximately  €14,000 to invoice fraud in 2022. As invoice fraud becomes more widespread, companies may implement more controls on payment. These increased safeguards may result in invoice payment delays, especially if there are manual reviews.

If you have suffered invoice payment delays, you are far from alone. One or two late invoices may not cause problems. What if late invoice payments become more common in your business?

2. What Happens When You Don’t Follow Up On Invoices?

You might struggle to pay your bills if you lack an emergency fund.

For most clients, receiving one or two reminders is enough to get them to send the payment. There are some cases when you need to take a different approach.

Instead, you will want to adapt these templates and think carefully about customizing them for your business.

6.1. Client Payment Method Challenges

Send this email to your primary contact (i.e., the VP of IT security in this example) to request assistance.

7. Frequently Asked Questions About Overdue Invoices

Invoice payment delays are a common problem in business. The templates provided above will give you an excellent starting point. However, you may still have a few questions. 

7.1. I have a lot of overdue invoices. How do I prevent this?

If the number of overdue invoices is increasing month over month, it is essential to understand what is causing this problem. Start by considering the following typical causes.

  • Insufficient upfront communication.

During the sales process, it is critically important to set your expectations. That includes covering when you expect invoices to be paid.

  • Poor client screening.

It’s sad that some people are disorganized or unethical and may not appreciate the importance of paying invoices on time. One way to decrease this problem is to ensure you are working with companies that have been in operation for a few years and have a steady cash flow. Alternatively, you may want to request upfront payment before starting work to ensure that your cash flow does not suffer.

  • You are not sending consistent invoice payment reminders

Use the invoice reminders in this guide as a starting point. In particular, sending reminders 7 days in advance of the due date and on the due date may be helpful.

7.2. How much should I charge for overdue invoice fees or penalties?

Charging late payment penalties when invoices are not paid on time is a common practice for many larger businesses. For a small business or freelancer, including a late payment penalty in your contracts is smart. If you are already having difficulties collecting an invoice payment, collecting a penalty may be difficult. In general, applying a 5% late payment penalty is reasonable (i.e. a $50 late payment penalty on a $1,000 invoice). 

7.3. Should I ever grant an exception to overdue invoice fees?

Granting exceptions to your payment terms should be rare and apply in unusual circumstances. For example, your client may have become ill and been away from work for several days. In this case, giving an exception to your late payment rules is reasonable. 

7.4. My cash flow is suffering due to multiple unpaid invoices. How do I handle this situation?

There are multiple ways to approach improving cash flow problems. Keep in mind that these solutions take some time to implement. If you have an emergency like paying rent tomorrow, take money out of your savings or use a loan.

  • Offer multiple invoice payment methods.

Relying exclusively on a single invoice payment method is unwise. You may prefer to use CheckYa but some of your clients may insist on using their preferred payment method. In these cases, it is worth persuading your client to change. If the client insists on using their preferred payment method, like a wire transfer, accept their preference and move on.

  • Use invoice payment reminders

Please choose at least two invoice payment reminder templates from this guide and add them to your business. Some people are simply disorganized and will take action when you give them a polite and friendly reminder.

  • Get more clients

Many business problems can be solved with more sales. Instead of constantly worrying about a few clients that pay invoices late, go out there and get more clients! To ensure you have a consistent flow of leads, set up a daily habit of working on sales. For example, you might set a habit goal to send 5-10 outreach emails to potential clients each week.

  • Review your business contracts

Read your business agreements to see what changes you need to make invoice payment easier. For example, have you clearly stated when the invoice is due for payment on the agreement and the invoice? Use our freelance contract templates as a starting point.

7.5. Is it worth hiring an assistant to help me with invoices?

Delegating invoice management to an assistant may be worthwhile in some circumstances. For example, you earn over $10,000 per month and have multiple overdue invoices each month. Hiring a part-time virtual assistant for $500-$1000 per month may make sense in this circumstance. 

Fortunately, you have other options. You can use CheckYa’s invoice dashboard. In a few seconds, you can easily find a breakdown of your invoices by paid, unpaid and overdue. That information makes it easy to follow up on late invoices. 

7.6. My client says they cannot use my preferred payment method. How do I respond?

Start by finding out why the client does not want to use your payment method. The answer could be a simple lack of knowledge or a matter of company policy. If possible, offer to set up a video conference call to provide a quick training guide on using CheckYa or your preferred payment option. If the client insists on using wire transfers, PayPal or another method, it’s best to stay flexible and accept their preference.

8. How To Complete Monthly Invoice Monitoring In 30 Minutes or Less

Monitoring your invoice status regularly is an important business discipline. Before implementing this process, ensure you have the right foundation. First, update your business agreements and invoice templates with crystal-clear payment instructions. Second, adapt this guide’s invoice payment reminder emails to your business. Now, you’re ready to start monitoring your invoices.

Once per month, schedule 30 minutes on your calendar to review your invoice activity. In particular, take note of any late invoice payments. During this monitoring time, look for trends. For example, if one client has been late paying your invoices several times over the past few months, you may want to take action. Start by setting up a call with the client to discuss your concerns and request improvement. If the client is not interested in improving, you may have to end that client relationship.
