Invoice and payment reminders function similarly to an alarm clock for your finances. They may sometimes irritate recipients, but they get you paid and keep your business running.

Sending invoices and payment reminders is critical in your company. It may not be the most fancy part of running a business, but it is essential to maintain a stable cash flow.

Despite the necessity of timely payments, many customers require a little encouragement to pay their bills on time. This is where invoice and payment reminders come in as a gentle reminder to ensure payments are completed on time.

Let’s get into the details.

What is an Invoice reminder?

An invoice reminder is a notice sent to a customer or client with an unpaid invoice past the due date.

A reminder usually includes the invoice number, amount owed, due date, and any relevant information such as incentives, late fees, or penalties.

Depending on the situation and the relationship between the business and the client, the tone of the reminder might range from warm and polite to firm and assertive.

Invoice reminders encourage your clients to settle their outstanding bills on time, which is essential for your business’s good cash flow and financial stability.

Reminders also contribute to customer trust and goodwill by communicating payment expectations in a straightforward and transparent manner.

Invoice and payment reminders are similar because they are communication tools your business uses to request payment for outstanding balances. However, there is a subtle difference between the two.

A payment reminder is sent after the invoice is due, while an invoice reminder is sent before or on the due date.

How To Write Invoice Reminders

Here are some tips for writing effective invoice reminders.

Be concise and clear

Include the invoice number, amount owed, and due date in the body of the reminder. Avoid using sophisticated words or legal jargon that may cause the receiver to become confused.

Be professional and polite

Maintain a professional tone while remaining polite and respectful in your messaging. Avoid accusing language and concluding about why the invoice has not been paid.

Offer payment alternatives

Make it simple for the recipient to pay the invoice by offering a variety of payment methods, such as online payment, bank transfer, or cheque. Include all required information for each payment option, including any applicable account or routing numbers.

Personalize the message

If possible, address the recipient by name and include any pertinent account or payment history information. This can help to establish a personal connection and boost the chances of receiving a timely response.

Consider offering incentives

To encourage quick payment, consider offering early payment reductions or waiving late fees for first-time late payers. Make sure that these incentives are adequately communicated in the reminder.

Follow up

If the invoice is overdue after the first reminder, send additional follow-up emails regularly. Adjust the message’s tone and urgency based on the recipient’s response or lack thereof.

How To Send Invoice Reminders

If you send reminders manually, you may set aside particular days to send invoice reminders based on the initial send and due date.

For example, you could set calendar notifications to send reminders a day or two after the due date.

Accounting software solutions do this automatically, saving you time and effort. On Akaunting, the invoice reminder works as a payment reminder.

What is a Payment Reminder?

You’ve completed the task, issued the invoice, and waited patiently for payment. However, the due date passes without indicating the money in your bank account. What are you going to do?

Do you make a phone call to the consumer and demand payment? Do you send a strong-worded email threatening legal action? Or do you give up and declare bankruptcy?

None of these alternatives seem particularly appealing, do they?

That is why you require a payment reminder: a friendly and professional approach to urge your consumer to pay what they owe you without ruining your customer relationship or wasting your time.
