1. Follow up at the Right Time

Here are some tips to follow up at the right time:

• Follow up the day after an invoice is due, especially if the client regularly pays late
• Follow up after a week or two if the client’s usually on time with payment or they’re a new client
• Follow up again at 30, 60 and 90 days after the due date
• Try sending an overdue invoice letter on the weekend when your invoice has less competition for the client’s attention
• Tuesdays are the best day to email during the week, says to Entrepreneur. Try sending right before or after lunch.
• If you have multiple customers with overdue accounts, send all your reminders at once to save time

2. Include All Invoice and Payment Details

Make it easy for the customer to remember what invoice they need to pay and how to make the payment.

Include the following details in your overdue invoice letter:

• Invoice number and date
• Amount owing
• Payment terms such as late fees
• Reminders of previous letters
• Instructions for payment (include links in emails)
• Your contact information

3. Tailor the Language

The overdue invoice letter you send the day after an invoice is due definitely won’t be the same as the one you send 60 days past due. You need to tailor your language according to the situation.

Payment reminder letter templates can be found below.

1-15 Days Past Due

Be friendly and polite. Your aim is to maintain your relationship with your customer while also gently reminding them of their debt.

30-60 Days Past Due

Stay professional but be firm and demonstrate the urgency of paying the invoice. At this point, the invoice is very overdue and you shouldn’t be afraid to say so.

90+ Days Past Due

The longer a client doesn’t pay an invoice, the less likely they’ll pay at all. After 90 days, it’s time to turn the invoice over to a collection agency.

An overdue invoice letter in this case will serve to notify the client that you will turn over their account to a collection agency in a certain number of days if you don’t receive payment. Or if you still don’t receive payment, let the client know that the collection agency will be in touch.

4. Use Late Penalties

Late fees must be discussed with a client at the outset of a project. A client can’t be ambushed with late fees after an invoice is overdue. This will only sour your relationship.

Late fees can be a set amount or a percentage of the invoice total. Each state has its own laws regarding how much you can charge.

• For example, if a state lets you charge 18 percent interest, divide that number by 12 to find the late fee you can charge monthly. At 18 percent, a business can charge 1.5 percent of the invoice total in late fees on a monthly basis.

Not every business should charge late fees. This FreshBooks blog post covers the pros and cons of charging your clients late fees.

5. Offer a Payment Plan

Entrepreneur recommends offering your client a payment plan if mounting late fees don’t seem to faze them. Divide the invoice total up into manageable chunks. It’s not ideal, but at least you’re increasing the likelihood of getting paid.

6. Be Polite

Being polite in your overdue invoice letter isn’t just a courtesy. It can also actually help you get paid. FreshBooks found that invoices that included phrases like “please pay your invoice within” and “thank you for your business” were actually 5 percent more likely to be paid.

Be sure to include “please” and “thank you” in your letter even when the invoice is months overdue. At the very least, it improves the image of your company.

7. Automate Reminders

Invoicing software often includes the option to automate reminders to request payment. You can set when you want a reminder to be sent—after one day, 30 days, 60 days, whatever you want—and a personal message with each. This way you don’t have to set reminders in your calendar and email the client on each date.

Invoicing software can also automatically add late fees to the invoice total, as long as you’ve discussed your late fee policy with your client in advance.

8. Enlist Help

Sometimes, despite your patient and professional follow up letters, a client simply has no intention of paying their invoice.

If the invoice is sizable, it could be time to bring a collection agency or lawyer on board to help collect the debt. Use the Better Business Bureau’s website to find a reputable collection agency.

Send a second-to-last overdue invoice letter citing your intention to turn the invoice over to an attorney or agency.

In the final letter, notify them that your legal counsel or collection agency will be in touch. You must send the client a final warning letter to give them a last opportunity to pay before you hand over the unpaid bill.

How to Write a Past Due Invoice Letter

Here are some tips to write an effective and professional past due invoice letter:

• For invoices that are only slightly overdue, add the phrase “for your convenience.” A day after an invoice is due, you can write: For your convenience, I’m sending a quick reminder about invoice #001 that was due yesterday.
• Attach the invoice and add links to easy online payment options
• Try polite phrases such as “your account now appears to be overdue”
• Remind the client of previous discussions. You can say: As you know, invoices are due 15 days after the invoice date. This reminds the client of your original discussion about payment terms.
• Don’t forget to use strong (but still professional) language for invoices that are over 60 days due. Phrases like “urgent matter” or “immediate attention” will convey the seriousness of the situation. Your subject line can include phrases like “Action Required” or “Important.”
• Be direct. Include in the first line of your letter: We would like to inform you that your invoice is now 60 days overdue.
• Remind the client you will call them via phone to follow up. This may jolt them into action.
