A collection letter is a letter that a business will send to another business or a customer when there is an unpaid account or payments for an invoice are overdue. The point of the letter is to remind the debtor that their payments are late and give them an opportunity to settle the debt before more serious steps are taken.

If the first letter is unsuccessful, several collection letters may be sent before any legal action is taken.

When a collection agency is involved, the collection letter will be issued from the agency instead of being sent directly from the organization that is seeking compensation.

How to Write a Collection Letter:

1. Include all of the relevant details.

If you are in the position of having to write a collection letter, you need to include all of the details that are relevant to the party receiving the letter. This includes the exact sum of money owed, description of the service or goods provided at the time the transaction took place, what the original payment agreement was, etc. In other words, it needs to be abundantly clear that you upheld your end of the deal but the debtor failed to pay on time.

2. Be professional and courteous.

Do not include any emotional language or threatening phrases in your letter. The debtor is probably a customer whose business you would value in the future, so try to maintain a professional tone throughout the letter. If this is the first letter you have had to send, be extra cautious. For all you know, the missed payment could genuinely be a mistake.

3. Explain what the next steps are.

Tell the recipient of the letter what happens next, whether that means they have two weeks to pay without penalty, or whether it means you will send two more letters and begin to charge interest on their debt. Adding deadlines will help to make the situation more urgent and give the debtor an incentive to resolve the issue quickly.

4. Always keep copies of the letters and any response you receive.

Documenting your communication with the company or individual that owes you money could be important if they refuse or are unable to pay. In the unfortunate event that you need to take legal action, you can refer back to these letters and use them as evidence that you did everything you could to notify the debtor and resolve the issue.

Final Thoughts:

No one wants to be in the unfortunate position of having to send out a collection letter, but doing it the right way could help you to recover money that is owed to your business for good or services that you have already rendered.

While collection letters aren't always effective, in some cases they can solve your accounts receivable problems and help your business to get more cash flow.
