Five Great Collection Letter Templates For Your Law Firm

When sending collection letters, it’s always important to have a variety of letters on hand for the different stages of the process. With each notification, it’s important to convey the right balance of courtesy and urgency that befits the situation. After all, it would be off-putting for the client to receive a “demand for immediate payment” with their very first bill. At the same time, keeping a friendly, upbeat tone with the sixth notice would fail to convey how serious the matter has become.

Here are some collection letters to keep on hand. These will take you through every phase of the collection process, from the first invoice to receipt of payment.

First reminder: Payment due

As soon as the client matter is closed and the charges are assessed the client should receive the invoice right away.

At this phase, use friendly language and personal touches such as the name of the client in the greeting. At the same time, keep the overall message brief, straightforward, and provide specifics when possible. Instead of saying, “Payment is due in 21 days,” a specific due date is much stronger.

Subject line: Invoice No. 1234 from Downtown Law Firm

Second reminder: Payment due

When it comes to accounts receivable, more reminders are always better. Because people lose track of emails, a single notice may not suffice. Luckily, email costs nothing to send, so send the extra notification. Seven days before the payment is due, send a reminder along with another that arrives on the due date itself. 

Subject line: Follow-up No. 1234 from Downtown Law Firm

Dear [client name],

Third reminder: Payment is overdue

If the due date comes and goes without payment, it can be difficult to ask for the money. But sending reminders is key to getting paid.

Once the account is seven days past due, make contact by phone before sending another past-due notice. This is an opportunity to inquire whether the invoices have been received and to get a verbal commitment from the client for the next step. If it’s appropriate, you can set up a payment plan with them. Before the call ends, inform them that they can expect an additional notice and send it immediately after hanging up. This will give them access to the payment portal and invoice while the matter is fresh in their minds. At this point, you’ll want to raise the level of urgency in the language. 

Subject line: Payment Needed: Invoice No. 1234 for Downtown Law Firm

Dear [client name],

Please review your invoice, which is provided through this link, and make a credit card payment. Otherwise, please contact our office this week to let us know the status of this payment. 

Fourth reminder: Final notice email

Once the account reaches 45 days past due, it’s time to make the language of the email more urgent. Keep the language courteous but convey to the client that if payment doesn’t arrive by a certain date, a specific action will be taken.

Along with sending these notices, attempt contact with another individual in the organization with a phone call, mailed letter, and email. For emphasis and clarity, use bold text on the invoice number, amount, and due date.

Final communication: Payment received

When your clients make a credit card payment, send a brief email. This assures them the payment was received while making a great impression.

The key to getting paid is sending notices and reminders frequently. It may seem like overkill, especially if you’re accustomed to the cadence of mailed notices, but given the volume of emails that land in someone’s inbox every day, an emailed notice can be easily overlooked or forgotten. Sending repeated emails keeps payment in front of your client and your firm in front of your cash flow.
