Hi [Client Name],

I've noticed that Invoice #[NUMBER] for [AMOUNT] (due [DUE DATE]) remains unpaid, and I haven't heard back from you regarding previous reminders.

I understand that unexpected circumstances can affect cash flow, and I want to work with you to resolve this.

Payment Plan Option:
If paying the full amount at once is challenging, I can offer a payment plan:

• Total Amount: [AMOUNT]
• Payment Plan: 3 monthly installments of [INSTALLMENT AMOUNT]
• Installment 1: Due [DATE 1]
• Installment 2: Due [DATE 2]
• Installment 3: Due [DATE 3]

To accept this payment plan, please reply to this email by [DEADLINE] confirming your agreement. I'll send a payment plan agreement for signature.

Alternatively, if you can pay the full amount by [EARLIER DATE], I can waive the late fees.

Please let me know how you'd like to proceed. I'm here to help find a solution that works for both of us.
