The Overdue Payment Letter is a crucial document in Dutch business operations, used when payment for goods or services remains outstanding beyond the agreed-upon terms. It serves as a formal demand for payment and, importantly, constitutes a legal notice of default (ingebrekestelling) under Dutch law. This document becomes necessary when initial invoices and friendly payment reminders have been unsuccessful. It must comply with specific requirements of the Dutch Civil Code, particularly regarding statutory interest rates and collection costs. The letter typically follows after the payment term has expired and precedes more severe legal actions such as debt collection proceedings. It should include precise details about the outstanding amount, original invoice(s), applicable interest rates, and a reasonable deadline for payment. This document is particularly important as it establishes a formal record of attempted collection and serves as a prerequisite for any subsequent legal action under Dutch law.
