What is a past due notice?
A past due notice is a formal letter reminding a customer that an invoice is overdue. It restates the original amount, adds any late fees or interest owed, and sets a clear deadline for payment before further action.
How to write a late payment letter
Reference the original invoice number and date, state the outstanding balance and any accrued interest, give a specific payment deadline, and keep the tone firm but professional. This generator formats all of it automatically.
Why send past due notices?
A documented reminder trail speeds up collections and is often required before pursuing legal remedies or engaging a collection agency. Consistent notices with clear interest terms also encourage customers to pay on time in the future.
