RE: FORMAL DEMAND FOR PAYMENT: Delinquent Invoice #HVAC-2026-104 ($3,850.00)

Dear Sir / Madam,

Despite multiple previous notices, Invoice #HVAC-2026-104 in the amount of $3,850.00 remains unpaid 30 days past the due date of 2026-09-15.

Under commercial prompt payment standards and statutory debt recovery legislation, we hereby notify you that late payment interest at the rate of 1.5% per month (18% per annum) along with statutory debt collection recovery administration fees have begun accruing on this account.

To avoid further escalation and continuous daily interest accruals, we demand full payment of the outstanding principal balance ($3,850.00) within seven (7) calendar days of the date of this letter.

Failure to remit payment will result in immediate escalation to formal third-party recovery proceedings.

Yours faithfully,
Receivables & Collections
