The water bill invoice is provided by a company that supplies water on a residential and/or commercial basis. A customer that receives their water supply from such a company will receive a water bill invoice complete with the charges for the company’s services and the amount owed for said services. From time to time, people forget to pay their utility bills, so the customer might see a summary of past due charges that must be paid on the next billing period. Payments not received on time could result in interest charges or additional fees. The water bill invoice will show the total amount due and the date upon which payment must be received.
