Why is there an invoice number field on the batch header?

The invoice number is provided by you and is necessary for you to trace your payment. This number should be numeric only. Do not enter alpha characters, spaces or dashes in the space provided. You may use all the spaces provided for your invoice number or you may use only one, but do not leave this field blank. Make sure your invoice number is unique for each batch header that you submit for payment. The invoice number(s) you enter on the Batch Header form will appear on the remittance advice of the State Treasurer's check you receive for the amount of the batch or batches you submitted for payment. For accuracy in crediting customers' accounts maintain a copy of each energy draft so when your payment is received you will be able to trace it back to the draft number that applies to the customer.
