High volume recharge operations should consider recording their internal sales transactions through a computerized billing system and an automated feed to FAS in place of Comptroller Form 62. Interested operations should contact the Comptroller's Office, Data Control Group, to obtain the appropriate format for an automated feed of data to the financial accounting system. Smaller recharge operations should use the Interdepartmental Order Forms (Form 62) to record their internal sales. In both situations this information must be submitted at least once each month to the Comptroller's Office.
