Nautlis ADline is our traffic scheduling/billing system, integrated into our sound file database.  The ads are scheduled into different blocks automatically according to the orders, avoiding commercials with the same topics running back to back. Invoices, and affidavits are printed from the sytem. The newest version also has a statistic section, wich creates weekly, monthly, and yearly  avails, or revenues. You can see your revenues by product group, agency, salesperson, or even customer. You can spot easily the under/oversold dayparts. A graphic chart will help you to compare todays values to the year before.  You can also check your accounts receivables, and bad debts.  All information then can be exported into EXCEL format.
