My name is Igor, I’m one of the developers of AdMaster traffic software.
We are currently working on a browser-based billing and invoicing tool, which will soon be available free of charge to everyone. It will search your broadcast logs for the broadcasted spots, and create the invoices based on your advertising rate card and other parameters.
To make sure that we’ve covered as many invoicing options as possible, we would be grateful if you would send us a sample invoice that you send to your customers, and a sample broadcast log created by mAirList.
All the comments are welcome, and the address is support@admaster info. For more information on our traffic software, please visit www.admaster.info
