How do you manage your direct ad sales?

Hello,

i have a lot of direct bookings for ad campaigns and use DFP to deliver them - which is perfect for me.

Most of my direct ad-bookings are recurring on a monthly basis

To keep an overview on everything I use a spreadsheet with all the information inside.

Is there a (web)application available for this kind of thing? Where and how structured do you keep all this information?

Thanks
Tom

hm, no one deals with direct ad sales?
