I have a tracking system that has sales tracking already put in but I need it to be made a little more simple. This project is simply cutting some code down and adding one small and quick feature...should take a matter of minutes for a decent programmer. The tracking currently has a "Is this a payperclick ad"? feature, want that simply deleted. And it tracks one time ads but tracks them every 30 days, I just want it to track it once, for example, they buy one email ad for $100...I want it to track all the clicks and sales for just that one ad, once, not every 30 days. The simple feature is this...the system currently gives users a code from the code generator in the form of an image tag that they put in their download page that tracks sales...I just simply need it to track only one sale per IP address so it doesn't record multiple sales for the same customer if they return. Ask questions on the message board. Programmer will be paid instantly via the scriptlance payment system upon project completion and offer another project.
