How can count the amount of traffic being sent from my site to client?

[Macbeth]

I'm being paid per click to drive traffic to another site, any ideas on how I can track the amount of clicks being sent to the client?
Also, How can I make sur they are not stitching me up by claiming i have sent less traffic than what is stated on my reports?

Do you have any scripting available (.php or .asp)? Do you have a database?

my webhost has php and mysql but nothing has been implemented on my website.

Well, if you have php and mysql then all you'd have to do is have a setup where all the links to the website you want to track are actually internal links like this: [yoursite.com...] where 21 is the id of an entry in the database. You set it up to open in a new window, do a database call to find out what link corresponds to id 21 and redirect to that URL. The page will also update a column in your database that corresponds to each link id number (e.g., "UPDATE links SET clicks = clicks+1 WHERE id=21).
