Free Sub-Affiliate Tracking Website/Program

I have several sub-affiliates that are promoting offers and I am looking for an easy free program that will allow them see their own statistics (clicks and leads) for their unique tracking link. I am a Maxbounty affiliate and use sub-ID's to generate unique tracking links for each affiliate. I am able to see click and lead information of my end through the Sub-ID Report, however my sub-affiliates cannot see this information. I know that my sub-affiliates would like to see this information for themselves instead of just taking my word to pay them upon sale. Does anyone have recommendations for a free simple website/manager that will display click and lead information for their tracking links? Thanks a lot!

I've not heard of a free solution but there area cheaper solutions. Something like post affiliate pro. We offer our own solution for this for free but its only for our affiliates with sub affiliates who want to see their own stats but its not a solution we sell. I would say if they are making you money, bite the bullet and buy a cheap solution (providing they only need basic stats).
