Hi,

If you use a third billing system like clickbank, 2checkout or ibil, how do you charge for extra charges?

Assume that you have package A which costs $10/month and has 2 GB bandwidth/month. If the client used more than 2GB in a certain month, how do you charge him/her for that?

I believe that all of those billing systems make you use a fixed price, and you can't change that for a certian customer..correct? then, how do you do it?

Also, what if I want to increase the charge for a certain client? how can you do it through those billing systems?

I'd really appreciate your help.

Thank you,
Ahmed

I would say the best way is make a bunch of extra packages, such as: 1 gig, 2 gig, 3 gig, etc. Then set them not to recourr. Then if a client goes over, send them a link to pay for it. Also for extra emails, you could do the same thing, just have it recourring.

Thanks David, that really helps!

Best Regards,
Ahmed
