I have just brought clientexec and it seems great but i have a few questions.
i have setup all the packages etc, and created a client. this client used a coupon when purchasing the hosting a few months back (before setting up this billing system) for 20% discount for life.
i notice you can't have a 20% discount forever in the coupons, how can i do this?
i added a package manually to the client but how do i enter the coupon code to give the discount?
finally it doesn't have seem to have created a invoice when i setup the package, why?
