However I would suggest the use of a group system such as that found in YSI to separate the permissions, most admin systems are inclusive - the higher up admins have all the commands of the lower ones, if you were to use these systems all admins would have access to the "/flip" and "/count" commands, even though they may not have paid for them as players (though whether or not that's what you want is entirely up to you). The group system means you can easily and dynamically define exactly who can use what commands, so using your payment system you can simply add someone to the "flip users" group and from then on they have access to it (and, if you're using the YSI user system, this information may be saved automatically (depending on whether you use a named group or not)).
