AA not Accounting

Hi List I wanted to use Freeradius as a AA (Authentication & Authorization) not much into Accounting. Just want it just as an "entry point" for outside engineers based on time limit. I have already test it with Freeradius and it works perfectly. Wanted to know if in your opinion it is a good strategy to use Freeradius as I want it to be or you would recommend some other tool.
