[Serusers] billing question (some architectural case)

[Wojciech Ziniewicz]

Hello, 
I 've just came to the point of rolling my own billing that I have mysql
database with table "acc" and  details of called party , accstart, acc
period and so on. I have another table that I have prefixes and prices for
T1,T2,T3 . My question is : do You have some howtos, scripts for rating
users?

I try bash for now but it is slow and not scalable in future.. what about
mysql shell or sth? 
Could you send me some examples ?
I would appreciate that 

Regards.....
