You probably didn't notice any problems in the simplest case, but, no,
this actually doesn't doesn't work very well at all.

For starters I'd say you probably want to start with $cust_bill->owed
rather than $cust_main->balance_date().  You'll be charging a lot of
duplicate late fees for a lot of old balances doing it like that.

Secondly (though this is a moot point if you use $cust_bill->owed),
"time-10" is not a number of days.  "time" returns the current time in
seconds since the epoch.  See "perldoc -f time".  Subtracting ten backs
up 10 seconds, and multiplying by 86400 (the number of seconds in a day)
results in an absurdly large number.  When considered as a date, this
means some far-off future date, and thus ->balance_date() with this huge
number only considers invoices before the far-off future date,
and so behaves just like ->balance().


  $cust_bill->owed * 0.05
