billing issues

so last time I ran the billing script was  01/25/09.   I ran it last night, to reasonably good effect.  the problem is that it only creates one invoice at a time, so customers will see invoices the next three times I run freeside-daily.  ugh.   so the question is this:  do I run freeside-daily 3 times to get the pain over with at once?  do I credit people some or all of the months I didn't bill for?


just to explain, I haven't been running the thing nightly as I should because I had some problems with canceled customers getting spammed by the billing script. 

looks like I'm running it 3 times
