Hi. I am trying to use the Networkdays formula in ColF but need to have the
formula check the Billing Start, Billing End, FreeTrail Start, FreeTrail End
dates to determine the # of billing days. For example, for Product AN, since
the free trail starts after the billing start date and ends before the
billing end date the formula in ColF needs to count the business days between
12/1-12/6 (4) and 12/15-12/31 (13).

Thank you in advance.

Hi
if B1 contains the billing start and B2 the billing end try in F4 (note: in
your example you seem to exclude the start and end date of the free trail
duration)
=NETWORKDAYS($B$1,$B$2)-IF(COUNT(D4:E4),NETWORKDAYS(MAX($B$1,D4)+1,MIN($B$ 2,E4)-1),0)

But not totally sure what should happen for all cases of your trial period.
But this should give you something to start with
