There are two things to keep in mind when considering stacking.
#1: Is it prohibited in the agreement with the funding company who is in first position?
#2: Will it help or hurt the merchant and funding company in first position? A good underwriter will make sure that the total $ amount being paid out per month by the merchant after getting the stacked advance will be a number that the merchant can withstand (taking into consideration the SIC and profit margins for that industry).

By not carefully reviewing these 2 things you not only hurt the merchant and the funding company in first position. You also risk a default.

This is assuming:

1) the "underwriter" (and I use the term loosely) needs to be willing to do the math involved to figure out the margins
2) the ISO or rep involved gives a rat's ass about the merchant
