Deposit Verification products

We have many stores, mostly in small towns, and are looking for a way to 
validate that what the store tells us was deposited to the bank at the end 
of the day and what the banks says was deposited are the same.  We have a 
file that contains what the store says they deposited but, since the stores 
are in small towns, we need a way to collect the information from each bank.

We are currently receiving what's known as a BAI file from our 10 largest 
banks, which accounts for approximately 1/3 of our stores.  What we are 
looking for is a vendor that can take those 10 banks plus the other 200 or 
so banks that we deal with and generate one file containing all of the 
information from each store.  Is there anyone out there with multiple 
locations, using multiple banks that consolidates their bank information 
into one file?  What software or vendor do you use?

TIA,

Steve
