I tried the first example and it only printed the customer name with a count of 0.
open(FILE, "data.txt");
open(FILE2, "info.csv");

@data = <FILE>;
@data2 = <FILE2>;

## TEST CODE

foreach (@data) {
        ($id,$name,$ref) = split( /,/, $_);
        print "The customer is $name";

        $no = grep { m/,$id$/ } @data2;

        print "We have $no docs by this $id\n";

}

close(FILE);
close(FILE2);

exit;
## END TEST CODE

Am I not thinking clearly(as I usually don't) on this or what?
Here's the output:
he customer is Customer1 coWe have 0 docs by this 1
The customer is Customer2 coWe have 0 docs by this 2
The customer is Customer3 coWe have 0 docs by this 3
