Okay, I think I got this...

What I did was remove all of the extends and all of the Exporter stuff altogether. New code:

package Monro::CC;

use strict;
use warnings;

use Class::Accessor "antlers";

has 'transaction_type' => (
    is => 'rw',
);

And the script:

#!/usr/bin/perl

use strict;
use warnings;

use Monro::CC;

my $trans_obj = Monro::CC->new({
    'transaction_type' => $transaction_info[0],
});
