A job starts by establishing what the finished file must be able to do. Categories are checked against the underlying description, not the label attached upstream. What arrives is a file whose every column has a written definition.

Franchise handling
Separating independently owned sites from company-owned ones where the evidence allows.
Tell us how you sell and we will show you how the audience divides.
