Reading Client Origin Maps Before a Second Office
Most professional firms already hold the geography of their practice in billing systems and intake forms. The gap is rarely missing data; it is reading that data as a map rather than a revenue table.
Begin with three full years of client or matter addresses, not the most recent twelve months. Seasonal work—tax peaks, construction permit cycles, clinical referral seasons—can inflate a single district for one year and vanish the next.
Cluster addresses by travel time to your current office, not by administrative boundary alone. A district that looks busy on paper may still be a long drive for partners who must appear in person.
When two districts show similar volume, look at who already refers work there: hospitals, builders, family offices, or municipal departments. A dense referral web often matters more than raw headcount of matters.
Only after the map is clear should you schedule field days. Walking the shortlisted streets with a partner who will cover the new office turns abstract heat maps into lease and staffing questions you can answer.
