1. Start with the Reserve service area, not a generic software brief
Reserve is recorded by the U.S. Census Bureau as a census-designated place in St. John the Baptist Parish. Its 2020–2024 ACS five-year population estimate is 7,791, with a margin of error of 978. That figure describes the place and does not establish legal demand, search volume, competition, case volume or revenue. It does, however, give your firm a precise geographic frame for the first conversation: which people, matters or referral relationships does the proposed tool serve, and does its scope extend beyond Reserve into the rest of St. John the Baptist Parish or elsewhere in Louisiana?
Recommended approach
Write the service boundary into the brief. Then separate local intake, parish-wide work and any broader Louisiana workflow instead of treating them as one audience. That distinction can affect fields, routing rules, access permissions and reporting questions.
