1. Start with the Mattoon service area, not a generic software brief
Mattoon is recorded as a municipality in Coles County, Illinois. The 2020–2024 American Community Survey 5-year estimate records 16,586 residents, with a margin of error of 410. That geographic fact helps define the service area for a Mattoon-focused firm, but it does not establish legal demand, case volume, competition or revenue. For custom software, its practical use is narrower: it can help you state which office, service area or intake team the workflow must support. If your firm serves clients beyond Mattoon, identify those additional locations separately rather than treating the city and county as interchangeable.
Recommended approach
On the call, describe the users and geography the tool must serve. Decide whether the first build is for one Mattoon office workflow, a Coles County process or a broader Illinois operation. Keep that boundary explicit so the proposed tool does not quietly expand into an undefined platform.
