1. Start with the Tiffin firm you actually operate
Tiffin is a municipality in Johnson County, Iowa. The 2020–2024 ACS five-year estimate records 5,737 residents, with a margin of error of 18. That population figure describes the city; it does not establish legal demand, lead volume, competition or revenue. For custom software, its practical value is geographic clarity: your team can define whether the proposed tool is for work performed in Tiffin, matters handled across Johnson County, or a broader Iowa practice. Those are different operating scopes and should not be blended in a requirements conversation.
Recommended approach
Map the workflow by office responsibility and matter geography rather than beginning with the city name. Identify who handles an inquiry, who approves a referral, who updates a client, and which matters belong inside the first version. If your firm serves clients beyond Tiffin, decide whether the software should support that wider service area from the outset or begin with one repeatable internal process.
