Start with the workflow, not the feature list
Bosseo describes Custom Software as a way to build around how a firm works rather than forcing the firm into a generic legal SaaS workflow. The public service page gives examples including client portals, intake tools, internal dashboards, referral trackers and tools that connect existing systems. For a Tukwila firm, the relevant local decision is operational, not demographic: identify which process is actually used by the office serving clients in Tukwila and King County, then document where that process stalls. A population estimate for Tukwila cannot tell you which workflow is expensive or unsuitable. Your own process record must do that.
Recommended approach
Describe the bottleneck in plain language. Note who performs each step, what information is entered, where it is stored, which permissions are needed and what a successful result looks like. If an existing product already handles the requirement adequately, compare that option before commissioning a custom build.
