Solution: A residential-focused payment-protection and lien tool: (1) Deadline engine — by state and job, tracks the windows for preliminary/intent notices and mechanic's-lien filing so the contractor never loses lien rights by missing a date; (2) Document generator — produces the correct preliminary notice, notice of intent to lien, and mechanic's lien for the job's state, pre-filled from job data; (3) Escalation ladder — guided steps from friendly reminder → past-due notice → notice of intent → lien filing, with proven templates at each stage; (4) Homeowner-friendly framing — keeps tone professional to preserve reviews/relationships while still protecting rights; (5) Filing assistance — connects to county recording/filing where needed; (6) Payment tracking and automated reminders integrated with invoicing. ICP: Solo and small residential trade contractors who do the work, send an invoice, and then chase the money — sometimes for months. They rarely send preliminary notices, don't know their state's mechanic's-lien deadlines, and treat a non-paying homeowner as a write-off because filing a lien feels too complex and lawyer-dependent.

Residential-trade focus and simplicity is the differentiator — Levelset's commercial complexity is overkill and intimidating for a solo plumber, while invoicing tools ignore lien rights entirely. The state-specific deadline engine plus the guided escalation ladder (where the notice of intent frequently triggers payment without an actual filing) deliver the get-paid outcome without requiring a lawyer.

“Similar to how Levelset itself proved the model for commercial lien management — this is the residential, simplified, solo-operator version of that proven category, the way consumer tax tools simplified what was once accountant-only work. The category is validated; the underserved segment is the opening.”
