Construction payment rights and lien management software acquired by Procore; automates mechanics liens, preliminary notices, and lien waivers across all 50 US states, protecting contractors and subcontractors from non-payment in complex projects.
About
Levelset is a New Orleans-based construction payment software company acquired by Procore in 2021, providing mechanics lien management, preliminary notice automation, and payment rights protection tools for contractors, subcontractors, and suppliers in the construction industry. Founded in 2012 as zlien, the company built its product around the insight that lien rights—the legal tools that protect construction participants from non-payment—are chronically underutilized because the process of preserving them is complex, jurisdiction-specific, and deadline-driven. Levelset automates the preparation and delivery of preliminary notices, lien waivers, and mechanics liens across all 50 U.S. states, handling the jurisdictional variation that makes manual compliance extremely difficult for contractors working across multiple states.\n\nLevelset's platform covers the full payment cycle risk management workflow: from preliminary notice delivery at the start of a project through payment status tracking, lien waiver exchange, and mechanics lien filing when payments are disputed or delayed. The company also built a credit risk layer that provides payment history and credit data on general contractors and property owners, helping subcontractors assess payment risk before accepting project work. This financial intelligence capability, combined with payment rights automation, positions Levelset as a cash flow protection tool for the construction supply chain—a segment chronically affected by slow payment and project payment disputes.\n\nSince the Procore acquisition, Levelset has been integrated into the Procore construction management platform, enabling Procore users to access payment rights and lien management tools directly within their existing project management workflow. The combined offering strengthens Procore's value proposition for subcontractors, who have historically been less well served by construction project management platforms focused primarily on GC workflows. Levelset continues to operate as a standalone offering as well, serving contractors who do not use Procore.
