National Lien & Bond Claim

What National Lien & Bond Claim does

National Lien & Bond Claim (legal entity National Lien & Bond LLC, founded 1986) is a privately held Illinois-based company that provides lien compliance and construction-payment recovery services to contractors, subcontractors, material suppliers, equipment rental companies, and construction factoring firms across all 50 states and Washington D.C. Its core offering is a coordinated network of local construction attorneys and on-the-ground notice providers who prepare and serve state-specific preliminary notices, mechanic's liens, and payment bond claims, including federal Miller Act claims. The company has recovered over $13 billion in construction receivables across more than 25,000 projects since inception.

The company's technology layer is a per-seat software platform priced at $75 per user per month that integrates four core modules — Notice & Lien Filing, NLB Certified Mailing (with three certificates of proof: Mailing, Service, and Delivery), Lien Waiver Exchange, and Deadline Tracking — alongside a Document Vault and escalation pathways to collections and enforcement. The platform maintains a statutory deadline engine covering all 50 states, organized storage of filings and property research by project, and a client portal at mechaniclien.law. Usage-based billing applies to individual notices, mechanic's lien filings, contingency collections, and certified mailings.

The business model combines low-ARPU recurring SaaS revenue with higher-margin usage-based and contingency fees, supported by a sales-led, consultation-driven go-to-market motion (free consultations via phone and online intake). The company distributes primarily through attorney network referrals and direct phone sales, complemented by content marketing via a 246+ article attorney-reviewed blog, state-by-state lien law guides, webinars, and gamified educational modules. Customer acquisition is aided by a 30-day free trial and 30-day money-back guarantee.

Core offering

National Lien & Bond is a service company that prepares and files state-specific preliminary notices, mechanic's liens, and payment bond claims (including Federal Miller Act claims) on behalf of construction businesses, backed by a coordinated nationwide network of local construction attorneys and on-the-ground notice providers. It wraps this legal service delivery in a subscription software platform (priced at $75 per user per month) that tracks statutory deadlines across all 50 states and D.C., stores filings in a project-level document vault, manages lien waivers, issues certified mailing with three certificates of proof, and escalates non-paying accounts to contingency collections, lien foreclosure, and litigation through the attorney network.

Product overview

National Lien & Bond operates a unified software platform backed by a nationwide network of local construction attorneys and notice providers. The platform covers the full mechanic lien and bond claim lifecycle through four core integrated modules — Notice & Lien Filing, NLB Certified Mailing, Lien Waiver Exchange, and Deadline Tracking — plus Collections & Enforcement and a Document Vault. The platform is priced per seat at $75/user/month with pay-per-use add-ons for individual filings. Federal Miller Act claims and contingency construction collections are offered as additional service lines. The company emphasizes attorney-network distinction over generic software, positioning the platform as the delivery mechanism for state-specific legal services across all 50 states and D.C.

Broad incumbents

• e-Builder (Trimble): Capital program and construction management platform owned by Trimble, used by owners and program managers. Comparable in serving the construction payment ecosystem but at a broader enterprise level rather than the subcontractor/supplier niche NLB serves.
• BILL Holdings: AP/AR automation platform serving SMBs including construction firms. Indirect overlap in construction payment workflows; potential channel partner or competitive substitute as BILL adds vertical-specific compliance features.
• Textura (Oracle Construction and Engineering): Construction payment management and collaboration platform (now part of Oracle). Comparable as a system-of-record for construction payment workflows; broader in scope and tied into Oracle's enterprise customer base.
• CMiC: Construction ERP and project management software handling financials, project controls, and field operations. Adjacent competitor — overlaps in the construction payment workflow but is a full-suite ERP rather than a lien-compliance specialist.
• Viewpoint Construction Software: Trimble-owned construction ERP suite covering accounting, project management, and field operations. Indirect competitor: a customer standardizing on Viewpoint may be less likely to adopt a standalone lien compliance platform.
• Procore Technologies: Broad construction management platform spanning project management, financials, and now lien rights (via Levelset). Competes with NLB as part of a wider suite, but NLB's niche focus and attorney network differentiate it within lien compliance specifically.

Direct peers

• Levelset: SaaS platform for lien rights management, preliminary notices, and payment exchange; acquired by Procore in 2021. Closest direct competitor — both serve the same contractors/subcontractors/suppliers with deadline tracking and document workflow, with the key difference being Levelset's pure-software model vs. NLB's attorney-network delivery.
• Lienwaivers.io: Digital lien waiver exchange platform for construction payment compliance. Comparable product feature for the Lien Waiver Exchange module of NLB's offering, though narrower in scope (no full lien filing or attorney escalation).

Emerging players

• AvidXchange: AP automation platform with deep penetration in construction vertical. Adjacent rather than directly competing — addresses invoice payment rather than lien enforcement — but increasingly overlaps as AP automation vendors add payment-risk and lien workflows.

Others

• Liberty Mutual Surety: Major surety underwriter issuing Miller Act and Little Miller Act payment bonds. Not a direct competitor but ecosystem-relevant: NLB files bond claims against these sureties, making them a downstream counterparty rather than a substitute.
