# LienFlash — Full Reference LienFlash is a B2B SaaS platform built for construction subcontractors, suppliers, and equipment lessors who need to protect their payment rights by sending state-compliant preliminary notices on time. --- ## Product Overview In construction, payment rights are not automatic. Subcontractors and suppliers who are not in direct contract with a property owner must send a preliminary notice within a strict legal deadline after starting work or delivering materials. Missing this deadline can permanently forfeit the right to file a mechanics lien — often the only leverage a subcontractor has when a general contractor or property owner fails to pay. LienFlash automates this process end to end: - Generates the correct legal notice for the project's state - Mails it via USPS Certified Mail with Return Receipt - Provides a Certificate of Mailing and full tracking - Looks up property owner information to ensure the correct recipient LienFlash is not a law firm and does not provide legal advice. --- ## How It Works ### Step 1 — Create a Project Enter the basic project details: property address, job start date, contract amount, role (subcontractor, supplier, etc.), and general contractor information. ### Step 2 — AI Document Analysis (Optional) Upload a contract, subcontract, pay application, or Notice of Commencement. LienFlash uses OpenAI GPT-4o vision to extract and pre-fill project fields, reducing manual data entry. ### Step 3 — Review the Mailing Address Review the owner's mailing address before sending. ### Step 4 — Property Owner Intelligence LienFlash queries property ownership records to verify that the name and address entered matches the actual owner of record. This catch helps avoid sending to the wrong party. ### Step 5 — Notice Generation LienFlash generates a state-specific preliminary notice using jurisdiction-correct legal templates. The notice includes all required statutory fields for the project's state. ### Step 6 — USPS Certified Mail The notice is mailed via USPS Certified Mail with Return Receipt through the Lob API. Every send is a live USPS mail piece. ### Step 7 — Tracking and Certificate of Mailing The user receives: - A USPS Certified Mail tracking number - Delivery status (mailed → in transit → delivered or returned) - A Certificate of Mailing PDF for legal proof of send --- ## Supported States (Live) | State | Notice Name | Deadline from First Furnishing | Notes | |-------|-------------|-------------------------------|-------| | Florida | Notice to Owner | 45 days | Required for subs and suppliers not in privity with owner | | California | 20-Day Preliminary Notice | 20 days | Required for most subs and suppliers | | Arizona | Preliminary 20-Day Notice | 20 days | Required for subs and suppliers | | Nevada | Notice of Right to Lien | 31 days | Required for subs and suppliers | | Washington | Notice of Right to Claim Lien | 60 days | Required for subs and suppliers | | Oregon | Notice of Right to Lien | 8 days | Some of the tightest deadlines in the US | ### Expansion States (Waitlist — Not Yet Live) LienFlash is building support for additional states.

A preliminary notice (also called a Notice to Owner, 20-Day Preliminary Notice, or Notice of Right to Lien depending on state) is a formal written notice sent by a subcontractor or supplier to the property owner and sometimes the general contractor. It preserves the sender's right to file a mechanics lien if they are not paid. Most states require it to be sent within a short window after first furnishing labor or materials. ### What is first furnishing? First furnishing is the date on which a subcontractor or supplier first provides labor, materials, equipment, or services to a construction project. Preliminary notice deadlines are measured from this date. ### What is a mechanics lien? A mechanics lien is a legal claim against a property that a contractor, subcontractor, or supplier can file when they are not paid for work or materials provided to improve that property. A valid preliminary notice is often a prerequisite for filing a mechanics lien. ### What is USPS Certified Mail with Return Receipt? Certified Mail is a USPS service that provides the sender with proof of mailing and a tracking number. Return Receipt provides a signed delivery confirmation. Together they create a legally defensible record that the notice was sent and received — essential for construction payment disputes. ### What is a Certificate of Mailing? A Certificate of Mailing is a document that proves a letter was accepted by USPS for mailing on a specific date. LienFlash provides one for every notice sent. ### Does LienFlash provide legal advice? No. LienFlash is not a law firm and does not provide legal advice. Users should consult a licensed construction attorney for legal questions specific to their situation. ### What happens if my notice is returned to sender? LienFlash tracks USPS delivery status including returned mail. If a letter is returned, the user is notified. Sending to the owner's last known address is generally sufficient under most state preliminary notice statutes even if the letter is returned, but users should consult an attorney about their specific situation. ### Can I use LienFlash for projects in states not yet supported? Not yet. LienFlash only generates and mails notices for the 6 currently supported states. For other states, users can join the waitlist at https://lienflash.app/deadlines. ### Is my data secure? LienFlash uses Supabase for authentication and data storage, Stripe for payment processing, and Lob for physical mail. All data is encrypted in transit and at rest.
