Miami Beach, FL - July 13, 2026 - Every year, the U.S. construction industry loses an estimated $280 billion to slow and missed payments, according to construction finance firm Rabbet — much of it because contractors miss a legal deadline they never knew was running. LienFlash, the Miami Beach–based platform that automates preliminary lien notices, today announced its expansion into attorney-vetted demand letters, giving contractors a single place to both protect a job and collect on it. The expansion is led by founder George Leyva and president Grant Larsen.
In most states, a contractor's right to file a lien — their strongest leverage to get paid — expires within weeks of first setting foot on a job. In Florida the window is 45 days from first furnishing; in California and Arizona it is 20. Miss it, and a contractor who did excellent work can become an unsecured creditor with little recourse. Rabbet's 2024 research found that 82% of contractors wait more than 30 days to be paid, with average days-sales-outstanding in the industry running near 90 — roughly double a healthy threshold.
LienFlash was built to close that gap. Contractors, subcontractors, and material suppliers enter their job details in a short online form; the platform prepares the correct state-specific notice and mails it via USPS Certified Mail with tracking and a Certificate of Mailing, typically in under two minutes and starting at $24.99 — compared with the $200 to $500 a construction attorney commonly charges for the same document.
"For most of the trades, getting paid is still a matter of luck and paperwork nobody explains," said George Leyva, founder of LienFlash. "A contractor can do flawless work and lose everything to a deadline they never knew was running. We're turning that from a legal maze into two minutes on a phone."
The newly launched demand letter service extends LienFlash from prevention into remedy. When an invoice is already overdue, users can now send an attorney-vetted payment demand — certified, on the record, with a stated deadline to pay — for a flat $79. The company positions the two products as a two-step path: file a notice to protect the job at the start, and send a demand letter to pursue payment if an account goes unpaid.
"Protecting a job was only half the problem," said Grant Larsen, president of LienFlash. "Contractors kept asking us the same thing — what do I do when I'm already owed? The demand letter is our answer: the same speed, the same certified proof, aimed at money that's already late."
LienFlash currently serves six states — Florida, California, Arizona, Nevada, Washington, and Oregon — with additional states in development. The platform requires no subscription; users pay per document and can preview any notice or letter free before paying. A free deadline calculator on the company's website lets contractors check whether a job's filing window is still open.
