Every Unsecured Invoice Is a Donation Waiting to Happen.
Your lien rights on a delivery start expiring the day the truck leaves the yard — not the day the invoice goes late. LienFlash files the preliminary notice that keeps every job account secured. And when an account goes quiet anyway, we send the attorney-vetted demand letter that gets it moving — certified mail, same day.
The Deadline Is Statutory
The Clock Starts at First Furnishing. Not First Invoice.
Most credit managers track receivables from the invoice date. The lien statute doesn't care about your invoice date. In every state we serve, your right to secure a job account begins expiring from the date materials were FIRST furnished to the project. By the time an account is 60 days past due, the legal window to secure it has usually already closed — and that receivable is now an unsecured handshake.

There Are Only Two Kinds
Two Kinds of Suppliers. One Difference.
Same material. Same customer. Same unpaid invoice. The only thing that separates the supplier who gets paid from the one who eats the loss is a two-minute notice mailed on time.
An unsecured invoice.
No notice on file. The receivable becomes a line item in a bankruptcy schedule, behind the bank, behind the bonding company, behind everyone. Average recovery: pennies — eventually.
- No claim against the property
- Last to get paid in a bankruptcy
- Written off when the job goes bad
A secured receivable.
Notice filed at first furnishing. The claim attaches to the property itself. You're negotiating from the front of the line — usually before a lawyer ever gets involved.
- Enforceable claim on the property
- Priority when money gets tight
- Paid — because the leverage is real

A supply house runs credit the way it's always been run: open the account, deliver the material, invoice net 30, make the calls at 60. It works — until one general contractor stops answering.
The jobs were real. The deliveries were signed for. But when the attorney finally looked at the file, the question wasn't whether the money was owed. It was whether a notice had gone out within the statutory window after the first delivery. It hadn't. Nobody had ever told the credit desk that the window existed.
That's the gap LienFlash was built to close. Not collections. Not litigation. The boring, two-minute filing at the START of every account that determines which pile your receivable lands in at the END.

The Step Most Credit Desks Skip
When an account goes quiet, the next step isn't a collections agency.
Every credit desk knows the sequence: net 30 becomes 60, the calls get shorter, the promises get vaguer. Somewhere between "the check's coming" and the write-off meeting, there's a step most suppliers skip — the formal demand.
LienFlash prepares and mails your demand letter: attorney-vetted, on the record, USPS Certified with delivery proof. It states exactly what's owed, sets a deadline to pay, and signals the thing that changes payment behavior — this supplier documents everything.

Does sending a demand letter burn the customer relationship?
A certified demand letter is standard credit practice — the formal step between a phone call and a collections referral. Most customers read it exactly that way: this account is now being handled by the book. It's the accounts that drift silently into collections that end relationships; a clear, professional demand with a pay-by date usually saves them.
