The Problem

Your Handshake
Isn't a Contract.

You showed up, did the work, went above and beyond. Then the client "forgot" the new fence line, the extra grading, or the three callbacks. Sound familiar?

Change Orders, Not Conversations Every scope change becomes a signed, dated document with a clear price before you pick up a tool.
Lien Rights, Preserved Automatically LienBolt tracks filing deadlines by state and reminds you before your right to lien expires.
Works for Every Trade Fencing, landscaping, GC, concrete, roofing, HVAC — trade-specific language baked in.
No Office. No Laptop. No Delay. Your phone is the office. Generate and send before you back out of the driveway.
Looks Professional. Gets Taken Seriously. Clients sign professional docs. They don't sign napkin notes. Instantly stand above every competitor on the street.

Real Contractors. Real Results.

They Stopped Getting Burned.

"Had a client try to walk back a $6,800 fence extension three weeks after we finished. I pulled up the Change Order we signed on-site. Conversation over. Check in hand the next day. LienBolt paid for itself a hundred times over in one afternoon."

MR
Mike Ramirez Owner, Ramirez Fencing & Gates — Phoenix, AZ

"I used to lose track of every verbal change. Now I generate a CO on the spot, the homeowner signs it on my phone screen, and I've got a PDF timestamped before I leave. Night and day."

JT
Jake Tanner GC, Tanner Construction — Denver, CO

"The Mechanics Lien feature alone is worth it. I had no idea how many rights I was letting expire. Filed my first lien in 4 minutes. That job paid in full the next week."

DL
Donna Liu Liu Outdoor Spaces — Austin, TX

"My crew is out there all day. I needed something they could use from their phones when I'm not on site. LienBolt is the only app that actually works for that."

Questions

Straight Answers.

No fine print, no runaround. These are the questions we get from contractors every day.

LienBolt templates use standard construction law language applicable in all 50 states. When signed by both parties — including via e-signature — they create an enforceable contract modification. For disputes above $10,000 or complex lien filings, we recommend consulting a local attorney.
A Mechanics Lien is a legal claim against a property securing your right to payment. If a client refuses to pay, a filed lien clouds their title — making it nearly impossible to sell or refinance until you're paid. Every state has strict deadlines (often 20–90 days after completion). Miss the deadline, lose your rights forever. LienBolt tracks it automatically.
The web app loads fully and caches your trade templates after first use. For cellular dead zones, our offline-capable PWA version queues and syncs documents once you're back online. All input data saves locally to your device automatically.
Yes — LienBolt Crew plan supports up to 5 team members, each with their own login. Foremen can generate documents with your business info auto-populated. The manager dashboard shows all documents, their status, and pending signatures. You stay in control.
Yes. LienBolt e-signatures comply with the Federal ESIGN Act and UETA, giving them the same legal weight as wet ink signatures. Each signature includes a timestamped audit trail with IP address and device information.
Your documents and client data are encrypted at rest and in transit (256-bit AES). We never sell your data to third parties. You can export all your data or delete your account at any time. See our full Privacy Policy below.
Absolutely. No contracts, no cancellation fees. Cancel from your account dashboard in under 30 seconds. You retain access until the end of your billing period. All documents remain downloadable for 90 days post-cancellation.
