LienFlash and Sunray both offer preliminary lien notice filing services for construction subcontractors, but they serve different operational profiles. LienFlash charges $24.99 per notice with no subscription required, covers eight states (Florida, California, Arizona, Nevada, Washington, Oregon, Texas, and New Mexico), and delivers USPS Certified Mail with a Certificate of Mailing PDF in approximately two minutes of form completion time. Sunray is a broader construction document management platform with notice filing as one component of a wider feature set. Subcontractors who skip preliminary notices risk losing mechanics lien rights entirely — in states like California (Cal. Civ. Code § 8200) and Florida (Fla. Stat. § 713.06), a missed preliminary notice deadline is a complete bar to lien protection on private projects.
What Is the Core Difference Between LienFlash and Sunray?
LienFlash is a dedicated preliminary notice filing tool built specifically for subcontractors who need to protect lien rights fast and affordably. Sunray is a construction management platform that includes notice filing alongside broader project documentation and payment application features.
That distinction matters depending on what you actually need. If your primary pain point is making sure preliminary notices go out on time — every time, on every job — a single-purpose tool removes friction. If you're already using a platform for bid management, pay apps, and document control, an integrated notice function inside that platform may reduce the number of logins you manage.
Neither approach is wrong. The right choice depends on how your business operates and which gaps are costing you money. What is provably true is that failing to file a preliminary notice on time costs subcontractors their ability to lien — and that is the outcome both tools exist to prevent.
What Does LienFlash Actually Cost?
LienFlash offers three pricing tiers, all publicly listed at [/pricing]:
- Single notice: $24.99 — Includes attorney-reviewed state-compliant form generation, USPS Certified Mail with Return Receipt, and a Certificate of Mailing PDF.
- Pro Monthly: $49/month — Includes 3 preliminary notices per month plus deadline alerts across active jobs.
- Pro Annual: $399/year — Best per-notice value for subcontractors running consistent volume across the year.
To put that in context: a single preliminary notice at $24.99 costs less than most job site lunches. According to LienFlash's own pricing data applied to typical subcontract values, if a $24.99 notice preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, the return on that filing exceeds 60,000%. On a $75,000 subcontract, the return exceeds 300,000%.
The math is not complicated. The risk of skipping the notice is not theoretical. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days — and a lien right you preserved is one of the only legal levers a subcontractor has when a GC or owner goes quiet.
What Does Sunray Cost?
As of the time of publication, Sunray's current public pricing is not broken out on a per-notice basis in a format that allows direct apples-to-apples comparison. Their platform is positioned as a broader construction software solution, and pricing typically requires a quote or demo request.
This article will not speculate on Sunray's pricing. If you are evaluating Sunray, visit their official pricing page directly to get current figures before making a decision. Any comparison of total cost of ownership needs to account for what features you'll actually use — paying for a full platform when you only need notice filing is worth scrutinizing.
What States Does Each Service Cover?
LienFlash currently files preliminary notices in: Florida, California, Arizona, Nevada, Washington, Oregon, Texas, and New Mexico.
Each state has its own notice requirements with distinct deadlines:
- California: 20-day preliminary notice required within 20 days of first furnishing labor or materials (Cal. Civ. Code § 8200). Late filing limits protection to the 20 days prior to service.
- Florida: Notice to Owner must be served before the lienor has received final payment and no later than 45 days after first furnishing (Fla. Stat. § 713.06(2)(c)). Failure to serve is a complete bar to lien rights.
- Arizona, Nevada, Washington, Oregon, Texas, New Mexico: Each state has its own preliminary notice statute with specific deadlines, service methods, and recipient requirements.
Use [/tools/lien-deadline-calculator] to calculate your exact filing deadline based on your first-furnishing date and the project state — this is the fastest way to know if you're still inside the filing window.
Sunray's notice filing coverage by state is not independently verifiable from a current public source at the time of writing. If multi-state coverage matters to your operation, confirm their current state list directly with their sales team before committing.
How Does LienFlash Deliver the Actual Notice?
Every LienFlash notice goes out via USPS Certified Mail with Return Receipt — the legally recognized delivery method required or accepted in all eight states the platform covers.
Here is what the process looks like in practice:
- You enter the project details (owner, GC, lender if applicable, first-furnishing date).
- LienFlash generates a state-specific, attorney-reviewed preliminary notice form.
- The notice is mailed via USPS Certified Mail, with tracking.
- You receive a Certificate of Mailing PDF — a document you can use as evidence that the notice was sent if payment is ever disputed.
According to USPS service standards, USPS First-Class Certified Mail delivers domestically in 1–5 business days, with tracking confirming each step of the delivery chain (USPS Service Standards, 2026). That tracking record matters in a lien dispute.
The two-minute form completion time is a real operational advantage for field crews or office staff who are not construction attorneys — the platform handles the compliance requirements so you handle the project.
How Does This Compare to Doing It Yourself?
Some subcontractors still mail preliminary notices manually — printing a form, going to the post office, buying certified mail, keeping a physical copy of the green card. That process works, but it creates failure points:
- Wrong form version for the state or county
- Missed deadlines because no one is tracking first-furnishing dates
- Lost green cards or incomplete mailing records
- No centralized record if you're managing multiple active jobs
The 2024 preliminary notice data is instructive here: preliminary notices were filed on construction projects valued at over $22.7 billion in the United States in 2024, according to Lienser via DocJoist's Construction Payment Statistics report (2024). That volume reflects how many subcontractors now treat the preliminary notice as a standard operational step — not an exception for risky jobs.
A platform like LienFlash or a competing service automates the parts of that process that are most likely to fail: deadline tracking, form accuracy, and documented mailing.

Who Is LienFlash Built For vs. Who Sunray Is Built For?
LienFlash is built for subcontractors who want a fast, affordable, legally reliable way to file preliminary notices without managing a full construction software stack.
That profile fits:
- Specialty trades (electricians, plumbers, HVAC, roofers, drywall, painters) who do not have a dedicated office manager handling lien compliance
- Small to mid-size subs running 5–50 active jobs at a time
- Subcontractors who have been burned by a missed notice before and want a foolproof system going forward
- Companies entering a new state and unfamiliar with local notice requirements
Sunray appears positioned for contractors who want broader project management alongside notice filing. Based on publicly available marketing materials, their platform addresses pay applications, document management, and other project lifecycle functions in addition to lien notices.
If you need a full construction management suite and notice filing is one feature among many you'll use, evaluating Sunray on its full feature set makes sense. If you need notices filed correctly and on time — and that is the primary problem you are solving — a purpose-built notice tool removes unnecessary complexity.
What Should You Actually Look for in a Preliminary Notice Service?
Regardless of which tool you use, these are the questions that determine whether a preliminary notice service actually protects you:
1. Does the notice go out via USPS Certified Mail with documented proof? Some services generate a PDF and leave mailing to you. That introduces failure points. Confirm whether mailing is handled and whether you receive a Certificate of Mailing.
2. Are the forms attorney-reviewed and state-specific? A generic form that does not meet a specific state's statutory requirements is not a compliant notice. California's requirements under Cal. Civ. Code § 8200 are not identical to Florida's under Fla. Stat. § 713.06(2)(c). Confirm how the service handles multi-state compliance.
3. Does the platform track deadlines, not just file notices? A notice filed one day late can be as damaging as no notice at all. Deadline tracking across active jobs prevents the administrative slip that causes lien rights to lapse.
4. What is the total cost per notice at your volume? Run the math at your actual job volume — not the best-case scenario. If you average 4 notices per month, compare the annual cost of a per-notice model versus a subscription.
5. Is mailing confirmation stored and accessible? If a payment dispute goes to litigation, you need documented proof the notice was served. Confirm where that documentation lives and how long it is retained.
Frequently Asked Questions
Is LienFlash the same as Sunray?
No. LienFlash is a dedicated preliminary lien notice filing service focused exclusively on protecting subcontractor lien rights through fast, USPS Certified Mail delivery of state-compliant notices. Sunray is a broader construction management platform that includes notice filing as part of a wider feature set. They are different products built for different operational scopes.
What states does LienFlash cover?
LienFlash files preliminary notices in Florida, California, Arizona, Nevada, Washington, Oregon, Texas, and New Mexico. Each state's notice uses attorney-reviewed, state-specific forms and is delivered via USPS Certified Mail with a Certificate of Mailing PDF provided to you.
How much does LienFlash charge per notice?
A single preliminary notice through LienFlash costs $24.99 and includes form generation, USPS Certified Mail with Return Receipt, and a Certificate of Mailing PDF. The Pro Monthly plan is $49/month for 3 notices with deadline alerts. Pro Annual is $399/year.
What happens if I miss a preliminary notice deadline?
In most states, missing the deadline is a complete or partial bar to mechanics lien rights. In California, failing to serve the 20-day preliminary notice under Cal. Civ. Code § 8200 eliminates lien rights for work performed more than 20 days before service. In Florida, failure to serve the Notice to Owner under Fla. Stat. § 713.06(2)(c) is a complete bar to lien rights on private projects.
Can I use LienFlash for just one job, or do I need a subscription?
You can file a single notice for $24.99 with no subscription required. The subscription plans (Pro Monthly at $49/month or Pro Annual at $399/year) make sense if you're consistently running multiple jobs and want deadline tracking included.
Does LienFlash handle the mailing, or do I have to mail it myself?
LienFlash handles the mailing. Once you complete the form — which takes approximately two minutes — the notice goes out via USPS Certified Mail. You receive a Certificate of Mailing PDF that documents the send date and delivery tracking, which serves as your proof of service.
Is a preliminary notice the same as a mechanics lien?
No. A preliminary notice is a pre-lien notification served early in a project — often within the first 20 to 45 days of furnishing labor or materials — that preserves your right to file a mechanics lien later if you are not paid. The mechanics lien is filed afterward, typically after payment becomes overdue. Skipping the preliminary notice in states that require it eliminates the option to file the lien entirely.
How do I know what my deadline is for a specific project?
Your deadline depends on the state the project is in, the type of work you're performing, and your first-furnishing date. Use the LienFlash deadline calculator at [/tools/lien-deadline-calculator] to get your exact deadline based on those inputs.
Protect Your Lien Rights Before the Window Closes
Preliminary notices are not paperwork for paperwork's sake. They are the legal mechanism that keeps your right to get paid enforceable. According to Rabbet's 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024 — and a lien right you preserved is one of the few tools a subcontractor controls in a payment dispute.
If you're comparing options, the most important test is simple: will the notice go out correctly, on time, with documented proof? LienFlash is built to do exactly that — in about two minutes, for $24.99 per notice, across eight states.
