6 Best Preliminary Notice Software for Subcontractors 2027

Pick the category before you pick a brand

Searches for this term mix three different products. One is a service that writes, mails and sometimes records notices for you. Another is lien-rights software that tracks deadlines while your own staff sends the notices. The third is waiver software that handles the paperwork after payment. Choose the category first, because it decides who carries the deadline risk and what you pay for.

A preliminary notice is an early written notice that a subcontractor or supplier sends to the owner or general contractor so it keeps the right to file a mechanics lien later. The rules are set state by state. In Florida the same step is called a notice to owner, and the statute requires it to be served not later than 45 days after you start furnishing labor, services or materials, according to Florida Legislature (current statutes). Florida notice-to-owner deadline: 45 days is the number to calendar before you bid Florida work.

TL;DR: If you send a handful of notices a month in one or two states and want someone else to mail them, a per-notice service is the simplest fit. If you run many jobs across several states and need deadlines tied to billing, look at the lien-rights platforms. A configured workflow can beat both, but only if your job data is clean and someone owns the review steps.

Key Takeaways

• Preliminary notice rules differ by state and by project type, so any tool must show which rule set it applies before you trust its deadlines.

• Billd and Levelset publish per-notice or per-recipient prices on their own pages, which makes a cost model possible before you talk to sales.

• Handle and Siteline publish no dollar prices and route buyers to a quote, so budget a sales conversation before you compare totals.

• PreLien2Lien and Built did not show a price on any pricing page we could cite, so ask both for written pricing.

• Procore owns Levelset, which matters if your general contractors already run their projects in Procore.

• No tool removes the need for a person to confirm the form, the deadline and the recipient before a notice leaves the office.

How we evaluated these tools

This is an informed buyer's guide built from public pages. We opened each vendor's own site, read the pricing page where one exists, and checked state statutes and trade press for the rules that drive the purchase. Nothing here reports trial accounts or hands-on use.

We weighted six criteria before comparing products. Preliminary notice coverage and state rules carry the most weight because a missed deadline can cost lien rights that no price advantage can replace. The scale runs from 0, meaning not stated on public pages, to 5, meaning stated clearly with a specific mechanism.

The weights are our judgment, not an industry standard. If you work in one state with few notices, lower the coverage weight and raise price clarity, and the ranking will shift in favor of the simpler per-notice options.

Feature matrix from public pages

"Not stated" means the item does not appear on the pages we opened. It does not mean the vendor lacks the feature, so confirm every gap in writing before you sign.

Only Handle and Siteline describe deadline tracking as a core feature on the pages we opened. If alerts across many jobs are your main need, ask the other vendors to show the mechanism before you rely on it.

Pricing, checked October 26, 2026

Pricing checked October 26, 2026.

Levelset's pricing page lists Send Demand and Send Notice at $59 per recipient each, according to Levelset (checked 2026). The page names no plan tiers and does not mention certified mail. File a Lien is marked "Subscription Required" and shows "Call request" where a price would go.

Billd's pricing page is the most specific public list in this group. Billd preliminary notice: $30.00 per notice according to Billd (checked 2026). The same page lists expedited handling at $25.00 and certified mailing at $9.35, which applies only where a state requires certified mail.

Handle and Siteline publish no dollar figure. Handle's notice page offers "Contact Sales" and no price, and Siteline's pricing page says its pricing is custom and based on usage, billing volume and integration needs. Budget a quote request before you compare totals.

Each figure in this table is cited in the profile or pricing paragraph above it. Third-party review listings show other per-send figures for Levelset. We could not open those pages, so we print none of them, and a written quote is the reliable check.

A price per notice is not the whole cost. Ask each vendor whether a notice to one general contractor and one owner counts as one recipient or two, whether expedited fees stack, and whether certified mail is billed separately.

What 40 notices a year actually cost

Take a framing subcontractor who sends 40 preliminary notices a year, one recipient each, across six states. Eight of those notices go to states that require certified mail, and two are rush jobs. At Billd's $30.00 per notice, the 40 notices come to $1,200.00. The eight certified mailings add 8 × $9.35 = $74.80, and if the $25.00 expedited fee applies to each rush notice, the two rush notices add $50.00, for a total of $1,324.80. At Levelset's $59 per recipient, the same 40 notices come to 40 × $59 = $2,360.00. The DIY side has a cost too: if the subcontractor sends its own deadline texts through Twilio, the Message resource exposes 20 properties, including error_code and date_sent, according to Twilio (current docs), so a failed reminder can be caught the same day rather than at the deadline.

These totals assume one recipient per notice and that the expedited fee applies only to the two rush notices. Change either assumption and the totals move, while the per-unit math stays the same.

Vendor profiles: best fit, limits and evidence

Levelset

Levelset is a lien-rights platform that Procore acquired in 2021, as covered in the ownership section below. Its public pricing page prices notices per recipient, but it does not say what a Send Notice covers beyond that label. Best fit: a subcontractor or supplier that already runs Procore and wants lien-rights records near the project file. Limits: the pricing page names no tiers and no certified mail fees. Implementation: ask in writing how a recipient is counted, so one notice is not billed twice for the general contractor and the owner.

Billd Lien Services

Billd's pricing page describes a portal that generates, mails and records preliminary notices, mechanic's liens and waivers with no subscription cost, and it lists a notice of intent at $150.00, according to Billd (checked 2026). Best fit: subcontractors who send mostly preliminary notices and want a fixed cost per notice with nothing to cancel. Limits: a per-notice price is easy to compare, but the public page does not say how state rules are maintained or who reviews the form. Implementation: confirm which state forms the portal covers before you send a batch, and assign a person to sign off on each new job.

Handle

Handle's notice-management page describes preliminary notices, next-day lien filings through eRecording and courier services, automated waiver checks, and a statutory deadline engine, and it claims nationwide compliance across all 50 states plus Canada, according to Handle (checked 2026). Best fit: credit and A/R teams that want notices, waivers and payments in one platform and a named account manager. Limits: the page does not mention certified mail or user roles, so ask for both in writing. Phrases such as "triple-checked research" are marketing claims, not a published accuracy rate.

Siteline

Siteline is billing software for commercial subcontractors, and its lien-rights tracking is an add-on. Its pricing page lists 2 packages, Siteline Suite and Siteline Vendor Management, according to Siteline (checked 2026). Best fit: commercial subcontractors that want lien deadlines inside their billing and collections workflow. Limits: the pages we opened do not name preliminary notices as a product, so the notice coverage must be confirmed. Implementation: confirm that your billing system and job data can feed the platform, and expect a quote before a pilot.

PreLien2Lien by Tradition Software

Tradition Software's homepage describes PreLien2Lien as do-it-yourself lien software with a "Mail First Notices" option that prints first notices a subcontractor mails "whether a state requires them or not," plus certified mail tracking and PDF archiving. The homepage also describes an annual leased subscription with a price range, but it is not a pricing page we can cite, so we print no figure. Best fit: a subcontractor that wants to print and mail its own notices from software it controls. Limits: we found no public integration documentation. Implementation: request a sample notice for each state you work in and confirm the mailing and tracking steps before you rely on them.

Built

Built's Procore integration page describes tracking primary and lower-tier lien waivers and notices, bulk waiver requests, compliance flags for vendor documents, and a Procore sync for contract, invoice, payment and vendor data. Best fit: teams that already run payment applications and waivers in Procore and want releases tied to payment. Limits: preliminary notices are not named on the page, so do not buy it as your notice system without written confirmation. We found no published price on the pages we opened.

Deadlines are where subcontractors lose lien rights

Deadlines vary by state and by project type, and a single calendar rule does not cover them. A 2017 trade article describes Texas first-tier notices as due on the "15th day of the third calendar month" after work is performed, and it suggests a software trigger such as a project value above $2,500, according to Construction Executive (2017). Software that works here needs a state rule table, not one deadline.

A proposed US Tech Automations design for this pain point would start with a trigger: a new job or purchase order created in your accounting or job system. The workflow would read the project's state, owner, contract date and first-furnishing date from an export or API, calculate the notice deadline from a state rule table your counsel has approved, and write out a draft notice and a calendar due date. The prerequisites are a job export with those fields, a current rule table, and a clean owner address list. There are two human review points: a staff member confirms the form and deadline before any draft is released, and an exception queue catches any job missing a first-furnishing date. This is a configurable design, not a description of a live deployment or a measured result.

Proof of delivery and the paper trail

Weak proof is the second way subcontractors lose lien rights. In the proposed design, US Tech Automations would use a mailing event as its trigger: a certified mail tracking number is created or a delivery status changes. The workflow would write that status back to the job record, flag any notice that is undelivered or returned, and produce a per-job delivery log as its output. The prerequisites are API or CSV access from the mailing provider and a status field your job system can store. The human review point is someone who reviews every returned notice within a set window and decides on a re-send before the deadline, not after it. Like the first design, this is a proposed configuration, and it can only read the data you give it.

Ownership and vendor stability

Ownership matters more than most buyers expect. Procore completed its acquisition of Levelset on November 3, 2021, adding lien rights management to its platform, according to Procore (2021). Levelset purchase price: about $500 million according to ENR (2021), which reported roughly $425 million in cash and $75 million in Procore stock. A parent company change does not make a product better or worse, but if you use Procore and Levelset, ask how lien records move between them.

Who this is for

• Best fit: a subcontractor or supplier with recurring notices, a small admin team and a written list of the states it works in. Choose a per-notice service if you send a few notices a month and want someone else to mail them. Choose a lien-rights platform if deadlines span many jobs. Choose a waiver tool if the problem is getting releases after payment.

• Red flags: you cannot name the states you work in, you have no job list or contract data to feed any system, or you expect software to decide the legal form for you.

Common mistakes

• Buying on the lowest per-notice price without confirming the state form the vendor uses.

• Assuming one notice is one recipient when the general contractor and the owner each need a copy.

• Calendaring the deadline from the contract date instead of the first furnishing date.

• Treating a delivery confirmation as proof that the notice was valid.

• Signing a waiver before the payment it releases has cleared.

Where a simpler tool wins

US Tech Automations is the wrong first step in three cases. If you send two or three notices a year in one state, a per-notice service or a state form reviewed by your attorney is simpler than any configured workflow. If you need a filer to record a lien, a service that files and records is the product you need, and a workflow cannot replace that filing. If your job data lives on paper or in a spreadsheet nobody updates, buy a deadline calendar and fix the data first, because a workflow reading bad inputs produces confident mistakes.

Building it yourself versus buying

Zapier, Make and n8n are the usual DIY alternatives. Used well, they can keep run histories, retries, error branches and audit evidence, but you must design and own the observability, idempotency (so a retry does not send a second notice), escalation paths, access controls and ongoing maintenance. A proposed US Tech Automations design could configure a hold-for-review step and a delivery log as standard parts of the workflow, but both still need your review staff and your sign-off on the rule table. Pick the approach you can staff, because a DIY build without an owner fails quietly.

Frequently asked questions

Is a preliminary notice the same as a lien waiver?

No. A preliminary notice protects lien rights early in a project, while a lien waiver releases lien rights after payment, so the two tools solve different problems.

Do I need software for a handful of notices?

Usually not. For a few notices a year in one state, a checked state form and a calendar can cover the deadline, and a per-notice service avoids a subscription, as Billd's pricing page describes.

Does a notice service also file my mechanics lien?

Not always. Billd and Levelset both list lien filing as a separate item on their pricing pages, so check the filing fee on its own line.

Can one tool cover every state?

Ask for the state list in writing. Handle makes a nationwide claim, while the Levelset and Siteline pages we opened do not list state coverage.

Why do third-party listings show different Levelset prices?

Review sites list per-send figures that do not match Levelset's own pricing page. We could not open those listings, so rely on the vendor page and get a written quote for any number you plan to budget.

What should I ask a vendor before buying?

Ask for the billing unit definition, the state forms covered, how certified mail is billed, the audit log format, and whether job and delivery data can be exported in CSV or through an API.

Choosing before the next job starts

Start with the category. Use a per-notice service if you send a handful of notices, a lien-rights platform if deadlines span many jobs, and a configured workflow only if your job data is clean and someone owns the review steps. Get written answers on the billing unit, state coverage and certified mail before you sign.
