Notice of Intent to Lien (NOI)

What is a Notice of Intent to Lien (NOI)?

A notice of intent to lien (NOI)—sometimes called an intent notice or notice of non-payment—is a legal document that serves as a final warning from a subcontractor or supplier to the property owner, developer, or general contractor (GC) indicating their intent to file a mechanic’s lien against the property in the event of non-payment.

The purpose of an NOI is two-fold: First, it protects the subcontractor’s or supplier's rights to establish a legal claim against the property, allowing them to file a lien—or pursue legal action—if the outstanding payment is not made within a specific time frame. Second, it motivates the responsible party (i.e., property owner, developer, or GC) to settle the outstanding payment(s). This is because once a mechanic’s lien is filed, the property owner can’t sell or refinance the property until the debt is settled.

Currently, NOIs are only legally required in nine states:

  • Arkansas (10 days before filing lien)
  • Colorado (10 days before filing lien)
  • Connecticut (Within 90 day lien period)
  • Louisiana (material suppliers on residential projects 10 days before filing lien)
  • Missouri (10 days before filing lien)
  • North Dakota (15 days before filing lien)
  • Pennsylvania (30 days before filing lien)
  • Wisconsin (30 days before filing lien)
  • Wyoming (10 days before filing lien)

However, regardless of state requirements, sending NOIs can be a beneficial and inexpensive step that increases subcontractors’ chances of getting paid (ideally without actually having to file a lien). Note that subcontractors must first submit a pre-lien (or preliminary) notice before submitting an NOI. Making both of these a standard part of accounting processes for past-due payments can improve A/R collection processes—and get payments in the door faster.

Along this vein, Siteline empowers subcontractors by providing visibility into outstanding payments across all projects, alerting them when it's time to pursue overdue balances—or issue an NOI for the most persistent cases.

Equity Turnover Ratio

What is an Equity Turnover Ratio?

An equity turnover ratio is a financial metric that is highly relevant within the construction industry. Essentially, it measures how efficiently a construction company leverages its equity to generate revenue. The ratio is calculated by dividing the company’s annual sales by average shareholder equity. The resulting number indicates how many times the company has turned its equity into revenue during a given year. A high equity turnover ratio is typically a good sign, indicating a company’s efficient use of its shareholder’s equity. It reflects the company's ability to manage its operations and utilize its assets effectively. This ratio is particularly important in the construction industry as it involves high capital expenditure and risk. Underinvestment or overinvestment can negatively impact profitability. Therefore, this ratio can be a key determinant of a construction company's financial health and operational efficiency.

Change Order

What is a Change Order?

A change order is an official amendment to a construction contract that modifies the original scope of work, timeline, or contract price. Unlike simple invoice adjustments, change orders require formal documentation and approval from all project parties before payment can be made. These modifications happen frequently in construction projects as conditions change, unforeseen issues arise, or clients request additional work beyond the original contract specifications.

For subcontractors, proper change order management can make the difference between getting paid for extra work and eating the costs. The challenge goes beyond just documenting changes—it's staying on top of approvals, tracking work that's moving forward without final sign-off, and making sure everything gets billed correctly. Too often, change orders get lost in email chains, verbal requests never get formalized, or approved changes don't make it into the next billing cycle, leaving subcontractors stuck with unbillable work. (For a detailed breakdown of change order processes and best practices, check out our change order guide.)

Siteline eliminates these change order headaches by tracking approval status in real-time, identifying which change orders are proceeding without final sign-off, and automatically incorporating approved changes into your billing schedule. With Siteline, you'll never lose sight of a change order again. Request a personalized demo to see how Siteline can protect your payments.

Project Cost Report

What is a Project Cost Report?

A Project Cost Report in the construction industry is a comprehensive document that provides detailed information about the estimated and actual costs associated with a construction project. This report is an integral part of the overall project management and facilitates financial transparency. It includes details like labor costs, material expenses, equipment costs, indirect costs and overheads, and is usually updated on a regular basis - often weekly or monthly. The report helps in tracking budget variations, identifying potential financial risks, and aids in making informed financial decisions. It plays a crucial role in ensuring that the project is delivered within the stipulated budget.
