What is a Notice of Commencement (NOC)?

What is a Notice of Commencement (NOC)?

A Notice of Commencement (NOI) is a legal document filed by general contractors (GCs) to formally declare the start of a construction project. In addition to establishing an official record of when construction began, it also provides essential information about the project—property details, project scope, contact information for key project stakeholders, etc. In some states, it may be referred to as a Notice of Project Commencement, an Affidavit of Commencement, or a Notice of Contract. 

For subcontractors, NOCs are important because they determine when you need to file paperwork to protect your lien (and thereby, payment) rights. Once the owner or GC files an NOC, it often changes the deadlines for when you must submit preliminary notices and mechanics’ liens. These documents contain vital project information, including:

  • legal property descriptions,
  • owner details,
  • GC information, and
  • surety data.

In most states where NOCs are required, they must be posted at the job site and recorded with the county clerk’s office. Subcontractors should be aware that failing to respond properly to an NOC could result in losing their right ot file a lien if a payment issue arises.

Staying informed about documentation like NOCs is crucial for securing payment on construction projects.

Office

What is an Office?

An office in the construction industry refers to a space, whether portable or fixed, utilized for administrative tasks such as managing construction plans, processing permits, overseeing contracts, and coordinating construction activities. It may be onsite or offsite, functioning as the hub for project management. Onsite offices, often seen in portable cabins or trailers, serve as the command center monitoring real-time construction progression. They store important documents, house communication devices, and serve as a meeting spot for employees and visiting clients. Offsite offices, on the other hand, handle larger administrative tasks such as project bidding, procurement, and capital management. Moreover, it acts as a central contact point for multiple construction sites. Both types of offices play a pivotal role in ensuring a smooth, sustainable, and efficient execution of construction projects.

Costs in Excess of Billings

What is are costs in excess of billings?

Cost in excess of billings (CEB), or underbilling, refers to a cost incurred by a subcontractor for work performed that has yet to be billed to the general contractor at any point in time. This is a somewhat common scenario that can arise when the cost of work expenses (labor, materials, subcontractors, etc.) hit before billings go out.

There are a few factors that can create this timing gap and lead to underbilling. These include:

  • Progressive billing schedules: Many construction projects have billing schedules that are based on predefined milestones or stages of completion. However, costs are being incurred continuously as work progresses. This causes costs to build up ahead of invoices between billing cycles.
  • Upfront and early-stage mobilization: Significant upfront costs go into things like materials, equipment, permitting, and mobilizing job sites before physical work even begins—especially for subcontractors. These costs typically accumulate before clients are billed.
  • Pending change orders: Costs related to change orders often hit weeks or months before details are finalized and approved for billing. Diligently tracking pending change orders is crucial to ensure you ultimately collect on all revenue owed from approved changes.
  • Project delays: In construction, delays are inevitable. If and when delays push out project milestones, billable events can slide further out from when the costs were incurred. These timeline gaps widen the difference between accrued expenses and billings-to-date.

CEB is reflected on financial statements as assets because it represents an unbilled receivable for revenues that will later come. Therefore, regularly monitoring CEB is critical to maintaining healthy business operations as it helps subcontractor accounting teams:

  • Understand true project economics: CEB helps reveal the full profitability picture by linking incurred costs with unbilled receivables, which in turn supports more accurate revenue forecasting and job costing projections.
  • Gain greater cash flow visibility: Because CEB tracking shows how much money is flowing out that’s tied up in work completed but not yet paid for, it helps them better plan and manage their cash for future expenses.
  • Monitor project health: Unexpected CEB spikes could signal problems like cost overruns. Regularly comparing CEB status with the original budget is key to assessing a project’s overall health.
  • Collect revenue in full: No one wants to work for free. Tracking CEB ensures that all pending receivables are ultimately invoiced and collected.
  • Stay compliant: CEB reporting is required for percentage-of-completion revenue recognition, which is an important accounting standard for billing teams to adhere to.

Effective CEB oversight is much simpler with the right tools in place. With Siteline, you can easily track costs in excess of billings on each project to ensure no completed work goes unbilled. Siteline monitors all pending change orders through a project's lifespan, too, helping teams get approval quicker and convert unbilled work into invoiced revenue.

Overbillings

What is Overbilling?

Overbilling (or billing in excess of costs) occurs when you’ve invoiced your client for more work than you’ve actually completed or incurred costs for. In other words, it represents getting paid ahead of your work schedule.

Here’s how it works: If you’re a concrete subcontractor on a $100,000 job and you bill 50% upfront ($50,000) but have only completed $30,000 worth of work, that $20,000 difference is your billings in excess of costs. You owe your client that work, and until you complete it, that $20,000 remains as a liability on your balance sheet.

For subcontractors, understanding billing in excess of costs is essential because it can be a strategic cash flow tool when used carefully. For example, when bidding on a job, you can be smart about how you structure your schedule of values (SOV)—breaking work down into more detailed line items that allow earlier billing. However, this strategy requires regular monitoring to ensure:

  • Your billing somewhat aligns with your actual percentage complete, and 
  • The remaining contract value will still cover your remaining costs.

The biggest risk of overbilling is thinking your margins look better than they are, simply because you’re collecting cash faster. Surety companies and lenders also scrutinize overbillings closely, as excessive amounts can signal poor project management or potential cash flow problems down the road.

With Siteline, you can easily track whether you’re billing in excess of your costs by pulling your month-to-month incurred costs and comparing them against your billing progress. This real-time visibility helps ensure you’re billing appropriately while maintaining realistic profitability expectations.
