What is Bottom-of-Chain or Low-Tier?

Overhead, in the context of the construction industry, refers to the general, ongoing expenses associated with managing a construction company or project that cannot be directly linked to individual construction jobs or projects. These expenses can include administrative costs such as office rentals, utility costs, support staff salaries, and costs associated with legal compliance, insurance, and marketing. Overhead also includes costs associated with maintaining and repairing equipment, employee training, travel expenses, and team benefits. These costs are necessary for the business operation but do not contribute directly to a specific project’s profit. A proper understanding and efficient management of overhead costs are essential to maintaining business profitability and competitiveness.

Cost accounting in construction is a specialized financial practice that tracks, analyzes, and allocates every direct and indirect expense incurred on a jobsite back to a specific project or cost code.

Unlike general financial accounting—which tracks overall company revenue and balance sheets—construction cost accounting focuses entirely on project-level profitability. By monitoring actual costs against the original budgeted cost of work performed (BCWP) and original estimate, cost accounting enables trade contractors to catch budget overruns early, calculate accurate earned value, and maintain healthy profit margins across active jobs.

How Siteline Helps:
Cost accounting only yields real insights if billing keeps pace with jobsite expenses. Siteline bridges the gap between cost tracking and revenue by streamlining pay app creation, change order management, and real-time A/R reporting—ensuring the costs recorded in your job costing system turn into prompt, predictable cash flow.

A pre-lien notice, also known as a preliminary notice, is a legal document used in the construction industry to secure payment rights for subcontractors, material suppliers, and other parties involved in the construction project. It is a crucial step in securing the right to payment and can, therefore, directly impact subcontractor cash flows.

The purpose of a pre-lien notice is to inform the property owner, general contractor (GC), and other relevant parties that a subcontractor or supplier has provided labor, materials, or services to the project. By submitting a pre-lien notice, the subcontractor establishes their right to file a mechanic's lien if they are not paid for their work.

The steps to secure payment through the pre-lien notice process are as follows:

1. Pre-lien (preliminary) notice: This notice should be submitted at the start of every project, typically within a specified time frame after the subcontractor begins work or delivers materials. It serves as a formal notification of the subcontractor's involvement and their intent to protect their right to payment.
2. Notice of intent (NOI): If the subcontractor is not paid for their work after submitting the pre-lien notice, they can issue a notice of intent (NOI) to the property owner, general contractor, and other parties involved. The NOI is the final warning before filing a mechanic's lien, indicating that the subcontractor intends to take legal action to secure payment if the outstanding balance remains unpaid.
3. Mechanic's lien: If the subcontractor still does not receive payment after issuing the NOI, they can file a mechanic's lien against the property. A mechanic's lien is a legal claim that encumbers the property, preventing the owner from selling or refinancing until the debt is resolved. This action is typically a last resort to recover unpaid balances. (Check out this blog post to better understand how mechanic’s liens work.)

Siteline—the only billing software built specifically for subcontractors—centralizes and tracks billing statuses across all projects. It provides real-time notifications when payments become overdue, empowering accounting teams to take an active role in collections—like, issuing an NOI (the next step after submitting a pre-lein notice)—to promptly recover payments.
