What is Factoring?

A conditional lien waiver is a legal document used in the construction industry that states a contractor, subcontractor, or supplier will give up or waive their right to place a lien on a property, under the condition they receive their expected payment. This waiver serves as a protection mechanism for the party responsible for payment, ensuring that once the payment is made, no future lien could be placed on the property for the services or materials provided.

Conditional waivers come in two forms, tied to when you're billing:

1. ‍Conditional progress waiver: Submitted with each progress pay application during the project. It waives your lien rights for the work billed in that period, but only takes effect once you're paid for that period.‍
2. Conditional final waiver: Submitted with your final pay application at closeout. It waives your lien rights for the entire project, including retainage, but only takes effect once you receive full and final payment.

In both cases, the "conditional" part is what protects you: your lien rights stay intact until the payment actually clears, so signing early doesn't cost you leverage if a check is late or bounces.

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.

An estimate in construction is a calculated projection of the costs, time, and resources required to complete a specific project or scope of work. It includes direct costs like labor, materials, and equipment, as well as indirect costs such as overhead, insurance, and profit margins. 

Construction estimates serve as the foundation for project planning, budgeting, and decision-making, helping both contractors and clients understand the financial commitment required. Estimates can range from rough preliminary assessments to detailed breakdowns that are often refined as project details become clearer or circumstances change.

Accurate estimating is essential for subcontractors to win profitable work while maintaining healthy margins. Many successful subcontractors develop standardized estimating processes that incorporate historical cost data, current market rates, and lessons learned from previous projects to improve bid accuracy and build credibility with general contractors.

Siteline helps you be strategic with how you bid, letting you easily analyze historic payment and project trends, including seeing your fastest- and slowest-paying clients.
