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.

Equity

What is Equity?

Equity in the construction industry refers to the financial investment made by the stakeholders in a construction project. It's essentially the difference between the overall project cost and the amount borrowed to finance it. The capital is often fund supplied by owners, investors, or shareholders. These entities get a return on their investment either through project profits, or an increase in the value of the project, thus, equity provides them with ownership rights. Interestingly, a high equity stake in projects usually indicates low leverage and low financial risk. The construction industry relies heavily on equity, particularly during large-scale projects as these require substantial financial backing. Consequently, a contractor with a higher level of equity is often regarded as more stable and trustworthy.

General Ledger (G/L)

What is a General Ledger (G/L)?

A General Ledger (G/L) in the construction industry is a fundamental financial tool for recording all financial transactions of a construction company including assets, liabilities, equity, revenue, and expenses. It not only reflects every financial transaction related to a construction project, but also contains crucial details such as date, description, and transaction amount. Essentially, the G/L acts as the core of a construction company's financial record system where all transaction data from sub-ledgers or modules, such as accounts payable, accounts receivable, and cash management, are consolidated. It provides a comprehensive financial picture necessary for reporting and strategic decision-making in the construction business. By regularly maintaining and auditing the G/L, construction companies can ensure financial accuracy and compliance, as well as evaluate their financial performance and stability.

Lien Waiver

What is a Lien Waiver?

A lien waiver is a legal document used in the construction industry that is often exchanged between parties involved in a construction project. This waiver essentially absolves or "waives" the claimant's (typically a project participant like a contractor, subcontractor, or supplier) right to impose a lien on the property for the amount they have been paid. It's often used upon payment to ensure that the payer is protected from double payment or any encumbrances on the property related to payment disputes. There are four general types of lien waivers: conditional and unconditional, each of which can be used for progress or final payment. Each type has its own legal implications, so it's important to understand them fully before signing.
