Time-and-Material billing

What is Time-and-Material Billing?

Time-and-material billing is a method used in the construction industry where a client is charged based on the actual cost of labor and materials for a project, along with an added markup for the contractor's profit. This approach promotes transparency as customers directly pay for the time spent on the project and materials used. The advantage of this method is the flexibility it provides - if a project scope is unclear or likely to change, it can be more efficient than a fixed-price model. However, it also contains a risk for the client, with a chance that costs could increase if the construction takes longer or requires more resources than estimated. It requires meticulous tracking of working hours, materials, and equipment used. The client also needs to keep an eye on the project to avoid unnecessary costs.

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.

Voluntary Document

What is a Voluntary Document?

A Voluntary Document in the construction industry refers to a document that is not legally mandated but is often used to provide guidelines or recommendations to improve performance or efficiency in the construction process. These documents can serve various purposes such as setting industry standards, outlining best practices, facilitating coordination between different project stakeholders, or promoting sustainability. Examples of voluntary documents in the construction industry include technical specifications, quality guidelines, safety protocols, environmental guidelines, or even design criteria. While these documents are not legally binding, they often influence construction operations due to their direct impact on project quality, safety, and cost-effectiveness.

Assets

What are Assets?

Assets, in the context of the construction industry, refer to any owned resources or properties that add value and can be converted into cash. There is a vast range of assets in construction, including land, buildings, machinery, vehicles, materials, and tools. Even intangible items like contracts, licenses, brand reputation, and technical know-how are also considered assets. Investments in staff training, software systems, patents, and copyrights also represent assets as they contribute to the operational efficiency and competitiveness of the construction company. Therefore, asset management is vital in construction for optimal utilization and maintenance of these assets.
