What is a Time and Materials Contract?

Markup in the construction industry refers to the percentage increase added to the actual costs of construction projects to determine the selling price. The markup covers overhead expenses, such as administrative costs, and ensures the contractor makes a profit from the project. The percentage can vary greatly based on factors like the complexity of the project, competition in the local market, and the contractor's reputation and experience. Careful consideration is needed when deciding the markup as too high can make a contractor's bid uncompetitive, while too low may not cover all expenses or allow for a reasonable profit margin. A good understanding of the project, accurate cost estimations, and market research are crucial for determining an appropriate markup.

Factoring in the construction industry refers to a financial service where a business sells its unpaid invoices, usually at a discount, to a third-party factoring company (the factor). This process provides the company with immediate cash flow to cover business expenses, like paying for supplies or labor wages. It's like a financial tool to keep up with the industry's fast pace where immediate payment is commonly required. The third-party factor then takes the responsibility to collect full payment from the customer. This method is particularly useful in the construction industry, where projects can be lengthy and cash flow stability is crucial.

A payment application (or pay app) is a comprehensive collection of documents that construction contractors submit to request progress payments throughout a project. Rather than just a simple invoice, payment applications include multiple forms and supporting documentation that prove what work was completed, which materials were used, and what payment is due. The typical pay app package includes: 

• an application for payment form, 
• a continuation sheet with schedule of values details, 
• lien waivers, and 
• often backup documents like material receipts and payroll reports. 

Payment applications are submitted on predetermined schedules—whether monthly, at project milestones, or when specific percentages of work are completed—and serve as the primary billing mechanism for longer, higher-budget construction projects.

For subcontractors, mastering payment applications is critical because they directly impact cash flow and project profitability. The process involves coordinating between accounting teams, project managers, and vendors to gather all required documentation before submission deadlines. Common mistakes—like using incorrect forms, missing documentation, math errors, or late submissions—can delay payments and disrupt cash flow. Many GCs have their own custom forms and specific requirements, making attention to contract details essential.
