Time & Materials Billing Guide for Specialty Contractors and Self-Perform General Contractors

time and materials billing

Many contractors in the construction industry use Time and Materials (T&M) billing to manage project costs on complex jobs, where the scope can change at a moment’s notice. With more mega projects being built, like Data Centers and Semiconductor plants, we are seeing owners and general contractors move into T&M billing. Unlike fixed-price contracts, also known as lump sum contracts, which are another common billing agreement, T&M contracts are billed based on the actual hours worked and the materials used during the project. Although there are many benefits to this type of flexibility, there is also a need for accurate record-keeping to prevent disputes that may arise, keep parties accountable, and maintain the contractor, subcontractor, and client trust. 

The stakes can be high if you depend on T&M billing. Without accurate, transparent documentation, they can face miscommunication, delays in payment, and even loss of revenue. With more complex billing comes a need to modernize manual paper time tracking to meet today’s project demands. That’s where SmartBarrel comes in. Our timekeeping solution was designed to simplify accurate tracking and eliminate the doubts that come with T&M billing. With features like biometric facial verification, geofencing, and digital recordkeeping, SmartBarrel provides contractors with the indisputable proof they need to back up every hour billed, building trust with clients and making T&M billing smoother across the board.

Let’s dive into what makes T&M billing different from other forms of billing, the common documentation challenges contractors often face, and how SmartBarrel’s construction time tracking tools can address these issues so specialty contractors can bill confidently and accurately.

What is Time & Materials (T&M) Billing?

Time and Materials (T&M) billing is a contract that allows contractors to bill clients based on costs for labor and materials used on a job in real-time. If projects don’t follow a fixed path, this type of billing gives contractors the flexibility to adjust as needed. 

Why Contractors Use T&M Contracts

T&M contracts are especially beneficial when a project is complex or evolves rapidly. 

  1. Flexibility in Real-Time: When the project scope changes, contractors can bill for the actual time and resources spent without being bound to an initial price, which can be limiting when there are shifting demands.
  2. Adapting to Site Conditions: T&M billing makes it easy to handle unexpected labor or material needs without stopping work to renegotiate. This keeps projects moving, no matter what real-world challenges pop up.

Challenges that come with T&M Billing

The freedom T&M contracts offer also comes with the need for solid documentation. Clients expect transparency and accuracy in billing, and without clear records, contractors may face payment delays or disputes over costs. To avoid these risks, specialty contractors need reliable, real-time tracking of every hour and material used, ensuring their billing aligns with the work completed.

SmartBarrel’s tools provide contractors with the documentation they need to build client trust and make T&M billing more predictable and reliable.

Common T&M Billing Challenges

Even though the flexibility of Time and Materials billing can be beneficial to your company, it can also present billing challenges that can possibly complicate your projects and your payments. This type of system now requires you to keep accurate records that track every hour worked and each material used. Without solid documentation, contractors can quickly run into disputes over costs, delays in payment, and even potential revenue loss.

Here are the primary challenges contractors face with T&M billing:

  • Documentation Requirements: T&M billing relies on clear and consistent documentation to justify every billed hour and material used. In multi-contractor or high-turnover situations where new labor may be in the process of earning trust, accurate tracking is essential for accountability.
  • Risks of Paper-Based Tracking: Relying on traditional paper records can create issues and headaches. When you’re using manual time tracking, you may have to deal with errors, loss, and time fraud, leaving contractors open to billing issues.
  • Foremen Entering Time for Crews: When foremen log hours for their crew, it opens the door to errors, whether intentional or not. Missing or inflated hours can spark disputes with clients and stall payments, leaving contractors to untangle the mess. Real-time, verified data is the key to keeping everyone accountable and projects on track. 
  • Client Trust and Transparency: Because T&M billing requires clients to trust billed costs, they often expect full transparency. When you have clear records, you can reduce client pushback and protect yourself from any disputes that might hurt your cash flow. 

If you’re relying on outdated methods and tools, you can’t expect to maintain the level of transparency needed for your T&M billing. It’s time to level up and find an automated solution made for contractors. SmartBarrel provides reliable, real-time data that can back up every billed hour to provide the proof you need to prevent disputes and keep your projects running.
