The Power of Digital T&M Tracking and Out of Scope Work

Time and materials (T&M) work plays a vital role in construction—especially when it comes to out-of-scope tasks, rapid change orders, and field-directed work. But with flexibility comes risk. T&M billing is often vulnerable to misreporting, disputes, and even fraud. Whether it’s labor padding, material overbilling, or manipulated approvals, inaccurate T&M tracking can severely impact project margins and stakeholder trust. Fortunately, digital T&M tracking is creating transparency and changing the game.

The Risks of Manual T&M Tracking

Traditional T&M tracking methods—paper tickets, handwritten notes, and spreadsheets—lack built-in verification. Without timestamps, approvals, or digital records, there’s no easy way to validate when labor occurred or how materials were used. This leaves contractors exposed to the following:

• Labor Time Padding: Inflated labor hours without evidence of actual time spent.
• Material Misreporting: Listing materials never used or reused from other jobs.
• Overbilling: Doubling up on charges or misapplying billing rates.
• Lost Change Orders: Untracked T&M slips that don’t get submitted in time—or at all.

These issues create friction with general contractors and owners, who often challenge the validity of T&M charges. Approval delays can stall payment, erode trust, and threaten future opportunities.

Digital Tools Provide Accountability

Digital T&M tools like Rhumbix introduce structure, accuracy, and transparency into a traditionally chaotic process. By enabling real-time tracking with digital approvals and timestamped records, contractors gain an auditable history of every task performed—and every dollar billed.

Here’s how digital transparency prevents fraud and builds credibility:

1. Timestamped Labor and Material Entries

Rhumbix captures labor hours with actual clock-in and clock-out times, tied directly to workers in the field. Every entry is time stamped and geotagged, showing when and where work was completed. The same applies to material usage—digital records allow teams to link materials used to specific activities, complete with time and crew data.

This eliminates guesswork and deters padding because a digital trail must go back every hour and unit.

2. Supervisor Approval Workflows

Digital T&M solutions include built-in approval workflows. Supervisors or project managers must verify entries before they are submitted, adding a second layer of accountability—every line item is reviewed, confirmed, and signed off in real-time.

Supervisors can use mobile devices or tablets on the jobsite to review and submit T&M records at the end of the shift, ensuring nothing slips through the cracks.

3. Audit Trails and Change Order Leverage

With a complete log of labor, material, and equipment entries, contractors gain a decisive advantage in change order negotiations. When presented with consistent, data-backed records, owners and GCs are more likely to approve T&M charges. Digital transparency helps answer common questions:

• Who did the work?
• When was it performed?
• What materials were used?
• Was the change authorized?

This information on hand speeds up the change order process and strengthens your case—especially in disputes.

Expert Tips: Presenting Data to Minimize Pushback

Presenting digital records effectively is just as important as capturing them. Here are four expert tips to gain faster approval and minimize owner pushback:

Group Entries by Task or Cost Code

Rather than submitting a giant log, organize T&M entries by activity or cost code. This helps owners and GCs see how each charge connects to the project scope and understand the value delivered.

Include Visual Proof When Possible

Rhumbix allows teams to attach photos, sketches, and field notes to T&M records. Use this to your advantage—show before-and-after images of work completed to reduce subjectivity and demonstrate need.

Highlight Approved Changes

Use your digital system to show a timeline of approvals: when the work was requested, approved, and completed. This prevents debates about whether the work was authorized and helps validate your claims.

Provide Summaries with Detail-on-Demand

Include a high-level summary of hours, materials, and total cost and drill-down links to supporting details. Owners and GCs appreciate clarity but want the option to review granular data if needed.

Real Impact: Faster Payments and Stronger Relationships

When T&M is tracked digitally, the benefits go beyond fraud prevention:

• Faster Payments: With clear, approved records, there’s less back-and-forth. Owners approve charges quickly and process payments sooner.
• Fewer Disputes: Transparent data builds trust and minimizes second-guessing.
• Higher Win Rates on Change Orders: Detailed digital records provide leverage and clarity.
• Improved Forecasting: Historical T&M data can be used to benchmark future change orders and improve estimating.

Why move to digital T&M tracking?

Labor costs are rising, material prices remain volatile, and margins are thin. In today’s environment, contractors cannot afford inaccurate T&M tracking, whether intentional fraud or accidental misreporting. Paper-based processes invite costly mistakes.

Digital transparency is no longer a luxury—it’s a requirement for risk management, profitability, and competitive advantage.
