Timesheet Software for Government Contractors: What DCAA Actually Requires

Timesheet and accounting system deficiencies are among the most common reasons government contractors fail pre-award accounting reviews. Many small and mid-sized contractors discover too late that a basic timesheet app is not sufficient to meet DCAA timekeeping and audit requirements — often during a pre-award survey or contract evaluation process.

Finding the right timesheet software for government contractors is not just about tracking hours for payroll; it is about establishing a system of internal controls that can withstand the scrutiny of a federal audit. Many generic timekeeping solutions lack key DCAA-compliant features, potentially exposing contractors to audit findings, Corrective Action Reports (CARs), or even risks to contract eligibility and performance.

In this comprehensive guide, we will break down the exact DCAA timesheet requirements for 2026, compare the top software options, and highlight how modern features like GPS tracking and geofencing are changing the game for field-based government contractors.

Why Timesheets Are the #1 DCAA Audit Risk

In the world of government contracting, especially with cost-plus or time-and-materials (T&M) contracts, labor is typically the largest cost element billed to the taxpayer.

The DCAA’s primary mission is to ensure that the government pays only for "allowable, allocable, and reasonable" costs. If your time-tracking system is inaccurate, the government has no assurance that the labor bill you submitted actually went toward the specific project you’re working on.

The Concept of Total Time Accounting

One of the biggest hurdles for companies moving from commercial work to GovCon is Total Time Accounting. The DCAA requires that every hour an employee works must be recorded, whether it is paid or unpaid. If a salaried employee works 50 hours in a week, they must record all 50 hours, distributed across the correct projects and indirect activities (like G&A or Overhead). This ensures that the labor rate per hour is calculated accurately and that the government isn't overcharged.

Without reliable time tracking software built for government contractors, managing compliance risks becomes a manual and error-prone process that can result in frequent Corrective Action Reports (CARs) and significant administrative burden.

The 7 DCAA Timesheet Requirements (Your Software Must Meet All of These)

1. Daily Time Entry

This is the rule most frequently broken. Employees must record their time on a daily basis. You cannot wait until Friday afternoon to remember what you did on Monday. Your software must have a feature that proves the entry was made on the day the work was performed.

2. Employee Self-Certification

The employee must be the one to enter and "sign" their timesheet. In a digital environment, this means using a unique login and an electronic signature at the end of each pay period. No one else, not a manager, not HR is allowed to enter time on behalf of an employee under normal circumstances.

3. Supervisor Review and Approval

Once an employee submits their timesheet, a supervisor who has first-hand knowledge of the work must review and approve it. This creates a two-tier system of accountability.

4. Audit Trail

This is the heart of a DCAA compliant timesheet software. If an entry is changed after it has been saved, the system must maintain a permanent record of:

• The original entry.

• The new entry.

• Who made the change.

• When the change was made.

• The reason for the change (a mandatory comment field).

5. Charging to Correct Contract/Task/CLIN

The system must allow for granular time charging. Employees shouldn't just charge to "Project A." They need to charge to the specific Task Order or Contract Line Item Number (CLIN) to ensure labor distribution is accurate for billing.

6. Inclusion of Indirect Time

Timesheets must account for all hours, including leave, holidays, Jury Duty, and Overhead and G&A labor expenses like Onsite Overhead, Offsite Overhead, Business & Proposal (B&P) or Internal Research & Development (IR&D). This is essential for calculating accurate indirect cost rates.

7. No Pre-Population of Timesheets

DCAA guidance discourages automatically pre-populating timesheets with assumed worked hours. Employees are expected to personally record and verify the actual time they worked each day, rather than relying on default or system-generated entries. Any scheduled or suggested hours should require employee review, adjustment, and certification before submission.

The SumX Difference: While many platforms provide "tools" to help you track the hours, SumX ERP enforces all 7 of these requirements at the system level. Our software doesn't just suggest daily entry; it locks down the ability to edit prior days without a documented audit trail, ensuring compliance by default.

Best Timesheet Software for Government Contractors in 2026

The market for GovCon software has evolved. You no longer have to choose between a clunky legacy system and a modern app that lacks compliance. Platforms like Deltek Costpoint, SumX ERP, Unanet GovCon, and BigTime have helped push the industry toward more modern, compliance-focused timekeeping solutions.

SumX ERP Timesheet Module (Best Overall & Field Workers)

SumX has carved out a unique position in the market by solving a problem the "big players" haven't addressed: the field-based government contractor. If your team is working at a military base, a construction site, or a remote testing facility, standard web-based timesheets are often inaccurate.

• Unique Feature: GPS & Geofencing: SumX is a DCAA-ready timesheet software that integrates GPS location tracking and geofencing. You can set a "geofence" around a specific job site, the app will only allow employees to clock into that specific contract code when they are physically within the boundary.

• Mobile-First Design: While others have mobile apps as an afterthought, SumX provides a full native experience for iOS and Android, including offline mode for secure locations.

• Electronic Signatures: Integrated sign-offs that meet federal digital signature standards.

• Deep Integrations: Direct sync with payroll providers like ADP and major project accounting suites.

What to Look for When Choosing GovCon Timesheet Software

Before you sign a contract for a new time-tracking system, use this checklist to ensure the software will actually protect you during an audit.

1. Daily Entry Enforcement: Does the software allow you to send automated "reminders" or emails to employees who haven't logged time by 10:00 AM?

2. Audit Trail: If an employee changes 4 hours to 6 hours, does the system force them to type a reason?

3. Electronic Sign-Off: Does it capture a unique digital fingerprint for both the employee and the supervisor?

4. Labor Distribution Reports: Can the system automatically calculate the percentage of time spent on each contract and format it for your accounting system?

5. Mobile Offline Capability: For contractors working in SCIFs or remote areas without Wi-Fi, can the app store entries locally and sync when a connection is restored?

6. Indirect Time Charges: Does it allow you to track "Uncompensated Overtime" to satisfy Total Time Accounting requirements?

7. GPS/Geofencing: If you have field workers, how are you verifying they are actually at the job site? (SumX is the leader here).

8. Integration: Will it integrate with your existing accounting software (QuickBooks, Xero, or a GovCon ERP)?

FAQ - Government Contractor Timesheets

Q: Does DCAA require daily timesheet entry?

Yes. DCAA Manual 7641.90 states that "Labor hours should be recorded on a daily basis." Failure to do so is one of the most common audit findings.

Q: Can government contractors use paper timesheets?

Technically yes, but it is extremely risky. You must have a manual system of "ink changes" where the original entry is crossed out (not erased), initialed, and dated with a reason for the change. In 2026, auditors view paper systems with high skepticism.

Q: What is total time accounting?

Total time accounting is the practice of recording all hours worked by all employees, regardless of whether those hours are "billable" or "paid." This is required to ensure that labor costs are distributed across all cost objectives proportionately.

Q: How long must government contractors keep timesheet records?

Generally, you must retain labor records for at least three years after final payment on a contract, though some specific agency requirements may extend this to seven years to support DCAA audits.

Q: Can employees correct timesheet errors in DCAA software?

Yes. In fact, they should be the ones making the correction. The software must simply track the change in an audit log with a documented reason for the adjustment.

Conclusion: Don't Let Your Timesheet Be Your Weakest Link

In the high-stakes world of government contracting, your timesheet software is more than a utility, it’s a shield. A single failed audit can lead to withheld payments, loss of "approved" accounting system status, and a tarnished reputation with the government agencies.

By choosing a system that enforces DCAA timesheet requirements automatically, you take the guesswork out of compliance. If you have employees in the field, the need for verification is even higher. SumX provides the only solution that combines traditional DCAA rigor with modern GPS and geofencing technology to ensure your labor data is 100% accurate.
