Field service business owners often underestimate how much legal complexity sits beneath a simple timecard. Federal law sets the floor, but most states layer additional requirements on top — longer retention windows, stricter rounding rules, and in some cases, mandatory disclosure language. Getting it wrong isn't just an HR headache. Wage-and-hour violations are among the most common class-action targets for small employers, and plaintiffs' attorneys know that manual time records are easy to attack.
The federal baseline: what FLSA actually requires
The Fair Labor Standards Act (FLSA) requires employers to keep records of hours worked for non-exempt employees for at least three years, and payroll records for at least two years. The FLSA doesn't require a particular format — paper, software, or GPS records all qualify — but the record must be accurate. Under FLSA, "accurate" has a specific legal meaning: the employer is responsible for knowing how many hours employees work, and cannot rely on employees to track their own time without any verification mechanism.
Key federal rule
The FLSA places the burden of accurate timekeeping on the employer, not the employee. If your records are disputed, you bear the burden of proving the hours were incorrect.
Rounding rules under federal law
The Department of Labor permits rounding timecards to the nearest 5 minutes, one-tenth of an hour, or quarter-hour — but only if the rounding is neutral over time. A system that consistently rounds down in the employer's favor is a wage violation regardless of how small each individual rounding is. GPS-based systems sidestep this entirely by recording actual arrival and departure times rather than rounded approximations.
State-by-state requirements
The following states have requirements that go beyond or differ meaningfully from the federal baseline. This is not an exhaustive list and is not legal advice — consult your employment attorney for advice specific to your situation.
| State | Record retention | Key rule |
|---|---|---|
| California | 3 years (payroll), 3 years (time) | No rounding allowed in most circumstances after 2021 CA Supreme Court ruling. Actual times must be recorded. |
| New York | 6 years | Employers must provide employees with a written pay stub that includes hours worked. Time records must support the stub. |
| Washington | 3 years | Agri-exempt rules differ. Restaurant and hospitality industries have specific meal/rest break tracking requirements. |
| Illinois | 3 years | One Day Rest in Seven Act requires documented rest periods. Combined with BIPA, GPS consent documentation is important. |
| Texas | 4 years (for state audits) | No state wage law beyond FLSA — federal rules apply. But 4-year retention is standard for state comptroller audits. |
| Florida | 3 years | No state income tax — simplified payroll. But wage claims have a 5-year statute of limitations, so practical retention is often 5+ years. |
| Colorado | 3 years | Colorado HELP Rules (2020) require detailed rest/meal break records for hourly employees. |
| Massachusetts | 3 years | The Wage Act is aggressively enforced. Late payment of wages (even by a day) can trigger treble damages. |
| Michigan | 3 years | The Workforce Opportunity Wage Act mirrors federal, but Michigan DOL audits are common in construction and field service. |
| Arizona | 4 years | Arizona Wage Act has a 3-year statute of limitations; 4-year retention is the safer standard. |
California: the hardest state to get right
California deserves extra attention because it has the most plaintiff-friendly wage-and-hour laws in the country. A 2021 California Supreme Court ruling (Donohue v. AMN Services) effectively eliminated time-rounding for most California employers. The court held that employers cannot round meal period times — and by extension, most time-rounding practices — because electronic systems can record the exact time, making rounding unnecessary. California also requires a 30-minute uninterrupted meal period for shifts over five hours and a 10-minute rest break for every four hours of work. Every one of those periods must be documented.
California employers
If you have any employees working in California, your time records should capture exact in/out times with zero rounding. GPS-based records satisfy this requirement automatically.
Illinois: the BIPA intersection
Illinois has the Biometric Information Privacy Act (BIPA), which affects any system that captures biometric identifiers. While GPS coordinates are not biometric data, some time-and-attendance systems that use fingerprint scanners or facial recognition do fall under BIPA. More relevant for field service: Illinois GPS tracking of employees requires clear written disclosure. If you're tracking field technicians in Illinois, your employee handbook should include an explicit GPS tracking policy with a signed acknowledgment.
Practical guidance for field service operators
- →Keep all time records for at least three years at the federal minimum; default to four if you operate in multiple states.
- →If you have any California employees, eliminate rounding entirely and record actual arrival/departure times.
- →Have every employee sign a GPS tracking disclosure before enrollment — this protects you in any state.
- →Keep records in a format that can be exported for audit. Spreadsheets locked on one person's computer are not an audit-ready system.
- →Document every manager edit to a timecard with a reason and timestamp. GPS-generated records with an editable audit trail are far more defensible than pure manual records.
- →Include a GPS/location tracking policy in your employee handbook and have employees sign an acknowledgment.
The GPS advantage in a compliance dispute
When a wage-and-hour dispute goes to arbitration or court, the question is almost always: what actually happened? Manual timecard systems have no independent verification. GPS systems produce a timestamped, location-verified record that shows exactly when a technician arrived and left a job site. This doesn't eliminate all disputes — GPS can be wrong, and there are legitimate questions about time spent driving or waiting — but it dramatically reduces the employer's exposure by replacing disputed estimates with verifiable events.
Bottom line
The single best thing a field service business can do for wage-and-hour compliance is switch from memory-based time entry to a GPS-verified system with a documented audit trail.
