Why Payroll and Timesheets Are Important

Most articles answer this with efficiency and productivity. The real answer is narrower and more serious: in a US wage dispute, your time records decide whose account is believed. If they are inadequate, the law lets an employee’s reasonable estimate stand in their place.

The short answer

Timesheets are the evidence you rely on when someone says they were underpaid: federal law requires daily and weekly hours for every non-exempt employee, and without them an employee’s reasonable estimate can decide the case.

  • The Department of Labor lists 14 records an employer must keep, and two of them, hours each day and hours each workweek, are the timesheet.
  • Time cards and wage-computation records must be kept at least 2 years, payroll records at least 3. Keeping everything for 3 years costs almost nothing.
  • No particular form or system is required. Paper, a spreadsheet or software all work if the record is complete and accurate.

The question has a legal answer, not just a business one

Search this topic and you will find the same list everywhere: timesheets improve productivity, help you bill clients, give visibility over budgets. All true, and all beside the point for a small employer deciding how much effort this deserves.

Here is the point. Under the Fair Labor Standards Act, keeping time records for non-exempt employees is not a best practice. It is a requirement written into federal regulation, with a list of what must be recorded and how long it must be kept.

And there is a consequence attached to failing, which most articles on this subject skip. In 1946 the Supreme Court decided Anderson v. Mt. Clemens Pottery Co. The rule it set out still governs wage cases under the FLSA.

“The burden then shifts to the employer to come forward with evidence of the precise amount of work performed.”

Anderson v. Mt. Clemens Pottery Co., 328 U.S. 680 (1946), after the employee has shown the work and its amount and extent “as a matter of just and reasonable inference”

The Court added that the employer may instead produce evidence to negate the reasonableness of the employee’s inference, and that if the employer produces neither, the court may award damages even though the result is only approximate. Read that as a small employer. If your records are good, the dispute is about what your records say. If they are missing, incomplete or unreliable, the dispute is about what your employee remembers, and the court may accept an approximation.

That asymmetry is the reason this matters. Timesheets do not merely help you pay correctly. They decide who has to prove what.

What actually happens in a dispute

Two employers, the same claim: an employee says they worked nine hours of unpaid overtime a week for the past two years. The only difference is the state of their records. This is an illustration of the rule, not a prediction of any case.

Records are complete

Your numbers govern

Daily hours and weekly totals exist for every week, kept for the required period.

  1. Employee claims unpaid overtime
  2. You produce daily and weekly hour records
  3. The claim is tested against the record
  4. Any genuine shortfall is identified and paid
Dispute about facts Defensible
Records are inadequate

Their estimate governs

Hours were approximate, reconstructed later, or never kept at the required level of detail.

  1. Employee claims unpaid overtime
  2. You have nothing precise to produce
  3. Their reasonable estimate stands in
  4. Burden shifts to you to disprove it
Dispute about memory Exposed
The difference is not the claim. It is who has to prove it. Mt. Clemens does not punish the employer for bad records directly. It removes the employer’s ability to contradict a reasonable estimate, which in practice amounts to the same thing.

The 14 records federal law requires

The Department of Labor lists them in Fact Sheet #21 (the regulation, 29 CFR § 516.2, groups the same information into fewer items). For every non-exempt employee, these must exist. Two of them are the timesheet.

01Full name and Social Security number
02Address, including ZIP code
03Birth date, if younger than 19
04Sex and occupation
05Time and day the workweek begins
06Hours worked each day
07Total hours worked each workweek
08Basis on which wages are paid
09Regular hourly pay rate
10Total daily or weekly straight-time earnings
11Total overtime earnings for the workweek
12All additions to or deductions from wages
13Total wages paid each pay period
14Date of payment and the pay period covered
Items 6 and 7 are the timesheet. Item 5 matters too: the time and day your workweek begins. A fixed workweek is a legal record in its own right, and getting it wrong changes which hours count as overtime.

Two things about this list are worth dwelling on.

There is no required format. The Department of Labor does not prescribe a form, a system or a time clock. Paper is acceptable. A spreadsheet is acceptable. What is required is that the records be complete and accurate. You choose the method; you do not choose whether the information exists.

Daily hours are required, with one exception. A payroll system that stores 44 hours for the week satisfies item 7 and not item 6. The exception is a fixed schedule: if an employee normally works the same daily and weekly hours, you may record that schedule and note that the employee worked it. In any week the hours differ, you must record the exact hours for each day and the week. Outside that exception, a weekly total proves very little about which days were worked.

How long you have to keep them

Two different clocks, which is the part people get wrong. Payroll records and time records are not kept for the same length of time.

Required retention under the FLSA

Payroll records, collective bargaining agreements, sales and purchase records3 years
Time cards, piecework tickets, wage-rate tables, work and time schedules, records of additions and deductions2 years

These are federal minimums. Several states require longer, and other statutes covering the same employees may require longer still. Where two rules apply, keep to the longer one.

The two-year group is the one that hurts. Time cards, the records that would answer a dispute about hours, carry the shorter period. A claim that reaches back further may find you defending it without the evidence that would resolve it.
Practical adviceKeep everything for the longer period. Three years of storage costs close to nothing, and the difference between having a record and not having one is large. There is no advantage in deleting a timesheet on schedule.

What it costs when the records fail

A wage claim is not simply a bill for the hours you missed. Two statutory features sit on top.

2×Liquidated damagesBack wages owed can be doubled unless the employer shows good faith and reasonable grounds
3 yrsLook-back for willful violationsThe standard two-year period extends to three where the violation is willful
14Records on the DOL listFor every non-exempt employee
NoneRequired formatNo system is mandated; accuracy is
General structure of 29 U.S.C. §§ 216 and 255. The exposure in any case depends on facts that cannot be generalised here, and this is not legal advice. The direction is consistent: the remedies are built to make inadequate records expensive.

There is a second cost that does not fit in a table, and for a small employer it is often larger: the time spent reconstructing two years of hours from memory, emails, rotas and bank records while the claim is live. Clean records turn that into an afternoon of pulling files. Missing ones turn it into weeks.

Paper, spreadsheet or software: an honest comparison

Pages on this topic usually list these three options and recommend the author’s own product. This comparison is judged only on what the law asks for. (This site offers free browser tools for checking time data, and none of the three methods below is one we sell.)

Three methods, judged on what the law actually asks for
MethodDaily hours capturedAudit trailSurvives 3 yearsReal costBest for
Paper timesheetsYes, if signedWeakFragileNear zeroUnder 5 staff, one site, stable hours
SpreadsheetYesNone by defaultIf backed upYour time5–20 staff, predictable schedules
Time-tracking softwareYes, automaticUsually built inYes, if you keep your exportPer user, monthlyShifts, multiple sites, overtime complexity
The honest summary: paper and spreadsheets are legal and adequate for a small, stable team. What they lack is an audit trail, a record of who entered what and when. That matters when a record is disputed, which is the only moment any of this is tested. The team-size guidance in the last column is a rule of thumb, not a legal threshold.

If you are choosing, the question is not which is best. It is which one will still be accurate in eighteen months, in your busiest week, when nobody is thinking about compliance. A spreadsheet filled in honestly every Friday beats expensive software nobody completes.

What a defensible week looks like

Abstract advice is easy to agree with and hard to act on. This is one employee’s week as the record should hold it.

Five things this record does that a weekly total cannot. It names the workweek start, so there is no argument about which week Thursday belongs to. It shows each day separately. It shows the unpaid break taken off. It keeps real minutes rather than rounded ones, which is why the total is 43 hours 23 minutes (2,603 minutes), shown as 43.38 hours. And it makes the 3.38 overtime hours visible rather than buried in one figure. The times are invented for illustration.

Five gaps that quietly break good records

These are common failures, and none of them looks like a failure at the time.

1. The workweek was never fixed

Item 5 on the Department of Labor’s list is the time and day your workweek begins. Many small employers have never set one formally, which makes every overnight shift and every weekend arguable. A shift starting Saturday at 9 p.m. and ending Sunday at 5 a.m. falls across a workweek boundary if the week starts at midnight on Sunday, and which side the hours land on decides whether they count toward overtime. The guide to overtime when a workweek crosses two pay periods works through it.

2. Weekly totals without daily hours

Payroll holds 43 hours; nothing holds the five days behind it. Unless the fixed-schedule exception applies, this satisfies item 7 and not item 6, and in a dispute about particular days it proves almost nothing.

3. Duplicate and overlapping entries

A punch recorded twice, or two shifts overlapping on the same day, inflates hours quietly. Nobody notices in a single week. Over a quarter it distorts both your payroll cost and the reliability of the record itself, and a party who finds one duplicate has a reason to question the rest.

4. Rounding that only ever goes one way

Rounding to the nearest quarter hour or similar is allowed, but 29 CFR § 785.48 requires that it average out so that employees are fully compensated over time. A policy that always rounds in the employer’s favour is not a rounding policy; it is a deduction, and it shows the moment anyone totals a quarter of punches.

5. Hours that were worked but never recorded

Answering messages after hours. Arriving early to set up. Staying late to finish. If the employer knows or has reason to know the work happened, it generally counts, and it will not be in the timesheet because nobody clocked in for it. This is a frequent source of claims, and the only defence is a culture where recording it is normal.

The pattern worth noticingFour of these five are arithmetic and consistency problems, not judgement calls, which means they can be found by checking, before anyone else checks them for you. The fifth, unrecorded work, is about habit and culture, and no tool can find hours that were never entered.

Check your own timesheets before someone else does

The timecard reconciliation tool compares a timesheet export with a payroll export, adds up hours per employee, and lists who disagrees, along with duplicate and unreadable rows. The duplicate entry checker finds repeated and overlapping shifts. The workweek boundary checker counts hours over 40 per workweek when a pay period ends mid-week. All three run in your browser and nothing you paste or load is uploaded.

They check hours, not pay, and a flagged row is something to look at, not a finding that anyone was underpaid.

Frequently asked questions

Is a timesheet legally required in the United States?

Recording the hours is required. A “timesheet” as such is not: the Department of Labor prescribes no particular form or system. Fact Sheet #21 requires that hours worked each day and total hours each workweek are recorded for every non-exempt employee, along with the other items on its list. Paper, a spreadsheet or software all satisfy this equally.

Do I need to track hours for salaried employees?

It depends on whether they are exempt. The recordkeeping list applies to non-exempt employees, and salary alone does not make someone exempt: the duties tests and the salary threshold both have to be met. A salaried non-exempt employee needs their hours recorded like an hourly one. If you are unsure which category someone falls into, resolve that first.

How long do I have to keep timesheets?

Two years under the FLSA for time cards and the records on which wage computations are based; three years for payroll records. States may require longer. Keeping everything for three years is a safe default, because storage costs almost nothing and a missing record is expensive.

Can I use a spreadsheet instead of software?

Yes, and for a small, stable team it is often the right choice, because the law does not require software. What a spreadsheet lacks is an audit trail of who entered what and when, which matters when a record is disputed. If you use one, keep backups that preserve earlier versions.

What happens if I do not have the records?

Under Anderson v. Mt. Clemens Pottery Co., an employee who proves they performed work they were not properly paid for, and offers enough evidence to show the amount and extent of it as a matter of just and reasonable inference, has carried their burden. The burden then shifts to the employer to come forward with evidence of the precise amount of work performed or to negate the inference. If the employer cannot, the court may award damages even though the result is only approximate.

Does a payroll system count as keeping time records?

Only if it retains the hours worked each day, or the fixed schedule and any exceptions to it, and not just the weekly or pay-period total. Many systems store what was paid rather than what was worked. Check what yours actually keeps.
