Why timesheets become an existential issue in GovCon

In a commercial company, a sloppy timesheet is a payroll annoyance. In a government contractor, it's a finding — and findings on labor accounting are among the fastest ways for a small contractor to lose the right to bill cost-reimbursable work. The Defense Contract Audit Agency (DCAA) doesn't just check that the math adds up; it checks whether your system for recording labor is trustworthy, because on a cost-plus contract the taxpayer is paying for the hours your people report. If the auditor can't trust the hours, they can't trust the bill.

The trap for small primes and subs is that timekeeping feels like a solved problem — everyone has some timesheet — right up until the first audit, when "some timesheet" turns out to be exactly the kind of system that fails. This is a practical, recruiter-and-HR-facing guide to what DCAA-compliant timekeeping actually requires; it is not legal or accounting advice, and your DCAA-experienced accountant or consultant is the right partner for the formal system description.

The rule that surprises everyone: total time accounting

The foundational DCAA expectation is total time accounting — every employee records all hours worked, against all cost objectives, every day. Not just the hours billed to a contract. All of them.

This is the part commercial-minded teams get wrong. If an exempt salaried engineer works 50 hours in a week and only logs the 40 they're "paid for," the labor distribution is wrong and the indirect rates built on it are wrong. Total time accounting means:

  • Direct hours charged to specific contracts or task orders.
  • Indirect hours charged to the right pool — B&P (bid and proposal), IRAD, overhead, G&A, paid leave.
  • Uncompensated overtime for salaried staff is still recorded, even though it doesn't change their pay, because it changes how their cost is distributed.

Every hour lands in a charge code. No hour is invisible. That single principle is what most non-compliant systems violate.

Daily entry, by the employee, in their own words

DCAA cares enormously about how and when hours get recorded, because the integrity of the data depends on it:

  • The employee records their own time. A manager or admin filling in someone else's timesheet is a classic red flag — the person who did the work is the only one who can attest to it.
  • Time is entered daily, contemporaneously, not reconstructed from memory at the end of the pay period. "I think I spent about two days on that contract" is precisely the kind of estimate the rule exists to eliminate.
  • Corrections are visible, never erased. If an entry changes, the original value, the new value, the reason, the person, and the timestamp must all survive. Whiting-out a paper timesheet or silently overwriting a digital one destroys the audit trail — and the audit trail is the control.
  • Both employee and supervisor approve. The employee attests the hours are accurate; the supervisor reviews and approves. Two roles, two sign-offs.

The audit trail is the whole point

If you take one thing from this: a DCAA-compliant timesheet system is defined less by what it lets people enter and more by what it refuses to let them hide. An auditor's core question is "can someone change reported labor without leaving a trace?" If the answer is yes, the system fails regardless of how accurate the numbers happen to be.

A passing system produces, for every entry, an immutable record: who entered it, when, against which charge code, every subsequent edit, who made it, when, and why. That's why total time accounting and a tamper-evident log go together — the rule wants all the hours, and it wants proof that the hours weren't quietly rewritten later. In Hosting HR, timesheets capture daily entries against charge codes with an immutable edit history and a two-step employee/supervisor approval, so the audit trail is a byproduct of normal use rather than something you reconstruct under pressure.

Charge codes, leave, and the labor distribution

The structure your hours flow into matters as much as the hours themselves:

  • Set up charge codes that mirror your contract and indirect structure — one per active contract/CLIN, plus the indirect pools. Employees should only see the codes they're authorized to charge, so a benched engineer doesn't accidentally bill a contract they're not on. (Keeping bench time charged correctly to overhead or B&P instead of a contract is its own compliance point.)
  • Tie paid leave into the same system. PTO, sick, and holiday hours are part of total time accounting too; they flow to the right indirect treatment. Conflating leave types is both a wage-law and an accounting problem — see writing a PTO policy and getting accrual right and the value of tracking a separate balance per leave type.
  • Reconcile timekeeping to payroll and to billing. The hours recorded, the hours paid, and the hours billed have to agree. Gaps between them are exactly what an auditor pulls a sample to find.

Build the habits before the audit, not during it

DCAA compliance is far more about consistent daily discipline than about any single feature. Most findings trace back to behavior, not software:

  • Train everyone on the rules, including senior staff who assume timekeeping is beneath them — leadership charging sloppily is a favorite audit finding.
  • Enforce daily entry with gentle automation — a reminder for missing days beats a month-end scramble and a reconstructed timesheet.
  • Make the floor-check answer easy. A DCAA floor check asks a random employee what they're working on and whether it matches their timesheet. If your people charge daily and honestly, that's a non-event. If they batch-enter at month end, it's a finding waiting to happen.
  • Keep a written timekeeping policy every employee acknowledges, the same way you'd handle any new-hire paperwork — the policy is part of what the auditor reviews.

The bottom line for a small contractor

You don't need an enterprise accounting suite to pass a DCAA timekeeping review, but you do need a system that enforces the non-negotiables: total time accounting, daily self-entry, authorized charge codes, dual approval, and an edit history nobody can erase. Get those habits running on every contract from day one and the audit becomes a review of records you already keep correctly — not a fire drill. The contractors who fail aren't the ones with the cheapest tools; they're the ones who treated timekeeping as paperwork until an auditor treated it as the control it actually is.
