Why an audit request needs speed, not effort
A DCAA sample request doesn't ask for a summary — it asks for the specific timesheet behind a specific labor charge on a specific date, or the exact receipt behind a specific travel expense line. Answering it well isn't about how much effort goes in eventually; it's about how fast the right document can actually be found and how clearly it supports the figure it's being asked about.
A contractor with a year of timesheets and expense reports scattered across shared drives, email attachments and paper folders can eventually answer most sample requests — just not quickly, and not without pulling someone off their regular work for days at a time during an already stressful audit window.
This page describes how timesheets, expense reports and their supporting receipts are read and organized into one traceable structure ahead of time, so a sample request becomes a lookup rather than a search.
Where ordinary recordkeeping falls short
Timesheets filed by month, not by employee or contract
A sample request for one employee's June hours means opening every June file to find the right one, rather than a direct lookup.
Receipts attached as email images, never organized
A specific travel receipt exists somewhere in an inbox, but finding it under time pressure means searching subject lines and hoping the right one turns up.
A scanned paper timesheet with no searchable text
A stack of scanned PDFs looks organized until someone actually needs to find one specific page among hundreds.
Expense amounts that don't match the receipt behind them
A transposed figure entered into an expense report, caught only when an auditor compares it directly against the attached receipt.
Why this isn't a simple filing problem
Filing documents in folders solves for “the document exists somewhere.” It doesn't solve for “find the specific figure on a specific date for a specific employee in under a minute,” which is what an audit sample request actually needs. That gap — between filed and genuinely retrievable — is where most of the scramble during an audit response actually comes from, similar to the gap a timesheet to payroll reconciliation closes on the payroll side.
What counts as evidence in an audit sample
| Document type | What it typically supports |
|---|---|
| Employee timesheet | A specific labor charge on a specific date and cost objective |
| Expense report | A travel or incidental cost claimed against a contract or overhead pool |
| Supporting receipt | The underlying vendor transaction behind an expense line |
| Travel voucher and itinerary | Business purpose and duration behind a travel expense claim |
Each of these needs to be findable on its own and tied to the specific figure it supports — a timesheet that exists but can't be quickly matched to the labor charge it's evidence for is only marginally more useful than one that doesn't exist at all, from the perspective of responding to a time-limited sample request.
What gets read
| Field | Source |
|---|---|
| Employee name, date, hours by cost objective | Timesheet |
| Expense date, vendor, amount, category | Expense report line item |
| Receipt amount, vendor, date | Attached receipt |
| Contract or cost center reference | Timesheet or expense report header, where present |
How it works
Upload timesheets and expense reports
As they're completed, or in a batch ahead of an anticipated audit window.
Each document is read
Employee, date, hours, amounts and cost objectives pulled with a confidence score.
Receipts matched to expense lines
Each supporting receipt tied to the expense report line it documents.
Mismatches flagged, not guessed
An expense amount that doesn't match its receipt, or an unclear figure, is marked for review.
Exported and searchable
Excel, CSV or JSON, with every figure traceable and filterable by employee, date or cost objective.
A sample request, answered
An auditor requests the timesheet and travel receipts behind a specific employee's three-day trip charged to a contract in March. With the year's timesheets and expense reports already read and organized, the controller filters by employee and date range.
| Result | Time to answer |
|---|---|
| Timesheet located and matched | Under 2 minutes |
| Three travel receipts located and matched | Under 5 minutes |
| Full response package assembled | Under 15 minutes |
The same request against unorganized records, scattered across a shared drive and an email inbox, typically takes the better part of a day — the difference isn't the quality of the underlying records, it's how quickly the specific one needed can actually be found.
What makes timesheet evidence specifically hard
A timesheet needs to show not just hours, but hours by cost objective — direct labor on a specific contract, indirect time, leave — for a specific date, ideally with a visible record of who entered it and when. A scanned paper timesheet or a screenshot from an old timekeeping system often has all of this information, but not in a form that's searchable or comparable across employees and periods without someone reading each one individually.
Reading timesheets the same way regardless of their original format — a modern timekeeping system's export, a scanned paper form, an older system's PDF report — is what makes a full year of records searchable by employee, date or cost objective, rather than only browsable folder by folder.
What makes expense evidence specifically hard
An expense report typically summarizes several individual receipts into line items, and the receipts themselves arrive in every format imaginable — a hotel folio, a printed restaurant receipt, a photographed gas station slip, an airline e-ticket confirmation. Matching each receipt back to the exact expense line it supports, across a year of travel and incidental expenses, is genuinely tedious work done by hand.
Manual vs. automatic
| Manual | Automatic |
|---|---|
| A sample request means searching folders and email | A sample request is a direct filter by employee or date |
| Receipt-to-expense matching done by eye, one at a time | Receipts matched to expense lines automatically |
| Response time measured in hours or days | Response time measured in minutes |
| Redone by hand for every new sample request | Same organized structure answers every request |
From one sample to a full-year population
Answering a single sample request well is useful on its own. A full incurred cost audit often samples dozens of timesheets and expense lines across an entire fiscal year, and a contractor whose whole year of records is organized the same way answers every one of those samples at the same speed as the first, rather than getting slower as the sample list grows.
Who uses this
Government contractor controllers
A year of timesheets and expense reports organized and ready before an audit sample arrives.
Contracts and compliance managers
Every figure traceable to its source the moment an auditor asks a specific question.
Outside CPAs supporting an audit response
A structured, searchable record instead of a stack of unrelated timesheet and receipt PDFs.
Program managers preparing project-level cost support
Labor and expense detail organized by contract, ready for a project-specific review.
Edge cases worth knowing
A timesheet correction — a legitimate after-the-fact adjustment with both employee and supervisor sign-off — needs to be captured as a correction with its own record, rather than silently replacing the original entry, since an auditor may specifically ask to see the correction trail.
An expense claimed in a foreign currency needs its original currency and amount captured alongside any converted figure, rather than presented only in the converted amount, since the receipt itself will show the original currency and an auditor may compare directly against it.
Why a traceable figure beats a rounded one
A summary that shows total hours or total expenses by category, without the individual documents behind each figure, is easy to trust until a specific sample request asks for one of them by name. Reconstructing that answer later means going back to the original filing system and starting over under time pressure.
Keeping the source document attached to every figure — employee, date, page reference, confidence level — turns that reconstruction from a scramble into a detail already sitting in the data, ready the moment a sample request comes in.
Paper, scan or photo — the same reading
Timesheets and receipts don't always arrive as clean, digitally generated documents. A paper timesheet gets scanned by an office manager; a receipt gets photographed on a phone in the field. Each of these goes through the same reading process — OCR first for anything that isn't already digital text, then the same field extraction — with the same confidence scoring applied regardless of source quality.
A blurry scan or an angled photo doesn't silently produce a confident wrong answer — it produces a lower confidence score on the affected fields, flagged for a second look, which is a meaningfully different, and safer, failure mode than a clean-looking export that quietly got a figure wrong right before an auditor compares it against the original.
Retention and how long evidence needs to last
Records-retention requirements for government contract documentation are set by your specific contract terms and applicable regulations, and are worth confirming directly with your compliance advisor rather than assumed — retention periods can span several years and sometimes differ by document type.
Whatever your specific retention policy requires, keeping documents traceable and organized from the point they're created — rather than only once an audit is anticipated — is what makes meeting that retention requirement in a genuinely useful way possible, not just technically compliant with a rule about keeping files somewhere.
What this doesn't do
Doesn't determine timekeeping compliance
It reads and organizes what's on the document; whether your process meets DCAA timekeeping requirements is a separate, process-level question.
Doesn't replace your timekeeping or expense system
It reads the records those systems produce and makes them traceable and searchable, rather than replacing daily entry.
Doesn't give legal or compliance advice
Any question about retention requirements, audit strategy or compliance posture belongs with your advisors.
Doesn't decide which sample an auditor will request
It makes any specific document fast to find and trace once a request comes in.
What the exported workbook looks like
The export separates timesheet and expense data into distinct, clearly labeled sheets: a timesheet sheet with employee, date, hours and cost objective for every entry; an expense sheet with date, vendor, amount and category for every line; and a receipts index linking each receipt directly to the expense line it supports.
Every row carries the confidence score and source document reference described above, visible directly in the workbook rather than tucked away in a separate log — so a figure worth double-checking, or a specific record an auditor asks for, is easy to filter to without cross-referencing a second system.
Where this fits in the broader audit picture
Timesheet and expense evidence is one piece of a broader incurred cost audit that also covers indirect cost pools, allocation bases and the final rate calculation. That broader picture, and how the pieces connect, is covered in the overview of what a DCAA audit actually checks, with this page focused specifically on the labor and expense evidence layer underneath it.
Treating timesheet and expense organization as an ongoing habit — rather than a scramble specific to an anticipated audit — is what keeps this layer ready regardless of when the actual audit notice arrives.
It's worth noting explicitly that timesheet and expense evidence tends to be the layer sampled most frequently of the three, precisely because labor is usually the largest single cost category on a cost-reimbursement contract and the one with the most individual transactions to sample from across a fiscal year. Getting this layer organized first, before tackling the broader indirect pool documentation, is often the highest-leverage place to start for a contractor building audit readiness from scratch.
