WIP Reconciliation Audit — Two Weeks, Fixed Fee

Does Your WIP Schedule
Actually Tie to
Your Ledger?

A WIP reconciliation ties your work-in-progress schedule, recognised revenue and cash position line-by-line to your general ledger — then tells you, in writing, where they disagree and why.

Four things a WIP reconciliation turns up almost every time

None of these are exotic. They're the predictable consequence of a schedule maintained by hand alongside a ledger that keeps moving.

🔢

Contract Values That Disagree

The WIP schedule, the project master and the executed change order log carry three different numbers for the same job.

Estimates That Stopped Moving

Cost-to-complete figures unchanged for three months on jobs actively burning cost. The margin shown is fiction.

📋

Formulas That Quietly Broke

A formula dragged one row short. A hardcoded override entered in a hurry and never removed. Both survive for years.

📊

Period Assignment Drift

Posted date versus entry date pulls transactions into different months, so WIP revenue and the income statement never quite agree.

A WIP reconciliation in two weeks,
three phases, ten structured tests

The clock starts when the data arrives complete. Everything is read-only — we extract and analyse, and never write back to your ERP. The audit diagnoses and quantifies; it does not remediate. That boundary keeps the fee fixed and the scope honest.

1

Extract & Load

You send GL transaction detail, chart of accounts, the project master, your current WIP schedule plus the prior six months, AR aging, the change order register, and trial balances for the reconciliation periods. Flat exports are fine — no API access or security review required to begin.

2

Run the Ten Tests

Each test compares two sources that should agree and quantifies the gap where they don't. Every variance gets a dollar figure, a root cause, and a classification: data problem or process problem. One round of clarifying questions with your controller, not unlimited access to their calendar.

🔍 Ten reconciliation tests, documented
3

Findings & Readout

Findings ranked by materiality, with the effort required to close each one and who owns the fix. Ninety minutes with your CFO and controller to walk through it, ending with a fixed-fee build scope quoted from what was actually found rather than from guesswork.

📈 Four written deliverables + 90-minute readout
A clean result is still a result. If everything ties, you get documented confirmation that your WIP schedule is sound — which is worth having in front of a lender, a surety or an auditor. This is framed like an audit opinion, not a fishing expedition.

The ten WIP reconciliation tests, in order

1️⃣

Ledger Tie-Out

Whether revenue less cost of sales less overhead, computed from transaction detail, reproduces reported net income. Surfaces account-range definitions, which book is authoritative, and how periods get assigned.

2️⃣

Transaction Integrity

Duplicated transactions from connector or import behaviour, unreversed prior-period entries, and orphaned records with no valid dimension.

3️⃣

WIP Cost to GL Cost

Cost-to-date on the WIP schedule against general ledger cost of sales, job by job.

4️⃣

WIP Revenue to P&L

Earned revenue on the WIP schedule against recognised revenue in the ledger for the same period.

5️⃣

Contract Value Integrity

Contract on the WIP against the project master against executed change orders. This is where individual jobs turn out to be carrying the wrong number.

6️⃣

Cost Estimate Integrity

Placeholder values, blanks, estimates below cost-to-date, and figures that haven't moved while cost has.

7️⃣

Over / Under Billing Roll

The WIP billing position against the balance sheet asset and liability accounts that should mirror it.

8️⃣

Backlog

Whether remaining-to-bill is computable at all, and whether it ties to contract value less billings to date.

9️⃣

Cash

Bank general ledger accounts against reconciled bank balances for the same date.

🔟

Dimensional Hygiene

Unassigned project managers, missing profit centres, project status drift, and absent close-out dates — the quiet causes of reports that don't foot.

What WIP reconciliation findings look like

Below is a worked WIP reconciliation on a fictional $80M commercial contractor with 24 active jobs. Every figure is synthetic and illustrative — these are not client dashboards and no client data appears anywhere on this page. They show the shape of the output, not anyone's numbers.

The centrepiece view. 26-011 Midtown is highlighted because its estimated total cost sits within $100K of contract value — a 1.6% margin that almost always means the estimate is stale rather than the job being genuinely underwater. Test 6 catches this; the row turns up in the findings memo with a dollar figure attached.

Every test reduced to a single signed dollar figure against the midline, ranked by materiality. This is the page a CFO reads first. Two findings here — contract value integrity and cost estimate integrity — account for most of the exposure, which is the usual pattern.

The one-screen view a CFO opens on the third of the month. Nothing here is novel on its own — the difference is that every number has been tied back to the ledger before it was allowed onto the page.

Four deliverables, all of them yours to keep

📜

Findings Memo

Each finding structured identically: what was tested, what was found, dollar magnitude, root cause, whether it's a data problem or a process problem, who owns the fix, and effort to close. Ranked by materiality.

📊

WIP Reconciliation Workbook

The actual tie-out worksheets, so your controller can reproduce every number independently rather than taking our word for it. Most teams are still using this a year later.

🗺

Data Source Map

Which ERP object and field feeds which reported number, and every definitional decision it embeds — which account ranges are revenue, which book is authoritative, which date governs the period. Most contractors have never had this written down.

🎤

Readout & Build Proposal

Ninety minutes with your CFO and controller walking through the findings, followed by a fixed-fee build scope priced from what the audit actually surfaced. The audit fee credits fully toward that build if you proceed.

WIP reconciliation: common questions

Do you need access to our ERP system? +
Not necessarily. The audit can run entirely on flat exports your controller sends us, which usually means starting within three days. A read-only API or database user gives cleaner data but typically adds two to six weeks of security review, so most engagements begin with exports and add direct access later if there's a build.
What if everything reconciles cleanly? +
Then you receive documented confirmation that your WIP schedule ties to your ledger — which is itself worth having in front of a lender, a surety or an auditor. The engagement is framed like an audit opinion, so a clean result is a legitimate outcome rather than a failed engagement. We'd rather tell you your data is sound than manufacture a finding.
Does the audit fix the problems it finds? +
No, and that's deliberate. The audit diagnoses and quantifies. Remediation is separate work, and quoting it accurately requires having done the diagnosis first. Stating that boundary explicitly is what keeps the fee genuinely fixed rather than drifting into an open-ended cleanup.
How is this different from what our CPA already does? +
Your CPA audits whether the financial statements are fairly stated at a point in time. This examines whether the data flowing out of your ERP into your WIP schedule is structurally sound month over month, and why any variances arise. They're complementary. In practice, a clean reconciliation makes your CPA's job faster and cheaper.
What does it cost, and what happens if we want a build? +
Fixed fee, quoted after the free teardown once we've seen the shape of your WIP schedule and know the job count. The fee credits fully toward a warehouse and dashboard build if you proceed, so the audit functions as paid discovery rather than a separate purchase.
Are the dashboards on this page from real client work? +
No. Every figure shown above is synthetic, built on a fictional contractor for illustration. We don't publish client data, client names or client numbers — including anonymised. Client work stays confidential, and the only client material that ever appears on this site does so with written permission.
