What changes when the audit goes PCAOB: the standards, the independence rules, the evidence bar, and how to prepare a company whose auditors are themselves being inspected.
We prepare your company for the audit the way the auditors will actually test it, because we have done that work ourselves.
PCAOB audit support for a first public-company audit
Key takeaways
What it is. The going-public audit specifics: the uplift-versus-re-audit decision that sets the filing timeline, the accounting areas that draw SEC comments, critical audit matters, and the cost drivers a company controls.
Where it breaks. The uplift-or-re-audit decision is the single biggest driver of time to filing, and the areas the staff comments on, revenue, estimates, segments, and cheap stock, delay filings when they are not documented first.
How we help. We scope the uplift first because it gates the clock, document the comment-prone areas before fieldwork, and reduce the fee with the preparation only the company can do.
A PCAOB audit is not an AICPA audit with a different cover page. The standards are the PCAOB’s own, the independence rules are the SEC’s and stricter, the auditors write differently structured reports, and, most consequentially for you, the audit firm is itself inspected on the quality of its work, which flows directly into how much evidence they demand from the company.
We prepare companies for these audits from the company’s side of the table, and our team has performed them at Big Four firms, including on some of the largest global consumer products, entertainment, and pharmaceutical issuers. The general phase-by-phase audit playbook lives on our audit support page; this page covers what is specifically PCAOB about the exercise.
The timeline driver
Uplift or re-audit: the decision that sets your filing timeline
Your registration statement needs the historical periods audited under PCAOB standards, and your existing audits usually were not. Whether those years can be uplifted (the incumbent, if PCAOB-registered and independent for those years, performs the incremental procedures and reissues) or must be re-audited (a successor firm audits the years from cold, with predecessor cooperation, workpaper access, and a reissued report and consent) is the single biggest driver of your time to filing. Emerging growth company status cuts the required years from three to two, sometimes the difference in whether uplift is feasible at all, so we scope this in week one.

Protecting the timeline
The accounting areas that draw SEC comments and delay a filing
Every SEC comment round costs calendar time, so the areas the staff comments on most are the ones to document before fieldwork, and it helps to know what each comment actually asks. Revenue recognition: principal versus agent, the measure of progress on over-time revenue, and variable consideration and its constraint. MD&A: quantify each driver of a material change and the offsetting factors, and disclose the known trends behind it. Non-GAAP measures and KPIs: undue prominence, individually tailored measures, and how each KPI is calculated. Estimates and fair value: the key assumptions and their sensitivity, reporting units with little impairment headroom, and Level 3 inputs. Segment reporting: how the chief operating decision maker runs the business, and the aggregation of operating segments. Stock compensation and cheap stock: pre-IPO grant valuations against the offer price. Income taxes: the rate reconciliation and the deferred-tax valuation allowance. For a non-EGC issuer these same judgment areas become critical audit matters under AS 3101, and a position documented before fieldwork closes a comment round instead of opening an amendment.
The recurring comment areas that push out a filing, and how documentation prevents it. Illustrative.
Cost
What a PCAOB audit costs, and the levers you control
A first PCAOB audit costs a meaningful premium to the old AICPA audit, and the drivers are structural: more required procedures (journal-entry and fraud testing under AS 2401, expanded related-party work, and mandatory control understanding even without a 404(b) opinion), a higher evidence bar driven by the firm’s own PCAOB inspection exposure, an engagement quality review before the opinion, and ICFR testing where the audit is integrated. The one lever a company controls is preparation: organized, tied-out PBC before fieldwork, position memos written ahead of time, and a journal-entry reconciliation that runs at close, which converts auditor hours from construction into review.

Our Experience
Where we have done this work
Engagement Notes
First PCAOB audits, scoped before they started
Company-side preparation for first public-company audits across IPO, reverse merger, and SPAC paths: uplift-versus-re-audit scoping in week one, opening balance sheet and equity history remediation, position memos delivered ahead of fieldwork, and JE population reconciliations built into the close so the fraud-procedure requests were exports, not projects.
Engagement Notes
Both sides of the table
Our team's Big Four background includes PCAOB audits of global consumer products, live entertainment, and pharmaceutical issuers, and current audit-firm roles alongside the advisory practice. The PBC packages we build for clients are shaped by having tested the other side's, which is why they tend to hold up when the engagement team tests them.
The Detail
The gaps, and how we close each one
Issue 01
AICPA versus PCAOB: what actually changesStandards
Companies stepping toward the public markets hear that their audits must become PCAOB audits and assume it is a formality. It is not: the applicable standards, the auditor’s obligations, the report itself, and the practical evidence bar all shift, and the shift is priced in both fees and hours.
The treatment
The audit is conducted under PCAOB auditing standards by a PCAOB-registered firm, layered with SEC and PCAOB independence rules that are stricter than the AICPA’s. Concretely, expect: deeper required work on internal control understanding even without an ICFR opinion, mandatory journal-entry testing and fraud procedures, expanded related-party and significant-unusual-transaction requirements, engagement quality review before the opinion, and an audit report that names tenure, Form AP disclosure of the engagement partner, and, for non-EGC issuers, critical audit matters. Behind all of it sits inspection: the PCAOB reviews the firm’s files, and deficiencies land on the firm, which is why requests that feel excessive are often the auditor evidencing against their own inspection risk. Budget the first PCAOB cycle at a meaningful premium to the AICPA audit in both cost and management time, and treat the evidence bar as the standard, not a negotiation.
What we do: We brief your team on what changes, budget the real premium, and build the evidence packages the standards demand.
Issue 02
The uplift versus re-audit decisionUplift vs Re-audit
A registration statement needs the historical periods audited under PCAOB standards, and your existing audits usually were not. Whether those years can be uplifted or must be re-audited, and by whom, is the single biggest driver of your timeline to filing.
The treatment
Three paths, in descending order of speed. If the incumbent firm is PCAOB-registered and performed quality AICPA audits, it can generally uplift: perform the incremental procedures PCAOB standards require for the already-audited periods and reissue under the right standards, the fastest route and the reason auditor selection years before an IPO matters. If the incumbent is not registered or not positioned to continue, a successor firm re-audits the required periods, a full audit of years whose closes are cold, with the timeline consequences that implies; predecessor cooperation, workpaper access, and, where any predecessor-audited period remains presented, the predecessor’s reissued report and consent become their own workstream. The third variable is period count: emerging growth company status cuts the required years from three to two, sometimes the difference between uplift and re-audit being feasible at all. We scope this decision in week one of any going-public engagement, because everything else schedules behind it.
What we do: We scope uplift versus re-audit in week one, including predecessor consent logistics, because everything schedules behind it.
From our engagements: The most expensive assumption in IPO planning is that existing audits are done. Clean AICPA opinions that cannot support a registration statement have restarted more timelines than any accounting issue we see, which is why the uplift-versus-re-audit scoping happens before anything else.
Issue 03
Auditor independence: the rules that reshape who does whatIndependence
SEC and PCAOB independence rules prohibit your auditors from doing work private-company firms did routinely: bookkeeping, valuation, financial statement preparation. Companies discover this when the auditor withdraws from helping, mid-engagement, and nobody is left holding the pen.
The treatment
The SEC’s independence rules prohibit the auditor from, among other things, bookkeeping, preparing the financial statements they audit, valuation services, and internal audit outsourcing for the audit client, with every permissible non-audit service requiring audit committee preapproval. Partner rotation applies on defined cycles, and independence reaches back: services the firm provided during the audit periods can impair independence retroactively, a diligence item when selecting the IPO auditor and a problem when the friendly local firm that kept the books wants to become the registered auditor of those same books. The practical consequence is structural: someone independent of the audit firm must prepare the statements, the memos, and the schedules the auditors test, which is the company-side preparation we handle. We also run the preapproval hygiene, the service inventory, the audit committee calendar, the fee disclosure, so independence is a documented state rather than an assumption.
What we do: We do the preparation the rules require, and run the preapproval and service-inventory hygiene for the audit committee.

Controls in the audit: integrated or not, they are in scopeAS 2201 / 2110
Teams equate control work with 404(b) and assume a financial-statement-only audit ignores controls. PCAOB standards say otherwise: the auditors must understand your controls regardless, and what they find shapes the entire substantive strategy, and the deficiency letter you receive either way.
The treatment
In an integrated audit (required when 404(b) attestation applies), the auditor opines on ICFR under AS 2201: walkthroughs, control testing at the assertion level, and a top-down risk approach that mirrors the management program on our SOX page. In a financial-statement-only audit, the auditor still must obtain an understanding of internal control sufficient to assess risk, walk through significant processes, and evaluate control deficiencies they observe, and without tested controls they cannot rely on them, so the audit goes substantive-heavy: bigger samples, more confirmations, more year-end work, which is a cost you pay in fees and year-end overtime. Either way, deficiencies get communicated, and material weaknesses disclosed in a registration statement are priced by investors. The company-side move is the same in both worlds: a documented close, key reports validated, and reconciliations that work, because control quality sets the audit’s tone even when nobody opines on it.
What we do: We harden the close and validate the key reports so control quality helps the audit whether or not anyone opines on it.
Issue 05
Critical audit matters: the report section you should see comingAS 3101
For non-EGC issuers, the auditor’s report now narrates the hardest parts of your audit: critical audit matters, named, described, and tied to your disclosures. Companies that first read their CAMs in the draft report a week before filing have ceded the framing of their own judgment areas.
The treatment
A CAM under AS 3101 is a matter communicated to the audit committee that relates to material accounts or disclosures and involved especially challenging, subjective, or complex auditor judgment, in practice, revenue recognition judgments, business combination valuations, impairment, complex instruments, and heavy estimates. EGCs are exempt, one of the less obvious benefits of the status. You cannot veto a CAM, but you can prepare for it: know from the audit plan which areas are candidates, ensure the related footnote and MD&A disclosure is robust enough that the CAM description references your disclosure rather than substituting for it, and see the draft language early through the audit committee process so the description is accurate. A CAM on a well-documented judgment reads as rigor; a CAM describing procedures around thin disclosure reads as a flag. The position memos we write are, among other things, CAM preparation: the better the company’s documentation, the more the CAM narrates your framework instead of the auditor’s struggle.
What we do: We strengthen the disclosure behind each CAM candidate and get draft language in front of the audit committee early.
Issue 06
Inspection-driven focus areas: what the auditors will over-test, and whyInspection Focus
PCAOB inspection findings shape audit programs a year later: whatever the Board faulted firms for, your auditors will evidence hard this cycle. Companies experience this as escalating requests in the same few areas and mistake it for the engagement team being difficult.
The treatment
The persistent inspection themes map directly to the requests you should pre-build for: revenue recognition (contract-level testing, cutoff, the estimates inside variable consideration), estimates and fair value (impairments, valuations, allowance models, with the auditor obligated to test data, methods, and assumptions), journal entries (population completeness for the fraud-focused JE testing, which means your ledger extract has to reconcile to the statements to the dollar), related parties and significant unusual transactions, and ICFR testing depth where integrated. The efficient response is to treat these as standing PBC categories: contract packages assembled at signing, estimate files with inputs sourced and sensitivity shown, a JE population reconciliation that runs at close, and a related-party inventory maintained continuously. Auditors under inspection pressure do not need less evidence from you; they need it organized, and the companies that internalize that stop experiencing PCAOB audits as adversarial.
What we do: We pre-build the standing PBC categories, contracts, estimate files, JE reconciliation, related parties, before the requests arrive.
FAQ
Frequently asked questions
Our current auditor is PCAOB-registered. Are we set?
Registration is necessary, not sufficient. The question is whether the firm can uplift the historical periods to PCAOB standards, meets the SEC independence rules for those periods (including any bookkeeping or preparation services they provided), and has the issuer-audit capacity for your timeline. We scope all three before assuming the incumbent carries you through.
Why does the PCAOB audit cost so much more than our old audit?
More required procedures (JE testing, related parties, control understanding), a higher evidence bar driven by the firm's own inspection exposure, engagement quality review, and, where integrated, ICFR testing. The company-side lever is preparation: organized evidence converts auditor hours into review instead of construction.
Can our auditors help us prepare the financial statements they audit?
No. SEC independence rules prohibit the auditor from bookkeeping and from preparing the statements and records they audit, which is precisely why company-side preparation exists as a discipline. We prepare; they test. The roles cannot blur without impairing the audit.
Do critical audit matters apply to us?
Not if you are an emerging growth company; CAMs are required for other issuers' audits. If they apply, the practical move is early sight of candidate areas and draft language through the audit committee, and disclosure strong enough that the CAM points to it.
What should we build before our first PCAOB fieldwork?
Five things: a reconciled opening balance sheet and equity history, position memos on every judgment area, a JE population that ties to the statements, estimate files with sourced inputs, and a related-party inventory. That set addresses the inspection-driven request patterns before they become findings.
