THE PROCESSWhere we end and your auditor begins

We verify your readiness. Your auditor performs the audit.

Auditus.ai is audit-readiness software. We help you verify that the minimum required documents are in place for an auditor to do their work — nothing more. We do not perform audit activities, issue opinions, or test internal controls. Once your readiness package is complete, your audit firm takes over and produces the deliverables listed below.

Four stages, two responsibilities

1You (the issuer)

Gather your documents

Trial balances, GL extracts, supporting memos, contracts, audit-committee minutes, ICFR documentation, prior-year audit papers — whatever applies to your situation.

2Auditus.ai (us)

Verify your readiness package is complete

We check your uploaded files against the minimum required documents for your audit purpose, jurisdiction, framework, industry, and cross-listing status. We tell you what's missing. We do not assess controls, issue opinions, or perform audit procedures.

3Your audit firm

Performs the audit

Risk assessment, walkthroughs, substantive testing, journal-entry testing, confirmations, sample selection, control testing — all governed by CAS, IFRS, NI, and CPAB. Audit firms are CPAB-registered (Canada) or PCAOB-registered (US-listed).

4Your audit firm

Produces the audit deliverables

Audit report, management letter, audit-committee communication, rep letter, ICFR communication, and — where applicable — comfort letter, consent, carve-out report, closing-balance-sheet audit. Each is listed in detail below.

What Auditus.ai does — and doesn't do

WE DO
  • Verify your minimum required documents are uploaded
  • Tell you which required documents are missing
  • Tailor the checklist to your purpose, jurisdiction, industry, framework
  • Cite the standard that requires each document
  • Explain what your auditor will produce next
WE DON'T DO
  • Issue audit opinions on financial statements
  • Test the operating effectiveness of internal controls
  • Perform risk assessment, walkthroughs, or substantive testing
  • Provide assurance of any kind under CAS, ISA, or PCAOB AS
  • Replace or compete with your audit firm
WHAT YOUR AUDITOR PRODUCES

Every deliverable, with descriptor and purpose.

These are the deliverables your audit firm produces — not Auditus.ai. Each is mapped to the standard that requires it, with a plain-English description of what it is, why it matters, and when in the audit cycle it lands.

Engagement letter

CAS 210
What it is

Signed agreement between the audit firm and the issuer setting out the scope, responsibilities, timeline, and fee for the audit.

Why it matters

Required before any audit work starts. Defines what the audit firm will and will not do — so there are no surprises later.

When: At engagement acceptance (before fieldwork)·All purposes

Audit report (opinion on the financial statements)

CAS 700
What it is

The signed report stating whether the financial statements present fairly, in all material respects, the issuer's financial position and results — under IFRS, US GAAP, or ASPE as applicable.

Why it matters

The deliverable. This is what the public market, the audit committee, lenders, and investors rely on to trust the financial statements.

When: At the close of the audit (signed alongside the F/S)·All purposes

Management letter (significant deficiencies)

CAS 265
What it is

A written communication from the audit firm to those charged with governance, identifying significant deficiencies in internal control discovered during the audit.

Why it matters

Forces the issuer's board and audit committee to see and address control gaps. Carries forward year-over-year if not remediated.

When: Shortly after the audit report is signed·All purposes

Audit committee communication (key audit matters)

CAS 260, CAS 701
What it is

Formal communication to the audit committee covering the planned scope and timing of the audit, significant findings, key audit matters, and any independence concerns.

Why it matters

Required by CAS 260; this is how the audit committee discharges its oversight role over the audit.

When: Planning phase, then at completion·All purposes

Management representation letter

CAS 580
What it is

A signed letter from management to the audit firm asserting that the F/S are complete, that all material transactions are recorded, that management has disclosed all relevant information, and other specific representations.

Why it matters

The audit firm needs this on file before signing the audit report. Without it, the report cannot be issued.

When: Dated the same date as the audit report·All purposes

Going-concern conclusion memo

CAS 570, IAS 1
What it is

The audit firm's documented conclusion on management's going-concern assessment — whether the issuer can continue operations for at least 12 months from the report date.

Why it matters

If the auditor concludes there's material uncertainty, the audit report includes an emphasis-of-matter paragraph that is a major signal to investors and lenders.

When: At the close of the audit·All purposes

ICFR communication (NI 52-109 context)

NI 52-109, CAS 315
What it is

The audit firm's documented assessment of the design and operating effectiveness of the issuer's internal control over financial reporting, supporting management's NI 52-109 certifications.

Why it matters

Reporting issuers' CEO and CFO sign NI 52-109 certifications. The audit firm's ICFR work-product is what supports those certifications under inspection.

When: Annual audit cycle·Annual auditGoing public

SOX 404(b) ICFR auditor attestation (US cross-listed only)

SOX 404(b)
What it is

A separate signed attestation by the audit firm on the effectiveness of the issuer's ICFR, required for US-listed large accelerated filers.

Why it matters

Without it, a 10-K or 40-F cannot be signed by a large accelerated filer.

When: Annual filing with SEC·Annual audit

Comfort letter (to the underwriter)

NI 41-101; AU-C 920 (US)
What it is

A signed letter from the audit firm to the underwriter providing negative assurance on specified financial information in the prospectus.

Why it matters

The underwriter relies on this letter for its due-diligence defence. No comfort letter, no pricing call.

When: Pricing date of the IPO·Going public

Auditor consent (to inclusion of the audit report in the prospectus)

NI 41-101 §4A.5
What it is

A signed, dated consent allowing the audit report to be reproduced in the prospectus filing.

Why it matters

Without it, the prospectus filing is rejected on receipt by the securities commission.

When: Just before prospectus filing·Going public

Opening-balance communication (new auditor only)

CAS 510
What it is

When the audit firm is new to the issuer this year, a documented assessment of opening balances — either via review of the predecessor auditor's working papers or by performing alternative procedures.

Why it matters

Without this, the audit firm cannot issue an unqualified opinion on the comparative period.

When: Early in the audit cycle·All purposes

Carve-out audit report (for the part of the business being sold)

CAS 700
What it is

A separate audit report on the financial statements of a divested business unit, prepared on a stand-alone basis using management's allocation methodology for shared costs and capital.

Why it matters

The buyer needs an audited basis for the business they are acquiring. Without it, the working-capital true-up and purchase-price adjustments cannot be calculated.

When: Pre-closing of the transaction·Sale of company

Closing balance sheet audit + working-capital true-up letter

CAS 700; transaction-specific
What it is

An audit of the balance sheet as at the closing date of the M&A transaction, plus a letter quantifying the working-capital adjustment against the agreed peg.

Why it matters

Triggers the dollar-for-dollar purchase-price adjustment that releases (or claws back) the closing escrow.

When: Within 60–90 days post-closing·Sale of company

Audited base-period financial statements (for the valuator)

CAS 700
What it is

Audited financial statements covering the period that the valuator will use as the historical base for their DCF or multiples analysis.

Why it matters

A valuation built on un-audited numbers is not defensible in litigation or against IRS / CRA challenge. The audit firm's deliverable anchors the valuator's work.

When: Before the valuator finalizes the report·Valuation
