PCAOB-Registered Public Accounting Firm · United States
Public-company audits, done right.
PCAOB-Registered Audit Firm · 20+ Years of Audit Experience Across the Americas
Asesoria Global — also known as SESGLO — is a PCAOB-registered public accounting firm auditing SEC registrants, foreign private issuers, IPO candidates, and reverse-merger companies. Engagements are performed under PCAOB Auditing Standards (AS) and, for non-issuer audits, U.S. Generally Accepted Auditing Standards (GAAS). Partner-led, fixed-fee, and inspection-ready by default.
Small-cap issuers keep getting the wrong audit firm.
The Big Four won't prioritize a $20M-cap issuer, and many mid-tier firms haven't kept pace with the PCAOB's inspection expectations. The result: cost overruns, restatements, and comment letters. We built our U.S. audit practice (SESGLO) to be the opposite — senior-led, fixed-fee, and inspection-ready by design.
Partner on every engagement
The signing partner is in every planning meeting, every risk assessment, and every review note. No handing off to a first-year associate.
Inspection-ready workpapers
We document to AS 1215 discipline from day one, so your audit file stands up to PCAOB inspection without last-minute rework.
Fixed fees, known upfront
You get a written scope, a week-by-week timeline, and a fixed fee before we start. No change-order surprises at year-end close.
Integrated audits of Form 10-K and Form 20-F filings, plus quarterly interim reviews (AS 4105) of Form 10-Q. We plan the annual cadence so nothing slips into amendment territory.
Two-year comparative audits for Form S-1, Super 8-K, and Form 10 filings. Coordinated with your SEC counsel, underwriter, and investor-relations team so the filing timeline holds.
A four-phase audit built around your SEC calendar.
Every engagement starts with risk assessment and ends with an audit file ready for PCAOB inspection — not the other way around.
01
Scoping & independence clearance
We run independence checks under SEC Rule 2-01 and PCAOB Rule 3520, scope the engagement, agree on fee and timeline, and issue the engagement letter — all before any fieldwork begins.
02
Risk assessment & planning
We document risks of material misstatement at the assertion level, identify significant accounts and fraud risks, and walk through ICFR at the process level (AS 2110, AS 2201 when 404(b) applies).
03
Fieldwork & testing
Substantive testing, controls testing where applicable, and review of consolidation and tax provisions. Weekly status calls with the CFO, controller, and SEC counsel so there are no surprises at reporting.
04
Issuance & filing support
Engagement quality review (AS 1220), audit report issuance, consent for the SEC filing, and support through the SEC comment-letter process if one arrives.
Why issuers choose us
Built for the issuers the Big Four ignore.
PCAOB-registered
Registered under Section 102 of the Sarbanes-Oxley Act. All public-company engagements conducted under PCAOB Auditing Standards.

U.S. nationwide coverage
We serve issuers headquartered in any U.S. state and foreign private issuers with U.S. operations — remote-first execution, on-site when the engagement requires it.
Tight communication
Weekly status calls, a shared audit PBC tracker, and direct partner access. Your CFO doesn't chase us — we chase the PBCs.
Transparent fees
Fixed fee, written scope, written out-of-scope policy. If something material changes mid-engagement, we tell you — we don't invoice you and hope.
Frequently asked questions
What issuers and CFOs ask before engaging.
What is a PCAOB-registered audit firm?
A PCAOB-registered public accounting firm is an audit firm registered with the Public Company Accounting Oversight Board under Section 102 of the Sarbanes-Oxley Act of 2002. Only PCAOB-registered firms may prepare or issue audit reports for U.S. public companies (SEC issuers), brokers and dealers, and foreign private issuers that file with the SEC. Asesoria Global (SESGLO) is registered with the PCAOB and conducts all public-company engagements under PCAOB Auditing Standards.
Does my company need a PCAOB auditor?
Yes if you file audited financial statements with the SEC. That includes companies listed on NYSE, Nasdaq, NYSE American, OTCQX, OTCQB, companies filing Form 10-K / 10-Q / 20-F / 8-K with audited financials, companies in an IPO (Form S-1) or reverse merger (Form 10), and SEC-registered broker-dealers. Private companies with no SEC filing obligation do not need a PCAOB auditor.
What is the difference between PCAOB and GAAS/AICPA audits?
A PCAOB audit is conducted under PCAOB Auditing Standards (AS) and is required for SEC issuers. A GAAS/AICPA audit is conducted under Generally Accepted Auditing Standards issued by the AICPA Auditing Standards Board and is used by non-SEC entities. PCAOB audits have stricter independence rules, mandatory PCAOB inspections, and more prescriptive documentation requirements (AS 1215).
Can a PCAOB-registered firm audit foreign private issuers (FPIs)?
Yes. FPIs listing on a U.S. exchange file Form 20-F and must be audited by a PCAOB-registered firm. FPIs may file under IFRS as issued by the IASB (no U.S. GAAP reconciliation required) or under U.S. GAAP. Asesoria Global (SESGLO) audits FPIs from Latin America and other regions with bilingual engagement teams and technical competence in both IFRS and US GAAP.
How long does a first-time PCAOB audit take?
A first-time PCAOB audit typically runs 12 to 20 weeks from kickoff to report issuance, depending on company complexity and quality of underlying records. IPO readiness engagements (two comparative years under S-X Rule 3-01) usually run 16 to 24 weeks. You receive a fixed fee and a week-by-week timeline before engagement acceptance.
What is SOX Section 404 and does it apply to my company?
Sarbanes-Oxley Section 404(a) requires management to assess ICFR (applies to all SEC registrants). Section 404(b) requires an independent auditor's opinion on ICFR and applies to accelerated and large accelerated filers (public float above $75M). SRCs, EGCs during the JOBS Act five-year exemption, and non-accelerated filers are typically exempt from 404(b).
Do you audit OTC-listed companies?
Yes — we audit companies on OTCQX, OTCQB, and OTC Pink Current Information tier when they file with the SEC or are required to provide PCAOB-audited financials for tier qualification. We also support OTC-to-Nasdaq uplisting, including ICFR remediation and comparative-period re-audits.
What happens if the SEC issues a comment letter?
SEC comment letters on audited financial statements are included within scope at no additional fee when the comment relates to our audit work product. Drafting of management's response is coordinated with your SEC counsel. We track the comment-letter process to full resolution and withdrawal of comments.
