Build the controls before the S-1

Controls, approvals and AI oversight that scale from Series B to the first SOX certification.

Growth outruns the approval matrix

At Series B the finance team is often a controller, a senior accountant and an outsourced payroll provider. By the late stages it runs a multi-entity close, revenue contracts with custom terms, equity compensation for hundreds of people and a stack of tools that each hold some piece of the approval chain. Controls that were adequate at $10M of revenue are rarely documented, often bypassed and almost never tested.

The public-company rules arrive in sequence. The CEO and CFO certify the first periodic report after the IPO, usually a quarterly report. Management's assessment of internal control over financial reporting follows with the second annual report. Auditor attestation depends on filer status, and the SEC proposed changes to those categories in May 2026. A material weakness identified during registration is normally disclosed in the registration statement, and it is far easier to fix before drafting starts than during it.

AI tools are now part of the close at many growth-stage companies, coding invoices, drafting reconciliations and preparing flux commentary. Each one acts through an account with permissions, and an auditor testing access will treat that account like any other user.

Four pressures before the filing

  • Boards and investors ask harder questions

    Later-stage investors and new independent directors expect an audit committee, a delegation-of-authority matrix and evidence that management reviews actually happen.

  • Small teams hold conflicting access

    The person who sets up vendors can often approve and pay them. In a lean team that is normal; without a compensating control, it is a deficiency.

  • Integrations and agents act unseen

    AP automation, close tools and AI agents run under service accounts that are rarely included in user access reviews.

  • Readiness competes with the S-1

    Documenting processes, closing design gaps and running a dry year of testing all need time from the same people preparing the registration statement.

Rule or standardWhat it asksStatus
Sarbanes-Oxley section 302The CEO and CFO certify each quarterly and annual report, including their conclusions on disclosure controls and procedures.Applies from the first periodic report filed after the IPO.
Sarbanes-Oxley section 404(a)Management's annual assessment of internal control over financial reporting, against a recognized framework such as COSO 2013.Required from the second annual report after the IPO, under the SEC's transition rule for newly public companies.
Sarbanes-Oxley section 404(b)The external auditor's attestation on internal control over financial reporting.Required for accelerated and large accelerated filers. Emerging growth companies are exempt while that status lasts, at most to the last day of the fiscal year following the IPO's fifth anniversary.
SEC filer-status proposal (19 May 2026)Would raise the large-accelerated-filer threshold to $2bn of public float and treat other filers as non-accelerated, without 404(b) auditor attestation.Proposed, not final, as of November 2026. The 404(a) management assessment would remain.

Work sized for a growing team

  • SOX & ICFR Readiness

    A gap assessment, process narratives, a risk and control matrix and a dry run of testing, timed to your filing.

  • Segregation of Duties & Approval Design

    An approval and access design that fits a small team, with compensating controls where splitting duties is not realistic.

  • AI Governance for Finance

    An inventory of AI tools and agents in finance, with permissions, approval thresholds and logging an auditor can test.

  • Continuous Controls Monitoring

    Automated weekly tests on journal entries, vendor changes and access, so exceptions surface before quarter end.

  • Board & Governance Review

    Committee charters, a delegation-of-authority matrix and a board financial pack ready for independent directors.

  • Code of Conduct & Speak-Up Programs

    A code of conduct and an accounting-complaints channel, both expected of listed companies, that employees will actually use.

Readiness starts with system access

The first SOX question an auditor asks is often simple: who can do what in the accounting system, and who checks? In a growth-stage company the answer usually includes a controller with administrator rights, an AP lead who can create and pay vendors, and several integration accounts nobody has reviewed since implementation. Mapping that access, then deciding which conflicts to remove and which to cover with a review, is the right first piece of SOX work because every later control depends on it. The Segregation-of-Duties Conflict Finder is a quick way to see the pattern in your own team.

Readiness runs in four steps

  1. Trace the processes that feed the financial statements. Revenue, purchase to pay, payroll and equity, treasury, the close and IT general controls.
  2. Test what exists against the ledger. A full-population scan of journal entries and approvals comes before any process narrative is written.
  3. Fix design gaps first. Start with access and approvals, because testing a badly designed control only documents the problem.
  4. Run a dry year of testing. Keep evidence your auditor can reperform, and fix what fails before it counts.

Our SOX & ICFR Readiness work follows this sequence and hands the program to your team, with a runbook for each control owner.

Agents count as users too

An AI agent that codes invoices or posts accruals acts through an account with permissions. If that account can also approve, the approval control is gone, however accurate the agent is. We inventory AI tools and agents in finance, place each one in the segregation-of-duties matrix, set human approval thresholds and make sure every action leaves a log you keep as long as the transaction records.

The illustrative scenario The agent that approved itself shows how this goes wrong at a Series C company and how it is fixed. Before AI agents run your close sets out the controls worth putting in writing first.

What people ask before hiring us

When should a venture-backed company start SOX work?

Earlier than the IPO timeline usually suggests. A practical sequence is a gap assessment about a year before the target filing, design fixes over the following two quarters, then a dry run of testing before the first annual report. Access and approvals come first, because most other controls depend on them.

Why not ask our audit firm to design the controls?

Auditor independence rules limit how much your audit firm can help design the controls it will later evaluate. That is why readiness work usually sits with management and an outside adviser. Finance Ethics does no audit or attest work, so it can work alongside your auditors without that conflict.

Does the SEC's May 2026 proposal mean we can skip 404?

No. As of November 2026 the proposal is not final. Even if adopted as proposed, management's 404(a) assessment and the section 302 certifications would remain. It would change who needs an auditor's 404(b) attestation, not whether management must assess its controls.

We use AI agents in AP and the close. Is that a SOX problem?

Not by itself. It becomes one when an agent's account can both prepare and approve, when its actions are not logged, or when no person reviews its output above a set threshold. Each of those can be designed out before your auditors test access.
