SOX-aligned control testing, risk assessment, and audit-readiness documentation that gets you through lender and investor due diligence — without the cost of a full internal audit department.

Why SMEs Need Internal Audit (Without the Cost)

Lenders and investors no longer take your word for it. Before a commercial refinance, an SBA loan renewal, or an equity round closes, they want documented evidence that your controls actually work — not just a clean-looking balance sheet.

Building that capability in-house is expensive. A dedicated internal audit hire runs $80,000–$150,000+ a year once you add benefits, tools, and management overhead — a hard number to justify for a business that only needs formal testing once or twice a year. Outsourcing gets you the same rigor at transparent hourly rates, scaled to the work that actually needs doing.

Most controllers are already stretched managing close, AP/AR, and payroll. Testing your own controls objectively isn't just a time problem — it's a skills problem. Internal audit is a distinct discipline: risk assessment, sampling methodology, and documentation standards that auditors and lenders recognize.

Skip it, and the gaps surface at the worst possible moment. A due diligence team that finds undocumented approval workflows or unreconciled accounts doesn't just ask questions — it delays closing, or it re-prices the deal.

What We Test: SOX-Aligned Internal Control Assessment

Where are your controls actually documented, and where are they just assumed? We test four control layers and hand you evidence for each.

Operational Controls

Segregation of duties across AP/AR, payment approval workflows, and reconciliation procedures — the controls auditors check first because they're the easiest to break.

Financial Controls

Bank reconciliation timeliness, general ledger reconciliation, and journal entry review processes tested against your actual monthly close cadence.

See bank reconciliation pricing

Compliance Controls

Payroll tax filing accuracy, benefits administration, and regulatory documentation reviewed for gaps that surface in payroll or tax audits.

Technology Controls

User access and change management in QuickBooks, Xero, NetSuite, or SAP, plus data integrity checks on payroll systems.

Documentation and Evidence

We flag control weaknesses and hand you a remediation roadmap before a lender's diligence team or your year-end auditor ever sees the gap.

How We Deliver: Lean, Risk-Focused Engagement

Risk Assessment First
We prioritize high-impact areas — cash, revenue, payroll — instead of testing every process with equal weight. This keeps the engagement lean and the findings relevant.
Lean Six Sigma Documentation
We map processes, identify bottlenecks and control weaknesses side by side, and recommend efficiency fixes alongside compliance corrections — not just a list of problems.
Collaborative Testing
Your team supplies evidence — bank statements, AP registers, payroll reports. We validate it, sample it, and document the results in auditor-ready format.
Remediation Support
We don't hand you a findings report and disappear. We work alongside your team to implement corrective actions before your external auditor or lender arrives.

Who Needs This: Controllers Facing Lender or Investor Scrutiny

This service fits controllers in a specific position — check which apply to you:

Preparing for SBA lending or a commercial refinance where the lender requests evidence of internal controls
Facing due diligence from equity investors or an acquirer who will review control workpapers, not just financial statements
Heading into a year-end external audit and want to reduce audit scope and fees by documenting controls in advance
Running a multi-entity or multi-location business where headquarters needs assurance of branch-level financial integrity
Managing finance without a dedicated internal audit function, and needing third-party validation to back your reporting to leadership

If two or more of these apply, undocumented controls are a live risk to your next financing round or audit timeline.

Flexible Engagement Models

Internal audit needs shift with your financing timeline. Pick the model that matches where you are.

Fully Managed Model

We own the entire internal audit scope — planning, risk assessment, testing, evidence collection, and reporting — on a monthly or project retainer. Best when you need a complete, audit-ready package without pulling internal resources.

Staff Augmentation

Your team defines the scope; we embed a dedicated offshore accountant or audit specialist to execute testing under your direction. Best when you already have an audit plan and need execution capacity.

See dedicated staffing options

Hybrid

We perform risk assessment and high-risk area testing; your team handles lower-risk control validation using our templates and oversight. Best for controllers who want to keep some testing in-house.

Accurate Books. Timely Reports.

Internal controls aren't a compliance checkbox — they're what makes your financial reporting reliable in the first place. When a lender or investor reviews your books, documented controls are the difference between a fast close and a stalled one.

We deliver the workpapers, the risk matrix, and the remediation plan so you walk into due diligence with evidence, not explanations. Accurate books. Timely reports.

Frequently Asked Questions

What is SOX compliance and do I need it for my business?

SOX (the Sarbanes-Oxley Act) requires publicly traded US companies to document and test internal financial controls. Most private SMEs aren't legally required to comply, but lenders, private equity investors, and acquirers increasingly expect SOX-aligned control documentation as evidence of financial discipline — even without a formal legal mandate. If you're preparing for a refinance, equity round, or acquisition, testing controls to SOX standards strengthens your position even if full compliance isn't required.

How much does outsourced internal audit cost for a small business?

Costs depend on the scope of controls tested and the size of your transaction volume, but outsourced engagements run at transparent hourly rates starting from $7.5 to $20 per hour, far below the $80,000–$150,000+ annual cost of hiring a dedicated internal audit function. A focused engagement — for example, testing AP/AR and payroll controls ahead of a lender review — typically costs a fraction of a full-time hire's annual salary.

What's the difference between internal audit and external audit?

Internal audit tests and documents whether your controls and processes work as designed, and it's typically performed on your behalf, before problems surface. External audit is performed by an independent CPA firm to give an opinion on your financial statements, usually for regulatory or investor purposes. Well-documented internal audit work directly reduces the scope, time, and fees of your external audit because the auditor has less to test from scratch.

Can outsourced accountants perform internal control testing?

Yes. Internal control testing doesn't require an in-house employee — it requires accounting professionals trained in risk assessment, sampling, and documentation standards. An outsourced team can review segregation of duties, reconciliation timeliness, and payroll tax compliance with the same rigor as an internal hire, and often with more direct audit experience across multiple industries.

How long does an internal audit take?

A focused risk-based internal audit covering AP/AR, payroll, and reconciliation controls typically takes 3 to 6 weeks, depending on how much documentation already exists and how many locations or entities are in scope. A full multi-entity control assessment can take longer. Risk-based scoping — testing high-impact areas first — keeps most engagements on the shorter end.

What control weaknesses do lenders care about most?

Lenders and due diligence teams focus first on cash controls (bank reconciliation timeliness and approval workflows), segregation of duties in AP/AR, and payroll tax compliance. Weaknesses here signal broader risk because they touch the accounts most exposed to error or misstatement. Undocumented journal entry review and inconsistent user access controls in your accounting system are the next most common findings.
