When should a privately held company consider an internal-control review?

Internal Controls · Published August 3, 2026

A privately held company does not need to wait for a major loss or public failure before examining its internal controls. A review may be useful when the business has changed faster than its approval practices, access rights, documentation, or management oversight.

Internal controls are the responsibilities, approvals, system rules, records, and monitoring practices management uses to support business objectives. They are part of daily operations, not simply a policy manual. No control system eliminates risk, and a review does not take responsibility away from management. It gives management or a designated governance group a structured view of a selected process and what may deserve attention.

Signs that a review may be timely

Growth has outpaced the original process

A workflow designed for a smaller company may rely on informal approvals or one person’s knowledge. Added volume, employees, entities, locations, or product lines can make those practices harder to supervise. A review can compare the current process with the company’s present size and risk profile.

Important duties are concentrated

Risk can increase when one person can create a vendor, approve a purchase, release a payment, and reconcile the account—or perform several equivalent stages of another process. Smaller companies cannot always separate every duty. Management may instead need carefully designed approvals, access restrictions, exception reports, or independent review.

Systems or access have changed

A new accounting platform, payroll provider, billing system, acquisition, or automation may change who can initiate, approve, modify, and report transactions. A review can examine selected user roles, approval paths, data handoffs, and administrative access after the implementation has settled.

Exceptions keep recurring

Late reconciliations, duplicate payments, unexplained inventory adjustments, billing corrections, stale receivables, missing approvals, or recurring close entries may indicate that a process deserves attention. The objective is to understand the cause and the related controls, not merely clear the latest exception.

Outside expectations have increased

An owner, board, lender, investor, customer, or other stakeholder may ask for clearer information about selected controls. The review should begin with the exact question and intended audience rather than an undefined promise to “review everything.”

Known actions remain open

A prior review, system project, or management discussion may have identified improvements that were never completed or tested. Follow-up work can organize ownership and status while management decides and implements any corrective action.

A focused review can begin with one process

A privately held company may not need an enterprise-wide program. It can start with a defined area such as:

• Purchasing, vendor changes, and payments.
• Payroll setup and employee-change approvals.
• Billing, collections, credits, and cash application.
• Inventory movements and adjustments.
• The financial close and account reconciliations.
• User access, role changes, and administrative permissions.

A useful scope identifies the business objective, process boundaries, relevant locations or systems, management contact, intended audience, timing, and information available. That keeps the work aligned with the question management actually needs answered.

What an internal-control review may involve

A structured review generally moves through five stages:

1. Define the objective. Clarify the concern, selected process, relevant risks, reporting audience, and responsibilities.
2. Understand the workflow. Review policies and system information, speak with designated employees, and document how work is actually performed.
3. Examine selected evidence. Review the approvals, access records, transactions, reconciliations, or exceptions included in the agreed scope.
4. Discuss observations. Confirm relevant facts with management and communicate which items deserve attention.
5. Report and follow up. Provide observations and recommendations for management’s consideration and, if separately included, review the status of selected responses.

The scope may use concepts from established internal-control frameworks, but it should remain proportionate to the company and the question being examined.

What remains management’s responsibility

Management owns the processes and controls under review. It decides whether and how to respond to recommendations, approves changes, assigns resources, and remains responsible for implementing and operating corrective actions. The review does not determine whether fraud occurred, provide legal or regulatory conclusions, or guarantee that future errors or misconduct will be prevented.

Internal Audit serves management or a designated governance group through reviews of selected processes, risks, and controls. It is separate from an external financial-statement audit, which John W. Halloran CPA, P.C. does not perform.

How to prepare for a review

Before work begins, collect the current process narrative or policy, organization chart, role and access lists, approval limits, relevant system reports, recent reconciliations, examples of exceptions, and prior action plans. Identify the employees who understand each stage of the workflow. Management should also state what prompted the review and who will receive the report.

Incomplete documentation does not necessarily prevent a review. The gap between the written process and actual practice may itself be relevant. What matters is agreeing on the available information and the limits of the work.

A short decision test

A focused review may be worth considering if management answers yes to one or more of these questions:

• Has the business changed materially since the process was designed?
• Are important responsibilities concentrated without clear compensating controls?
• Do recurring exceptions suggest the process is not operating as intended?
• Has a system, location, entity, or key employee recently changed?
• Does management or governance need a documented view of a selected risk?
