How do you set up internal controls for the first time?

Start with the processes, not the controls. Identify the five to eight business processes that carry the most financial risk, document how each one actually runs today, and give each an owner. Only then design controls over them. Controls designed before the process is understood tend to protect the wrong thing.

Below is a practical checklist for scaling companies building a formal control environment for the first time. It is a starting point, not an extensive list of all necessary tasks.

Roles, Responsibilities and Access

Remove access to financial systems and physical assets from anyone whose role does not require it

Ensure no single employee has end-to-end control over a high-value transaction

Define a clear escalation path

Transaction Controls

For each high-risk process, design at least one preventive control and one detective control

Set documented approval thresholds for payments, purchases, and expenses

Require dual authorisation for payments above a defined threshold and for all payments to new payees

Require that adjustments above a defined threshold are reviewed and approved before posting

Close and Reconciliation

Define a standard month-end close checklist and calendar

Require monthly reconciliation of all bank accounts by someone who does not also process transactions

Set up formal balance sheet reconciliation of key accounts

Set up a standard review of accruals and prepayments before each month-end

Documentation and Monitoring

Write up each control in a short description

Compile all control descriptions into a single control register

Set up a simple exception log

Organise control approval records in a format that can easily be shared with auditors
