Internal controls for growing businesses

Internal controls are the processes that protect your business from fraud, errors, and inefficiencies. They do not require bureaucracy—just thoughtful design.

The Basics: Segregation of Duties

The same person should not authorise a transaction AND process it, handle cash AND record it, or create a vendor AND approve payments to them.

In small teams, this is challenging. Focus on high-risk areas first.

Key Control Areas

Cash and Banking: Bank reconciliation by someone who does not handle cash, dual signatures for payments above threshold, regular review of bank statements by owner/director, and petty cash imprest system with regular counts.

Purchases and Payments: Approved vendor list, purchase orders for transactions above threshold, three-way match of PO, receipt, and invoice, and payment approval separate from payment processing.

Sales and Receivables: Credit limits approved before sales, invoicing independent of delivery where possible, regular customer ledger reconciliation, and collections tracking with escalation process.

Payroll: New hire approval before payroll setup, payroll changes reviewed before processing, ghost employee checks periodically, and attendance/time records reviewed.

Practical Implementation

Start with bank reconciliation by someone other than bookkeeper, payment approval for amounts above ₹10,000, physical inventory counts quarterly at minimum, and review of customer ageing by owner/director.

Add as you grow: formal vendor approval process, purchase order system, internal audit function, and exception reporting with review.

Warning Signs of Control Weakness

Cash shortfalls with explanations, vendor complaints about payments not received, customer complaints about deliveries not made, missing documentation, and resistance to audits or questions.

The Balance

Controls should enable business, not paralyse it. Design for risk by focusing controls on high-value, high-risk areas. Design for practicality with controls that people will actually follow. Consider cost-benefit by not spending ₹100 to prevent ₹10 loss.

If controls exist only on paper, the next useful step is usually Internal Audit, followed by practical SOP Development and process-backed execution through Accounting & Bookkeeping.
