Internal control is a fundamental pillar in risk management and ensuring transparency within an organization. When implemented effectively, it not only prevents fraud and errors, but also strengthens stakeholder confidence and improves operational efficiency.
In this article, we will analyze a real case of successful internal control (without confidential details) to extract key lessons and best practices that can be applied in other organizations. This example demonstrates how a well-designed control structure can transform risk management and generate value for the company.
The Challenge: Risks in Supplier Management
A large company in the industrial sector with international operations faced significant challenges in supplier management. The organization depended on an extensive network of suppliers for the acquisition of key inputs, but the internal controls were deficient, which generated risks such as:
- Duplicate payments and billing errors.
- Lack of transparency in supplier selection.
- Risk of fraud and conflict of interest.
- Delays in delivery and quality problems.
Senior management requested an internal audit to evaluate the internal controls in the process of contracting and payments to suppliers. The internal auditors identified significant weaknesses and proposed improvements to strengthen internal control.
The Solution: Implementation of an Effective Internal Control Framework
- Strengthening the Approval and Authorization Process
Before the audit, the organization lacked a clear approval flow for the selection and payment of suppliers. As a result, the following controls were implemented:
- Creation of a supplier selection committee to ensure transparency in contracting.
- Use of a double approval system for the authorization of payments.
- Validation of contracts and terms of service before any financial commitment.
These changes reduced the risks of corruption and conflict of interest, in addition to improving the quality of the contracted suppliers.
- Implementation of Technology and Automation
One of the biggest problems detected was the lack of integration between the purchasing and accounting systems. To address this, the company invested in:
- An ERP (Enterprise Resource Planning) system that connected purchases, accounting, and payments.
- Automation of controls to detect duplicate invoices.
- Real-time alerts to detect payments outside of approved contracts.
With these improvements, the company reduced billing errors by 40% and achieved greater efficiency in payment processes.
- Creation of a Supplier Registry with Risk Assessment
Before the audit, the company had no formal criteria for evaluating its suppliers. As part of the solution, it was established:
- A single supplier registry with verified and updated information.
- Classification of suppliers by level of financial, operational, and compliance risk.
- Continuous performance monitoring to evaluate quality and compliance with contracts.
This system allowed the company to reduce dependence on unreliable suppliers and improve the quality of the products and services acquired.
- Periodic Internal Audits and Compliance Culture
To ensure the sustainability of internal control, new internal audit policies were established:
- Periodic audits of the purchasing and payment process.
- Training of personnel in internal controls and risk management.
- Anonymous reporting channels to report irregularities.
These actions strengthened the organizational culture and generated greater confidence in supplier management.
Results of the Success Case
After the implementation of these controls, the company achieved measurable results in less than a year:
✅ 40% reduction in billing errors and duplicate payments.
✅ Greater transparency in supplier selection.
✅ Decrease in internal fraud related to suppliers.
✅ Significant savings in operating costs.
✅ Greater confidence on the part of regulators and external auditors.
The combination of structured processes, technology, internal audit, and compliance culture allowed the company to turn a high-risk area into an example of efficiency and transparency.
Lessons Learned and Good Practices
This success case leaves valuable lessons that can be applied in any organization:
1️⃣ Internal controls must evolve over time.
The company detected risks due to obsolete processes and updated its controls to align with best practices.
2️⃣ Technology is key for efficiency and error prevention.
The implementation of an ERP and automation systems helped to detect duplicate payments and improve traceability.
3️⃣ Internal audit should be a strategic partner of the business.
Beyond pointing out failures, the internal audit function provided concrete solutions and helped strengthen risk management.
4️⃣ Continuous monitoring and supervision are essential.
It is not enough to establish controls only once. Periodic audits and supplier monitoring guaranteed the success of the new system.
5️⃣ A culture of compliance strengthens the entire organization.
Training employees in internal control helped change habits and prevent irregularities in the future.
Conclusion
This case demonstrates that effective internal control not only mitigates risks, but also generates value for the company. Through well-designed audits, the use of technology, and a culture of compliance, the organization transformed a weakness into an operational strength.
Each company faces unique challenges, but the principles of this case can be adapted to various industries. The key to success is to combine solid processes, technology, and internal audit to ensure transparency and efficiency in business management.
