In the digital era, applying automation to prevent fraud is a strategic move that helps businesses not only optimize performance but also transform the role of accountants into strategic financial professionals, especially in internal control. Automated invoice processing not only speeds up the process but also establishes a solid defense barrier, thoroughly preventing the risks of fraud and duplicate payments, which are the largest potential risks in manual procedures.

Operational Reality: Control Gaps in Manual Processes
Financial and accounting operations in many businesses today, particularly the Accounts Payable process, still heavily rely on manual tasks. The very nature of human intervention, coupled with the complexity and repetitive nature of the procedures, creates serious vulnerabilities.
Risks of Manual Errors and Internal Fraud
A high demand for accuracy is paramount to prevent fraud risks or manual human errors that lead to financial loss. However, manual processes always carry inherent risks:
- Human Replication Errors: Manually entering data from paper invoices or emails into the ERP/accounting system easily leads to errors in quantity, unit price, or vendor code, causing significant discrepancies in financial reports.
- Opportunistic Fraud: When an individual or a small group can execute multiple steps in the process (e.g., invoice entry, approval, and payment order creation), they can easily generate fraudulent invoices, modify payment information, or intentionally lose invoices to conceal transactions.
- Duplicate Payments: Because invoices are processed through multiple channels (email, paper, system) without an immediate reconciliation mechanism, businesses often end up paying the same invoice to the same vendor multiple times.
Real-World Statistics: According to a global report by the Association of Certified Fraud Examiners (ACFE), fraud related to dummy invoices and expense abuse is one of the most common forms of corporate fraud. As a result, companies must strictly tighten internal controls, but still have to accept high operating costs and slow processing times.
Control Pressure Increases Operating Costs
To mitigate the aforementioned risks, businesses often have to tighten internal controls by adding multiple approval steps, cross-checks, and segregation of duties. This inadvertently creates bottlenecks in the process, delaying payments, causing the company to miss out on early payment discounts, and reducing employee experience.
Applying Automated Invoice Processing for Internal Control
Automating invoice processing by combining Robotic Process Automation (RPA) and Intelligent Document Processing (IDP) technologies not only solves performance issues but also establishes a robust, objective internal control system, eliminating vulnerabilities caused by human factors.
Use Cases for Enhanced Internal Control
| Internal Control Mechanism | Automated Invoice Processing Solution | Operational Value (Anti-Fraud) |
| Preventing Duplicate Payments | Real-time Data Matching: The Bot automatically matches the new invoice against all invoices already entered and paid in the ERP system based on multiple criteria (Invoice Number, Tax Code, Total Amount). | Eliminates 100% of duplicate payment risk. Saves potentially billions of dong in annual losses. |
| Verifying Validity | Tax Authority API Integration: The Bot automatically checks the legality of the e-invoice (whether it has been canceled, adjusted, or if it is a phantom invoice) immediately upon receipt. | Prevents the entry and payment of fake/illegal invoices, minimizing administrative penalty risks. |
| Segregation of Duties | Digital Approval Workflow: Automatically enforces a multi-level, hard-coded approval flow, ensuring the entry person cannot be the approver or the payment order creator. | Eliminates opportunistic fraud risk where one person controls multiple steps, enhancing transparency. |
| Expense Threshold Control | Smart Rule Setup: The Bot automatically compares the invoice value against the Purchase Order or budget limit. If the threshold is exceeded, the invoice is automatically routed to a higher approval level or flagged as a warning. | Reduces losses from uncontrolled over-budget expenses. |
Tangible Value of Automation
Applying automation to the Accounts Payable process is not just a technology investment; it is a financial protection shield:
- Accuracy and Compliance: Data entry accuracy reaches 95% – 99%, minimizing manual errors and ensuring compliance with accounting regulations.
- Processing Time: Shortens invoice processing time from minutes to seconds, freeing up the accounting team for more in-depth control and strategic tasks.
- Cost Savings: Beyond saving labor costs, automation’s ability to prevent fraud and duplication can save the business a significant amount of loss, often many times greater than the initial investment cost.
Global Success Story: Strengthening Internal Control
Many large corporations worldwide have used automation to strengthen internal control. For example, a leading technology corporation like Tesla implemented an Automated Invoice Matching system integrated with AI to monitor and match invoices against purchasing data in real-time.
The Result: This system not only optimized financial efficiency by 30% but also reduced operating costs by 25% by eliminating manual errors, particularly the risk of duplicate payments and uncontrolled anomalies. This demonstrates that automation is currently the most effective financial defense tool.
Lessons Learned for Successful Automated Invoice Processing Application Internal Control
To successfully transform the financial and accounting process and turn automated invoice processing automation into a proactive internal control tool, businesses should note the following key lessons:
Optimizing the Process Before Automated invoice processing for Internal control
- Standardize Source Data: Ensure data from related systems (Purchase Orders, Goods Receipts) is clean and consistent. “Automating an inefficient process only amplifies the inefficiency.”
- Clearly Define Control Points: Before programming the Bot, businesses need to identify specific risks (duplication, price discrepancies, lack of approval) and establish automated control rules at these points.
Enhancing Objectivity and Segregation of Duties
- Separate Technology and Human Roles: Use Bots to perform data recording and matching tasks (creating the control record), while humans only focus on exception handling and final approval. This reinforces the Segregation of Duties principle.
- Establish an Audit Trail: The automation system must record a complete activity log: when the invoice was entered, which Bot processed it, who approved it, and the approval time. This creates complete and transparent control evidence.
- Combining Intelligent Automation: Upgrade from basic automation to Intelligent Automation. Use Artificial Intelligence (AI) to analyze anomalous transactions (e.g., invoices from new, unlisted vendors, invoices with a sudden spike in value) and automatically generate alerts for the Chief Accountant. This is a proactive control mechanism that goes beyond the capabilities of conventional hard rules.
In summary, automated invoice processing for internal control is an essential investment for the Finance and Accounting department to transform into a strategic accounting unit, not only by increasing speed but also by establishing an unmanipulable internal control system, thus protecting the assets and compliance of the business.
