Top 10 Best Practices in Accounts Payable (AP)

Every AP team should focus on the following points to ensure efficiency, control, and strong financial operation. 

1. Standardize the Procure-to-Pay (P2P) Process 

What is P2P? It is the complete process a company follows from identifying the need to purchase something to making the payment to the supplier. It is the core operational cycle of the Accounts Payable (AP) area. 

• Define steps, responsibilities, and timelines. 

• Minimizes errors and speeds up the processing cycle. 

2. Implement Strong Internal Controls 

• Segregation of duties (who creates, who approves, who pays). Prevent one person from having full control of the process. For example: 

• One person creates the vendor. 

• Another approves the invoice. 

• Another executes the payment. 
  This reduces fraud risks and undetected errors. 

• Clear and updated approval matrices. Define who can approve what, based on: 

• Amounts 

• Type of expense 

• Department 
  The matrix must be documented, published, and reviewed periodically to ensure that only authorized individuals approve purchases and payments. 

3. Strict Invoice Validation 

• Review mandatory data, PO, quantities, prices, dates, and discrepancies. 

• Use 3-way match when applicable: 

• Purchase Order 

• Goods Receipt 

• Supplier Invoice 
  If discrepancies exist, the process is paused until resolved. This prevents incorrect or duplicate payments. 

4. Maintain Clean and Updated Master Data 

• Vendors without duplicates and with verified bank accounts. 

• Formal processes for vendor creation and changes. 

5. Prioritize Payments Strategically 

• Take advantage of early payment discounts. 

• Avoid unnecessary advance payments. 

• Maintain a healthy DPO. 

6. Perform Regular Reconciliations and Maintain Discipline During Closing 

• Keep AP aging updated. 

• Reconcile GR/IR, clearing accounts, and disputed invoices. 

7. Clear Documentation and Traceability 

• Keep supporting documents accessible and organized. 

• Facilitates audits and dispute resolution. 

8. Effective Communication with Suppliers 

• Response SLAs. 

• Clear channels for inquiries, disputes, and follow-up. 

9. Efficient Use of the ERP and Automation 

• Workflows, OCR, automated validations, dashboards. 

• Minimizes manual work and reduces errors. 

10. KPIs and Continuous Analysis 

• Invoices processed per analyst. 

• Cycle time. 

• % of invoices with discrepancies. 

• Late vs. on-time payments.
