Accounts Payable Workflow Automation

Business Context 

The client operated on a legacy finance system that did not have a built-in Accounts Payable (AP) workflow. As a result, the processing of purchase invoices, vendor invoices, and supplier invoices was largely manual, fragmented across emails, folders, and spreadsheets. 

This created challenges around: 

• Approval visibility 

• Duplicate invoices 

• Audit traceability 

• Invoice turnaround time 

• Lack of real-time status tracking 

LeverageAxiom was engaged to design and implement a complete Accounts Payable workflow solution using Microsoft SharePoint, Power Automate, and later Power Apps. 

Key Challenges 

• No structured workflow for vendor invoice approvals 

• Manual data validation and verification 

• High risk of duplicate payments 

• No discrepancy checks between purchase invoice and accounting entries 

• Physical stamping required for compliance but not digitally traceable 

• No centralized dashboard for invoice status 

• Difficult to identify who approved an invoice and when 

Solution Overview 

LeverageAxiom built an end-to-end Accounts Payable automation solution that covers the full lifecycle of: 

Invoice Upload → Validation → Verification → Multi-level Approval → Duplicate Checks → Accounting Reconciliation → Audit Traceability 

The solution was first implemented using SharePoint and Power Automate, and later upgraded into a Power Apps-based system for enhanced user experience and governance. 

End-to-End Accounts Payable Automation Flow 

1. Vendor Invoice Upload 

• Vendor invoices and supplier invoices uploaded to SharePoint 

• Supports scanned invoices and digital PDFs 

• Acts as a centralized invoice intake repository 

2. Data Validation & Verification 

Automated checks include: 

• Mandatory field validation 

• Vendor master verification 

• Invoice number and date checks 

• Purchase invoice completeness validation 

3. Duplicate & Discrepancy Checks 

• Duplicate invoice detection based on: 

• Vendor 

• Invoice number 

• Amount 

• Data entry discrepancy checks between: 

• Purchase invoice 

• Accounting records 

4. Multi-Level Approval Workflow 

Configurable approval flow based on: 

• Invoice value 

• Cost center 

• Department 

• Approval hierarchy 

Supports: 

• Finance review 

• Business owner approval 

• Final Accounts Payable authorization 

5. OCR-Based Stamping & Indexing 

• Physical invoices were scanned and stamped 

• Using OCR, the stamping details were: 

• Extracted automatically 

• Indexed and tagged to the correct invoice records 

• Enables digital traceability of physical compliance steps 

6. Invoice Status Dashboard 

• Real-time dashboard on SharePoint showing: 

• Pending approvals 

• Approved invoices 

• Rejected invoices 

• Paid invoices 

• Provides transparency across finance and business teams 

7. Power Apps Upgrade with Audit Timestamping 

The workflow was further enhanced using Power Apps, adding: 

• Automated timestamp affixing on invoice copies 

• Displays: 

• Who approved the invoice 

• Date of approval 

• Date of payment 

• Stored directly on the invoice file in OneDrive 

Anyone opening the invoice can instantly see: Who approved it, when it was approved, and when it was paid.
