Automated Invoice Payment Process thru SAP Ariba

by Unionbank Human Resources Group

UnionBank was heavily reliant on manual, paper-based invoice processing, which  caused significant delays, frequent errors, and compliance risks. As invoice volumes  grew, the process became increasingly unsustainable, straining resources and limiting  scalability. Vendors also experienced poor visibility, leading to frequent inquiries and  dissatisfaction. This inefficiency highlighted the urgent need for digital transformation in  invoice processing operations.  

The General Services Group was assigned to lead the implementation of a digital  solution that would automate and streamline the invoice payment process. The goal  was to eliminate paper-based workflows, improve turnaround times, and enhance  vendor experience. The solution also needed to be scalable, secure, and compliant with  financial standards. Success would be measured by operational efficiency, cost savings,  and stakeholder satisfaction.  

To address the challenge, the team deployed a cloud-based SAP Ariba system that  automated invoice submission, PO reconciliation, and approval workflows in SAP. They  digitized the entire process, enabling secure electronic transactions and eliminating  paper handling. Cross-functional collaboration with Accounting, Procurement, and IT  ensured smooth adoption and helped identify and resolve bottlenecks. The team  championed full automation with a focus on sustainability, scalability, and compliance. In  just 5 months, the team experienced an unprecedented ease in the invoice processing  activities and resulted in: 

  •  Reduced invoice processing time from 15 days to 2 days 
  • Achieved a 4-FTE reduction 
  • Projected Php10M cost savings over five years
  • Enabled 100% paperless transactions, improving sustainability and document security
  • Improved vendor transparency and reduced inquiries

The project directly supports the organization’s digital transformation goals and aligns  with broader financial technology initiatives. The initiative is a success story of process transformation—from manual inefficiency to automated excellence—highlighting  teamwork, innovation, and bold decision-making. Ultimately, it positively impacted  internal teams and external vendors, enhancing operational efficiency and vendor  satisfaction while contributing to the advancement of the businesses we partner with  and Filipinos who rely on them.
