Case Study: AON

Aon Reduces Costs by Expanding Automation

Optimizing the procurement process to drive better purchasing management

The Business

Before selecting Corcentric, Aon France handled their entire purchasing process, from purchase requests to invoice matching, manually. With their regional French headquarters in Paris, and eight subsidiaries in different parts of the country, the purchasing function was completely decentralized.

In order to improve the organization’s processes, Stéphane Dubois, General Resources Manager, wanted to centralize the purchasing function. “The purchasing department was created in 2003 to centralize our purchasing activities. The goal was to standardize processes and approval workflows for indirect purchasing,” says Dubois.

Besides this standardization, the average approval time was still long mainly because of the use of paper trail leading to document loss. In addition, there were a lack of compliance and a high percentage of maverick spend due to a lack of budget monitoring.

Aon was looking for a solution that could automate all their operational tasks while monitoring their performance. They also wanted to drive better spend control and better financial security by minimizing discrepancies. “By automating our procurement process, Corcentric drives better purchasing management, from contracts to invoicing, as well as a better price negotiation power. Corcentric has eliminated the issue related to paper trails, improved the quality control of our purchases, but also has been driving better reporting and better forecasting,” says Stéphane Dubois, General Resources Manager, Aon France.

The Experience

Corcentric was selected by Aon for its flexibility and its capacity to automate their source-to-pay process while improving control.

“Due to the evolution of IT systems and the high demand of our executives for cost reduction and financial security, the big trend of purchasing optimization projects has led us to implement a procurement software to manage our indirect costs,” says Stéphane Dubois.

That implementation was rapid, as Aon deployed Corcentric Procurement, Invoice Management, and Financial Management solutions in only a few months. The main objectives of the deployment were to centralize the entire purchasing process, to automate approval workflows, and to improve Aon’s reporting capacity in order to improve their forecasting capacity.

Using Corcentric, Aon has been able to manage all their purchasing within one centralized application. The organization has improved their supplier management as the organization deals with +600 suppliers. Corcentric has also led to better contract management and sourcing practices (RFPs).

By getting rid of paper and moving to electronic invoicing, Aon has been able to speed up the invoice matching process, simplify their dispute management, leading to indirect spend cost reductions.

In addition, by using Corcentric’s reporting capacity for quarter end, Aon has been improving their spend analysis.

Thanks to its flexibility, Corcentric has been able to answer Aon’s specific requirements. Corcentric’s intuitive interface has ensured fast user adoption for 150+ users, minimizing change management costs.
