To reduce the number of invoices processed without a purchase order to properly control and manage organizational spending centrally through the supply chain department

To be determined after establishing a baseline

Purchasing activity not controlled by the supply chain department is often purchased inefficiently, carrying a higher cost and degree of risk to the organization. This excludes low dollar value purchases procured through established alternate methods. Potential issues and problems that may arise from departments managing their own spending without sufficient supply chain expertise include:
Expanding the scope of goods and services issued centrally by the supply chain department and covered by a PO will provide greater opportunities for savings and process efficiencies throughout the organization.
Financial Stewardship
Greater control by the supply chain department over the purchasing of goods and services will
increase purchasing power and standardization.
Process Efficiency
Accounts payable staff will spend less time obtaining approvals and verifying invoice information from individual departments for invoices that do not have a purchase order. This is a far more timeconsuming activity than simply conducting a three-way match with the PO and receiving slip.
Similar efficiencies can be expected in the receiving department, since delivery information on a non- PO packing slip can sometimes be inaccurate or missing departmental information typically found on the receiving document for an item purchased with a PO.
Risk Management
The risk to the hospital will be reduced by centralizing and increasing control of spending under trained supply chain professionals. The supply chain department should have processes in place to manage and track device licences, recalls and MSDS, which all directly affect patient and employee safety.
Collaborative Planning
The supply chain department must work collaboratively with their customers to understand their
requirements and transition more goods and services under the supply chain department’s control,
thus reducing non-PO spending.
Strategic Sourcing
By rationalizing the supplier base through purchasing volumes and spend analysis, organizations can focus on selecting strategic suppliers and maximizing relationships. For this to be effective, purchases must be made by issuing purchase orders and be controlled centrally through the supply chain department.
Tight Supply Chain/Accounts Payable Organizational Relationship
Working collaboratively, the supply chain and accounts payable departments can implement processes to reduce the number of invoices received without a PO. Accounts payable can identify departments that are not compliant based on the non-PO invoices received, and the supply chain department can work with these areas to assume responsibility for purchases.
“End to End” eSupply Chain
Automation of procurement processes increases the ease of use for customers, which will support compliance with the standard PO process and reduce labour costs associated with purchasing, receiving, and accounts payable.
Establishment: No members of the Working Group are currently tracking this metric in their organization. Consequently, setting an appropriate target is not possible at this time. The Working Group recommends that the metric be reviewed after six to twelve months once a baseline has been established to determine an appropriate target.

CHALLENGING – Data are available but require analysis and custom reporting
Electronic
Accounts Payable Module:
Most financial reporting systems should be able to provide monthly reports on the Number of invoices with purchase orders and Total number of invoices received. Custom reporting could be required.
Manual
If electronic reporting is unavailable, the organization could consider conducting manual counts, selecting a representative sample, or using a logging method throughout the month. Organizations should select the option that balances the cost of collecting the data and the associated accuracy with the benefit of reporting the metric.
