Uisce Éireann iSupplier Portal

iSupplier is an Oracle EBS module that will allow external suppliers to track activity on their account as well as enter invoices directly onto Uisce Éireann’s system.

Benefits of iSupplier

There are many benefits to this system that will be applicable to you:

  • Invoices automatically processed rather than entering the accounts payable processing queue. You will be entering invoices against approved Purchase Orders. This will speed up the processing and as a result, the payment of invoices.
  • More accurate invoicing against purchase order lines. This supports the receipting process matching the invoicing to ensure payment is made. Real time access to your approved Purchase Orders.
  • Information transparency, from the moment the Purchase Order is available to the final payment
  • Reduced number of queries as a result of only being able to input invoices against approved purchase orders.
  • Cycle time reduction – Less paperwork, faster payments.
  • Ability to provide better customer service while working more efficiently.
  • Easy-to-use interface in a self-service environment.
