Coupa Supplier Portal

The Coupa Supplier Portal (CSP) provides efficient management of Purchase Orders (POs), invoice submissions, and tracking payments.

The implementation of CSP will improve the way suppliers do business with AECOM, simplifying and standardising the way we work together and removing process complexities.

Benefits of CSP include:

  • Real time tracking of POs, invoice status and payments on your CSP account dashboard
  • Create invoices directly from POs with no need to send invoices separately
  • Get paid more efficiently with e-invoicing and digital payments
  • Higher degree of data accuracy from supplier account self-maintenance capabilities
  • No cost to register or transact on CSP
  • Moving to electronic solution limits paper invoices and supports environmental, social, and governance (ESG) commitments and your sustainability credentials.
