Find answers to frequently asked questions about Xylem's transition to Coupa Source to Pay.
About the transition
Coupa Source-to-Pay is Xylem’s digital platform that simplifies and streamlines our procurement process—from sourcing to purchase orders to invoicing and payment.
We’re committed to strengthening our supplier partnerships and making it easier to do business with us. Coupa helps create an efficient, transparent, and collaborative process for both Xylem and our suppliers.
Coupa is being rolled out across Xylem globally between 2025 and 2028. Please see Xylem’s Coupa roll-out plan for more information.
All suppliers will be required to transact digitally through Coupa via either;
- CSP: Coupa’s supplier portal where purchase orders can be retrieved, confirmed and easily ‘flipped’ to create shipping notifications, invoices and much more.
- cXML: Real-time, electronic communication of purchase orders, confirmations, shipping notifications and invoices between your ERP and Coupa.
Setting up a cXML connection requires technical resources to configure, test and deploy – so is most suited to high transacting suppliers (see establishing an electronic connection with Xylem). For everyone else, we recommend transacting via the Coupa Supplier Portal (CSP).
CSP: Access and registration
No. The CSP is completely free to use.
There are multiple ways to access the CSP, from receiving an invitation to responding to a SIM request. For more information, please see section 2, 'Ways to join’ of the csp-reference-guide-en.pdf.
You should attend a CSP training session prior to onboarding. Please see further support and training webinars for more information.
Yes. Your designated administrator will manage your company’s profile and can invite additional colleagues to join after onboarding. There’s no limit to the number of users.
CSP: Transacting
You’ll use the CSP to:
- Receive and manage purchase orders
- Submit invoices electronically
- Track order and payment status in real time
- Action sourcing events
- Update your company profile, including remittance and tax info
Yes, you can still receive POs via email. However, using the Coupa Supplier Portal is strongly recommended for the best experience. It allows you to flip POs into invoices with just a few clicks, track status updates, and communicate directly with Xylem.
Unless subject to country-specific e-invoicing regulations, you’ll be able submit invoices through the Coupa Supplier Portal. This helps reduce errors and ensures quicker processing and payment in line with agreed terms.
Existing transactions will continue through current processes until regional go-lives (see Xylem’s Coupa roll-out plan). After this date, any open Xylem Inc. purchase orders will be migrated to Coupa for invoicing purposes. Further details will follow during the regional CSP training webinars.
