Source to pay transactions with GEP SMART

Our new procurement platform

GEP SMART is Ascend Performance Material's new sourcing platform that will streamline and improve procure-to-pay processes for Ascend and its suppliers.

GEP SMART is a free, cloud-native solution powered by our third-party software provider GEP. That will provide transparency, ensuring timeliness of transactions, channel communication and sustainability.

The transition to GEP began in 2022 globally, with a rolling deployment schedule across the different Ascend sites and affiliates. Within this period, we invite our indirect suppliers to join us in this change by creating a supplier account via the GEP SMART Portal or integrating their enterprise resource planning (ERP) systems with GEP SMART.

Eventually, GEP SMART will replace all other legacy systems currently in use at Ascend Performance Materials.

When the ERS function is used, approved service confirmations automatically convert to invoices, eliminating the requirement to go back into the GEP portal to submit invoices against the approved service confirmations.

Please do not submit a copy of invoice via email if submitting on portal as this will cause delays in payment.

If NOT registered on GEP portal, the supplier may submit via PDF in email to
