GatewaySyncHow it works
← All integrations

Coupa invoice submission, without leaving GatewaySync

Connect your organization's Coupa instance once, and every open purchase order syncs into GatewaySync's consolidated table — ready to invoice against alongside every other portal you work with.

1

Link Coupa

Sync open purchase orders and submit invoices directly to Coupa.
2

See every open PO

Open purchase orders from every connected portal appear in one table, tagged by source.
3

Submit in one place

Fill out the required fields and submit — GatewaySync routes it to the right portal and tracks confirmation status.

Connecting Coupa to GatewaySync

Coupa is a per-tenant instance (yourcompany.coupahost.com), so there's no shared GatewaySync client — you register your own OAuth2/OpenID Connect client under Coupa's Setup → Integrations menu and enter the resulting credentials on the Portal Links page.

Every organization registers its own OAuth app — GatewaySync never has a shared, platform-wide client for this portal.
