The ERP Bridge is how Nexus connects to the systems you already run. Every connector is governed by a configuration-driven registry that holds the field mappings, sync frequency, authentication and retry policy, so adding a source is configuration rather than a project. Connections are bi-directional where the system allows: validated records are written back to the ERP, the vendor master is de-duplicated across systems of record, and purchase order amendments are cascaded to every open transaction.
Ten pre-built source channels, each governed by the same connector registry.
AP and finance. REST API, OAuth 2.0, bi-directional, real time.
Procurement. REST API with an API key, bi-directional, scheduled.
Invoice management. Webhook with OAuth 2.0, push events.
SuiteQL REST with OAuth 1.0a, bi-directional.
AS2, ANSI X12, with the 810, 850, 855, 856, 820 and 997 transaction sets.
IMAP/SMTP with attachment extraction; Google Drive, SharePoint, Box and OneDrive by folder watch; inbound REST with HMAC authentication for anything else.
Not a one-way read. Records validated in Nexus go back to the system of record.
Approved invoices published as AP vouchers into Oracle and SAP, with rollback if the write fails.
Records published bi-directionally, so the ERP and Nexus agree on what was approved.
Vendors de-duplicated across every system of record that holds them.
A purchase order amendment applied to every open transaction that hangs off it.
No. Each source connects directly through the connector registry. There is no middleware layer at any phase of the rollout.
No. Nexus uses the interfaces your ERP already exposes. Nothing inside the ERP is modified.
It is rolled back, so the ERP is never left holding a partial record.
810 invoices inbound, 850 purchase orders outbound, 856 advance ship notices and 855 PO acknowledgements inbound, 820 remittance outbound, and 997 functional acknowledgements in both directions.
