Vendor portal automation

Vendor onboarding, invoicing and document handling, with invoices read by OCR whether they arrive as an image, PDF or Word file.

Built for: Vendor operations
Type: Automation

Part of an n8n workflow: a contact lookup with timed retries and a banned vendor check — Part of the vendor portal workflow in n8n: the identity lookup and its retry chain.

The main system

Vendor interactions, invoicing and document processing run through one workflow, with duplicate detection, identity lookups and a retry chain for the steps that depend on outside services.

Reading invoices

A second workflow detects the file type and routes it: images are analyzed directly, PDFs and Word documents go through OCR, and all three end in the same structured submission.
