Quick Facts
Industry: Manufacturing & Distribution
Vendors: 350+ active suppliers
Timeline: 6 weeks
POs/Month: 1,200+
Stack: n8n, SAP, NetSuite, Slack
The Challenge
A mid-market manufacturer managing 350+ suppliers relied on spreadsheets and email threads to track vendor onboarding, compare quotes, and route purchase orders for approval. PO cycle times averaged 8 days and procurement errors regularly caused shipment delays.
Finance spent 20+ hours each week reconciling POs against invoices and goods receipts in the ERP, while missing duplicate payments and contract-rate violations slipped through undetected.
Pain Points
❌ 8-day average PO cycle time
❌ 20+ hours/week on manual reconciliation
❌ Duplicate payments going undetected
❌ No centralised vendor compliance tracking
❌ Quote comparisons done in spreadsheets
Our Solution
🤝
Vendor Onboarding Portal
Self-service portal where new vendors submit company details, tax IDs, and certifications. n8n validates data, runs compliance checks, and provisions vendor records in the ERP automatically.
📊
Smart Quote Comparison
RFQ workflows collect quotes from approved vendors, normalise pricing into a comparison matrix, score suppliers on cost, lead time, and quality, and route the recommendation for approval.
📝
Automated PO Approval Chains
Purchase requests route to the right approvers based on cost thresholds, department budget, and category. Slack notifications, escalation timers, and mobile approvals eliminate bottlenecks.

Bidirectional sync between procurement platform and SAP/NetSuite. Automated three-way matching (PO → goods receipt → invoice) flags discrepancies before payment is released.
