How to Automate Inventory Management with n8n

Monitor stock levels, predict reorder points, generate POs, and alert on supply chain anomalies.

The problem

Operations teams manually check inventory levels and create purchase orders. Stockouts and overstock both cost real money.

The outcome

Reorder happens automatically before stockout. POs generated and sent for approval without manual intervention.

The tool

n8n — Open-source workflow automation with a visual builder.

How it works — step by step

  1. 1

    Real-time inventory levels monitored against reorder thresholds

  2. 2

    Forecasting model predicts depletion based on historical velocity

  3. 3

    Draft PO generated and sent to approver when threshold hit

  4. 4

    On approval, PO transmitted to supplier automatically
