works\nThis workflow automates inventory monitoring, predictive reordering, and supplier communication using Shopify + Google Sheets.\n\nIt runs hourly to pull live inventory levels, product details, and recent order history from Shopify. In parallel, it reads your Inventory Master, Supplier list, and Purchase Order Log from Google Sheets, then merges all sources into a single SKU-level dataset.\n\nFor each SKU, it calculates sales velocity (7/30-day) and derives a dynamic reorder point based on demand, lead time, and safety stock settings. If current stock drops below the reorder point, it evaluates stockout risk and sends a Slack alert for critical items. Where possible, it checks multi-warehouse redistribution logic to prevent stockouts before ordering.\n\nWhen replenishment is needed, it enriches each SKU with supplier data, verifies availability, calculates optimal order quantity/value, and applies business rules such as MOQ checks, budget limits, and large-order approval thresholds. Items can also be prioritized by profitability to maximize ROI under budget constraints.\n\nThe workflow then structures Purchase Order line items and automatically sends the PO via email and/or a supplier API. After waiting for confirmation, it updates the PO log. It also detects slow-moving products, proposes actions (discounts/bundles), syncs analytics to dashboards/accounting, and sends a daily Slack summary of POs, alerts, and slow-mover suggestions.\n\n## Setup steps\n1. Connect Shopify and set store URL + API credentials in **Workflow Configuration**.\n2. Connect Google Sheets and map the Inventory Master, Suppliers, and PO Log sheets.\n3. Connect Slack and select channels for critical alerts and daily summaries.\n4. Configure lead times, safety stock days, budget/MOQ rules, and approval thresholds.\n5. Run a test with a few SKUs, verify PO creation/logging, then enable the hourly trigger." }, "typeVersion": 1 }, { "id": "1b6471d0-9a5b-4c3d-98af-2cc25dec465f", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ -3152, 336 ], "parameters": { "color": 7, "width": 512, "height": 288, "content": "## Trigger & Configuration\nRuns hourly and loads all business parameters (lead time, safety stock, budget/MOQ rules, thresholds).
