Multi-Storefront Real-Time Inventory Sync & Supply Chain Pipeline
Replaced a fragmented email-and-spreadsheet order flow with a high-throughput data reconciliation engine syncing warehouse stock across multiple channels in sub-2 seconds.
ILLUSTRATIVE REFERENCE ARCHITECTURE • SAMPLE SCENARIO & DESIGN TARGETS • NOT A NAMED CLIENT OR VERIFIED RESULT
Operational Bottleneck & Friction
In this scenario, a wholesaler supplies many regional distributors. Disconnected inventory sheets cause overselling, and staff spend hours every week calculating tier pricing and drafting invoices by hand.
How it Operated Before Automation
Distributor emailed PO PDF -> Staff checked 3 different warehouse spreadsheets -> Manually calculated volume tier discounts -> Created draft invoice in accounting software -> Emailed back for approval.
The Automated Digital System
Portal 1-Click Order
Distributor submits order via secure portal.
Atomic PostgreSQL Lock
Acquires row-level atomic lock on inventory SKUs.
Automated Tier Math
Applies contractual volume pricing instantly.
Stripe Invoice Dispatch
Generates and delivers Stripe invoice PDF.
Automated Shipping Alerts
Syncs warehouse dispatch tracking webhooks.
Design Targets & Sample-Scenario Impact
Stock levels
One stock count shared by every storefront.
Volume pricing
Contract pricing applied automatically.
Dispatch updates
Customers receive tracking without asking.
Engineered Workflow & Integration Flow
B2B Portal Order Webhook / Warehouse Stock Adjustment
Calculate volume tier discount matrix, compute shipping freight, aggregate SKU line items
IF stock >= order_quantity THEN acquire atomic lock & proceed; ELSE trigger backorder workflow
Atomic PostgreSQL Update + Stripe Invoice PDF + Dispatch Tracking Webhook to Distributor
Logistics Reference Build (Illustrative Scenario) — Live Workflow Canvas
Explore how the data transforms at each step from trigger to multi-channel execution.
Non-visual workflow sequence for Multi-Storefront Real-Time Inventory Sync Pipeline:
- Step 1: Order Webhook Event (Event Trigger). Fires instantly whenever an order is completed on any storefront.. Integration: Shopify Webhook API.
- Step 2: PostgreSQL Lock & Delta Check (Atomic Database Operation). Acquires row-level atomic lock on SKUs to prevent concurrent race conditions.. Integration: Supabase / PostgreSQL.
- Step 3: Inventory Deduction Matrix (Data Calculation). Calculates new unified stock balances across regional fulfillment centers.. Integration: n8n JavaScript Transform.
- Step 4: Safety Threshold Check (Business Rules). Evaluates if remaining stock falls below reorder threshold.. Integration: Threshold Engine.
- Step 5: Multi-Channel Stock Push (Parallel API Dispatch). Dispatches parallel stock updates to Shopify, Amazon, and ERP endpoints.. Integration: Shopify REST + Amazon SP-API.
- Step 6: Audit Log & Analytics Sync (Observability). Writes immutable transaction log and increments real-time dashboard counters.. Integration: ClickHouse / Dashboard API.
