Shopify ↔ WMS integration for ecommerce warehouses
Orders leave Shopify cleanly; the floor works in the WMS; stock and status come back without nightly CSV theatre.
Sub-15 Second Event Sync
100% Idempotent Processing
Live Short-Pick Supervisor Alerts
Zero Nightly CSV Transfers
The Architectural Engine
Test the operational logic, data paths, and operator experience before code is written.
Transactional Event Architecture
Real-Time Idempotent Webhook & Queue Ingestion
Payload signed via HMAC. Enqueued to Redis buffer with order ID as idempotency key to prevent duplicate processing.
WMS inventory check executes against physical location. Safety stock buffer applied; wave pick ID generated.
Picker scans tote barcode. Barcode scanner validates SKU match. Any discrepancy routes directly to supervisor queue.
Shipping label scanned. Tracking number, carrier code, and fulfillment status pushed back to Shopify with customer SMS.
The operational breakdown.
The Failure Mode
Shopify shows available stock the warehouse does not have. Pickers work from prints or a second system. Delays never make it back to the storefront until a customer emails.
The OpsPatch Solution
Map the real events, allocate, pick, pack, ship, cancel, then build a durable bridge: authenticated APIs or staged files, idempotent updates, and an exception board for shorts and carrier fails.
What This Solves
One inventory story. Ops sees exceptions early. Customer-facing status tracks what actually happened on the floor.

How OpsPatch builds systems.
We do not sell seat licenses or drag out 12-month agency retainers. You hire us to build working software that you own.
Agreed Before Code Starts
We review your data schemas, endpoints, and edge cases. You receive a written scope with fixed delivery milestones and price.
Zero Vendor Lock-In
The complete source repository, Docker configs, and database migrations belong to you. No proprietary runtime or monthly seat fee.
Logging & Operator Runbook
Delivered with automated exception alerts, telemetry, and documentation so your floor operators and developers can run it without us.
Frequently answered questions
Do you replace our WMS?↓
No. We connect the systems you already run, or extend them. Rip-and-replace is a different project class.
What if our WMS only exports files?↓
File drops and scheduled pulls are fine when APIs are weak, as long as ownership, timing, and failure handling are explicit.
Tell us your current stack and where the friction is.
Send your endpoints, spreadsheets, or what is currently breaking on the floor. We review your dependencies and respond with an exact architecture approach and likely starting scope.

Commerce and warehouse systems talk to Dynamics 365 on purpose, with audit trails, not copy-paste between finance and ops.

Pack stations stop guessing box size. Fill rate climbs; dimensional weight and void fill drop.

Hot SKUs land where feet already go. Pick paths shorten. Slotting follows demand and inventory days, not tribal memory.
