About this Gig
Shopify stock showing wrong numbers across channels? Orders slipping through because inventory didn't update? I fix it.
Hi, I'm Liam. I build reliable Shopify inventory sync and multichannel stock sync systems that actually work. No generic app installs. I find the root cause, fix the sync errors, and set up automation so your stock stays accurate across every channel in real time.
What I handle:
- Shopify inventory sync and stock sync fixes
- Multichannel sync: Amazon, eBay, TikTok Shop, Etsy, Walmart
- Order fulfillment automation and order routing
- Shopify API integration and webhook setup
- n8n, Make, Zapier and Shopify Flow automation
- QuickBooks, Zoho, Odoo ERP sync
- Shopify POS and multi-location inventory sync
- SKU mapping, variant fixes, CSV and supplier feed import
- Stocky migration to Prediko or Sumtracker
- Sync error debugging, logging, and alerts
Every setup is tested with sample orders before handover. You get documentation, sync logs, and post-delivery support.
Whether you need a quick sync fix or a full multichannel automation build, message me your store link, channels, and what's breaking. I'll confirm scope and timeline before you order.

FAQ
What is Shopify inventory sync and why is my stock wrong across channels?
Shopify inventory sync keeps stock accurate between your store and channels like Amazon, eBay, TikTok Shop. When it breaks you get overselling and mismatches. I find the root cause — polling delay, SKU mismatch, or API error, and fix it.
Can you fix multichannel inventory sync between Shopify and Amazon?
Yes. I fix and set up Shopify to Amazon inventory sync using Marketplace Connect, CedCommerce, LitCommerce, or direct Shopify API and Amazon SP-API. I configure real-time stock sync so sales on one channel update the other instantly.
What tools do you use for Shopify multichannel stock sync?
Depends on your setup. I use CedCommerce, LitCommerce, Trunk, Sumtracker, Sellbrite, BaseLinker for app sync. For custom builds I use Shopify API, n8n, Make, Zapier, Shopify Flow. I recommend the right tool after reviewing your store.
Can you set up order fulfillment automation for my Shopify store?
Yes. I automate order routing to your fulfillment center, 3PL, or supplier. Includes tracking sync, status updates, and multi-location inventory deduction. Works with Amazon MCF, ShipStation, and custom 3PL APIs.
Do you fix Shopify to eBay product sync and inventory issues?
Yes. I fix variant mismatches, inventory not updating, duplicate listings, and webhook failures between Shopify and eBay. If Marketplace Connect broke your sync I repair it or set up a direct API integration that stays connected.
Can you help with Stocky migration before it shuts down?
Yes. Stocky shuts down August 31 2026. I migrate your purchase orders, supplier data, and stock history to Prediko, Sumtracker, or your preferred replacement. Everything is backed up first so nothing gets lost.
Do you integrate Shopify with QuickBooks, Zoho, or Odoo?
Yes. I set up sync so orders, inventory, and product data flow between Shopify and QuickBooks Online, Zoho Inventory, Zoho CRM, or Odoo automatically. Keeps your books accurate without manual data entry.
Can you set up Shopify POS inventory sync with my online store?
Yes. I configure Shopify POS so in-store and online inventory stay synced in real time across multiple locations. Includes barcode setup, staff permissions, multi-location stock management, and hardware config.
How long does it take to fix a Shopify inventory sync issue?
Single-channel sync fix: 1-3 days. Multichannel setup for 2-3 channels: about 5 days. Full automation build with order fulfillment, ERP sync, and custom workflows: 7-10 days. I confirm your timeline before you order.
What do I need to provide before you start?
Your Shopify store link, sales channels you use, what is broken or what you want set up, and any error screenshots. I review your setup, confirm scope and plan before you order. Collaborator access to Shopify admin is needed once we start.
