Most sellers lose weeks and thousands to messy marketplace setups, oversold stock and rejected listings. I help you skip that.
I connect Shopify to Amazon, Walmart, eBay, Etsy and TikTok Shop with real-time inventory sync, clean listings and approval-ready stores, so you sell everywhere without spreadsheet chaos.
Recent: a Shopify store live on Amazon, Walmart and eBay with synced stock. A Walmart application fixed and resubmitted. Hundreds of products mapped, zero overselling.

FAQ
What does the Shopify catalog API do for my store?
It lets Shopify exchange product data automatically with your supplier, ERP or marketplace. Titles, images, prices, variants and stock stay accurate without manual uploads or CSV edits.
Can you connect my supplier’s feed or API to Shopify?
Yes. I work with REST API, GraphQL, XML, CSV, FTP and Google Sheets feeds. Send me the feed link or API docs and I’ll confirm for free whether it can be automated.
Will product sync and inventory sync run in real time?
It can, using webhooks for instant updates, or on a schedule (every 15 minutes, hourly or daily) if your source doesn’t support real-time. I’ll recommend the best option for your setup.
How do you prevent duplicate products and overselling?
I map every product and variant to your supplier SKU, so existing items are updated, never recreated. Stock rules and buffers stop one channel from selling what another has already sold.
Can you sync Shopify with Amazon, eBay, Etsy or TikTok Shop?
Yes. I handle Amazon to Shopify, eBay, Etsy and TikTok Shop product sync, inventory sync and order automation. Tell me which channels you use and I’ll scope the work.
Do I need a paid app, or is it custom-built?
It’s a custom Shopify API integration, so you avoid extra monthly app fees. If a third-party tool would genuinely do the job better, I’ll tell you before you pay.
What happens if something breaks after delivery?
Every integration includes error logs and alerts, plus a tested handover with clear setup notes. Free fixes for issues in the agreed work are covered during support, and I’m available for ongoing maintenance.
Is my store data and API access safe?
Yes. I use a Shopify custom app with only the scopes needed, and I never ask for your password. You can revoke access at any time, and I keep credentials out of the code.
Can you fix an existing broken Shopify integration?
Yes. I debug API errors, webhook failures, missing or duplicate products and mismatched inventory. Share the error details or the app involved and I’ll review it before you order.
How do I choose the right package?
Basic suits a small one-source import of up to 100 products. Standard covers up to 1,000 products with variants, inventory and error logs. Premium is for two-way multi-source sync with webhooks and GraphQL.
