When a product is listed on eBay and Shopify at the same time, the risky moment is obvious: one item sells, the other channel still thinks it is available, and a second buyer places an order before your stock is corrected.
Start with a shared product view
Before automating anything, identify which marketplace listings represent the same physical stock. Review titles, SKUs, images, variants, and account source. If two listings are actually one product, group them intentionally.
Watch orders and quantities together
Order management and inventory belong next to each other. A sale changes stock. A cancellation, return, manual adjustment, bundle component, or purchase order can change the available quantity too. The daily workflow should make those changes visible.
Use profit as a reality check
A product can be in stock and still be unhealthy. Keep COGS, shipping assumptions, marketplace fees, and selling price close to your inventory workflow so fast-selling items are not quietly losing margin.
