01/Capabilities
Everything you need to manage your stock
No more copy-pasting between spreadsheets and marketplaces. Salync connects every part of your operation in one place.
Central product catalogue
One place for every SKU, barcode, cost, price, and image. Import from eBay or Shopify in minutes and keep your catalogue clean across all channels.
Multi-channel publishing
Push listings to eBay, Shopify, Etsy, OnBuy, Amazon, WooCommerce, and 6 more. Lock fields per channel and catch sync errors before they cost you sales.
Real-time stock tracking
Track stock across multiple locations. Scan barcodes for instant stocktakes, set reorder points, and get low-stock alerts before you run out.
Purchase orders
Raise POs, send to suppliers, and receive stock in a few clicks. Salync suggests reorders automatically when stock hits your threshold.
Shared catalogue links
Share a read-only view of your products with buyers or suppliers — no account needed. Control exactly what they can see.
Reports & exports
Inventory valuation, ABC analysis, dead stock, sales velocity, and supplier performance — all exportable as CSV whenever you need them.
Barcode scanner & labels
Scan with your phone camera or a USB scanner to receive stock, pick orders, or run a stocktake. Print EAN-13, UPC-A, or QR labels in any size.
Team management
Owner, admin, editor, viewer — granular roles so every team member has exactly the access they need. Every action is audit-logged.

Manage from one place.
List on eBay, Shopify, Amazon and more — all without duplicating effort. Lock specific fields per channel so your channel-specific titles and prices stay exactly as you set them, even when you bulk-update your catalogue.

05/Questions
Frequently asked questions
What is multi-channel inventory management software?
Multi-channel inventory management software keeps your stock levels synchronised across all the marketplaces and stores you sell on. When an item sells on one channel, stock updates automatically everywhere else — preventing overselling.
How do I stop overselling on eBay and Shopify?
Overselling happens when your inventory tool updates stock in batches rather than in real time. The fix is software that syncs stock the moment a sale happens on any channel — so you never accidentally sell stock you don't have.
Is there a cheaper alternative to Linnworks for UK sellers?
Yes. Salync covers the same core functionality as Linnworks — real-time stock sync, purchase orders, multi-channel listing management — at a fraction of the cost. Salync starts at £99/month versus Linnworks at ~£500/month, with a free plan for up to 50 SKUs.
What inventory management software is best for eBay sellers UK?
For UK eBay sellers managing up to 10,000 SKUs, Salync is purpose-built for eBay and Shopify with real-time stock sync, purchase orders, and transparent pricing.
Can I manage eBay and Shopify inventory for free?
Yes. Salync offers a free plan for up to 50 SKUs with no credit card required — real-time stock sync between eBay and Shopify, product catalogue management, and low-stock alerts at no cost.
