Katana is excellent if you manufacture your own products. But if you buy finished goods and sell them across eBay and Shopify, you're paying £149/month for bills-of-materials and production runs you'll never use. Salync gives you everything you actually need, from £99/month.
No credit card required · Free plan available
Katana is a great tool — but it's designed for small manufacturers who make physical products. Most UK eBay and Shopify sellers buy finished goods from suppliers and resell them. For those sellers, Katana's manufacturing features are irrelevant noise, and the lack of eBay integration is a dealbreaker.
No eBay integration
Katana has no native eBay connector. If eBay is part of your channel mix, you need a different tool.
Manufacturing overhead
Bills of materials, production orders, and assembly tracking are powerful features — but most resellers pay for them and never open them.
No free plan
Katana requires a credit card for its 14-day trial and has no free tier. Salync is free for up to 50 SKUs with no card needed.
For UK resellers on eBay and Shopify, Salync covers everything you need without the MRP features you don't.

In Katana, go to Products and export your catalogue as CSV. Include SKUs, barcodes, costs, and current stock levels.
Upload the CSV in Salync's import tool. SKUs, descriptions, costs, and barcodes map across automatically.
Link your eBay and Shopify accounts via OAuth. Salync matches your existing listings to the imported catalogue.
Once you confirm stock levels look correct, activate real-time sync. You can run both tools briefly in parallel for peace of mind.
No production orders. No assembly jobs. Just stock that syncs across all your channels.

Bi-directional Shopify sync — stock changes on either side are reflected everywhere within seconds.
Purchase orders

Multi-channel listing
One product catalogue. Push to eBay, Shopify, WooCommerce, and Etsy from a single screen with per-channel overrides.

Connect eBay and Shopify in under 5 minutes. No consultants. No complex onboarding. Real-time sync starts immediately.
Katana starts at around £149/month with no free plan — only a 14-day trial that requires a credit card. For sellers who just need stock sync and channel listing, this is expensive for features they will never use.
No. Katana has no native eBay integration. It is built for Shopify sellers who manufacture products. If you sell on eBay, Katana is not the right tool.
Katana is an MRP (manufacturing resource planning) tool for small manufacturers selling on Shopify. It handles bills of materials and production runs — features most UK resellers do not need.
Salync is built specifically for UK multi-channel sellers — eBay, Shopify, WooCommerce, Etsy, and more. Real-time sync, purchase orders, and listing management without MRP overhead.
Yes. Export your catalogue from Katana as a CSV and import it into Salync. Most sellers are fully migrated in a single afternoon.
