FAQ

Common questions about Shopify & Amazon sync

Does it work with FBA inventory?
Yes. Commerce Kitty syncs FBA (Fulfilled by Amazon) inventory to your Shopify store. When Amazon receives or ships FBA stock, your Shopify inventory updates automatically.
How does ASIN matching work?
Commerce Kitty automatically matches your Shopify products to Amazon ASINs using SKU, UPC, and title matching. You review the suggested matches and confirm them. For products that don't auto-match, you can link them manually in one click.
What if I sell different quantities on each platform?
You can set channel-specific stock buffers. For example, keep 5 units reserved for Amazon and make the rest available on Shopify. Commerce Kitty respects your allocation rules while keeping totals accurate.
Will this affect my Amazon Buy Box eligibility?
It helps it. Fewer cancellations and stockouts improve your seller metrics, which Amazon factors into Buy Box decisions. Accurate inventory means better account health.
Can I add more channels later?
Absolutely. Start with Shopify and Amazon, then add eBay, Etsy, WooCommerce, or BigCommerce whenever you're ready. Your sync setup carries over.
