Preventing overselling

Overselling is the number one fear for multichannel sellers. Two platforms, two inventory systems, and a window of just minutes for stock to drift out of sync. These articles cover how to keep it accurate.

How to prevent overselling when you sell on Etsy and Shopify
Etsy and Shopify don't talk to each other. When a sale happens on one, the other has no idea. The window for overselling is smaller than most sellers expect — and it happens quickly without automatic sync.

Managing bundle and kit inventory across two shops
Bundles create dependencies between products. A sale of the bundle affects the stock of the components. A sale of a component affects how many bundles you can fulfil. The math gets wrong fast without automation.

Frequently asked questions

How quickly does Shuttle sync inventory between Etsy and Shopify?
On Growth plans and above, inventory syncs in real time — stock updates reach the other platform within minutes of a sale. On Essential plans, stock updates happen on-demand when transfers run.
Does Shuttle handle bundle and kit inventory?
Yes. Shuttle tracks bundle components at the SKU level. When a bundle sells, each component's stock decreases by the correct amount on both platforms. When a component sells individually, bundle availability recalculates automatically.
What happens if my Etsy and Shopify SKUs don't match?
Shuttle's Smart-Matcher can link products by SKU, title, or variation name. Consistent SKUs give the most accurate matches, but mismatched or missing SKUs don't block you from syncing. Shuttle also includes a SKU Audit tool to help you find and fix inconsistencies.
