Shuttle Features Inventory

Inventories

Stock levels that stay in sync — without you checking

When a sale happens on Etsy, Shopify updates. When you restock in Shopify, Etsy adjusts. Shuttle bridges the gap between both platforms so you never have to reconcile stock manually again.

Without inventory sync, you're dealing with

Overselling. A sale on Etsy that doesn't update Shopify fast enough. Now two customers think they're getting the last one.

Constant checking. You restock in Shopify, then open Etsy to mirror the change. Multiply that by every product, every day.

Silent drift. Stock numbers quietly diverge between platforms. You don't notice until a customer complains.

01

Automatic stock syncing between Etsy and Shopify

When a sale, restock, or adjustment happens on either platform, Shuttle detects it and updates the other within a few minutes. No schedules, no manual work. Stock stays aligned across both shops automatically.

Bidirectional by default

Sync runs in both directions. A sale on Etsy reduces Shopify stock. A restock in Shopify increases Etsy stock. You choose which direction to enable, or run both.

Platform-aware syncing

Etsy and Shopify handle stock differently. Etsy allows stock at the product level or the option level. Shopify only tracks at the variation level, tied to specific inventory locations. Shuttle understands these differences and bridges them, automatically detecting each variation's primary location and falling back to a default when needed.

Exclude what you don't want synced

Not every product needs syncing. Tag specific products to exclude them from stock sync entirely. Useful for platform-exclusive items or products you manage manually.

Full sync history

Every sync is logged and searchable for 60 days. See exactly what changed, when, and on which platform. No guesswork about what Shuttle did or didn't update.

Bundles that deduct stock from each component

Sell a gift set, and Shuttle adjusts the stock of every item inside it. No spreadsheet math, no forgetting to update the candle count after the bundle sold.

Component-level stock deduction

Define which products make up a bundle. When the bundle sells, Shuttle reduces stock for each individual component across both platforms.

Shopify bundle support

Shopify doesn't allow direct quantity adjustments on bundle products. Shuttle handles this by expanding a bundle into its individual components and adjusting the stock of each one on Shopify. If a component also has a matching Etsy listing, Shuttle syncs the updated stock level to Etsy as well.

Shared SKU syncing

If the same SKU appears on more than one listing, Shuttle keeps all of them at the same stock level. A sale on any one of those listings updates all the others.
