Your stock, connected.
Choose products, check the quantities and turn on synchronization when you are ready.
Checking your account…
1. Connect your stores
Bring your own authorized marketplace API credentials. Your store administrator handles technical setup and any required platform approval. One-click store authorization is not available. You can try the free comparison demo without credentials or a subscription.
Already connected? Use your saved connections to choose products without entering credentials again.
Technical connection setup
Follow the connection guide and store acceptance checks. A successful read does not prove inventory write permission.
This step is for someone who already has authorized marketplace API access. Never share your store password. Credentials are cleared from these fields after submission, and saved encrypted only after you review your mappings.

Amazon merchant-fulfilled inventory
FBA and supply-source inventory are not supported.
eBay published Inventory API offers
Legacy listings must first be migrated through eBay.
2. Match your products
Enter the SKU printed in your product catalog. We find the product IDs for you. Only exact SKU matches are offered; you choose the location and destination.
Shares for the same Shopify item and location must total no more than 100%. Keep some stock unallocated if you also sell elsewhere. This is a publishing limit, not a stock reservation.
Selected matches
Saving replaces the full set of existing mappings and pauses synchronization. Add every mapping you want to keep.
3. Check before switching on
Reading stock is free for your first 10 comparisons. It does not change your stores. Applying a correction requires an active subscription.
4. Turn on synchronization
Faster event-triggered checks
Five-minute reconciliation works without a webhook. For event-triggered processing, your technical setup contact must register the Shopify inventory_levels/update webhook shown after saving. The one-second worker interval is not a promise of marketplace delivery speed.
Subscription and access
$29/month plus applicable tax for up to 100 mappings. Subscribe only after all your connections and mappings verify successfully. Cancel renewal in Manage subscription.
Removing connections stops synchronization. It does not cancel billing.
