How to perform inventory linking in SiteGiant

Introduction


Inventory linking connects your marketplace listings to the correct inventory item (iSKU) in SiteGiant so stock can be updated correctly across channels.


Before you start, make sure your marketplace SKUs are aligned properly:


  • Every product must have a unique SKU.
  • The same product should use the same SKU across all stores.
  • Inventory linking should be done store by store.


You may also need to sync your marketplace products back into SiteGiant first if the listings were created directly in the seller center.


Steps to perform inventory linking


1. Ensure marketplace SKU alignment


Before linking inventory, make sure all marketplace store SKUs are properly tallied and unique.


This is important to ensure accurate inventory linking.


2. Sync back product if needed


If the product was created directly in the marketplace seller center and does not appear in SiteGiant yet, sync it back first.


Go to Settings > Sales Channel > Authorized Channel > (...) > Sync Back Product.


After the product appears in SiteGiant, continue with inventory linking.


Note: Inventory is not connected automatically after listing a new product. Whenever you add a new product or update product information directly in the marketplace seller center, you must manually trigger a product sync in SiteGiant and then perform inventory linking. Some marketplaces do not support automatic sync due to API limitations.


3. Go to Inventory Linking


Go to Inventory > Inventory Linking.


Select the correct Channel Store.



From the inventory linking page:


  • If the item is newly created and does not have an inventory item yet, click Insert. The system will auto generate the iSKU.
  • If the iSKU already exists, click Search to find and link the existing iSKU.


For pending or draft listings, edit the iSKU in the Draft Listing field and make sure the iSKU is correct.


5. Confirm the linking


Once the correct iSKU is selected:


  1. Click Confirm.
  2. Click Review Draft Listing.
  3. Click Confirm and Save Listing.


If a listing was linked to the wrong iSKU, check which iSKU is the correct one and relink the listing to that correct iSKU.


For TikTok listings, you can update the latest iSKU in the Draft Listing field. If the existing iSKU is wrong, click Reset and set the correct iSKU again, then confirm and save the listing.



To remove an existing inventory link for a specific platform:


  1. Go to Inventory > Inventory Linking.
  2. Select the Channel Store and find the item.
  3. Click Reset on the listing.
  4. Click Review Draft Listing (top right).
  5. Click Confirm and Save Listing (top right).
  • If a product is not linked to any inventory item, SiteGiant will not update the quantity for that product and cannot update the sold quantity to inventory.
  • If order fulfillment cannot detect an item, check whether the listing has been linked to an iSKU.


Orders created without inventory linking


If you create an order by using Custom Sale / custom sales item, the order item is not linked to inventory and does not deduct stock.


This is why a pre-order may be created successfully even when stock is 0, but it will not be inventory-linked afterward.


If you want the order to follow inventory linkage, add the item by using Add Product or Add Single Inventory instead.


Bulk order import cannot create Custom Sale items.




Note: Removing an inventory link means SiteGiant will no longer manage stock for that listing. This may cause stock inconsistency across channels.


If you want to reset all links for an entire platform at once, go to Settings > Sales Channel > Authorized Channel > (...) > Reset. Note that selective bulk unlinking (only a few items from one platform) is not possible — you would need to unlink items one by one.


Important notes


  • Inventory linking must be done store by store.
  • It is recommended to link the same item to one iSKU only for better inventory control.
  • If a product is not linked to any inventory item, SiteGiant will not update the quantity for that product and cannot update the sold quantity to inventory.
  • If order fulfillment cannot detect an item, check whether the listing has been linked to an iSKU.
  • Do not adjust stock directly from the marketplace platform (e.g. TikTok) after linking. Stock adjusted on the platform side will not sync back to SiteGiant, which can cause inventory discrepancies.



  1. Go to Inventory > Inventory Linking > select the Channel Store for Lazada > find the product > update the latest iSKU in the Draft Listing field. If the existing iSKU is wrong, click Reset and set the correct iSKU > Confirm > Review Draft Listing (top right) > Confirm and Save Listing (top right).
  2. Finally, go to Inventory > All Inventory Items > click the item name > Associated Products > Tally All Channel Inventory.


Important notes


  • Inventory linking must be done store by store.
  • It is recommended to link the same item to one iSKU only for better inventory control.
  • If a product is not linked to any inventory item, SiteGiant will not update the quantity for that product and cannot update the sold quantity to inventory.
  • If order fulfillment cannot detect an item, check whether the listing has been linked to an iSKU.
  • Orders created before an iSKU was linked will not automatically reflect the iSKU — the linking only applies to new orders created after the link is set.
  • A newly inserted iSKU in Inventory Linking is not created until you complete Review Draft Listing and Confirm and Save Listing. The iSKU will not appear in inventory until those steps are done.
  • If an order is not linked to an iSKU, stock adjustments for that order must be done manually via Inventory Adjustment or Stock In / Stock Out.
  • To avoid items not being captured with iSKU, regularly check Inventory > Inventory Linking > select Channel Store > Pending Action Listing and make sure no items are left without an iSKU set.



Unmatched Inventory refers to products that do not have inventory linking set up but have received orders from a sales channel. When this happens, SiteGiant creates an unmatched inventory record to log the sale, but stock quantity and history cannot be tracked for those items.


Unmatched inventory items do not appear in Inventory > All Inventory Items and cannot be searched or managed from there.


To prevent Unmatched Inventory issues, make sure every product listing has inventory linking set up before orders come in. If any listings are still unlinked, future orders for those products will continue to generate unmatched inventory records.







  • Bulk inventory linking
  • Sync back product from marketplaces
  • Link marketplace product with existing inventory item
