Information for Troubleshooting Inventory Sync Issues in NetSuite Connector

Following are some important points for inventory and quantity fields:

Inventory syncs to the storefront and not from the storefront. Therefore, you should never expect to see inventory syncing back to NetSuite, though the items that appear on the orders through the order sync affect inventory.
Inventory syncs from NetSuite are not instantaneous. Though most of the connectors support real-time price and quantity sync, syncing them can take a few minutes. This time depends on other processes running in the storefront, connector, and NetSuite. If you are not using real-time price and quantity sync, then the sync runs only once in an hour, by default.
When syncing inventory from locations in NetSuite and not to a custom field, NetSuite Connector syncs the quantity available and not the quantity on hand. Quantity on hand includes everything you have in the warehouse, including quantities already committed for orders. Available quantity is the amount of inventory in the warehouse that has not been committed to orders and is therefore the actual available quantity to sell.
