BigCommerce Inventory
BigCommerce Connect can update Inventory for BigCommerce Products in real time. This lets your BigCommerce know a product is in, when received, or out when sold.
Set BigCommerce to Track Inventory on the Product Level to use the value posted. Then, use Upload in Items Search to link the Item in BigBusiness to BigCommerce.
Linking relies on the SKU of the Product being the Item Code from BigBusiness and does not work for Variants. Once linked, updating works as expected using settings.
BigCommerce Uploading
BigCommerce Connect 3 can update Inventory for BigCommerce Products in real time. Upload one time, and BigBusiness will get the BigCommerce ID for posting new Qtys.
In Connect Settings for BigCommerce choose Link-Only for Update Products. Then, in Items Search select some items and click Upload. Wait for Success! and you're set.
Once the BigCommerce ID is set on the Item, any change will update BigCommerce. This uses Auto-Connect, Update Availability, and Update Product Pricing settings.
BigCommerce Link-Only
BigBusiness can Update Availability for BigCommerce Products when you buy or sell.
In the Company Card, BigCommerce Settings, for Update Products choose Link-Only. For Update Availability choose Qty On Hand or Qty Available which deducts Orders.
Use Upload on an Items Search and Link-Only will set selected items to be updated. Then when you enter an Order yourself, BigCommerce will get the new Qty Available.
BigCommerce Variants
BigBusiness can Update Availability for BigCommerce Variants when you buy or sell.
In the Company Card, BigCommerce Settings, go to Advanced and click Use Variants.
This works with BigCommerce Products set to Track Inventory On The Variant Level. Set the SKU of the Variant to match Item Code and use Link-Only for Upload to link.
BigCommerce API
BigBusiness 15 automatically switches the BigCommerce API for different functions. This provides backwards compatibilty while offering new functions like Use Variants.
