What are inventory level updates?
For every e-commerce platform integration that is actively connected to your Spaceful account, Spaceful regularly and automatically tells the integration how many of each SSKU (Spaceful SKU) we have in inventory.
Specifically, this means that we take the available for sale quantity (as visible on the inventory details page for each SSKU) and then send an update for all of the aliases (SKUs, products, or listings on the integration) that belong to this SSKU.
Why does Spaceful send inventory updates?
Automatic inventory updates are good for you, the merchant, since they keep all of your integrations in sync with the inventory we have in Spaceful.
Keeping your inventory levels in sync is most important to prevent out of stock products — a situation where a customer places an order but there is no inventory in the warehouse to fulfill the order. If the inventory levels are fully in sync, then out of stock products are prevented because the listing will say "out of stock" and not allow the customer to place an order.
