Inventory management, shopify sells too much

Hi All,

We are a fulfilment company and make use of fulfilment services in Shopify.
Most inventory management at our customers is managed by Shopify, whereby we update inventory once a day. During the day shopify is managing inventory.

For some reason, Shopify sometimes sells too much items. More than we have in stock. How is this possible? Inventory policy = deny as setting.

Hey! This sounds like a potential issue with delayed inventory updates, overselling due to multiple locations, or third-party app conflicts. I can help troubleshoot the root cause and suggest solutions to prevent overselling. Feel free to reach out!
