A handy feature for source stores, to protect against oversell.

Note: Synced Stock Buffer is a Shopify only feature for now. The buffer does not apply to products synced to other platforms such as: WooCommerce.

What does the Synced Stock Buffer do?

The synced stock buffer allows you to hold any number of stock as a reserve as protection against oversell. Without the buffer activated, Syncio will sync all available stock according to your inventory location settings:

Here's what happens when you set the buffer:

Notice how Syncio sets aside 5 quantity of the blue shirts in reserve? The effect is:

  • All 40 shirt are still available on the source store.

  • But any connected destination store will only have 35 available to sell.

  • 5 qty is kept as a reserve at all times.

Why should I use this feature?

Syncio processes orders in real-time as soon as they are created. However there may be situations where keeping some stock as a reserve can be useful.

  • Protect against a stock miscount in the real-world.

    • Example: a product is stored in the wrong location at the warehouse, and therefore not available.

  • Protect against heavy sales or network traffic.

    • You may have noticed or heard of situations on your store where things may be a bit slower than usual.

      • During a sale period: lots of customers are shopping.

      • When you are doing a bulk update of products or settings:

        • Example: uploading a CSV file or using a third party app to make hundreds/ thousands of changes.

    • Heavy activity such as the above may affect syncing speed which results in a delay of the sync. Potentially leading to an oversell situation.

  • Protect against network outages.

    • Although very rare, software and apps may experience connection issues.

    • For example, there might be an issue with your payment processor delaying payments.
