Common alerts/errors

Take a look below for a list of common errors and how to fix them.

Failed to sync inventory for [Product name].

Reason: The product may not exist, may be deactivated, or may not have a matching product name/SKU in either inFlow or Square.

Solution: Ensure the product exists on both the inFlow and Square sides with a matching product name.

You have duplicate product/variation name(s) in Square.

– OR –

You have duplicate product/variation SKU(s) in Square.

Reason: There are multiple copies of the same products with the same name or SKU in either inFlow or Square.

Solution: Remove or rename the duplicate products/SKUs in both inFlow and Square, then resync from the inFlow integration settings.

Product details push failed for product.

Reason: Selecting Push now to sync products while inFlow is already pushing product details to Square can cause this error.

Solution: Your Square products are still syncing. Try again shortly.

The item ‘[Product name]’ was not added from the Square catalog. Orders containing non-catalog items cannot be synced to inFlow.

Reason: Most likely, the item was added to the order via the API or outside of the Square product catalog. Orders containing non-catalog items cannot be synced to inFlow.

Solution: If the order is already completed in Square, it cannot be updated. Please recreate the order in inFlow, as it will not be pulled automatically, and then dismiss the error.
