Code: DUPLICATE_SKU

SKU already used by another product on the Cloud

What it means

This till created a product whose SKU another product already holds on the Cloud, so the Cloud refused the product. Nothing was written on the Cloud, and this product's sales wait until its SKU is fixed.

Where it appears

Desktop: Sync Center → “SKU conflicts”. On the web it also appears as “Duplicate SKU” in an import report.

Likely causes

Two tills created products with the same SKU before syncing, or a hand-typed SKU matches an existing product's.

Safest actions

In Sync Center → “SKU conflicts”, enter a “New SKU” for the product. The product and its sales are sent again automatically. This conflict can't be dismissed: it is resolved only by changing the SKU.

Permission needed

Changing the SKU needs permission to edit products.

Safe to retry

Yes

When to contact support

Contact support if the conflict stays after changing the SKU and syncing.
