How do products map between WooCommerce and QuickBooks?

We map the product SKU to the QuickBooks item name

Product Variations

Each product variation has must have a unique SKU in WooCommerce. The variation is treated as its own product in QuickBooks. If the SKU has no matching item name in QuickBooks, then our software makes a new product. The variation SKU will be the item name. If the SKU matches an existing item name, then the software will match to the product.
