We use SAP for accounting. As part of our new implementation for Shopify, we are planning to use the Shopify settlement functionality based on the delivery documents from SAP. Shopify generates the invoice for the delivery (partial or full) and settles using its native settlement functionality. SAP generates the invoice after the delivery documents interfaced with Shopify. How can SAP and Shopify reconcile invoice and settlement amounts? Also, how do other Shopify customers handle reconciliation between Shopify and SAP?
