Billing with Quick Books from SS

I am currently setting-up Smartsheet to handle; inbound order receipt/processing, production tracking, and inventory management for our company however, the billing section is causing me some problems.

The goal is to bill via Quickbooks: what is the best way to export the row data (PO Data) to Quickbooks for invoice processing without exporting unnecessary columns? Then how is it best to upload the QB data to SS? I want them to "talk" to each other with minimal manual interaction to avoid human error where possible. Thank you!
