StarShip supports write-back to several fields in QuickBooks Online. These fields are not mapped by default so if you want shipment values to write back to QuickBooks, you should set up these field maps.
To access Custom Write-Back Setup, go to Setup > Source Interfaces > QuickBooks Online > Interfaces and select the Customize Interface button for a QuickBooks document (Invoices, Sales Receipts).
StarShip will update the “Shipping date” on the Create Invoices or Create Sales Receipts screen with the value from the StarShip field when a shipment is processed.
You would most likely map this field to the StarShip “Ready Date” field.
StarShip will update the “Ship via” on the Create Invoices or Create Sales Receipts screen with the carrier you choose when a shipment is processed. You should map this field to the StarShip “Ship Carrier Name” field.
StarShip can write back to the three Custom fields that are set up in QuickBooks Online. See Custom Fields for more information.
