We are using Cin7 to process orders before it goes to ShipStation in order to print the postage.
I want to print the packing slips from Cin7 in order to smooth process out. once the order is then picked via Cin7 and it send the order over to ShipStation to save paper, ShipStation should then recognise the transaction/order barcode in the scan to verify pack module.
So you would be able to scan the packing slip that Cin7 has generated.
