We are trying to wave and batch pick thousands of shipments per day. The system will not allow us to print the labels until the shipments are confirmed, so we have a business event running that will autoconfirm the shipments after they have been picked. This allows the picker to print the labels and packing slips directly after they have picked.
The issue is the confirmation takes 30-45 seconds or more per shipment. so if we are batch picking 25 orders with the same product on them, it takes 10 minutes until the labels can be printed. There has to be something we are missing here - confirming a single shipment manually only takes a couple of seconds. We are using out of the box Stamps.com integration.
