We really would love to see the ability for these local deliveries to be marked "delivered" by our delivery driver, so that our staff can see the timing of delivery, and the customer can receive a delivery confirmation, like they do when amazon or any carrier delivers. My drivers currently have a google sheet with their route and enter the info (time of delivery, who it was left with, etc) in the sheet. My customer service team manually checks that multiple times a day and sends "your order has been delivered" emails manually to customers. Takes a lot of time. Would be infinitely better if our drivers could use Shipstation to just mark an order as delivered.
We have the same scenarios. We change the carrier to "other" in the listing and for tracking number type in "customer pick up". Seems to work for us.
The inability for the user to edit the carrier list for the "mark as shipped" function is a major oversight. Many of the major carriers (like freight, particularly) are not in the list. I'd also like to be able to add them, or at least have a "blank" option where I could type in one that isn't in the list for a particular order.
This would be very helpful!
