How do you manage your shipping, everyone?

I recently installed QBI, and USPS shiprush with Endicia. I'm totally new to Quickbooks.

I'm enjoying being able to print ALL of my shipping from home, (no more trips to the post office at 5pm! Woo!), but I find myself wishing I knew how to mark items as shipped efficiently.

In the past, before heading off to the post office, I'd check off items on a spreadsheet under a column labeled "shipped", then go onto my shop later on that evening to individually open each sale and change it's status to shipped, (or go to checkout.google.com for my google checkout orders, which automatically changes the zen cart order details to google shipped. Nice.)

Now that Quickbooks is available to me, I'm shocked at the lack of an option to mark an invoice as shipped! Or am I just thinking about this the wrong way? Am I forever doomed to the spreadsheet and cart method?

How do all of you keep track of what's gone out and what hasn't? Maybe, by sharing some of your ideas, I can figure out a way to do this all more efficiently. Thanks! :D
