When I ended up with a last-minute order from a customer in Florida who needed the items to arrive in time for Christmas, I started checking the computer obsessively to see where the package was. I started wondering if there was a way to track packages from my iPhone....and yes, there was.
USPS Mobile (no, they're not paying me) has apps for the iPhone, Android, and Blackberry phones. You can scan the bar code or type in the tracking number and see where your packages are. It also connects you to USPS resources, post office locations, order supplies, schedule pickups, and calculate shipping prices.
Thankfully, the package arrived in Florida in plenty of time to be wrapped and placed under the tree. This is such a time-saver for me since it connects so quickly and gives me my answers without having to hop all over the Internet. My iPhone has become my favorite business tool, using the USPS, Etsy, Square, and Paypal apps along with my email. Are there other great apps out there that I've missed?
