I would also give this ZERO stars if I could. They provide the worst customer support. Even if you write in, they will not answer.

I use Shippo strictly because I need USPS manifests for when the mail carrier comes to our shop, so they don't have to scan a couple hundred packages. That said, I have 3 complaints with the system. 1) Their developers roll out changes to the application without testing....so you will be in a groove, needing to get shipments out and boom...something that has historically been working is not working now. It's usually resolved within the same day, but probably about once per month something is magically broken. Users should not be finding these issues EVERY time. I wish that there was more testing done before pushing production changes. Especially when core functionality is what is affected. (i.e. today, cannot print labels for batch orders, the button does not work). 2) Every now and again, the sync between Shippo and Shopify gets broken. We use a different app to print picking lists, and then use Shippo to print our labels only. So when shippo doesn't fulfill an order or two in Shopify, you have to work your way back and figure out which order didn't fulfill. 3) If you have a non-technical person printing labels for you and the process needs to be the exact SAME every time, do not use this application. Sort of tied to complain #1, there will be application changes rolled out that affect browser functionality. Like, I used to be able to print labels and manifests from Safari...but that stopped working, and now you have to save the file to your computer, find the file, and print from the local file. We switched to Firefox and the functionality works fine. There are various little things that pop up that I figure out how to navigate around, but a non-technical person would not.

I don't know the age of the company, but the application feels half baked at times and it seems like Shippo is a start up company low on resources and formal processes...no knock on that, but when your business relies on their application, it's a no-go.

If I could give a No Star rating I would. This company is not to be trusted. We installed the app to see if it was of any use to our Shopify store. It wasn't so we un-installed it within an hour. We have had 2 payment requests from them since. We contacted Shippo after the first and was told that it was fixed. We have now received another bill for a service that we have never used and never will. Shopify state that after an app is un-installed the developer should delete all of our data, etc. NOT send the end user a bill.
