ShipStation

It does a good job for printing labels. The only thing that is not good is printing the pick list. You can only download as a pdf and can't sort.

So far so good! We've been using ShipStation for about a month, and the warehouse loves it!

A rep from shipstation called our business to discuss features they are working on. Sounds promising.

*UPDATE JAN 2016*
In 2012, Shipstation was cutting edge. I think they stopped working on major features in 2014. Now looking at alternatives.

If you run a small business and need a pure shipping solution, shipstation is still a winner. If you need expanded functionality (barcodes, inventory management, etc), look elsewhere

AUG2012 review: Good product. Much better features than the other option on shopify. Def still some bugs though, especially in the automation rules... however, support has been responsive.

Very easy to set up and train people quickly. The Integration into Shopify was very quick and simple and has no down time.

We love ShipStation! Very user friendly, and has helped streamline our order fulfillment. Highly recommend.

After nearly a year using ShipStation, I have to say we are quite satisfied overall. While not perfect - there are a few minor bugs here and there - I would definitely say its outperformed all of the other options we'd tried in the past. Absolutely love the built-in scan verification feature for packing orders as it has decreased our fulfillment error rate by over 98%. We've also had no issues with getting in touch with live chat or phone agents who have been able to help us with whatever issue we've encountered.

We made the call to switch to ShipStation when drop shipping use to take up half of our day. Not only have we seen a severe decline in the daily hours needed to ship our products, but we know that as we grow, ShipStation has our back.

We've been using ShipStation for a year now and have had no issues. Does exactly what we need. We were easily able to find the answers to any questions we had.

Overall great as it pulls in orders from many different stores / platforms. The inventory tracking doesn't seem to work, but otherwise great.

I've been really happy with ShipStation so far for my small business. It was immensely helpful during the busy holiday season being able to batch process and prepare orders to ship. As I add more product lines in the new year I can only see this app becoming more and more useful to my business.
