Saving time in managing returns

Hi all,

We have to return a few orders a day. Right now we do it manually: authorize the return, buy label (usually cheaper this way), convert the pdf label to jpeg label and attach it, and then finalize the return authorization. This is extremely tedious and take a lot of time. So, I was wondering if there is an app to help speed up this process. I googled and ReturnGo app popped up, but with zero review on Amazon platform. Any suggestions are greatly appreciated. Thanks!
