Works great! I copy and paste the order numbers and tracking info from my dropshipper's email's and put them into a google spreadsheet, then massfulfill does it's thing perfectly.
Now I just need an app that will automatically pull the info from the emails and put it into a spreadsheet!
Team boltics you should make one!

Great app for automation, we use it alot at www.diamondhomeusa.com for thousands of orders

Brilliant tool. Simple to use and it saves me countless hours a week and has never given a problem. I highly recommend it to anyone who's copying and pasting tracking numbers into shopify.

very helpful for VA's specially when fulfilling huge amounts of orders. Great App.

Incredible app, very efficient! HIGHLY recommended if you are putting a higher amount of orders daily.

amazing app woohoo amazing a+ woohoo amazing a+ woohoo

Great App. Thank you for building it.

I don't normally write reviews and i MUST say this is one of the simplest and most easy to use app I have found here and it has saved me tons of time. The work I used to hire people to do now gets done within 10 min. And the support is very helpful and responsive as well. Thank you so much!

My subscription business (www.bokksu.com) has grown large enough that we've outsourced the fulfillment to a third party warehouse, so we desperately needed a way to fulfill the orders in my Shopify admin with the appropriate tracking numbers. Thankfully MassFulfill does EXACTLY what I was looking for and best of all is FREE. I highly recommend using this app to save yourself hours and hours of time of having to manually input each order's tracking number/fulfillment! Thank you very much Boltics!

Literally a huge time saver, thanks team.
