This is truly a great app. I upload manny tracking details all at once. i read the FAQ and found an even faster way of uploading.. what used to take me hours now only takes about 3 minutes.. this is a life saver..

No complaints whatsoever. The user friendliness when using this app is on another level. Other SaaS applications need to look to MassFulfill, as they have created an app that saves a ton of time and is super easy to use. On top of that, it's free. If you're entering tracking numbers by hand you're doing it wrong!

Bulk updating shipping info is a fundamental feature for us, yet it's missing from Shopify. Fortunately, there's MassFulfill. It's worked flawlessly. And we really appreciate that Boltics has made this app free. Thanks so much this terrific app!


Our warehouse software crashed and we had to manually input tracking codes. This saved the day. Thank you!


So great! And it's free!
Must have this App.

Had some initial connection issues with our API connection to our fulfillment house and found this tool to update 600+ orders with the correct tracking information in less than 15 minutes. Extremely pleased with how easy it was.


Perfect tool! Saved me a lot of times!
