Easy-to-use app that's a must if your business tracks serial numbers. A surprise bonus feature we use all the time is the order printing templates, which not only allow us to show the S/N on the receipt but also produce a much better looking and more customizable receipt than the native Shopify order print function. Last but not least, I ran into a snag when I installed another app that apparently conflicted, and Giedrus found and fixed the issue extremely quickly. Great support!

One app, this app, upped my client's store to the next level. Adding serial numbers to each and every item sold and attaching it at the order level. Plus, a VERY-robust documentation and API reference to be able to fetch that data from anywhere. I am not exaggerating when I say "you can't ask for anything more" but you literally cannot ask for anything more: robust App, documentation, support channel, developer channel, API, API documentation. This App is Enterprise grade. We ended up rendering the serial numbers on the INVOICE as well and the packing slip and the order notifications and fulfillment SMS so the whole experience was completely amplified to a new level....all due to one app. This app.

does exactly what it says, enables use of serial numbers and tracking along with guarantee expiries, why this app has never been created up to now is anyones guess, for some like myself its a necessity - highly recommend - do not judge by lack of feedback, its new!
