Serializer ‑ Product Tracking

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.
