A point of sales system is already in production in Drupal 7; people are using it and seem to like it. And now, we've ported it to Commerce 2 for Drupal 8. Check out this week's High5 to learn more!
What does this mean?
In Drupal 8, the POS is much more built in, and you can easily do things like change out widgets. So if you update your orders and you add a new field, the field will show up there. If you add a specific widget that controls how that field displays, you can pick from a list of available options and it will work in the POS.
How is this different?
In Drupal 7, the POS was very stand alone—it was all custom-built forms and custom-built options. You actually configured it outside of Commerce itself. It used some of the underlying parts of Commerce, but from a user perspective it was almost as if it was a separate module.
For Drupal 8, that's not the case. It has the same level of functionality, but it's integrated much more so you can use a lot of the Commerce infrastructure. For instance: Drupal 7 had the concept of locations (as in store locations), but Drupal 8 has the concept of stores built right in, so we just use that. There's lots of stuff that goes along with stores: you can attach addresses and extra billing information and so on, and the POS can take full advantage of that in Drupal 8.
Are there any new features?
We have quite a bit more reporting (such as KPI reports for tacking metrics for sales people, for instance.) We also have a new "quick add" section that lets you easily add common products without having to look them up by SKU—it's quite robust and fits nicely into the user interface.
When will all this be ready?
We're only at Alpha 1 right now. Alpha 2 should be coming soon. The module should be fully ready to go in the near future. You can download it's current state and follow progress here.
The bottom line
POS is finally ready for Drupal 8. You can start using it, and we're going to continue releasing new features at least once a month for the foreseeable future.
