We just shipped v10 of @Shopify POS. Major redesign. Faster. Smarter. And built for selling in person, your way.

Here are the headlines:
- Branded POS screens
- New home screen layout & navigation
- Redesigned cart
- Smarter, faster search

Fewer taps. Cleaner workflows. More control.

If you’re not already selling in person, there’s never been a better time to start.
