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 youβre not already selling in person, thereβs never been a better time to start.

The most important story of every business is the one about _why_ it exists. Pulling this story out of a business is hard to do well. I challenged our team to try anyway and I love what they came back with.
*This* is why Shopify exists.

This was a fun shoot to take part in at work. Reverse AR is mind-blowing and it was amazing to get an early view into how the team at Shopify built this. Watch part 2 for my Oscar-worthy acting when the room moves: x.com/StrangeNative/status/1β¦

A great perk of my job at Shopify is support for continued development: Buy a book and expense it if it helps you grow in your role. Iβm stepping into my next role at Shopify and got this book recommended and an hour into it, itβs already proving to be super insightful.

Itβs been super fun to learn some basic 3D modeling for my home improvement projects and last night I finished modeling my back yard. From this template I can scope work I want to have done, including a fence, some decking, additional furniture and other ideas to make it great!
