Our company is currently using both Shopify and Toast separately. Is it possible to integrate the two?
If so, how does it work?
Thanks!
To my knowledge, Shopify integrates with POS systems like Toast, but you might need a third-party integration app. However, from what I read on the Shopify blog, the process comes with limitations and might cause some issues (inventory data not syncing in real-time, for example). Of course, there might be a way to work around these, but unfortunately, I am not familiar with them. I hope I gave you a direction for your search, which is most likely finding a third-party system that suits your needs.
We have retail and a deli and are thinking of adding Toast but are so unsure. What has your experience been so far with having both systems?
Do you know which apps will connect the two?
Did you already manage to find out? 
We never have found a solution
Just found this. Not sure how useful it is but might be worth a try. Let us know what you discover.
