For us Shopify and the others of the like just aren't setup really anything like the Intuit Pos system at least for us with work orders and such, let alone the syncing function. Kinda hard to step backwards in functionality. 

We had a proposal presented to us from Heartland POS, seemed salty, 4400 ish set up and 450 a month after that versus just deal with a little cumbersome CC stuff. 

Thankful we never went away from QB intuit desktop accounting or we would be in a different boat.
