Sage MAS90 Integration x Shopify by Maria Catapano

I'm looking to integrate our store to Sage MAS90, which currently manages our inventory and sales orders.
I've done some searches but can't find much info online on the cost and/or logistics of integrating the two. I would need quantities to update automatically (approx. once a day), and orders to be automatically feed from Shopify to MAS90 (to avoid manually inputting the orders).

Any insights are appreciated. Thanks!
