A client asked us if it's possible to have the products on their website integrated with Sage Evolution so that when products are purchased online by users the stock values on Sage Evolution will be updated as well. The client would like this to be integrated with their existing WordPress site.
From what I've found so far, I don't think there's anything already available to use with WordPress except the SagePay through WooCommerce plugin. I'm not quite sure if this connects to a Sage client and updates the stock as well.
I found a Sage Evolution SDK that can be used but I doubt the client would buy with that kind of fees. There's also the SData api which I found here: Integrating with Sage Financial Software.
I'm not sure if you can use SData with Sage Evolution.
I would appreciate any help on this, thank in advance :)
