I have a client that is switching from customized software for Construction Project Management to Smartsheet and is hoping to preserve his ability to have a back-and-forth (or one-way) integration with QuickBooks Desktop. The previous software was using Intuit's QuickBooks Web Connector to integrate the two applications, but as far as I can see that Web Connector is incompatible with Smartsheet.
I am hoping to see if anyone has any experience connecting the two applications via API or some existing third-party application. API Integration is outside of my scope but I want to be able to push him in the right direction.
Thank you for any advice you can offer!
