Does not import existing customers - it pulled in some, but only about a quarter of my existing customers. Further it does *not* import any existing orders from your Magento store. It will only sync new orders after you configure the plugin.
Finally, the plugin is poorly written (no comments in any of the code, little to no logging, did not connect to the SuiteCRM with the provided api keys, etc) and the developers are difficult to reach if you are in the US. Only after burning a week working with the developers to get it sort of working on our server, they informed me that if I wanted all my existing customers and any of my existing orders imported, I'd have to hire them at an hourly rate for extensive customization.
No thanks, moving on to something else. View Add-on
