I would like to explore the integration of our Shopify sites and our Sage accounting system. Could you please let us know more about this such as integration capabilities, including any existing connector’s or applications.
Hello Ken Kishida , so glad to see you participating in the Sage City Community!
Sage 50 can work with several other programs developed by third party Sage Development Partners.
For a full list of our partners that provide third party solution that will work with Sage 50, please click here.
Please Note: Because Sage Marketplace applications are developed by third-party vendors, please send inquiries directly to the vendor, this includes any questions about your Shopify sites integration capabilities, including existing connectors and or applications .
Sage 50 does not support or troubleshoot any of the listed third party solutions that are available.
It is recommended that third party solution providers that are not a certified partner, sign up for the SDK at https://www.sage.com/us/partners/development-partners-erp-crm-hrms.
I truly hope this information has been helpful.
