Yes, Simply will support BC deployed on-premise. Please refer to supported versions of Business Central.
The following configuration is required to support BC on-premise.
- The ERP API Base Url must be publicly available and secured with a valid SSL certificate
- The APIs use a different port (default 7048) than the BC Client. Traffic on this port will need to be allowed through your firewall to the BC server
- Only OAuth is supported (Basic Auth is not)
- The BC APIs are not enabled by default and need to be enabled
