Hi there, saurabhgupta.
I'm here to make sure you'll get the help you need by routing you to the right support.
When it comes to integrating ERP into QuickBooks Online (QBO), it'd be best to contact their technical support since it's a third-party application. Any concerns about syncing or integrating the third-party software into your Online account are best handled by their support.
You can also export your data to Excel to help give you the flexibility to use them. Simply click the Export icon and select Export to Excel.
Keep in touch with me here should you have any additional questions or concerns. I'm always available to help.
In addition to Fiat Lux - ASIA's suggestion, you can explore the QuickBooks Online Apps menu to search for an application for importing data to integrate it with QuickBooks Online.
For detailed steps and an overview about importing data, you can reference this article: Move your Data into QuickBooks Online International.
Let me know if you have additional questions about getting your data to the platform. I'm always here t help. Have a good one.
