I appreciate you for laying out the details of your concern, @kynethjane-kjabi.

I'm here to help guide you in the right direction to help you with the importing process into QuickBooks Online.

Please know that QBO depends on the data imported from the POS you've used. With this, I recommend contacting the Imonggo POS Customer Support Team. They can help you configure the integration settings and guide you with an accurate process. This way, you can import those bills seamlessly into QBO.

You can find their contact information on their page or website.

For future reference, I'm attaching this article with detailed instructions on exporting your reports to Microsoft Excel from QBO: Export your reports to Excel from QuickBooks Online.

Please don't hesitate to reply on this thread if you require additional assistance integrating data in QBO. I'll be right there to help you whenever you need it.
