Hi,
I did open your QuickBook Database and saw several tables (accounts, bills, companies, credits, customers, employee, invoices, purchases, sales, vendor ,etc).
Using that database, I can propose several graphs and reports (sales per customers, vendors, per company, per accounts or invoices per companies, per customers, etc..)
However I need you to describe your exact business needs and tell me if you want me to connect power BI with Quickbook online.
FYI, I am a senior BI consultant with over 3 years experience with Power BI and I can help you to build your reports.
I will create a beautiful, dynamic and user friendly dashboard and will provide the pbix file at the end of the project.
Regards,
