How should I import the relevant sales and purchases data into Quickbooks and generate the reports from the imported file?

I can share some details to import your sales and purchase data in QuickBooks Online, @sleep.easy.sg.

You can import your sales as invoices and purchases as bills in QuickBooks Online (QBO) by uploading it as a CSV file using Excel. This way, you'll be able to see your reports from the imported file like the Profit and Loss, Balance Sheet, Accounts Payable, Accounts Receivable, and more.

Alternatively, you can utilize third-party applications that can integrate with QBO. For more details, take a look at this window: https://app.qbo.intuit.com/app/appcenter/findapps.

I'm adding this article as your start-up guide created by our Community moderator: Move your Data into QuickBooks Online Singapore. This includes other data that you may want to import into the system.

Let me know in the comment if you have other concerns with importing data. I'm always around to help. Stay safe and well!
