Unable to Import Data for last year's Invoices with 8% GST, it prompts error of unable to create the invoices, no sure what's the problem?

Hi there, contact. I'm here to help fix the error so you can import your files into QuickBooks.

Sometimes, too much cache accumulated in a browser can cause unexpected behavior with the product. This can be the reason why you're getting the error message when importing your invoices.

I suggest running QBO in a private or incognito browsing mode. It helps your computer or device run optimally and regain some storage space to continue working seamlessly. See these keyboard shortcuts to open a private window of supported browsers:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

If it works, return to your regular browser and clear its cache. You can also use other supported browsers if the issue persists.
