Hello, everyone. I'm Jessie, and I'm a customer support representative. What are the most common causes of a 'QuickBooks script error,' according to numerous QuickBooks customers? A QuickBooks script issue might be triggered by a number of factors. Importing an invoice with account data that is different from assets or payables. It's quite probable that you're using an already-used login and password. If the QuickBooks data file is corrupted, any of these problems may arise. Script problems may also be caused by Active X components.
