Good day, everyone. My name is Jessie, and I work as a customer service agent. According to multiple QuickBooks customers, what are the most prevalent reasons for 'QuickBooks script error'? A QuickBooks script problem may be caused by a variety of things. Importing a payment invoice that has the account information that is not the same as the assets or payables. It's quite likely that you're using a login and password that has previously been used. Any of these issues might occur if the QuickBooks data file is damaged. Active X components may potentially create script difficulties.
