For years, the sales tax manually entered in an estimate was carried over to the invoice when using the feature to convert an estimate to an invoice. Sometime around June, QBO made a change that now overrides the sales tax amount entered manually in the estimate by recalculating the sales tax. If QBO's calculations were correct for everyone, then there wouldn't need to be a way to manually enter the sales tax, but there is. Please go back to the way it was when the manually entered sales tax amount was properly carried over to the invoice. This change was made without any warning and already cost our business thousands of dollars in sales tax and now makes it an error prone process to workaround this bug. Thank you.
