You can easily remove estimates that have already been importing from the queue. This would only happen in a very odd circumstance, like Internet going down.
- Go to the Quickbooks menu in the grey dropdown menu in LMN, then choose Quickbooks Export.
- When that screen loads, click the EXPORT QUEUE tab. That will show the estimates 'stuck' in the queue. Just hit the DON'T EXPORT button to remove them from the queue.
