First, I'd recommend you compare gain and loss by stock and by sale date to see if you can narrow down the reason for the difference.

Once you find the stock causing the problem, go to Accounting>Investments and click on it's name. That will open a list of all the transactions you've entered in bivio for the stock. Go through each of them and make sure what was entered in bivio is correct.

If you find a problem and don't know what to do to correct it, email us the specifics of your question ( including stock ticker, transaction date, problem you see) to support@bivio.com.
