I am integrated with Quickbooks and treat fees as expenses, which means they do not affect my "Crypto asset account", they are posted to a Fees account.

I can never reconcile the balance of my "Crypto asset account" with the "Cost basis" shown on Koinly on any given day, because the Koinly calculation automatically adds trading (but not transfer) fees to the "Cost basis" figure it displays.

To be clear I am happy with how the Quickbooks integration works, the issue is with what Koinly is showing, as there is no option to trading treat fees as expenses on Koinly instead of including them in the "Cost basis".
