Thanks! So the first thing to do would be to reconcile your account, which is where you match a date range on QuickFile against a bank statement.
There’s a guide on how to do this, here: Reconciling your bank
If you start with the statement range and work your way down, this will help identify any issues.
So for example, start with 1 month and an error is picked up, narrow it down to 2 weeks, then 1 week and so on (depending on how many transactions you have, you could narrow this down further).
It’s just the case of inputting these missing transactions into your account from there.
