Thanks for getting back to us, @Itryon,

We want to make sure you're able to correct your books. When you delete transactions within the program, any balances from that entry will no longer be counted on the reports.

Any prior reconciliations are also affected when deleting transactions. This will remove the balance entirely which is why this process is needs to be done carefully.

Also, since you mentioned these entries are from previous years, we highly recommend consulting with an accounting professional before any corrections. This way they can advice if you need to delete or make adjusting entries instead.
