Hey compmore1,
You’re right that you’ll need to roll into the 2025 financial year before you can run the September BAS. If the Start New Financial Year process keeps freezing at the same point, that usually indicates the file is carrying more data than Accounting Plus v18 can comfortably handle during rollover. A practical way to resolve this is to reduce the file size first by purging older transactions you no longer need in detail. Once the file is lighter, try starting the new financial year again and it should progress as expected.
Cheers,
Doreen
