Hello, ConorIB.
Thanks for dropping by in Community. In QuickBooks, the system only downloads up to the last 90 days of transactions, you can manually import data beyond the time limit. Download the bank statement from your bank using the following supported formats or file types:
Once the bank file is ready, start importing the file to your QuickBooks Online company. You can refer to this article for more detailed steps and the process: Manually upload transactions into QuickBooks Online. Then, you can categorise and match the transactions.
Feel free to shoot comments below if you have any other concerns or questions about bank transaction. I'm always glad to help in any way I can. Take care!
