Hello there, JayM10,
The data showing on your QuickBooks Desktop file will depend on when you have started using the software. And, the time you've recorded those transactions to keep your books accurate.
I suggest contacting your bank so they can provide 8 years of entries. This way, you'll be able to obtain the balance you need for your charity's accounts.
Once you have the data, you can export reports from QuickBooks to Excel. Then, combine your entries from there.
Stay in touch if you need additional information. I'm always around to help.
