Reconcilliation- major differences

Welcome to the Community forum, @DylanHouse.

You'll have to review and deposit the transactions from your Undeposited Funds first before you reconcile your account. This way, it will match your bank records.

All payments in the Undeposited Funds account automatically appear in the Bank Deposit window. To make a bank deposit, you can follow the steps below:

1. Select + New.
2. Select Bank Deposit.
3. From the Account ▼ dropdown, choose the account you want to put the money into.
4. Select the checkbox for each transaction you want to combine.
5. Make sure the total of the selected transactions matches your deposit slip. Use your deposit slip as a reference.
6. Select Save and close or Save and new.

For more details, see this article: Record a bank deposit and combine the payments in QuickBooks.

Once everything is match and categorise, you can now perform a reconciliation. Here's how:

1. Select Accounting from the left menu. then Reconcile.
2. Click Get started to continue.
3. From the Account ▼ dropdown, select the account you want to reconcile. Make sure it's the same one on your statement.
4. Review the Beginning balance and enter the Ending balance with the Ending date on your statement. 
5. Once ready, select Start reconciling.
