Welcome to the Community, @Kamprod.

You can merge your bank accounts and use the name and account number of the account you want to keep. All data moves into the account you want to keep and removes duplicate transactions. Before we proceed with merging, make sure to save reconciliation reports of the account you are merging. Please note that once you merge bank accounts, you can't undo them.

Here's how:

1. From the left menu, select Accounting.
2. Choose Chart of Accounts.
3. Locate the account you want to keep. Then, click the drop-down arrow next to View register and select Edit.
4. Take note of the account details and click Cancel.
5. Look for the account you want to merge. Then, click the drop-down arrow next to View register and select Edit.
6. Change the duplicate account's info to match the account you want to keep, and click Save.
7. When you're ready, select Save and then Yes, merge accounts.
