QB Point of sale is putting cash sales transactions into the bank account

Hello there, jengebhardt.

I'd like to share some information about the process in taking payments in QuickBooks Desktop Point of Sale.

You're right. Checks, credit card, and debit card transactions are placed in the Undeposited Funds account. On other hand, Cash payments from QuickBooks Desktop Point of Sale are placed by default in the Cash In Drawer account.

That being said, once the financial exchange was done, you need to transfer the funds from the Cash In Drawer account to the Undeposited Funds account 

Like this:

1. Go to the Banking menu.
2. Choose Transfer Funds.
3. From the Transfer Funds From drop-down, select the Cash in Drawer account.
4. From the Transfer Funds To drop-down, select the Undeposited Funds account.
5. In the Transfer Amount field, enter the amount of money you want to transfer.
6. Click Save & Close.

Once done, you may now deposit the amount that was transferred. 

Here's how:

1. Go to the Banking menu.
2. Choose Make Deposits.
3. On the Payments to Deposit window, select the transferred amount along with other payment/s to deposit. Then hit OK.
4. On the Make Deposits window, select the bank account to which the funds are being deposited to.
5. Select Save & Close.
