Our business is retail. How do I account for funds our POS system automatically deposits to my checking account

Thanks for visiting us here today, @mcdargen.

I have some information about recording your POS funds. If you've created a sales receipt in QuickBooks for the retail, you can match it with your POS deposit. If not, you'll have to enter a sales receipt in QuickBooks. This way, your funds will be recorded accordingly.

To match:

1. Go to Banking, then select Banking.
2. Pick your checking account.
3. From the For review section, mark the deposit or payment to open.
4. Tick the Find match radio-button and look for the sales receipt. 
5. Click Save.

If you're unable to find a match, you can tap the Add button to create. Refer to this article for more information: Categorise and match online bank transactions in QuickBooks Online.

Here's how it looks like in the banking section.

Additionally, here's a link that covers all the tasks you can do when using the banking feature.

Feel free to let me know if you still have questions or concerns with your account. I'm more than happy to assist you further. Take care and have a great rest of the week.
