How do you link a bank a blunt and what’s is the advantage

Thanks for posting here in the Community, @jcgreenbuilders. 

Here are the advantages in linking your bank account to the program: 

• The online banking feature allows you to automatically download your recent transactions.
• You can get an up-to-date view of your sales and expenses without manual data entry. 

I’ll guide you through the steps on how to connect your bank account. 

1. Go to Banking from the left menu. 
2. Select Add Account at the upper right. 
3. Enter your bank name or URL. 
4. Click Continue. 
5. In the pop-up window, enter the login credentials you use for your bank’s website. 
6. Choose the account type you're connecting (savings, checking, or card).
7. Set the date range for the download. 
8. Click Connect.

You can go through this article for more detailed steps: Connect Bank and Card Accounts to QuickBooks Online. 

Once downloaded, all you have to do is to approve the way the program categorises the transactions. Then, you can match them against the entries in the system. To learn more about this process, check out this article: Assign, Match, and Categorise Your Bank Transactions. 

I'm just a post away if you need further assistance. Have an awesome day, @jcgreenbuilders.
