I am entering checks in quickbooks online. I want the expense account for the vendor to automatically load everytime that vendor is entered. Can this be done in online?

Certainly, I can help you with that, @dap5.  

Setting up default expense accounts for your vendor in QuickBooks Online (QBO) is a simple process. You can do this by editing your vendor details and assigning the expense account as your default expense category.  

Here's how you can do it:

1. Go to Expenses and select Vendors.
2. Choose a vendor you want to link to the expense account.
3. Click Edit to open up their profile.
4. Under Accounting, you'll find an option to set a default expense account. Choose the expense account you want to link with that vendor. This account will automatically load whenever you enter transactions for this vendor.
5. Lastly, make sure to hit Save to lock in your changes. 

After that, QuickBooks Online will automatically assign the appropriate expense account for this vendor, simplifying your tasks.
