How do I split the expense allocation when making a cheque payment?

Welcome to the Community, El.

I am here to give you information on splitting allocation when making a check payment in a QuickBooks Online (QBO) account.

When creating a check, you can enter multiple expense accounts to split the payment. You can view your created expense transaction on the Expense page. 

Here’s how:

1. At the left panel of your QBO account, click + New tab.
2. Select Check under Vendors.
3. Type in the necessary details for your check. 
4. On your Category details enter the accounts that add up with the Total amount of the transaction. 
5. Once done, click on Save and close.

QuickBooks will automatically create it as a split payment. However, when you’re going to pay the bills, the transactions will not appear as split but as a whole. 

When you're finished creating your check, you might want to read about categorizing your bank transactions in QuickBooks Online.
