Splitting payment for an office supply order

Hello there, @LouBergner. I'm here to help you split a supplier payment between two accounts in QuickBooks Online (QBO).

To achieve this, you can create two payments for the order using your checking account and gift card. This will let you split the payments. Let me guide you on how:

1. Select the +New button and choose Pay bills. 
2. In the Payment account field, select your Checking account.
3. Then, check the bill you need to pay and enter the amount.
4. Once ready, select Save.
5. After that, pay the remaining amount using the Gift Card. If you haven't created an account for this, simply refer to this article for the steps: Add an account to your chart of accounts in QuickBooks Online.
6. Next, follow steps 1 to 4 and ensure to select the Gift Card in the Payment account field along with the remaining amount to be paid.

QBO also works with Online Bill Pay which gives you the option to pay your bills online. For more info about this, feel free to check this link: Pay bills in Online Bill Pay.
