In Quickbooks Online how do you assign or match part of a spilt transaction to an invoice that's been paid? Having trouble doing this when it's a split payment....

Good day, studio2.

You can assign the split transactions by receiving the payment. On the PAYMENT column, enter the amount of payment. Then, you'll have to match not the invoice but the partial payment

To receive:

1. Click the Gear icon, then choose Receive Payment.
2. Select the invoice.
3. Then, on the PAYMENT column, enter the amount.
4. Click Save and close.

To find match:

1. Click the Banking page.
2. Go to the For Review tab.
3. Click the transactions you wish to find match.
4. Click the Find Match button.
5. Then, select the possible transactions that match the payment.
6. Click Save.

The matched transactions will be moved to the In QuickBooks (Excluded) tab.
