Does anyone know how to match 2 payments to one invoice in a foreign currency?

Hello there, Joseph. I'll share details about recording a customer's payments for a single invoice in QuickBooks Online (QBO).

Matching multiple payments directly to a single invoice from the Banking page in QBO isn't available. You'll have to manually Receive Payment and deposit payments into the undeposited funds account so you can combine them into a single deposit.

To start, you'll have to record the separate payments by manually creating partial payments for an invoice. Here's how:

1. Go to the + New, then click Receive payment.
2. Select the name of the customer from the Customer dropdown.
3. Make sure to select the correct currency exchange rate
4. From the Payment method dropdown, choose the payment method.
5. From the Deposit to dropdown, select the Undeposited Funds account to group the payment with others.
6. Enter the amount your customer paid in the Amount received field.
7. In the Outstanding Transactions section, select the checkbox for the invoice you're recording the payment.
8. Once done, tap Save and close.
   
   

 After that, if your client's second payment makes the invoice totally paid, then you can generate a bank deposit to combine the payments. Otherwise, you'll have to wait until the invoice is paid before recording a bank deposit.

Furthermore, you can simply exclude payment transactions that showed up in your bank feeds to avoid getting duplicate income. Here's an article for reference: Exclude a bank transaction you downloaded into QuickBooks Online.

Please reply to this post if you have further questions about recording payment transactions with different currencies. I'll be happy to lend a hand. Have a good one!
