Change single element of a paid invoice (product/service) without deleting rest of the row

When you change an item, it will delete the information in the whole row, MaxlineJenn.

You're on the right path. You'll have to re-enter the details. Although, if the prices are the same, it will not create a balance due. The payment may be unlinked. This will create an Unapplied payment. Let's go ahead and link it. 

Here's how:

1. Open the invoice.
2. Click Receive payment.
3. Under Credits, select the Unapplied Payment.
4. Ensure the payment date is correct.
5. Click Save and close. 

The customer should now have a zero overdue balance.
