My invoice total is going up $125 (a travel fee needed to be added). The client already paid a 50% deposit via Square, so there's half remaining. When I edit the invoice to add the $125, it says the deposit still needs to be paid by $62.50 (50% of that). I don't need her to pay that, I just want to add $125 to her REMAINING invoice amount. I only want her to pay one more time, and not have to redo her first payment, so I'm not inconveniencing her. Is there a way to only just the balance remaining on an invoice that already collected a deposit?

for ease: Let's say the invoice was $1,000 and she already paid $500, I want the invoice to now read that she owes $625.

Thank you!
