Hi. There. I am a newbie on express accounting. Straight to the question. I have two invoices created for example A invoice with $50 and B with $25 . A client paid $75 .You then go to the payment option and selected A & B invoices to be applied; the result come undesirable instead of showing A& B That are applied it then pools out a long receipt of other invoices not selected. How can we resolve the issue.
