Credit memo and standard Invoice payment

if there are transactions for the same amount and there are credits for the same amounts these should be offsetting each other and consider it paid.

We need to look at this, when Credit memo and standard with exact amount are paid, the system should show that they were paid, but instead they just stay there until more invoice come in. this is not correct! – what happens if we don’t do more business with the company and more invoices do not come in? now we have this two invoices seating in our system as unpaid.

In this scenario we want this to be paid (status to be changed) but we just don’t want a check to be cut… what are our options?
