Unapplied cash payment is income received (on cash basis) but not connected to any invoice. So, for example, if you record a $1,000 payment received in QB on Mar. 1, but the invoice for that payment is dated later, say Mar. 15, then from Mar. 1 to Mar. 14 you will have $1,000 in unapplied cash payment income. If these payments received don't match your bank statement then, presumably, they are dated incorrectly, were recorded incorrectly, or the deposits were made at a later date. If you have payments received, there should be a corresponding bank deposit.
