I've had a business for many years now and was previously creating invoices on a separate platform before making the switch to Quickbooks. Because of this, one of the checks deposited is creating an open balance  for one of my clients because the invoice is not in Quickbooks, its from one of the invoices prior to the switch. Creating a Journal Entry didn't work because I have a check deposited that I cannot match to anything that is causing the issue. Should I just delete the deposit? I don't want it to mess anything up. I'm not an accountant, so I have no idea how to proceed.
