Although Cash Receipts Entry is designed primarily for posting cash or credit card payments to reduce customer balances or pay open invoices, you may occasionally need to prepay an invoice that is not yet in the system, use a cash or credit card payment received to reduce a debit memo, apply a credit memo to an invoice or outstanding balance, credit a finance charge issued to a customer, or make a miscellaneous adjustment to a general ledger account.
Miscellaneous cash receipts can be applied directly to general ledger accounts and posted to the bank. Miscellaneous credit card receipts can also be applied directly to general ledger accounts. You can enter miscellaneous cash receipts using any one of the following procedures:

Prepay an Invoice
Apply a Cash or Credit Card Receipt to a Debit Memo
Apply a Credit Memo to an Invoice
Credit a Finance Charge
Write Off a Bad Debt
