Final answer:
The document not part of the cash collection process is the packing slip, which is used for shipping purposes rather than recording monetary transactions like the other documents listed.
Step-by-step explanation:
The document that is not part of the cash collection process is D. Packing slip. The cash collection process generally involves documents that record monetary transactions. A remittance advice is a notice of payment sent to a business by a customer and often accompanies a cheque or other forms of payment, a cash receipts journal is a ledger book in which all cash transactions are recorded, and a bank deposit slip is used to deposit funds into a bank account. However, a packing slip is used to inform transport agencies and customers about the contents of a package; it is not directly related to cash transactions and therefore is not a part of the cash collection process.
