Final answer:
The correct sequence in an online sales process is that the customer places an order before making a payment. This ensures product availability and order confirmation before financial commitment. The discussed sequence is customer-centric and typical in e-commerce transactions.
Step-by-step explanation:
In the sales process, when discussing the sequence of events in an online transaction, certain steps occur in a specific order. One of the key sequences involves the customer placing an order before making a payment.
Therefore, the correct sequence from the options provided is Customer order, then Customer payment.
This order ensures that the vendor confirms the details and availability of the product before the customer commits their money. It's a basic principle in the flow of e-commerce transactions, where establishing the order precedes the request or confirmation of payment.
When we look at the invoice and payment process, typically, after the customer places their order and the order is processed and shipped, they receive a shipping notice.
Subsequently, the customer's payment is confirmed, and the transaction is completed. A vendor order or a work-in-process would not precede the customer-focused steps in the sales process.
