# Post-order event types

In the context of eCommerce and business operations, two significant events occur after the completion of an order: the i[nvoice created event](/commerce-api/events/event-types/post-order-event-types/invoice-created-event.md) and the [refund credit memo event](/commerce-api/events/event-types/post-order-event-types/refund-credit-memo-event.md). These events are crucial for financial transactions, customer satisfaction, and record-keeping. The invoice-created event marks the generation of an invoice, indicating a successful order placement and detailing the transaction between the seller and the buyer. On the other hand, the refund credit memo event comes into play when a customer is partially or fully refunded for their purchase. This event ensures that the refund process is documented and that the financial implications are accurately reflected in the company's records. Understanding these events is vital for managing post-order operations efficiently.

See the Post-order notification guide for instructions on how to turn on post-order notifications (PON).
