Below you can find all the steps of the order process in Magento.
Magento has four order statuses:
When a customer places an order on your webshop, Magento will register the order in its system. After this is done you will be redirected to the payment service provider (PSP). This process takes only a few milliseconds. Then, Magento then changes the status to "pending". This only means that the order has been created.
Magento can only assign this status if an invoice has been created. Invoices will be created depending on the PSP and payment method. Of course you have the option to create an invoice manually as well.
A customer orders a product at your shop and chooses the payment method: PayPal. After the customer has placed the order, he will be referred to the PSP . The PSP handles the transaction and sends a signal back to Magento. When an order is successfully completed on the side of the PSP, it will send a signal back to Magento so that an invoice can be created automatically. Thereafter, Magento will change its status to "processing".
A customer orders a product at your shop and chooses the payment method: on invoice. The customer will immediately see the success page of Magento. As administrator, you can view the status of the order in the administration section of your shop as "pending". By clicking the "invoice" button, you can manually send the invoice to the customer. Once you have done this, the status of the order will change to "processing”.
The order status will change in "completed" by sending the order to your customer. Magento sees the order as completed when the product /package is sent to the visitor. An order can be sent in Magento by going to the order via the administration section and click the "send" button.
When you cancel an order with a "pending" status it will change in a "canceled" status.
If you want to cancel an order with a "processing" status or "complete" status you will have to create a credit note for this. Cancelling or creating orders can be done via the corresponding buttons which you can find at the top of the order window.
