Invoices are marked paid for bank transfer payment automatically

Question

I have stackoverflowed, googled etc but couldn't find the answer. I want to understand the logic behind the bank transfer payment method and invoice.

When we create invoices for orders that have payment method as Bank Transfer, invoice goes to PAID status by default.

Problem

In most cases, customer has yet not made full payment but have to send them invoice to ask for payment, which is why it must not marked as PAID in my case.

The function $this->canCapture() returning false for bank transfer orders.

Question

I would like to know how invoices are handled for bank transfer payment and is there a way to create invoice without marking it as PAID?

Answer 1

The status on the invoice is set in the method Mage_Sales_Model_Order_Invoice::pay() :

$invoiceState = self::STATE_PAID;
if ($this->getOrder()->getPayment()->hasForcedState()) {
   $invoiceState = $this->getOrder()->getPayment()->getForcedState();
}

So by default is set to paid if there is no "forced state" on the payment method.

you can use the event sales_order_invoice_pay dispatched in the same method to check if payment was done via bank transfer and set a different state to your invoice.
