On my going Project a client requirement was adding custom shipping method so I was trying to solve the problem at last got a solution and it so i liked to share it hope it will be helpful for you.

In this article I will Discuss how to write custom shipping method in Magento commerce. First we need to write our shipping method, it’s a class in folder app/code/core/Mage/Shipping/Model/Carrier/.
I called it Inchoocustom.php and it’s based on Flat rate shipping method but you can developed your own class

< ?php

class Mage_Shipping_Model_Carrier_Inchoocustom
    extends Mage_Shipping_Model_Carrier_Abstract
    implements Mage_Shipping_Model_Carrier_Interface
{

    protected $_code = 'inchoocustom';

    public function collectRates(Mage_Shipping_Model_Rate_Request $request)
    {
        if (!$this->getConfigFlag('active')) {
            return false;
        }

        $freeBoxes = 0;
        if ($request->getAllItems()) {
            foreach ($request->getAllItems() as $item) {
                if ($item->getFreeShipping() && !$item->getProduct()->isVirtual()) {
                    $freeBoxes+=$item->getQty();
                }
            }
        }
        $this->setFreeBoxes($freeBoxes);

        $result = Mage::getModel('shipping/rate_result');
        if ($this->getConfigData('type') == 'O') { // per order
            $shippingPrice = $this->getConfigData('price');
        } elseif ($this->getConfigData('type') == 'I') { // per item
            $shippingPrice = ($request->getPackageQty() * $this->getConfigData('price')) - ($this->getFreeBoxes() * $this->getConfigData('price'));
        } else {
            $shippingPrice = false;
        }

        $shippingPrice = $this->getFinalPriceWithHandlingFee($shippingPrice);

        if ($shippingPrice !== false) {
            $method = Mage::getModel('shipping/rate_result_method');

            $method->setCarrier('inchoocustom');
            $method->setCarrierTitle($this->getConfigData('title'));

            $method->setMethod('inchoocustom');
            $method->setMethodTitle($this->getConfigData('name'));

            if ($request->getFreeShipping() === true || $request->getPackageQty() == $this->getFreeBoxes()) {
                $shippingPrice = '0.00';
            }

            $method->setPrice($shippingPrice);
            $method->setCost($shippingPrice);

            $result->append($method);
        }

        return $result;
    }

    public function getAllowedMethods()
    {
        return array('inchoocustom'=>$this->getConfigData('name'));
    }

}
?>

Pay attention on following lines:

$method->setCarrier('inchoocustom');
$method->setCarrierTitle($this->getConfigData('title'));

$method->setMethod('inchoocustom');
$method->setMethodTitle($this->getConfigData('name'));

They determine how we will set up our method. Keyword is ‘inchoocustom’. In folder app/code/core/Mage/Shipping/etc/ we need to edit
system.xml and config.xml in order to enable our new shipping method.

    </fields>
</inchoocustom>

config.xml:

 

<pre><inchoocustom>
               <active>0</active>
               <sallowspecific>0</sallowspecific>
               <model>shipping/carrier_inchoocustom</model>
               <name>Inchoo Custom Shipping Method</name>
               <price>5.00</price>
               <title>Inchoo Custom Shipping Method</title>
               <type>I</type>
               <specificerrmsg>This shipping method is currently unavailable. If you would like to ship using this shipping method, please contact us.</specificerrmsg>
               <handling_type>F</handling_type>
       </inchoocustom>

Now we need to enable our new shipping method in admin panel (System->Configuration->Shipping Methods) And we have our custom shipping method. Enjoy coding.
