i want to change customer group on one-page checkout based on checkout address .

Basically two type of customer group : Indian Customer , Outside India, if checkout country is other than India customer groups should auto switch to Outside India

issue : can same be applied for guest customer (non logged in users also).

I am using tier price for products based on Customer Group.

Please help me with way to do same .

  • I think you should change your customer flow. Because run time it might be difficult to change the customer group and apply the correct tier price.

Use event :- here is event : etc/frontend/events.xml "checkout_onepage_controller_success_action"

public function execute(\Magento\Framework\Event\Observer $observer ) {        

//Get order details
$order = $observer->getEvent()->getOrder(); <br>
$guestCustomer = $order->getCustomerIsGuest(); <br>
$groupId  = $order->getCustomerGroupId(); <br>

Check for the country id and then inject customer class

private $customerRepository;

public function __construct(
    \Magento\Framework\App\RequestInterface $request,
     CustomerRepositoryInterface $customerRepository
    $this->_request = $request;
    $this->customerRepository = $customerRepository;


    $id = $observer->getEvent()->getCustomer()->getId();
    $customer = $this->customerRepository->getById($customerid);

//Set customer to the group id as per requirement $customer->setGroupId($group_id);

Change code as per requirement , basically this is the logic.

  • can customer group be set for guest user Commented Apr 12, 2020 at 12:03
