The default behavior for Drupal Commerce is that an anonymous user get's registered only after the checkout process completes and an order is paid in full. I am trying to create a new checkout rule to register an user just after he/she enters his/her e-mail address, but failing to find the right rule on admin/config/workflow/rules/reaction/manage/rules_sd/add/event.
I have modified my checkout flow, so that a user can enter his/her e-mail at the first step like shown in the screenshot:
Unfortunately, there is no rule something like "After entering an e-mail". Does anyone have a suggestion how to overcome this problem?
On /admin/commerce/config/checkout/rules it says:
When a customer advances to the checkout completion page, rules reacting on the Completing the checkout process are evaluated. Default rules handle standard tasks like updating the order status, sending order e-mails, and creating accounts for anonymous users. You can edit these or add additional rules to customize your checkout workflow.
Does this mean I can't trigger any actions until checkout completes? Not very much convenient if so.
Edit: I've also found this somewhat similar discussion: How to force account creation before commerce checkout is complete?
