Configure this task with a customer tag, and Mechanic will take care of applying it to your customers as soon as their order payment goes through. Easy as that. :)
Runs when an order is paid. Configuration includes customer tag.
{% capture tags_to_apply %}{% if order.customer.tags != blank %}{{ order.customer.tags }}, {% endif %}{{ options.customer_tag__required }}{% endcapture %}
