We now do various projects for Shopify store owners. Some of our recent Shopify projects included such tasks:

• tag orders with the chosen payment method and cart attributes (when a user selects pickup location before going to the checkout);
• tag orders that are to be delivered to certain zip codes (think offshore shipping destinations in the UK);
• tag customers that bought VIP pass to the exclusive product collection so they could access it (see my post here);
• remove customer tags based on purchase behavior;
• retrospectively (for all orders in the store) add customer tags based on purchasing history (total spent, brands bought, etc.);
• bulk create products from vendor inventory files;
• sync orders and inventory with Brightpearl ERP.

We can configure the automation flow to tag orders and/or customers based on almost any defined conditions. Think IFTTT for Shopify. But much more powerful.
Investment in automation like one of these will definitely benefit your business.
