Shopify Flow: automations without code

The short answer

Flow is Shopify’s built-in automation tool: workflows of the form when this happens, if these conditions hold, do that, triggered by orders, customers, products and inventory, with actions inside the store and in apps that expose them. It needs no code and it is the right tool for store operations housekeeping: flagging risky orders for review, tagging customers by behaviour, alerting on low stock, routing orders, notifying the team about exceptions. It stops at two boundaries. It does not run logic inside the checkout, which is what functions are for. And it does not integrate with arbitrary outside systems or handle complex branching and data transformation, which is where apps and real integrations begin. Like apps, Flow workflows accumulate; document each, give it an owner, and review the list quarterly.

Workflows worth setting up first

Workflow	Trigger and condition	Action
Hold risky orders	Order created and risk level high, or value above a threshold with a new customer	Hold fulfilment; tag; notify
Tag customers by behaviour	First order, repeat order, high lifetime value, returns above a threshold	Add tags for segments used in email and support
Low stock alert	Inventory below a level for a product or collection	Notify the buyer; tag the product
Route orders	Order contains a product needing special handling, or ships to a specific region	Tag; notify the right team
Exception notifications	Order unfulfilled after a number of days; payment failed on a subscription; refund above a threshold	Notify by email or chat
Housekeeping	New product without images or weight; customer without a marketing consent value	Tag for follow-up

Setting it up well

Where it hands over

To functions, when logic must run in the checkout: discounts, shipping options, payment visibility, validation. To integrations and custom apps, when the store must talk to accounting, a warehouse or a CRM in ways beyond what an app’s Flow actions expose, or when the workflow needs branching and data work that Flow cannot express. Flow is the first tool to reach for inside the store and the wrong tool to stretch beyond it.

What this means for you

Use Flow for the store’s operational housekeeping: risk holds, customer tagging, stock alerts, routing and exception notifications, built one job per workflow, tested, documented and reviewed quarterly. Check it before installing simple apps. And when a workflow needs checkout logic or real integration, recognise that it has become software and build it as an app or a function rather than stretching Flow past its edge.
