Shopify Flow is a native automation tool available on standard Shopify plans, not only on Shopify Plus, that allows merchants to create custom automated workflows triggered by events in their Shopify store - without writing code. Workflows are built using a visual editor with three components: a trigger (the event that starts the workflow), conditions (optional rules that determine whether the workflow continues), and actions (what happens when the conditions are met).
One thing to be clear about first: Flow is not a Plus-only feature. It is available on standard Shopify plans, so automating this work does not require an upgrade, and the cost of an upgrade should not be the reason a brand defers it.
What Flow is worth is straightforward. It replaces recurring human attention with a rule, and on a small team attention is the scarcest input. The workflows that pay are the ones with a cost attached to being late: hiding a product the moment stock hits zero so paid clicks stop landing on an unbuyable page, flagging a high-value or high-risk order before it ships, alerting on a hero SKU crossing its reorder point while there is still time to place the purchase order. The discipline is scope. Automate the checks that cost money when missed, leave the rest manual, and review the rules, because every one keeps firing long after the reason for it changed.
The most widely used Flow workflows in e-commerce operations include: automatically tagging orders, customers, or products based on defined criteria (e.g. tag a customer as VIP when they reach a lifetime spend threshold; tag an order as high-risk when it meets multiple fraud signals); sending internal Slack or email notifications when specific events occur (e.g. a product drops below a minimum stock level, a large wholesale order is placed); automatically hiding out-of-stock products from the storefront and republishing them when inventory is restocked; and enrolling customers into specific Klaviyo segments or triggering Klaviyo events based on Shopify behavior (e.g. when a customer's order count reaches 5, trigger a loyalty tier upgrade event in Klaviyo). Flow also integrates with third-party apps through webhooks and direct app integrations, extending its automation capabilities beyond native Shopify actions.
Shopify Flow handles store-side operational automation - inventory management, order tagging, internal notifications, customer segmentation within Shopify. Klaviyo handles customer-facing communication automation - email flows, SMS sequences, and segments based on behavioral data. The two systems are complementary and often work together: Flow can create a customer tag or trigger a Klaviyo metric that then fires a specific Klaviyo email flow. For brands on Shopify Plus, setting up the integration between Flow and Klaviyo creates a unified automation infrastructure that handles both operational and communication workflows from a single set of data signals.
Flow has a ceiling. It's built for straightforward if-this-then-that rules, and workflows that need conditional logic across many variables, higher execution volume, or checkout-level customization tend to hit that ceiling as a brand scales — which is usually the point at which the automation work shifts from stringing together Shopify automation (Flow, Zapier, Arigato) toward the checkout Functions and API-level customization covered under Shopify Plus optimization. Knowing which side of that line a given workflow sits on before building it saves the rebuild later.
Flow's ceiling is easier to judge with a side-by-side view of what the alternatives handle differently — where Zapier and Arigato pick up conditional logic or execution volume that Flow's if-this-then-that model doesn't reach. This comparison of Shopify Flow against other automation tools lays out that trade-off in more detail.
