Why Shopify Flow Is the Most Underused Shopify Feature
Shopify Flow is Shopify’s native automation builder — available on all Shopify plans — that allows store owners to create automated workflows triggered by store events without writing code. Despite being included in every Shopify plan, most store owners either haven’t discovered Flow or haven’t invested the time to configure automations that would eliminate hours of weekly manual work. The potential is significant: automatically tag high-value customers when they cross a lifetime value threshold, hide out-of-stock products from collections when inventory hits zero, send internal Slack alerts when a high-value order needs review, apply risk scores to fraud-suspicious orders, and send automated email drafts when customers need follow-up. Shopify Flow handles these repetitive, rule-based operations continuously in the background so your team can focus on work that actually requires human judgment.
This guide covers how to use Shopify Flow effectively — from understanding triggers, conditions, and actions to building the specific automation workflows that eliminate the most common manual store management tasks.
Step 1: Understand Shopify Flow’s Structure
Every Flow automation has three components:
- Trigger — the event that starts the workflow. Shopify Flow triggers include: Order created, Order fulfilled, Order paid, Order cancelled, Customer created, Customer updated, Product created, Product updated, Inventory quantity updated, and more. The trigger is what “fires” the workflow — when this happens, the rest of the flow executes.
- Condition — optional filters that check whether specific criteria are met before executing actions. If Order created is your trigger, conditions might check: “Is the order total greater than $500?” or “Does the customer have more than 3 previous orders?” Conditions allow a single trigger to branch into different actions based on order, customer, or product attributes.
- Action — what the workflow does when the trigger fires and conditions are met. Actions include: Add tag (to order, customer, or product), Remove tag, Send email, Send HTTP request (to external services), Add a timeline comment, Hide/show product, Adjust inventory, and more on Shopify Plus (cancel order, pause fulfillment).
Shopify Flow workflows are built in a visual editor — no code required. Access it from Shopify admin → Apps → Flow, or install the Flow app from the Shopify App Store if it isn’t already installed on your store.
Step 2: Build Customer Segmentation Automations
Shopify Flow’s most impactful applications automatically tag customers based on purchase behavior, enabling email platforms and loyalty apps to act on those tags:
- VIP customer tagging — create a Flow that triggers on Order paid, checks if the customer’s total spent exceeds your VIP threshold (e.g., $500 lifetime spend), and adds a “VIP” tag to the customer. Your email platform (Klaviyo) can then automatically trigger a VIP welcome email when this tag appears. Update: rebuild this as a recurring check with the “Customer updated” trigger to catch customers who cross the threshold on any order, not just their first.
- New customer tagging — trigger on Order paid, check if order count equals 1 (first purchase), and add “new-customer” tag. Klaviyo reads this tag to trigger your new customer onboarding sequence immediately rather than relying on email platform timing alone.
- At-risk customer tagging — this requires Shopify Flow’s scheduled automation (Flow can run on time-based triggers): daily check customers whose last order date was 90+ days ago and add “at-risk” tag, triggering your win-back email flow in Klaviyo. Remove the tag if the customer places a new order.
- Repeat buyer tagging — when a customer places their second order (order count = 2), tag them “repeat-buyer” to trigger your returning customer email sequence and update their loyalty tier in your loyalty app.
Step 3: Automate Inventory Management
Inventory management automation prevents the customer experience problems caused by out-of-stock products appearing in your store:
- Auto-hide out-of-stock products — create a Flow that triggers on Inventory quantity updated, checks if all inventory across all locations is 0, and adds a “hidden” tag to the product (if your theme uses tags for collection visibility) or sets the product status to Draft. This removes products from customer-facing collections automatically when stock runs out, preventing orders you can’t fulfill.
- Auto-restore in-stock products — trigger on Inventory quantity updated, check if inventory has returned to above 0 (restock event), and remove the “hidden” tag or set product status to Active. Combine with an internal Slack or email notification so your marketing team knows to promote newly restocked products.
- Low inventory alerts — trigger on Inventory quantity updated, check if inventory falls below your reorder threshold (e.g., 10 units), and send an internal email notification or Slack alert to your inventory manager. Proactive low inventory alerts prevent stockouts caused by delayed reorder decisions.
- Out-of-stock collection management — add a tag to products when they go out of stock that your collection rules filter out: create a Smart Collection with “Tag is not equal to out-of-stock” rule so collections automatically exclude unavailable products.
Step 4: Create Order Management Workflows
Order management automations handle the post-purchase processing that previously required manual review:
- High-value order review flags — trigger on Order created, check if order total exceeds your high-value threshold (e.g., $300), and add an “high-value” tag plus send an internal Slack notification for manual order review. High-value orders that also trigger fraud risk signals (different billing/shipping addresses, multiple quantities of a single item) deserve human review before fulfillment.
- Fraud risk flagging — trigger on Order created, check if the order risk level is “High” (Shopify’s built-in fraud risk assessment), and add a “needs-review” tag plus hold fulfillment (on Shopify Plus). Low-risk orders proceed automatically; high-risk orders pause for human review before shipping.
- Gift order detection — trigger on Order created, check if the order has a gift note or different billing/shipping name, and add a “gift-order” tag. Your fulfillment team can then apply gift packaging procedures without manually checking each order for gift notes.
- International order flagging — trigger on Order created, check if shipping country is outside your primary market (e.g., not United States), and add an “international” tag plus send an internal notification. International orders may require different customs documentation or carrier selection — flagging them automatically ensures your fulfillment team applies the right process.
Step 5: Build Product Management Automations
Product management automations maintain your catalog without manual oversight:
- New product auto-tagging — trigger on Product created, check creation date (within the last 30 days), and add a “new-arrival” tag. Your collection rules can show a “New Arrivals” collection that automatically populates with recently added products without manual collection management.
- Sale product management — when you add a “sale” tag to products (via bulk edit for a sale event), a Flow can automatically move the product to your Sale collection, add a “SALE” badge metafield, and remove these automatically when the “sale” tag is removed at the end of the sale period.
- Vendor product organization — trigger on Product created, check the vendor field, and automatically add collection tags based on vendor. Products from Vendor A automatically go to Collection A without manual collection assignment.
Step 6: Connect Flow to External Services
Shopify Flow’s HTTP Request action enables integration with any external service that accepts webhook data:
- Slack notifications — use the Send HTTP request action to post to a Slack webhook URL when specific events occur: new high-value orders, first purchase from a customer, out-of-stock product alerts, or negative review flags (from Yotpo webhook → Flow → Slack). Real-time Slack alerts give your team immediate visibility into store events that need attention.
- Klaviyo event triggering — send customer events directly to Klaviyo’s track API via HTTP request when Flow conditions are met: customer crossed VIP threshold (trigger Klaviyo VIP welcome flow), customer tagged at-risk (trigger Klaviyo win-back flow), customer’s birthday this week (trigger Klaviyo birthday campaign).
- Google Sheets logging — log specific events to a Google Sheet via the Sheets API for reporting purposes: high-value orders for accounting review, fraud-flagged orders for risk analysis, new VIP customers for relationship management.
Step 7: Use Flow Templates to Start Quickly
Shopify Flow includes pre-built templates for common use cases — a faster starting point than building from scratch:
- Accessing templates — in Shopify admin → Apps → Flow → Templates, browse available workflow templates. Categories include: Customer management, Order management, Inventory management, and Product management. Install any template with one click and then customize the conditions and thresholds for your specific store.
- Most useful templates — “Tag high-spending customers as VIP,” “Hide out-of-stock products,” “Send internal email for high-risk orders,” “Tag customers by number of orders,” and “Send internal notification for large orders” are the highest-impact templates for most stores. Install all five and customize the threshold values before moving to custom workflow building.
- Template customization — every template requires threshold customization: the VIP spending threshold appropriate for your store is different from the default; your high-risk order value is different from the template default. Review every template’s conditions against your actual store data before enabling.
Frequently Asked Questions
What is Shopify Flow and is it free?
Shopify Flow availability and cost: Shopify Flow is Shopify’s native automation app, available at no additional cost on all Shopify plans (Basic, Shopify, Advanced, and Plus). Previously Flow was available only on Shopify Plus; Shopify expanded Flow access to all plans in 2022. To access Flow: in your Shopify admin, go to Apps → search for “Flow” → install the Shopify Flow app. If it’s already installed, it appears in your Apps list. Flow is built natively into Shopify’s infrastructure, meaning automations run reliably without performance impact from third-party apps. The limitations between plans: Shopify Basic, Shopify, and Advanced support the majority of Flow actions; Shopify Plus adds additional actions like Cancel Order, Pause Fulfillment, and access to B2B automation triggers. For most stores on standard Shopify plans, the available actions cover all common automation needs without requiring Plus upgrade specifically for Flow.
What can Shopify Flow automate that apps can’t?
Shopify Flow vs. third-party automation apps: Shopify Flow has native access to all Shopify data objects (orders, customers, products, inventory, fulfillment) without API rate limit overhead — it runs on Shopify’s internal infrastructure. This gives Flow advantages for automation that touches core Shopify data: customer tagging based on purchase history, product status changes based on inventory, order tagging based on risk signals, and internal notifications based on order events. Third-party automation apps (Zapier, Make/Integromat) are better for: multi-app orchestration (connecting Shopify to non-Shopify apps like HubSpot CRM, QuickBooks, or Airtable), complex conditional logic that exceeds Flow’s visual builder capabilities, and workflows that require data transformation between systems. The optimal setup for most stores: Shopify Flow handles all automations that only touch Shopify data; Zapier or Make handles workflows that connect Shopify to external systems. Avoid duplicating functionality between platforms — it creates maintenance overhead and potential conflicts when both platforms respond to the same event.
How do I use Shopify Flow to tag customers automatically?
Automatic customer tagging with Shopify Flow: in Flow, create a new workflow. Set the Trigger to “Order paid.” Add a Condition checking “Customer total spent is greater than [your threshold].” Set the Action to “Add tag to customer” with your tag name (e.g., “vip”). Enable the workflow. Now whenever an order completes and the customer’s lifetime spend crosses your threshold, the VIP tag is automatically applied. For more sophisticated segmentation, add multiple condition branches: if spend greater than $1,000 → tag “vip-gold”; if spend greater than $500 → tag “vip-silver”; if order count = 1 → tag “first-time-buyer”. Your email platform (Klaviyo) reads these tags via Shopify integration and can trigger flows, change segment membership, and update loyalty tier assignments automatically. Key note: Flow conditions evaluate customer data at the moment the trigger fires, so a customer who crosses the VIP threshold on their 5th order gets tagged on that 5th order, not retroactively on earlier orders. Run a one-time Klaviyo segment for existing customers who should have VIP tags and add them manually for historical accuracy.
Can Shopify Flow send emails automatically?
Email sending via Shopify Flow: Shopify Flow can send emails in two ways. First, via the Send internal email action — this sends emails to specific email addresses (your team members) with order data, customer data, or custom messages. This is for internal notifications, not customer-facing emails. Second, via the HTTP Request action — send a request to your email platform’s API (Klaviyo’s track events API, Mailchimp’s transactional email API, etc.) which triggers a customer-facing email campaign or flow. For customer emails, the best practice is to use Flow to fire events into Klaviyo (via Klaviyo’s API) and let Klaviyo handle email rendering, personalization, and delivery — Klaviyo’s email builder is far more capable than anything Flow can directly generate. The combination: Flow fires the trigger → Klaviyo receives the event → Klaviyo sends the personalized, branded email. This separation of concerns (Flow for logic, Klaviyo for email) produces better results than trying to send customer emails directly from Flow.
What are the best Shopify Flow automations for a growing store?
Highest-impact Shopify Flow automations by store size: for stores doing $0-$50K/month, the three most valuable automations are: (1) VIP customer tagging (automatically tag your top 10-15% of customers by spend so your email platform can market to them differently); (2) Out-of-stock product hiding (prevent purchases of products you can’t fulfill); (3) High-risk order flagging (prevent chargebacks by catching fraud-risk orders before fulfillment). For stores doing $50K-$250K/month, add: (4) First purchase vs. repeat purchase tagging (segment new vs. returning buyers for different email flows); (5) Low inventory internal alerts (give your buying team lead time before stockouts); (6) International order routing notifications (ensure your fulfillment team applies correct customs documentation). For stores above $250K/month on Shopify Plus, add: (7) Automated fulfillment hold for fraud-risk orders; (8) B2B customer tagging and wholesale price tier assignment; (9) Inventory rebalancing across locations via third-party WMS integration. Start with the three foundational automations and add incrementally as operational complexity grows — the goal is eliminating manual work, not building automation for its own sake.
Final Thoughts
Shopify Flow is one of the most valuable tools available to Shopify store owners that most stores significantly underutilize — it’s free, native to Shopify, and capable of eliminating hours of manual work weekly once properly configured. Start with the template workflows that match your most frequent manual tasks, customize the thresholds for your store’s specific economics, and build incrementally toward the automation library that runs your store operations continuously in the background. The stores that invest in Flow configuration create operational leverage — their team handles the same order volume with less manual oversight, their customer segmentation stays current automatically, and their inventory management prevents the customer service issues that out-of-stock orders generate. Automation done right makes your store more reliable and more professional simultaneously.
