If you’re building an ecommerce store and want to leverage WhatsApp marketing, your choice of platform matters more than you think.
Shopify and Medusa are both excellent platforms, but they have very different approaches to WhatsApp integration. Here’s what you need to know.
TL;DR: The Quick Answer
Choose Shopify if:
- You want plug-and-play simplicity
- You’re okay with higher monthly costs (€29-289/month)
- You value the massive app ecosystem
- You don’t need custom checkout experiences
Choose Medusa if:
- You want full control and customization
- You’re comfortable with code (or have a developer)
- You want lower long-term costs (self-hosted = free)
- You need multi-region, multi-currency by default
For WhatsApp marketing specifically: Both platforms work great, but the integration approach differs significantly.
Let’s break it down.

WhatsApp Integration: How They Compare
Shopify + WhatsApp
Integration method: Shopify app or webhook-based integration
How it works:
- Install a WhatsApp app from Shopify App Store (or use Nudge)
- Connect your WhatsApp Business API account
- Configure automation rules in the app dashboard
- App receives Shopify webhooks (cart updates, orders, etc.)
- App sends WhatsApp messages via WhatsApp Business API
Setup time: 5-10 minutes with the right app
Pros:
- Very easy setup (click, click, done)
- No code required
- Works immediately with your existing Shopify store
- App handles all the complexity
Cons:
- Monthly app fees (typically €29-99/month for WhatsApp apps)
- Limited to what the app offers (can’t customize deeply)
- Depends on app developer maintaining compatibility
Best WhatsApp use cases on Shopify:
- Cart abandonment recovery
- Order confirmations and shipping updates
- Replenishment reminders
- Post-purchase upsells
- Customer support
Example integration flow:
Customer abandons cart
↓
Shopify triggers "Cart Updated" webhook
↓
WhatsApp app receives webhook
↓
App sends WhatsApp message via API
↓
Customer receives message on WhatsApp
Medusa + WhatsApp
Integration method: Custom plugin or direct API integration
How it works:
- Install Medusa WhatsApp plugin (like Nudge’s Medusa plugin)
- Connect your WhatsApp Business API credentials
- Plugin listens to Medusa events (order.placed, cart.updated, etc.)
- Plugin sends WhatsApp messages via WhatsApp Business API
Setup time: 10-15 minutes (one-line npm install + config)
Pros:
- Deeper integration (access to full event system)
- More customization options
- Can modify plugin source code if needed
- Typically lower cost (plugins are cheaper than SaaS apps)
- Better performance (runs in same process as Medusa)
Cons:
- Requires basic Node.js knowledge
- Fewer “click-and-go” solutions (for now)
- You’re responsible for hosting the plugin
Best WhatsApp use cases on Medusa:
- Everything Shopify can do, plus:
- Multi-region messaging (different languages per region)
- Custom campaign logic based on customer segments
- Advanced product recommendation engines
- Hybrid cart recovery (email + WhatsApp)
Example integration flow:
Customer abandons cart
↓
Medusa emits "cart.updated" event
↓
WhatsApp plugin subscriber listens for event
↓
Plugin sends WhatsApp message via API
↓
Customer receives message on WhatsApp
Real-World Scenarios
Scenario 1: Small Fashion Boutique (Non-Technical Owner)
Requirements:
- Quick setup
- No technical team
- Cart abandonment + order updates via WhatsApp
- €5,000-10,000/month revenue
Recommendation: Shopify
Why:
- Setup in 1 hour (vs 1 week learning Medusa)
- No developer needed
- Plenty of WhatsApp apps to choose from
- Total cost: ~€58/month (Shopify Basic + WhatsApp app)

Scenario 2: Coffee Subscription Service (Technical Founder)
Requirements:
- Multi-country shipping (Europe)

Scenario 3: B2B Wholesale Business
Requirements:
- Custom pricing per customer
- Bulk ordering
- WhatsApp order notifications to sales team
- Integration with existing ERP
Recommendation: Medusa
Why:
- Headless architecture makes ERP integration easier

Cost Breakdown: 12-Month Comparison
Let’s compare the true cost of running WhatsApp marketing on both platforms.
Assumptions:
- €30,000/month revenue
- 1,000 orders/month
- 2,000 WhatsApp messages/month
Shopify Total Cost (12 months)
- Shopify subscription: €79/month × 12 = €948
- WhatsApp app: €59/month × 12 = €708
- Transaction fees (2%): €600/month × 12 = €7,200
- WhatsApp API costs: €160/month × 12 = €1,920
Total: €10,776 per year
Medusa Total Cost (12 months)
- Medusa Cloud: €20/month × 12 = €240 (or €0 if self-hosted)
- WhatsApp plugin: €59/month × 12 = €708
- Transaction fees: €0
- Hosting (if self-hosted): ~€50/month × 12 = €600
- WhatsApp API costs: €160/month × 12 = €1,920
Total: €3,468 per year (€1,548 if self-hosted)
Savings with Medusa: €7,308/year (€9,228 if self-hosted)
That’s enough to hire a part-time developer to customize your Medusa store.
Developer Experience: Building Custom WhatsApp Flows
Shopify: App-Dependent
If you want custom WhatsApp logic on Shopify, you’re limited to:
- Whatever the app offers (usually basic automation)
- Building a custom Shopify app (requires learning Shopify API)
- Using webhooks + external service (adds complexity)
Example: Custom logic for “send WhatsApp only to high-value customers”
- With app: Hope the app supports customer segmentation
- Custom: Build a webhook handler, filter customers, call WhatsApp API
Medusa: Full Control
Medusa’s event-driven architecture makes custom logic straightforward.
Example: Same “high-value customer” logic
// Medusa subscriber (simplified)
class WhatsAppSubscriber {
constructor({ whatsappService, orderService }) {
orderService.on('order.placed', async (order) => {
// Custom logic: only message if order > €100
if (order.total > 10000) {
await whatsappService.sendMessage({
to: order.customer.phone,
template: 'high_value_order_confirmation',
params: {
name: order.customer.first_name,
total: formatCurrency(order.total),
},
});
}
});
}
}
That’s it. You have full control over when and how WhatsApp messages are sent.
Migration Considerations
Moving FROM Shopify TO Medusa
Reasons to migrate:
- Save on monthly fees (especially at scale)
- Need more customization
- Want to own your infrastructure
- Need multi-region/multi-currency
WhatsApp impact:
- Re-setup WhatsApp integration (plugins work similarly to apps)
- Re-approve message templates with Meta (same process)
- Migrate customer opt-in data
Migration difficulty: Medium (use Medusa’s import tools)
Moving FROM Medusa TO Shopify
Reasons to migrate:
- Want less technical overhead
- Need specific Shopify apps
- Prioritize ease-of-use over customization
WhatsApp impact:
- Re-setup WhatsApp integration (apps work similarly to plugins)
- Same message templates (already approved with Meta)
- Import customer opt-in data
Migration difficulty: Medium (Shopify has import tools)
Which Should You Choose?
Choose Shopify if:
- You’re non-technical or have no dev team
- You value speed and convenience over cost
- You want a proven, battle-tested platform
- You’re okay with monthly SaaS fees
- You don’t need deep customization
Best for: Small to medium stores, non-technical founders, stores needing quick setup
Choose Medusa if:
- You’re technical or have a developer
- You want to save on long-term costs
- You need multi-region/multi-currency out of the box
- You want full control over your codebase
- You’re building something custom or complex
Best for: Technical founders, agencies, multi-region brands, B2B businesses
For WhatsApp Marketing Specifically:
Both platforms work great. The choice comes down to:
- Shopify: Easier setup, higher cost, less flexibility
- Medusa: More setup, lower cost, more flexibility
If you’re just starting with WhatsApp marketing: start with Shopify (faster). You can always migrate to Medusa later if you outgrow it.
If you’re technical and care about costs: start with Medusa. You’ll save thousands per year and have more control.
The Bottom Line
There’s no “wrong” choice between Shopify and Medusa for WhatsApp marketing—both work.
Shopify is the Toyota Camry of ecommerce: reliable, easy, proven, but you pay for convenience.
Medusa is the custom-built sports car: powerful, efficient, exciting, but requires a driver who knows what they’re doing.
For WhatsApp marketing, the integration approach is different, but the results are the same: higher open rates, better customer engagement, and more revenue.
Pick the platform that matches your technical ability and budget. Then focus on actually implementing WhatsApp marketing—that’s where the real ROI is.
