Every dollar lost to fraud on Shopify actually costs you $4.61 when you add up chargebacks, processing fees, lost inventory, and the hours you spend filing disputes. That number comes from Shopify's own fraud cost analysis. The best Shopify fraud prevention apps catch these losses before they happen — by screening orders, verifying buyers, and blocking bots before they reach your checkout.

Global ecommerce fraud hit $48 billion in 2025, according to Juniper Research. Chargeback volume is projected to reach 337 million disputes in 2026. And if your chargeback rate crosses Shopify's unofficial 1% threshold, you risk getting flagged by payment processors — or worse, losing your Shopify Payments account entirely. Whether you're dealing with stolen credit cards, fake COD orders, or bot attacks, you need protection that matches your specific threat.

This roundup covers 8 Shopify fraud prevention apps across three categories: chargeback protection for prepaid orders, COD-specific fraud tools, and bot/IP blocking. Each one is verified on the Shopify App Store with real pricing and ratings.

Best Shopify Fraud Prevention Apps for Chargeback Protection

If you accept credit cards, chargebacks are your biggest fraud risk. These apps review orders before you ship, flag suspicious ones, and in some cases guarantee reimbursement if a fraudulent order slips through.

1. Signifyd

Signifyd is the enterprise-grade option. Its AI analyzes every order in real time and gives an instant approve or decline decision. The key selling point: a financial guarantee. If Signifyd approves an order that turns out to be fraudulent, they cover the chargeback. That guarantee is why large Shopify Plus stores use it — you're transferring fraud risk to Signifyd instead of absorbing it yourself.

Pricing: 1% of total order amount on the small business plan. Mid-market plan starts at $1,000/month.
Best for: Stores processing high order volumes where chargeback guarantees justify the cost.

2. Chargeflow

Chargeflow takes a different approach. Instead of preventing chargebacks upfront, it automates the dispute process after they happen. Its AI builds evidence packages using millions of data points and submits them on your behalf. You only pay when Chargeflow wins a dispute for you.

Rating: 4.7/5 stars (376 reviews)
Pricing: Free to install. 25% fee on successfully recovered chargebacks. $39 per chargeback prevented through alerts.
Best for: Stores that want hands-off chargeback management without upfront costs.

3. NoFraud (Wyllo)

NoFraud — recently rebranded to Wyllo on the Shopify App Store — screens every order and delivers a clear pass or fail decision. It combines AI analysis with human review for edge cases, which tends to reduce false declines (legitimate orders incorrectly flagged as fraud). Over 7,000 brands use it, and it includes chargeback protection on approved orders.

Pricing: Transaction fees starting at 0.45% of order value.
Best for: Mid-size stores that want both automation and human review without enterprise pricing.

COD Fraud Prevention Apps

Cash-on-delivery fraud looks different from credit card fraud. There are no chargebacks — instead, you're dealing with fake orders, duplicate orders from the same phone number, and customers who refuse delivery. The cost is shipping fees, wasted inventory handling, and courier return charges. These apps verify buyer intent before you ship. (For a deeper look at the full cost breakdown, see our guide on the true cost of COD fraud.)

4. EasySell COD Form & Upsells

EasySell isn't a standalone fraud app — it's a COD order form with fraud prevention built in. That's actually an advantage for COD merchants because verification happens inside the ordering flow, not as a separate layer. Customers verify their phone number via OTP (SMS or WhatsApp) before the order goes through. You can also block specific phone numbers, email addresses, and IP addresses, set order quantity limits, and restrict COD by postal code.

The partial payment feature doubles as fraud prevention: requiring even a small deposit filters out buyers who aren't serious. Stores using deposit collection alongside OTP verification typically see the sharpest drop in return-to-origin rates.

Pricing: Free plan available. Paid plans from $9.95/month.
Best for: COD merchants who want fraud prevention, order forms, and upsells in one app instead of stacking three separate tools.

5. COD King

COD King focuses specifically on order verification and partial payments for COD stores. It sends OTP verification via SMS or WhatsApp and lets you collect deposits to confirm buyer intent. The app is straightforward — it does COD verification and does it well, without the upsell and form customization features that broader apps include.

Pricing: Free plan available. Paid plans from $9.99/month.
Best for: COD stores that only need verification and deposits without additional order form features.

Bot and IP Blocking Apps

Not all fraud comes from humans. Bots scrape your pricing, inflate your traffic analytics with junk visits, and sometimes place automated fake orders. These apps block suspicious traffic before it reaches your checkout.

6. Blocky Fraud Filter IP Blocker

Blocky lets you block visitors by email, phone number, IP address, or country. Its AI-based bot detection catches automated traffic that bypasses standard CAPTCHA. Merchants frequently praise it for cleaning up their analytics — once you filter out bot traffic, your conversion rate data actually means something.

Rating: 4.6/5 stars (265 reviews)
Pricing: Free for development stores. $4.99/month (Basic), $7.99/month (Advanced), $12.99/month (Pro).
Best for: Stores dealing with bot traffic, competitor scraping, or region-specific fraud patterns.

7. Blockify Fraud Filter

Blockify covers similar ground as Blocky — IP blocking, country blocking, bot detection — but adds VPN and proxy detection as a key differentiator. If you're seeing fraud from customers hiding behind VPNs, Blockify catches that. It also includes redirect rules, so instead of showing a blank page to blocked visitors, you can send them to a custom page.

Pricing: Free plan available. Paid plans from $5.99/month.
Best for: Stores that need VPN/proxy detection alongside standard IP and country blocking.

8. Beacon Fraud Prevention

Beacon sits between the budget blockers and the enterprise solutions. It analyzes orders in real time, checking risk signals like mismatched billing and shipping addresses, VOIP phone numbers, and failed CVV checks. What makes Beacon different is customization — you can adjust the detection rules based on your store's specific fraud patterns instead of relying on one-size-fits-all algorithms.

Rating: 4.9/5 stars on Shopify App Store
Pricing: Plans start at $29/month with a free trial.
Best for: Small to mid-size stores that want order-level fraud scoring with adjustable rules.

Which Fraud Prevention App Is Right for Your Store?

The right fraud prevention app depends on what kind of fraud you're actually experiencing. Here's a quick decision framework by threat type:

Chargebacks on prepaid orders: Start with Chargeflow (no upfront cost) or Beacon (affordable order screening). Move to Signifyd or NoFraud when your volume justifies the per-transaction fee.

Fake COD orders and high RTO: You need OTP verification and partial payments. EasySell combines these with order form features. COD King covers verification if that's all you need.

Bot traffic and scraping: Blocky or Blockify at $5-13/month. Quick setup, immediate impact on analytics accuracy.

Multiple fraud types: Stack one app from each category. A COD verification app and an IP blocker don't conflict — they protect different parts of your funnel.

One thing to watch: don't over-block legitimate customers. Every fraud rule you add is a potential friction point. Start with the minimum protection that addresses your actual losses, monitor the results for two weeks, then tighten. A store that blocks 100% of fraud but also blocks 5% of real customers is losing more money than a store with a small, managed fraud rate.

If you're running a COD store and fake orders are your primary problem, start with OTP verification and partial payments — they solve the most common COD fraud patterns. For more on protecting your order flow, see our guide on behavioral risk scoring for COD fraud detection.
