Fraud prevention tools

These fraud tools work best when combined with Shopify's built-in fraud detection and third-party fraud services.

What are Skio's fraud prevention tools?

How to set up spending limits

Spending limits apply at the customer level (across all of a customer's subscriptions) rather than individual subscriptions, giving you broader fraud protection.

Step 1: Navigate to Billing & orders settings

In the lefthand menu of your Skio Dashboard, go to Account > Settings > Billing & orders.

Step 2: Configure spending limits

1. Toggle on Enable spending limits.

2. Configure your spending limit settings:

   • Spending limit: The maximum total revenue a customer can process within the time window

   • Interval count: The number of intervals for the spending limit window (e.g., 30)

   • Interval: Choose days, weeks, or months

3. Click Save.

What happens when a customer exceeds the spending limit

When a customer exceeds your configured spending limit, their next queued order will be silently skipped without notifying the subscriber. Once the spending interval resets, their orders will process normally again.

Important: The customer's next billing date will not change when an order is skipped due to spending limits.

How to block customers with the customer blocklist

Use the customer blocklist to prevent known fraudsters from processing any orders through their subscriptions.

Step 1: Navigate to Customer Blocklist

In the lefthand menu of your Skio Dashboard, go to Tools > Customer Blocklist.

Step 2: Add a customer to the blocklist

1. Search for the customer email you want to block.

2. Click Add to blocklist.

What happens when a customer is blocked

Once a customer email is added to the blocklist:

• All orders tied to this customer will fail to process in Shopify.

• The customer can still log into their Customer Portal, but orders across all their subscriptions will be silently prevented from processing.

• Even if the customer changes their email address, they'll remain blocked—Skio uses the subscriber ID to maintain the block regardless of email changes.

This intentional design prevents blocked users from knowing they've been flagged, reducing the likelihood they'll attempt fraud with a new account.

How to create a spending limit segment

You can track which subscriptions have hit your spending limits by creating a dynamic segment in the Segments dashboard.

1. In the lefthand menu of your Skio Dashboard, go to Segments.

2. Click Create segment.

3. Add a condition for the audit log action: User was not billed because they exceeded the site's spend limit.

4. Set a date range (e.g., last 30 days relative to today, or all time).

5. Save your segment.

Once created, you can export the list of affected subscriptions and review customer emails to determine if they should be added to the customer blocklist.

Best practices for fraud prevention

Skio's fraud tools are most effective when used as part of a comprehensive fraud prevention strategy:

• Use third-party fraud detection: Tools like NoFraud provide additional layers of protection that Skio cannot replace.

• Optimize Shopify's fraud tools: Work with Shopify to configure their built-in fraud detection for your store.

• Monitor regularly: Create segments to track spending limit triggers and review blocked customers periodically.

• Set realistic limits: Configure spending limits that catch fraudulent behavior without impacting legitimate high-value customers.
