Practical playbooks on fraud prevention, checkout optimization and EU compliance — written by the team behind our apps.
Blockly vs. Signifyd: A Fair Comparison
Signifyd and Blockly solve fraud from opposite ends: one guarantees chargebacks, the other blocks bad traffic before checkout. Here is an honest look at how they differ and which fits your store.
Withdrawal vs. Legal Warranty in the EU
The 14-day right of withdrawal and the 2-year legal guarantee are two different consumer rights that merchants constantly confuse. Here is how they actually differ.
Stopping Image & Content Theft
Competitors lift your product photos, descriptions, and reviews to build their own listings on your dime. Learn practical defenses—hotlink protection, scrape deterrence, and watermarking—to protect your store's content.
Representment Evidence Templates
Winning a chargeback comes down to the evidence packet you submit. Use these reusable representment templates by reason code to build compelling responses fast.
Pre-Contractual Information: An EU Checklist
Before a customer clicks buy, EU law requires you to disclose a specific set of information. Miss items and your withdrawal window can extend by up to a year.
A Fraud Escalation Matrix for Teams
When a suspicious order lands, who actually decides? A fraud escalation matrix maps risk and order value to the right decision-maker so nothing stalls and nobody overrides above their pay grade.
Do You Need a WAF for Shopify?
Shopify already runs a platform-level firewall you cannot configure, so a traditional WAF is not what most merchants actually need. Here is what the platform covers and where an app-layer filter fills the real gaps.
Block Every Country Except the EU on Shopify
Learn how to run an EU-only Shopify store using an allowlist strategy, so every non-EU country is blocked by default. Covers the fraud, tax, and compliance reasons for tightening your storefront's geography.
Chargeback Ratio Benchmarks by Industry
What counts as a healthy chargeback ratio depends heavily on your vertical. Here are illustrative benchmark ranges, the danger thresholds that trigger card-network programs, and how to compare your store fairly.
Chargeback Reason Codes Explained
Every chargeback arrives with a cryptic reason code that tells you why the bank reversed the sale. Learn the major card-network families, what each really means, and how to respond.
Detecting Triangulation Fraud
Triangulation fraud hides behind a fake storefront and stolen cards, leaving your store as the fulfillment engine. Learn how the scheme works, the signals to watch, and the checkout controls that stop it before shipment.
The Digital Services Act & Shopify Sellers
