Practical playbooks on fraud prevention, checkout optimization and EU compliance — written by the team behind our apps.
Stopping Scalper Bots on Limited Drops
Limited drops attract scalper bots that clear inventory in seconds and leave real fans empty-handed. Learn the tactics scalpers use, and the queues, rate limits, and checkout controls that make your drop fair again.
Empty-Box & Switch Return Fraud
Return fraud costs merchants billions—empty boxes, swapped items, and worn goods sent back for full refunds. Learn the common tactics, build an inspection SOP, and flag serial returners before they drain your margin.
Free vs. Paid Fraud Apps: What You Actually Get
Free fraud apps do real work, and paid tiers are not just upsells. The question is where the line falls for your store. Here is a clear breakdown of what each gives you and when upgrading pays off.
Preventing First-Party (Friendly) Fraud
Friendly fraud is the customer who really did order, really did receive it, and disputes anyway. You can't detect your way out of it, you have to prevent it with delivery proof, clear descriptors, and proactive communication.
Translating Your Withdrawal Form for the EU
Selling across the EU means presenting the withdrawal right and model form in the language your customer understands. Learn the language obligations, how to translate the model form, and per-market presentation.
CGNAT & Mobile Carrier IPs: Block or Allow?
Thousands of mobile shoppers can share a single IP address thanks to carrier-grade NAT. Learn how CGNAT works, why blocking a mobile IP can shut out hundreds of real customers, and how to filter fraud without over-blocking.
How to Block an IP Address in Shopify (2026 Guide)
Step-by-step guide to blocking IP addresses on Shopify in 2026 — using Shopify Functions, free apps, and country-level rules to stop fraud, bots, and abusive visitors.
EU Withdrawals vs. Chargebacks: Handling Both
A lawful right-of-withdrawal cancellation and a payment chargeback look similar but are fundamentally different. Here is how each one works operationally and the workflows your Shopify store needs for both.
How to Block a Country in Shopify (Complete 2026 Guide)
Block visitors and orders from any country in Shopify without code. Learn country blocking, geo-redirects, and how to allow only selected regions for free.

Fraudsters lean on VOIP and burner numbers to pass phone verification and hide their identity. Learn the signals that flag disposable numbers at checkout and the verification steps that catch them.
Fraud Prevention for Tickets & Events
Ticket sales live and die in the first 90 seconds. Scalper bots, high-demand drops, and resale abuse can drain your inventory before real fans arrive. Learn how to keep tickets in human hands and out of the resale racket.
Who Pays Return Shipping Under EU Law?
When a customer withdraws, who covers the return shipping? EU law has a clear default and important exceptions. Learn when the seller must pay and how to state your policy correctly.
