Card-testing bots and fake orders keep landing on small Shopify stores' fraud queues, and merchants can't isolate them: bulk authorization attempts, mismatched billing/shipping info, and disputed charges that eat into thin margins. Eleven distinct Reddit threads have Shopify sellers asking for something purpose-built to catch this pattern before it becomes a chargeback — not a general fraud score, but a filter tuned to card-testing behavior at checkout. It matters because chargebacks carry fees on top of the lost goods, and repeated disputes put a store's payment processing at risk. The ask keeps resurfacing because merchants haven't found a tool that closes the gap cleanly.
