Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBlox stops repeat chargebacks, refund abuse, and serial returners before they place another order. On install, Blox imports your order and chargeback history automatically, so customers with past chargebacks are identified from day one. Customers using multiple emails or accounts are merged into one profile. When one merchant flags a fraudster, the community-powered blocklist protects every Blox store.
Refund abuse and chargebacks drain merchant profits, but most stores have no way to identify repeat offenders before processing a refund. Chargeback Shield scores every order automatically using refund history, purchase patterns, and cross-store fraud signals. Risky orders appear in a review queue with plain-English explanations. Risky fulfilments are held automatically until you decide.
