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.
Every return your portal auto-approves is a blind decision. Serial returners, wardrobers, and double-dippers exploit that gap , and every logistics app is built to process returns, not stop them. Kuror intercepts return requests before a label prints. It scores each request against a cross-merchant Global Fraud Ledger and auto-declines high-risk users or forces store credit - on autopilot.
- Block or hold orders from bad customers you've already identified.
- Discover bad customers that you didn't even know existed.
- Auto group customers with multiple accounts (e.g. different emails).
- Easily block any customer without needing complex fraud rules.
- Identify serial returners using crowdsourced data from across the Kuror network
- Set custom risk thresholds to auto-decline or flag returns for manual review
- Block bad actors using anonymous behavioral metadata without storing sensitive
