The Network Advantage

Fraud intelligence that grows with every delivery

Preventify's risk model is powered by Courierify — a courier and fulfilment network processing millions of COD deliveries. Every outcome (delivered, refused, ghost) feeds the model. The more stores use it, the smarter it gets.

How It Works

From order submission to risk decision — in under a second

01

Buyer submits form

Customer fills the COD form and hits "Place Order". Their phone number and device fingerprint are captured.

02

Network lookup

Preventify cross-references the phone + device against the Courierify network of delivery outcomes.

03

Score computed

A 0–100 risk score is generated in real time, factoring in past refusals, ghost orders, device changes, and order velocity.

04

Action triggered

Based on your configured thresholds, the order is accepted, sent to review, held, or cancelled — automatically.

Device Fingerprinting

Phone numbers change. Devices don't.

Fraudsters know to swap SIM cards. Preventify fingerprints the device itself — browser, screen, hardware signals — so a blocked buyer can't just use a new number to sneak back in.

  • Browser-level fingerprintCaptures a unique identifier from the device without cookies — works even in incognito mode.
  • Cross-phone detectionIf a device has placed fake orders under multiple phone numbers, all future orders from that device are flagged.
  • Order velocity detectionMultiple orders from the same device in a short window are automatically escalated for review.

Smart Actions & Block List

Automate your fraud response — your rules, your thresholds

Configure score thresholds that trigger automatic actions. Review manually when you need nuance, or set aggressive auto-block rules for your highest-risk score bands.

  • Threshold-based rulesSet 0–100 score bands with different actions: accept, flag for review, hold, or auto-cancel.
  • Manual block listAdd specific phone numbers or devices to a permanent block list — they can never order again.
  • Review queueMedium-risk orders drop into a review queue in your dashboard — approve or reject in one click.
  • Shopify order tagsRisk score and action are written as Shopify order tags for downstream filtering and reporting.

Common Questions

Frequently asked

What is RTO and why is it such a problem for COD stores?
Return-to-Origin (RTO) happens when a COD order is shipped but the buyer refuses delivery or isn't reachable. You pay shipping both ways and get nothing. RTO rates of 20–40% are common in Pakistan and South Asia, directly eating into margins.
How does Preventify know a buyer is high risk?
The risk score is built from delivery outcomes (accepted vs refused) collected across millions of COD orders processed by Courierify's courier network. Phone numbers and device fingerprints with a history of refusals receive higher scores.
Will blocking high-risk buyers cause me to lose real customers?
You control the thresholds. We recommend starting with a "review" action for mid-range scores (60–80) and auto-block only above 85. Most stores find the false-positive rate negligible at that threshold — and you can always whitelist a specific number.
Does the score work for buyers outside Pakistan?
The network data is heaviest for Pakistan, UAE, and KSA at this stage. For other markets the device fingerprint and velocity signals still apply, and the model continues to grow as more orders flow through the network.
Is OTP required to use fraud prevention?
No — OTP and the risk score are independent features you can enable separately. Many stores run risk scoring on all orders and only trigger OTP for medium-risk ones to minimise friction for genuine buyers.
