Pre-launch · Private audit cohort, 50 stores

The native Shopify app that turns return losses into retained margin.

Read-only webhook access. No theme code injection. GDPR compliant. Hand-reviewed PDF within 48 hours. No credit card.

02How we detect

Four patterns.
Four mechanisms.
No vague "AI."

Each detection method is deterministic and explainable. You read the rule that flagged a customer. You override it in one click. Risk scoring is advisory — never autonomous.

Wear-then-return

Wardrobing

Returns that arrive 7–14 days after delivery, repeatedly within categories where wear is non-obvious (apparel, footwear). We weight by reason-code drift across orders.

Catches the 69% of shoppers who admit to single-use wear.

Buy-many-keep-one

Bracketing

A single order containing 3+ size or color variants of the same SKU, where partial returns happen within the typical try-on window.

The 51% Gen Z behavior that erodes apparel margin invisibly.

Repeat offender

Serial returners

Return-to-order ratio above 60% over a 90-day rolling window, weighted against retained lifetime value so VIP customers are exempt.

Surfaces the 3% of accounts driving the bulk of leakage.

Identity laundering

Multi-account abuse

Device fingerprint clustering across canvas data, IP rotation history, and disposable-email domains — links seemingly unrelated buyers to one entity.

Defeats blocklist evasion via new emails and addresses.

↳ From a Shopify merchant

"Same customer whose reasons shift from "wrong size" to "defective" to "not as described" across orders. One reason is fine. Three different reasons in four months is a pattern."

03Who's behind this

Built by an independent
e-commerce engineer.
Zero VC pressure.

ReturnSage is bootstrapped and customer-funded. There is no investor demanding 10× growth, no SDR team to upsell you into a tier you do not need. The roadmap is set by the merchants paying monthly — and it is focused on one thing: protecting your margin without slowing your store.

Currently analyzing 11,089 merchant data points from public Shopify reviews and community forums to refine the detection engine before launch.

Data & security policy

  • Read-only webhooks. We never write to orders, customers, products, or theme code.
  • Zero theme injection. No script tags, no Liquid edits, no checkout interception. Uninstall is clean.
  • PII purge on uninstall. Email, IP, and fingerprint data deleted within 30 days of app removal. GDPR + CCPA compliant.
  • No cross-merchant pooling. Your customer behavior data is never aggregated into a shared blocklist or sold.
  • Decision support, not autopilot. ReturnSage tags risk and shows the evidence. The merchant approves every blocked return.

05FAQ

Frequently asked.

No. ReturnSage runs entirely on backend webhooks, asynchronous to your checkout flow. We never inject anything into the checkout pipeline, so your Core Web Vitals and conversion rate are untouched.
