DoubleDip Shield: Return–Chargeback Sync & Auto-Evidence
The Opportunity
Prevents double-dip fraud by matching returns with disputes in real time across payment gateways. Automatically holds refunds, alerts teams, and files tailored evidence bundles to win chargebacks when a return is in progress or completed.
"Fraudsters file a return and a chargeback for the same order, causing merchants to lose both inventory and revenue, with only a small window to react."
Market Validation
Detailed Analysis
Proposed Solution
Continuously sync refunds/returns with dispute data from Shopify Payments, Stripe, and PayPal; match events to the same order; automatically pause refunds until dispute resolution and submit evidence (RMA numbers, communications, tracking/proof-of-delivery) using gateway APIs; route high-risk cases to manual review.
Target Audience
Merchants processing at scale (5k+ orders/month) with notable dispute rates, especially apparel, footwear, electronics, and marketplaces.
Competitive Landscape
Chargeflow, Midigator, PayPal Chargehound, Signifyd, Riskified
Implementation Notes
Subscribe to Shopify webhooks for returns_create, refunds_create, disputes_create (Shopify Payments) and mirror with Stripe Disputes API and PayPal Disputes API; build a matching engine by order ID, payment intent ID, customer identifiers, and timestamps; implement rules to auto-hold refunds when a dispute is detected and to auto-cancel RMAs when chargeback is lost; generate evidence packets with order details, return labels, RMA IDs, tracking scans, photos, and customer communications; offer prebuilt evidence templates per gateway reason code; provide SLA-driven alerts (Slack, email) and a queue UI; secure PII, maintain audit logs, and support multi-gateway accounts.
Evidence from Merchants
Real quotes from Shopify community forums
"The patterns that are hardest to catch manually: Reason switching — The same customer uses 'defective' one time, 'wrong item' another, 'didn’t fit' another."
"Double-dip fraud — Customer submits a return and files a chargeback for the same order."
"By the time a return is requested, you’ve already shipped."
"Customers who consistently return just under amounts that would trigger manual review."
"I’m currently looking for beta testers — merchants getting 50+ returns/month who want to try it free."
