our call
Start with Returnless — highest vibe code, weakest moat.
Corso
Building the checkout upsell widget and customer claims form in Next.js/Shopify UI Extensions takes less than a week. However, Corso functions as a managed operational layer that adjudicates lost/stolen package claims, funds replacements, and procures certified carbon offsets. Rebuilding the software is trivial; replacing the insurance risk pool and operational claims team is not.

- Checkout UI extension for opt-in package protection and carbon offset fees
- Customer-facing self-service return and damage claim submission portal
- Automatic re-order triggering via Shopify Admin API upon claim approval
- Rule engine for basic return eligibility based on order date and product type
- Merchant analytics dashboard showing protection revenue and claim counts
what you lose
- Outsourced claims desk handling customer dispute resolution and verification
- Turnkey procurement and retired registry audit trail for carbon offsets
- Financial underwriting covering catastrophic spikes in package loss or theft
- Pre-negotiated carrier integration for automated return label generation
- Historical risk models for flagging fraudulent shipping claims
