Automated affiliate commission clawbacks with ledger-first design

Executive Summary

Affiliates get paid on conversion, then customers refund later, forcing manual clawbacks and reconciliation. Build a ledger-first payout system that records earned-but-not-finalized commissions, auto-reverses on refund webhooks, and provides audit trails. Payment platforms now expose reliable webhook events and metadata (for example Stripe charge and refund webhooks) that let systems detect refunds in real time, enabling automated reversals instead of manual reconciliation. Market context from the dev.to post emphasizes the developer/operator pain of not designing the ledger first, which is solvable today through event-driven architectures and serverless functions. E-commerce return rates and growth of affiliate programs across platforms like Shopify and marketplaces make refunds a common, recurring workflow that demands automation and auditability now. Position as a ledger-first affiliate reconciliation layer that integrates payment processor webhooks (example: Stripe and PayPal refund events) and partner platforms to record earned, pending, and settled commission states. The dev.to source explicitly recommends designing the ledger first to make reversals deterministic, so this product uses an immutable event ledger and idempotent webhook processing to guarantee correct state transitions and audit trails. By storing time-series commission state per referral and linking to charge and refund events, the product becomes the single source of truth for both finance and partner ops, enabling predictable automated clawbacks and dispute resolution.
