Failed Payment Rescue — Recover Revenue From Billing

Initial state: Supplied invoice/attempt record only. “Authentication required” is a provider label whose exact meaning and recovery flow require verified documentation.

Gate 1: Confirm invoice identity, amount, current due state, subscription status, customer authorization and any dispute or cancellation. Do not treat a failed charge alone as permission to collect.
Gate 2: Check for newer successful attempts or duplicate-processing risk before any action.
Gate 3: Verify the provider’s authentication flow, permitted communication and stop rules. No retry timing invented.

Proposed recovery path: If the charge is legitimate and due, use the provider-supported secure customer-authentication route under authorized policy. Never request raw card security codes or secret payment credentials in ordinary messages.

Customer message draft: “Your latest subscription payment could not be completed. If this invoice is still due and authorized, please use our verified secure billing process to review the payment and any required authentication. Contact support if the charge is unexpected.” Confirm details and secure route before sending; no link fabricated.

Stop/escalate: Dispute, cancellation, unauthorized charge, policy restriction or uncertain state requires human billing review. Do not retry aggressively or bypass controls.

Measurement: Record verified invoice resolution and successful paid amount only after evidence. Failed attempts and messages are not recovered revenue.

Execution: Workflow draft only. No billing access, authentication link generated, message sent, retry attempted or revenue recovered.
