Offer a per-incident resolution service that assembles proof of attempted payment, identifies institution-approved alternatives, prepares escalation messages, and guides or joins customer-support calls. After the immediate issue, the service confirms posting or cancellation and helps request correction of related fees or payment records without taking custody of funds or bank credentials.

Consumers increasingly depend on self-service banking channels, while the signals show failures recurring across multiple institutions and both mobile and website workflows. A manual concierge can validate demand before developing reusable case-management and evidence-capture tools.
