The scope of the Mochi Health Billing Page design involves creating a system for patients to manage subscription and payment details, insurance, and pharmacy preferences. Similarly, care-coordinators need tools for resolving billing inquiries and managing patient details, while providers require access to patient information and pharmacy updates. To realize this, integration with tools like Chargebee, Stripe, Dosespot, and Plaid is mandated. The design of CRM software for tracking patient inquiries is outside of this project's scope.
