Overview
A working product,
ready to go to production.

R3Fill is a purpose-built medication reorder management platform designed specifically for R3 Health, a team of experts providing individualized medical, beauty, and regenerative care. It automates the tracking, reorder triggering, and fulfillment workflow for patient regimens, eliminating manual follow-up and reducing the risk of patients running out of medication.

Unlike a traditional software engagement that begins with months of discovery, wireframes, and design, R3Fill is already built and live. A fully functional design demo exists today at r3fill.chernickyventures.com, with 14 screens, complete workflows, real injectable math, and role-based navigation for Admin, Fulfillment, and Provider roles.

This proposal outlines the plan to take R3Fill from its current demo state to a fully operational, HIPAA-compliant production system, complete with a real backend, database, automated reorder engine, and notification system.

Core Capabilities
Everything your team needs
to manage medication reorders.

R3Fill is built around the specific workflows of a specialty pharmacy and telehealth operation. It is not adapted from a generic project management tool.

Feature Description Status
Patient Profiles Full name, DOB, contact, shipping address, preferred pharmacy, internal MRN UI Complete
Regimen Management Oral and injectable regimens with dose, frequency, start date, and override controls UI Complete
Injectable Math Engine Calculates doses per vial, days covered, and projected run-out date from concentration + volume + frequency Backend Needed
Automated Reorder Triggers Creates reorder tickets 10 days (configurable) before projected run-out for each active regimen Backend Needed
Reorder Queue Sortable, filterable queue showing all pending reorders by urgency, vendor, and status UI Complete
Fulfillment Workflow Draft → Pending → Approved → Ordered → Shipped → Delivered → Closed, with tracking number support UI Complete
Escalation Logic Automatically escalates unprocessed tickets at 7 days, 3 days, and 1 day before run-out Backend Needed
Notifications Email and SMS alerts to staff; optional patient-facing "refill being prepared" notifications Backend Needed
Manual Overrides Pause, skip, replace early, or override run-out date per regimen item UI Complete
Audit Log Immutable record of every PHI access, status change, override, and login event UI Complete
Role-Based Access Admin, Fulfillment, Provider, and View-Only roles with enforced permissions Backend Needed
Reports & Dashboards Reorders due in 7/14/30 days, overdue items, bundle opportunities, vendor lead-time performance UI Complete
Settings Configurable lead times per vendor, notification templates, escalation rules UI Complete
Payment Structure
Tied to delivery,
not to time.

Each payment is tied to a specific, demonstrable deliverable. You only pay when something tangible is in your hands.

Total Project Investment

Name, Title, Date

What you'll have at completion: R3 Health receives a perpetual, irrevocable license to use the platform with no ongoing licensing fees. All GCP infrastructure, credentials, secrets, and documentation transfer to R3 Health in full. The platform runs entirely on R3 Health's own GCP account and domain, with no dependency on Chernicky Ventures, LLC after handoff. R3 Health has complete operational control.

Optional: Post-Launch Support Retainer. After the final milestone, ongoing support, bug fixes, and feature development are available on a monthly retainer basis. This is entirely optional (the platform is designed to run independently), but a retainer is available for teams who prefer a dedicated point of contact for questions, updates, or future development. Pricing available on request.

Questions? Reach out directly at zach@chernickyventures.com or schedule a call to walk through the demo together. The live product is the best starting point for any conversation.
