The Challenge

The Pain
We Solved

A premium clinic was managed through Excel spreadsheets, manual Telegram messages, paper records, and three disconnected services for scheduling and billing. Every expansion of the service catalog turned into an operational meltdown.

Before Us
  • ×
    Appointments in Google Calendar + admin Telegram chat. Slot conflicts, forgotten confirmations, lost patients.
  • ×
    Patient records were paper files. Finding a medical history took 10 minutes. Sharing with a remote doctor was impossible.
  • ×
    Service pricing lived in an Excel spreadsheet with 15 columns for different hair lengths. Receipt errors occurred weekly.
  • ×
    Ampoule inventory was tracked by guesswork. Orising and Revivre batches expired without warning — losses of $ 500/mo.
  • ×
    Zero analytics. No way to tell which service was profitable, which doctor was overloaded, or which channel brought patients.
  • ×
    SOAP encounters were stored in Word documents. Doctor signatures, ICD-10 codes, and versioning were nonexistent.
After Us
  • ✓
    Calendar with buffer times and conflict checks. Rooms, equipment, assistants — all in a single appointment view.
  • ✓
    Full-featured EMR with 13 tabs — from trichology profile to hair diary and audit log.
  • ✓
    Service catalog with tiered pricing by hair length, seasonal multipliers, and full change history.
  • ✓
    Batch-level inventory with auto-deduction per procedure and LOW_STOCK / EXPIRING_BATCH alerts.
  • ✓
    AI analytics and 8 monitoring alert types — the system proactively notifies when something goes wrong.
  • ✓
    Digital SOAP with ICD-10, templates, AI summarization, and record locking after signature.

  • 4 severity levels — INFO / SUGGEST / WARN / URGENT
  • 8 monitoring rule types — from LOW_STOCK to LEAD_RESPONSE_SLA
  • 3 delivery channels — Dashboard, Email, SMS
  • Direct links to reports — open report, go to batch, create campaign

A Calendar That
Thinks for the Reception

A calendar slot is not just a time. It is the intersection of doctor × room × equipment × assistant, with setup/cleanup buffers and automatic conflict detection. Every appointment change goes into AppointmentChange — audit trail.

  • 5 statuses — Scheduled → Confirmed → In progress → Completed / No-show / Cancelled
  • Multi-service in a single visit with different assistants
  • Discounts & promo codes applied directly in the appointment card
  • Recurring — procedure series with auto-generated appointments

Premium-Grade
Electronic Medical Record

The patient card in VOZNA is a full-featured EMR with 13 tabs. Medical history, lifestyle, hormones, family history, documents, plans, trichoscopy, labs, hair diary, AI insights, and consents with e-signature. Everything in a single view.

  • History vitae & morbi with ICD-10, allergies (severity / reaction), chronic conditions
  • Gynecological & hormonal panel: cycle, PCOS, thyroid, lactation
  • Patient wallet with transactions · loyalty tiers Bronze → Gold
  • Tag system: VIP, PLATINUM, allergic, nursing — for marketing segmentation

Service Catalog
with Tiered Pricing

13 types of trichology services, 5 pricing tiers by hair length, 4 consumable brands (Orising, Revivre, Full Force, Na Golovy), and full price change history. The price list is no longer an Excel sheet —  it is a managed catalog with a complete audit trail.

  • Seasonal multipliers and promo periods
  • Product consumption per procedure — auto-deduction from inventory
  • Compatibility with rooms and equipment
  • Instructions before/after procedure, photo gallery, service packages

SOAP Encounters
as a Medical Standard

Every encounter is documented according to the international SOAP standard — Subjective / Objective / Assessment / Plan. Diagnoses are linked to ICD-10, AI suggests options with a confidence score, templates speed up routine cases, and the record locks after the doctor’s e-signature.

  • SOAP templates — 30 seconds to document a routine encounter
  • AI summarization automatically generates an encounter summary
  • Lock trail — after signing, edits only via amendment
  • Linked to trichoscopy, photo zones, and treatment plan

AI Layer
of Five Modules

This is not a "built-in GPT." It is a set of narrow clinical tools with clear input/output contracts. Each operates on the specific clinic’s data and respects privacy by default.

  • Diagnostics — ICD-10 suggestions with confidence scores
  • Insights — auto-detect patterns: revenue, no-show, utilization
  • Anomalies — monitoring deviations in clinic data
  • Chat — contextual assistant with intent detection
  • Summarization — SOAP encounter summary in one click

Billing, Inventory,
Loyalty — All in One

Billing is tied to inventory. The moment a doctor completes a procedure, ampoules are deducted from the batch by serial number, an invoice is generated, loyalty points are credited, and the patient’s loyalty tier is updated.

  • Invoice lifecycle — Draft → Issued → Paid / Partial / Overdue
  • Multi-payment — cash, card, transfer · fiscal receipt
  • Promo codes with limits and gift certificates with balance
  • Batch-level tracking with serial numbers and auto-LOW_STOCK
  • Bronze → Silver → Gold with cashback and referral program

Logs, Audit,
Data Discipline

A premium clinic means not just service, but accountability. Every action in the system is recorded in the AuditLog: who, what, when, IP, UserAgent, justification, and a diff of changes. Safe for patients, legally robust for the clinic.

  • Sterilization log with method, duration, and indicator
  • Waste disposal by class with weight
  • Equipment maintenance log with service schedule
  • AuditLog — every action · diff · hash-chain
