The Billing & Invoicing system streamlines financial documentation by automatically generating itemized invoices from clinical notes or allowing manual bill creation with preset templates.

​
Overview

Billing supports two primary workflows:

AI-Generated Invoices

Automatically extract billable items from SOAP notes using AI, then review and adjust before finalizing

Manual Invoice Creation

Build invoices from scratch or use predefined templates for common visit types

​
Bill Item Types

All billable items are categorized into 8 standard types:

​

​
AI-Powered Invoice Generation

The system can automatically generate bills from SOAP notes:

​
How It Works

  1. Trigger AI generation: Click “AI Generate” button
  2. AI analyzes SOAP notes: Extracts procedures, medications, diagnostics from clinical documentation
  3. Matches to billing codes: Maps clinical activities to billable item types with standard pricing
  4. Presents for review: Displays generated invoice in editable table format
  5. Staff reviews and adjusts: Modify quantities, pricing, or add/remove items as needed
  6. Finalize: Lock invoice for payment processing
const handleGenerateAI = async () => {
  setIsGenerating(true);
  // AI analyzes SOAP notes and extracts billable items
  await new Promise(r => setTimeout(r, 1500));
  setBillItems(TEMPLATE_PRESETS.wellness);
  setIsGenerating(false);
  setSuccess('Billing items generated from SOAP notes');
};
Always review AI-generated invoices before finalizing. The system may not capture all nuances of the visit or may suggest items that weren’t actually performed.

​
Manual Invoice Editing

​
Bill Items Table

Interactive table for adding and editing line items:
ColumnInput TypeDescription
Item NameText inputDescription of the billable item
TypeDropdown selectOne of 8 item type categories
QtyNumber inputQuantity of items (minimum 1)
Unit CostNumber inputPrice per unit in dollars (supports decimals)
TotalCalculated displayAuto-calculated: Qty × Unit Cost
ActionsDelete buttonRemove item from invoice

​
Adding New Items

  1. Click “Add Item” button below the table
  2. New blank row appears at bottom
  3. Fill in item details: 
    {
  id: Date.now(), // Unique identifier
  name: '',
  type: 'Other',
  quantity: 1,
  unitCost: 0,
  total: 0
}
  4. Total auto-calculates as you enter quantity and unit cost

​
Editing Existing Items

  • Click in Qty column
  • Enter new number
  • Total recalculates automatically
if (field === 'quantity' || field === 'unitCost') {
  updated.total = Number(updated.quantity) * Number(updated.unitCost);
}

​
Financial Calculations

The system displays three calculated totals:

Subtotal

Sum of all item totals before tax
const subtotal = billItems.reduce(
  (sum, item) => sum + (item.total || 0), 
  0
);

Tax

Configurable tax rate applied to subtotal
const TAX_RATE = 0.0; // 0% by default
const tax = subtotal * TAX_RATE;
Most veterinary services are tax-exempt. Adjust TAX_RATE constant if your jurisdiction requires sales tax.

Total Due

Final amount owed by client
const total = subtotal + tax;
Displayed prominently in large green text

​
Currency Formatting

All monetary values use US dollar formatting: 
const formatCurrency = (amount: number) =>
  new Intl.NumberFormat('en-US', {
    style: 'currency',
    currency: 'USD'
  }).format(amount);
Example output: $208.00

​
Notes Field

Free-text area below the bill items for:
  • Payment terms and conditions
  • Discount explanations
  • Special instructions for client

Best Practices

  1. Ensure complete SOAP notes: AI extracts from clinical documentation, so thorough notes = accurate bills
  2. Review every AI suggestion: Don’t blindly accept generated items
  3. Check quantities: AI may default to 1× for all items; adjust multi-day medications
  4. Verify pricing: Ensure unit costs match current fee schedule
  5. Add manual items: Include any procedures/supplies not captured in SOAP notes
  • Standard fee schedule: Maintain a reference document with current pricing for all services
  • Regular updates: Review and update template pricing quarterly
  • Special pricing: Document any client-specific discounts or payment plans in notes
  • Supply costs: Track consumable supply costs to ensure margins are maintained
