# Split/Full Pricing Toggle

## Where It Lives

Three separate components — each has its own copy:

| Location | Component | File |
|----------|-----------|------|
| Quote Generator | `ServiceRow` (memo) | `src/components/quoteGenerator/ServiceRow.tsx` |
| RO Create/Edit | `ServiceRow` (inline) | `src/components/ROForm.tsx` |
| RO Detail Modal | `EditableServiceRow` (inline) | `src/pages/RODetailModal.tsx` |

All three share the same toggle pattern. When adding the toggle to a new service row, copy the pattern from any existing one.

## Type Fields

Added to `Service` / `QuoteService` / `ROService` in `src/types.ts`:

```ts
pricingMode?: 'full' | 'split';
laborHours?: number;
laborRate?: number;
partsCost?: number;
```

`ROService` already had `pricingMode` and split fields. `QuoteService` extended `Service` to add them.

## Toggle Pattern

A pill-button group rendered in the row header:

```tsx
<div className="flex rounded-lg border border-gray-300 dark:border-gray-600 overflow-hidden text-xs">
  <button
    type="button"
    onClick={() => {
      if (isSplit) {
        onChange(index, 'pricingMode', 'full');
      }
    }}
    className={`px-2.5 py-1 font-medium transition-colors ${
      !isSplit
        ? 'bg-blue-600 text-white'
        : 'bg-gray-100 dark:bg-gray-700 text-gray-600 dark:text-gray-400 hover:bg-gray-200 dark:hover:bg-gray-600'
    }`}
  >
    Full
  </button>
  <button
    type="button"
    onClick={() => {
      if (!isSplit) {
        const flatTotal = service.total || total;
        const rate = defaultLaborRate;
        const hours = rate > 0 ? Math.round((flatTotal / rate) * 100) / 100 : 0;
        onChange(index, 'pricingMode', 'split');
        onChange(index, 'laborHours', hours);
        onChange(index, 'laborRate', rate);
        onChange(index, 'partsCost', 0);
      }
    }}
    className={`px-2.5 py-1 font-medium transition-colors ${
      isSplit
        ? 'bg-blue-600 text-white'
        : 'bg-gray-100 dark:bg-gray-700 text-gray-600 dark:text-gray-400 hover:bg-gray-200 dark:hover:bg-gray-600'
    }`}
  >
    Split
  </button>
</div>
```

### State Derivation

```ts
const isSplit = service.pricingMode === 'split'; // default Full
```

When `pricingMode` is undefined (existing data without the field), it defaults to **Full**.

### Mode Switch Behavior

| Switch | What Happens |
|--------|-------------|
| Full → Split | Derives `laborHours = flatten Total / laborRate` from the flat price. Sets `laborRate = defaultLaborRate`, `partsCost = 0` |
| Split → Full | Just sets `pricingMode = 'full'`. Split field values persist in state but are hidden |

### Full Mode Display
- Grid collapses to 2 columns: **Name** + **Total Price** (editable input for `service.total`)

### Split Mode Display
- Grid shows 5 columns: **Name**, **Labor Hrs**, **Rate/hr**, **Parts $**, **Total** (read-only, calculated)

## Total Calculation

`roServiceTotal()` in `src/lib/totals.ts`:

```ts
export function roServiceTotal(s): number {
  const split = (s.laborHours || 0) * (s.laborRate || 0) + (s.partsCost || 0);
  return split || s.total || 0;
}
```

For Full mode: hours=0 → split=0 → falls back to `s.total`. **Every call site must pass `total: s.total || 0`** to `roServiceTotal` — otherwise Full-mode services compute to $0.

## Where Total Must Be Passed

Search the codebase for `roServiceTotal` call sites and ensure `total` is in the argument:

- `ROForm.tsx` ServiceRow render — the `total` const used for display
- `ROForm.tsx` `computeROTotals` mapper
- `ROForm.tsx` `handleSubmit` cleanedServices mapper
- `RODetailModal.tsx` EditableServiceRow render
- `RODetailModal.tsx` service cleanup on save

## Initial Defaults

Every place that creates a new service must set `pricingMode: 'full'`:

| Location | File | Line |
|----------|------|------|
| ROForm edit path fallback | `ROForm.tsx` | ~385 |
| ROForm create path | `ROForm.tsx` | ~413 |
| ROForm handleAddService | `ROForm.tsx` | ~553 |
| RODetailModal handleAddService | `RODetailModal.tsx` | ~822 |
| RODetailModal createEmptyServiceForm | `RODetailModal.tsx` | 57-67 (already 'full') |
| QuoteGenerator ServiceSearch handleAdd | `ServiceSearch.tsx` | 56 (addService passes defaults) |

## Persistence

When saving services back to PocketBase, `pricingMode` must be included in the cleaned service object:

```ts
pricingMode: (s.pricingMode || 'full') as 'full' | 'split',
```

This is in:
- `ROForm.tsx` handleSubmit cleanedServices
- `RODetailModal.tsx` service save handler
