# Discount settings wiring audit
The Discount tab is persisted through `SettingsHelper` in the `discounts` group and rendered from `config/discount-promotion-settings.php`.
## Public booking/runtime wiring
- Deal records and promo codes are applied by `BookingController` and `DynamicPricingService` when a valid deal/rate-plan discount is supplied.
- Dynamic pricing has separate financial settings for early-bird and last-minute discounts.
## Company-admin (non-Filament) wiring
- Admin invoice forms support explicit per-line discount amounts.
- Admin deal management creates and edits deal records, including seasonal and last-minute deal types.
- The company-admin booking creation flow does not apply the Discount tab’s general, group, long-stay, loyalty, referral, or coupon settings automatically.
## Settings currently saved but not consumed consistently
- `enable_discounts`, `allow_multiple_discounts`, `max_discount_percentage`, and `require_coupon_code`.
- Early-bird, last-minute, group, long-stay, loyalty, seasonal, and referral toggles and thresholds.
- Coupon expiry, stacking, and case-sensitivity controls.
These settings are separate from venue/rate-plan discounts and therefore changing them does not reliably affect either public or non-Filament admin booking totals. The existing deal and dynamic-pricing paths remain functional.
## Implementation update
A centralized DiscountSettingsService now applies company discount switches for early-bird, last-minute, long-stay, group, maximum percentage, and coupon-required rules during public booking creation. It is reusable from non-Filament admin booking flows.
