# One event, one kitchen-ready pack the whole brigade trusts.

Generate the BEO, guest menus and allergen matrix from one event record. Havenue checks every dish against each guest, finds suitable replacements from your verified recipes, and keeps them ready for chef approval.

Havenue does more than display allergens. It checks the dishes on the event against every guest's requirements using verified ingredient data, identifies suitable replacement dishes from your own recipes, and generates the operational documents from the same event record. Guest count, date, deposit, room, notes, costs, guest menus, the BEO and allergen matrix stay aligned through chef review and sign-off.

## The problem this solves

When the run-sheet, the allergen list and the guest menus live in separate files, they drift apart, and a last-minute change leaves the kitchen guessing. Havenue keeps the BEO, the guest menus and the allergen matrix generated from the same event, so a change in one is a change in all.

## How it works

1. **Generated from the event** : The BEO pulls guest count, date, deposit, room, notes, special requirements and dietary needs from the event record, with no retyping.
2. **Resolve before service** : If a dietary guest has no safe dish, resolve it in one place and the BEO, guest menus and matrix all update together.
3. **Check the allergen matrix** : Every dish sits against the 14 allergens, built from your saved recipe and ingredient data, with an ingredient-level breakdown you can expand.
4. **Sign off and keep the history** : Approve the pack and the sign-off is tied to that exact version. Every earlier generation stays in version history to view or export.

## What you get

- **A real BEO, not a bare sheet** : Guest count, deposit, room, notes, special requirements and dietary context in one kitchen-ready document, pulled live from the event.
- **Allergen review made repeatable** : Dishes against the 14 allergens, built from saved recipe data rather than a guess, with the ingredient behind every flag.
- **Built to support food safety** : Ingredient-level traceability and a clear needs-review flag help your team prepare allergen information with care before service.
- **Accountable version history** : Every generation is saved. Sign-off records who approved which version, with date and time, so a later edit cannot quietly undo it.
