Menu engineering — the recipe card behind your menu

Star. Puzzle. Workhorse. Dog.Every dish on your menu, classified in one service.

Rongo costs every plate from the recipe card — sub-recipes, trim loss, cooking yield —, crosses your POS sales and classifies the menu on the Kasavana & Smith matrix. 30% food / 25% beverage targets, computed live.

Verified — the imports

Rongo reads the actual exports from your POS and purchasing: Agilysys InfoGenesis (HGD PBD/CBD), NAV, requisitions and comps. Every file is hash-deduplicated, archived and replayable.

The field

Built for the Polynesian field — from the independent restaurant to multi-outlet hotel operations, room service included, where island freight makes every food cost decisive.

02The leakage

A Dog kept out of habit costs you every month.

You know the service's revenue, rarely the plate's margin. Food cost sleeps in a spreadsheet recomputed at close: one supplier price moves, the margin drifts, and nobody sees it before month end.

  • The spreadsheet is recomputed once a month — the drift is daily.
  • Popular doesn't mean profitable: without crossing popularity and margin, you keep Dogs.
  • POS exports re-keyed by hand: hours spent on a reading already stale.

A menu is steered at the plate, not at the top line.

03The recipe card

The plate's cost builds up line by line.

Nested sub-recipes, trim loss, cooking yield: Rongo keeps the cost per portion current as soon as a purchase price moves — and breaks the selling price into net, service and VAT, the way your controller does.

  • A sub-recipe (stock, sauce, pressed base) is costed once and reused everywhere.
  • Loss and cooking yield applied per ingredient — the displayed cost is the cooked, plated cost.
  • A purchase price changes in NAV: every affected card recomputes.

Hotel-style net / service / VAT breakdown — annotated on every card.

04Cost control

Real food cost, held daily — not at close.

The matrix says what to change on the menu; cost control says whether the kitchen holds its costs. Rongo reconciles requisitions, comps and each outlet's revenue, every day, against targets.

requisitioncomps÷revenue=real food cost

The F&B controller's formula, computed per outlet and per family (food / beverage), daily.

  1. Daily cost control

    Drift shows the same day

    Ratio per outlet against target, with a status: green under target, orange up to 5 points above, red beyond. The daily trend replaces the month-end surprise.

  2. POS linking

    Every dish sold linked to its card

    Rongo links your POS items to recipe cards by similarity score. Whatever stays orphaned raises an alert — nothing leaves the matrix silently.

  3. Kitchen validation

    No card moves without review

    Draft, review, approval: the workflow traces who changed what, with dedicated kitchen roles. Six roles, automatic audit log.

05The alcohol price cap

The DGAE price cap, watched bottle by bottle.

In French Polynesia, alcohol selling prices are capped by a coefficient on the purchase price. Rongo computes each reference's ceiling price, compares it with your menu price and logs every gap — compliant, warning, violation, with the gap in francs.

Rongo watches and alerts; filings remain yours.

FAQ

The questions we actually get

It's the hospitality-school menu engineering method: every dish is crossed on two axes — its popularity (share of sales) and its margin per portion — then classified Star (popular and profitable), Puzzle (profitable but low-selling), Workhorse (popular but low-margin) or Dog (neither). Rongo computes this classification automatically from your POS sales and recipe cards, per outlet, with thresholds recomputed on your actual figures.

From the recipe card: every ingredient is costed against your real purchase prices, with trim loss and cooking yield, nested sub-recipes included. Cost per portion and the food cost ratio recompute whenever a purchase price changes, against the 30% food and 25% beverage targets — with a suggested selling price.

Rongo imports actual exports from Agilysys InfoGenesis (HGD PBD/CBD files), NAV purchase prices, plus requisitions and comps in Excel. Every file is hash-deduplicated, archived and replayable. No real-time POS connection is required: you load the export, Rongo does the matching.

No. Rongo is built precisely to take over what exists: your recipe cards are entered once (or taken over with our assistance on the Hotel and Group plans), and your monthly flows — POS exports, requisitions, comps — are the same files you already handle, imported instead of re-keyed.

On the F&B controller's formula: (requisition − comps) ÷ revenue, per day, per outlet and per food / beverage family. The ratio is compared with the outlet's target: green under target, orange up to five points above, red beyond. Drift shows the same day, not at close.

The alcohol price cap: Rongo computes each reference's ceiling price (coefficient applied to the purchase price), compares it with your menu price and logs every gap with a compliant, warning or violation status, and the gap in XPF. It does not file declarations for you: it guarantees you never sell above the cap unknowingly.

Nobody without a trace. Cards follow a draft → review → approval workflow, with six distinct roles — including dedicated kitchen roles — and an automatic audit log. You know who changed what, when, and what went to review.

Each property is partitioned at the database level itself (strict multi-tenant isolation, enforced by the database itself and covered by a dedicated integration test suite). Your cards and margins never cross another client's. Support runs from Tahiti, on your timezone.

The monthly subscription depends on the number of outlets and the volume of recipe cards. There is no public price until the grid is settled: request it via the form at the bottom of the page — it's sent in writing within 24 hours.

Yes — and nothing more. The section 06 inventory is exhaustive: this page only sells what runs in production today, no “coming soon” features. If a specific need is missing, say so in the demo — that's exactly what feeds the roadmap.
