Menu pricing for fast-food chains

We price your menu, store by store, for your long-term goals.

For chains, franchisors and franchisees with 20 to 200 locations who set their own prices. Every change we recommend is measured against stores that kept theirs.

Start with a free margin audit of your own numbers. Yours to keep either way.

What Pretaris does

One export in. A letter out.

  1. 01

    You send your sales history

    The sales history your POS already holds. Nothing to install, nothing to run, no change to how your stores work.

  2. 02

    We work out the price for each store

    The dashed line is one price everywhere. The dots are what each location should charge, read from what your own guests actually pay.

  3. 03

    You get a short letter

    Every few months: the few changes worth making, what each should earn, and the measured result of the last ones.

What you actually get

An example of your letter.

It arrives every few months. Not a dashboard you have to remember to open: a few pages that say which prices to change, at which stores, and what each change should earn. Where we're not sure, we say so and run a test first.

Pretaris Decision letter · September 2026
For a 40-store chain (sample)

Hello both,

Here's what we'd change this quarter, and one thing we'd rather test first. Every figure below comes from your own sales history. The reasons are ours, so argue with them.

Three changes we'd make now

  1. Store 184 · Naperville+$3,400 a month, estimated

    Raise seven core items by $0.30 to $0.50.

    This store has changed prices often enough for us to see how its customers react, and they barely do. We're 87% confident.

  2. Store 147 · Peoria+$1,200 a month, estimated

    Raise two underpriced combos by $0.40.

    Both combos sell for less than the items inside them, and combo customers here don't react much to price. 84% confident.

  3. Store 112 · RockfordCost watch

    Chicken is up 9% and your invoices haven't caught up yet.

    In about four weeks, four items drop below their margin floor. Price options are ready under your rules. Nothing moves until you say so.

One we'd test first

  1. Store 201 · Joliet+$1,900 a month, estimated

    Separate delivery prices on 12 items.

    Counter prices were copied onto the delivery menu, so the platform fee eats the margin on every order. We're 71% confident, under the 78% we need to recommend, so this runs for four weeks at this store against six similar ones. The low end of the range is below zero. That's exactly why it's a test.

1 / 2

Since the last letter

  • Measured

    Classic wings, +$0.30 at six stores: +$1,900 a month, measured against six comparison stores that kept their prices. If you agree, it goes to the rest of the chain next cycle.

  • No effect

    The weekday combo discount test at Store 233 showed nothing we could separate from noise. The discount is back, and the result is recorded like any other.

  • Rules

    All sixteen of your pricing rules passed on every change in this letter. Nothing crosses a $10 threshold, and no anchor item moves.

What we need from you

A yes or a no on the three changes, and a start date for the delivery test. The next export at the end of the month, as usual.

Talk soon,

Rodrigo

Move the price. Watch four stores disagree.

One burger, one chain, four stores. Drag the price and see what we'd do at each one. The models never look at "the chain". They look at what each store's own customers did the last time a price moved.

Drag the slider to see what changes.

Sample data. Each store's reaction to price is estimated from its own past price changes. Store D has too few to estimate, so it always gets a test first. Your step-size rule here is 8%.

A note from us

We're business students, at IE in Madrid and WashU in St. Louis, and we're building Pretaris the slow, honest way. We use sample data on the site until we have client data we're allowed to show. We test before anything gets called a result. We give you a letter you can argue with, and two people who pick up the phone.

If that sounds like your kind of pricing, send us one export. The first look is on us.
