How to open a restaurant: the numbers to nail before first service
You open a restaurant on passion; you keep it open on numbers. Here are the real margins of the trade, the business plan that survives contact with reality, and the systems — specs, hygiene, training — that are a hundred times easier to set up before opening than mid-service. Plus, for later, the real test: the second location.

Definition
Opening a restaurant is three projects in one: the concept (menu, positioning, pricing), the numbers (investment, margins, break-even), and the systems (recipe specs, food safety, team training). The third is the one everyone neglects — and the one that decides whether the venue holds up when the owner isn't in the building.
The numbers the business plan has to face
Before the lease, before the build-out, put these trade realities on the table:
- Industry net margin: 3–6% full service — a plan promising 20% is lying somewhere
- Food cost: 28–35% of sales; labor with charges: 25–35% — prime cost under ~65% or nothing holds
- Break-even is calculated per service: covers × average ticket × gross margin, against the day's fixed costs
- Opening cash: the first weeks collect little and pay everything — suppliers, wages, surprises
- Every dish must be costed BEFORE it's priced — not the other way around
The classic trap isn't ignoring these numbers — it's calculating them once, in the business plan, and never updating them. Supplier prices move in month one; a dish costed at opening is fiction six months later. The system that keeps the numbers alive is worth more than the binder that stated them once.
Setting up the systems before opening, step by step
The window between signing the lease and first service is the only time you'll ever have time. Four projects to fit into it, in order.
- 1
Cost the entire menu, dish by dish
Every recipe written with its measures, yields, and cost at real supplier prices — then the selling price set against a margin target per category. With the right tools it's an afternoon's work, and it's the spine of everything else.
- 2
Set up food safety as routines, not a binder
The food-safety system is built before opening: opening and closing checks, temperature logs, traceability at receiving. Installed as daily routines from day one, these habits cost nothing; retrofitted after an inspection, they cost plenty.
- 3
Train the opening team on specs, not memory
The opening crew learns the menu from written specs and validates it with quizzes — arriving at first service knowing, not guessing. It's also the venue's life insurance: the knowledge survives the first departure.
- 4
Connect the till and read week one
Sales synced from day one, sales mix against per-dish margins from week one. The first weeks tell you which dishes carry the house — if you read them with real numbers.
The second location: the real test
A second location tests exactly one thing: did you build a business, or a very good restaurant that depends on you? Everything living in your head — recipes, standards, service steps — has to cross the street without you.
It's the same project as opening, judged harder: exact specs a new team can learn alone, hygiene routines that run without the founder, training that deploys remotely. The venues that clear this bar are the ones that documented before they needed to.
The opening kit, in days instead of months
methodus compresses the systems project — the third one, the neglected one:
The menu imported and costed in an afternoon
Upload the menu as a PDF or photo: every item becomes a draft spec with estimated costs, ready to refine. A full menu costed before opening, not weeks of typing.
Recipes dictated in 35 seconds
The chef speaks a recipe into a phone: measures, method, allergens, cost — the spec comes out complete. Documenting the opening menu stops stealing evenings.
Food safety ready on day one
Opening and closing routines scheduled, temperature logs with photo proof, label-scan traceability at receiving. The register builds itself from the first service.
An opening team that's certified
Every spec generates its quiz; the team validates the menu on their phones before first service, and the dashboard shows who holds what. The second location inherits the same kit, intact.
The know-how enters the house on day one — and the day you open the second, it crosses the street without you.
The business plan's numbers have their own guides: restaurant profit margins → and food cost percentage — nail them before you sign the lease.
Opening a restaurant FAQ
Three projects in parallel: the concept (menu, positioning, prices set on real costs), the numbers (investment, per-service break-even, opening cash), and the systems (recipe specs, food safety, team training). The third is a hundred times easier to set up before opening than mid-service — the window before first service is the only time you'll have time.
Industry ranges: 3–6% net for full service, 6–9% for quick service, more for beverage-led concepts. A business plan promising much more almost always rests on an underestimated food or labor cost — the two together need to hold under about 65% of sales.
Yes — dish by dish, at real supplier prices, BEFORE setting menu prices. A menu priced by feel discovers it's unprofitable months later, on a P&L. And the costing has to stay alive: prices move in month one, so a dish costed at opening is fiction six months later unless something updates it.
It varies enormously with location, size, and build-out — which is why the honest answer is a structure, not a number: build-out and equipment, licenses and deposits, opening inventory, and, most underestimated, working capital for the first months when the venue collects little and pays everything. Model break-even per service before committing.
When the first one produces repeatable results without you: specs a new team can learn alone, hygiene routines that run without the founder, training that deploys remotely, and margins readable per dish. The second location tests whether you built a business or a very good restaurant that depends on one person.
