Opening day feels like the finish line. It is actually the moment your model meets reality. Run these twelve steps first — especially step 7, the one most owners skip.

  1. Define the concept and format. Cafe, retail, QSR, full-service? Format drives every cost number below.
  2. Size the one-time capital. Build-out, first inventory, equipment, licenses, signage, contingency. See ranges by type.
  3. Model monthly fixed cost. Rent+NNN, utilities, wages+employer tax, owner draw, other.
  4. Set your variable cost ratio. COGS % plus payment processing % — everything that scales with each sale.
  5. Find your daily minimum revenue. Fixed cost ÷ (1 − variable ratio) ÷ operating days. This is the number that decides survival.
  6. Stress-test foot traffic. Visitors × capture rate × ticket must clear that daily minimum. If not, rethink rent, price, or location.
  7. Reality-check the daily floor (do not skip). Walk the location at different hours. Is the traffic real and buyable? A pretty spreadsheet cannot save a dead corner.
  8. Negotiate effective rent, not base. Get trailing-12-month actual NNN. Model year 3 and year 5, not just year 1.
  9. Line up financing before signing. Lenders want your model, lease, and reserve plan.
  10. Estimate build-out precisely. $/sqft by concept, with a 10-20% contingency. Renovation usually overruns.
  11. Check state factors. Sales-tax registration, seller's permit, minimum wage, formation fees, industry licenses.
  12. Plan the ramp reserve. Hold 3-6 months of operating cash for the slow start.
One-page model > 40-page plan: Lenders and partners respond to numbers, not narrative. The Startup Viability Calculator turns steps 2-7 into a single printable model.
Skip step 7 and you gamble: Most "great locations" that fail simply could not clear their daily minimum revenue at the rent they agreed to pay.
