Business Launch Checklist: What to Do in the First 90 Days

A step-by-step plan for the first three months: from validating the idea and forming a company to the first customers from ads. Save it and tick things off as you go.

The first 90 days decide whether an idea becomes a business or stays a nice pitch deck. This is the checklist we use for our clients' launches. It is split into three months, each with its own outcome.

Month 1. Foundation

Outcome: it's clear what you sell, to whom, and through which company.

  • Describe your customer and their problem in one paragraph. If you can't, it's too early to pay for a website.
  • Study 5–10 competitors: prices, offers, ads, reviews.
  • Choose a company country that fits your market and payment needs — jurisdiction selection helps here.
  • File for company formation and prepare the bank pack in parallel.
  • Fix a budget for the first three months, advertising included.

Month 2. Infrastructure

Outcome: you can take a lead and a payment.

  • Open a business account and connect payment acceptance or payment links.
  • Launch the website: a landing page with one clear offer and a form is enough to start.
  • Connect a CRM: every lead should land there automatically, with its source.
  • Set up analytics: goals, UTM tags, ad platform pixels.
  • Decide who answers customers at night and on weekends: a person or an AI receptionist.

Month 3. First sales

Outcome: first customers and a known cost per lead.

  • Launch ads on one platform: Google Ads if people already search for you, Meta Ads if demand needs to be created.
  • Test 2–3 hypotheses: different offers, audiences, creatives.
  • Review the numbers weekly: cost per lead, lead-to-sale conversion, return on ad spend.
  • Turn on retargeting for visitors who left without submitting a request.
  • Collect first reviews and cases — they lower next month's cost per lead.

Common mistakes

  1. A big website before the first customer. Six months of development without testing demand is the most expensive way to learn the offer doesn't work.
  2. Ads without analytics. If you can't see which campaign brings sales, the budget is spent blindly.
  3. Leaving the bank for last. Opening an account and acquiring can take weeks — start in parallel with formation.
  4. Leads in messengers and spreadsheets. Without a CRM some customers get lost in the very first month.

How to go faster

You can go through all three months yourself, hiring contractors one by one. Or hand the launch to one team: we run the company, account, website, CRM and ads under one plan while you focus on the product. More on the Turnkey Business Launch page.
