A launch plan turns a vague intention into dated tasks. It also forces you to decide what version one leaves out.
Days 1 to 30: build the smallest version
Define one offer for one customer. Build only what is needed to deliver it: a simple site or page, a way to take payment and a way to contact you. Resist adding features.
Days 31 to 60: pre-launch
Invite people from your validation conversations and your waitlist to try the offer. Collect feedback, fix the biggest problems and gather testimonials only from real users, with permission.
Days 61 to 90: launch and learn
Announce publicly through the channels where your customers already are. Track a few numbers weekly: visits, signups, sales and the questions people ask.
Set a measurable goal
Choose a goal you control, such as "talk to 30 prospects" or "make the first 10 sales", rather than an income figure you cannot guarantee.
Budget time as well as money
List your tools and their monthly cost, then block hours on your calendar for each task. Finish with a 30-day review: what worked, what did not, and what you will change next.
