    Selling & Closing Your First Customers

    Turn conversations into paying customers

    Estimated time: 8-10 hours
    Semester 1/Phase 4 · Launch & Get Paid/Week 14

    Lesson

    This week turns interest into honest sales conversations. You will diagnose the customer's situation, demonstrate the relevant value, handle concerns, and ask for a clear decision.

    What you will be able to do
    • Run a structured discovery call
    • Demonstrate the product around the buyer's problem
    • Respond to objections without pressure
    • Follow up with clear actions and dates

    Discover before you demonstrate

    Start by understanding the current process, problem, impact, priority, decision process, and timing. If the problem is not important or the product is not a fit, say so. A good sale creates a useful decision, not merely a yes.

    A demo should tell a customer story

    Show the shortest path from the buyer's current problem to a useful result. Use their language and focus on the features that matter to the stated need. Prepare test data and a backup recording so a technical issue does not end the conversation.

    Handle objections with curiosity

    An objection may reveal missing information, low trust, poor timing, or weak fit. Acknowledge it, ask a question, answer with evidence, and check whether the concern is resolved. Do not invent urgency or make promises the product cannot keep.

    Close with clarity

    Summarise the agreed problem, value, offer, price, and next step. Ask directly whether the buyer wants to proceed. Send a short follow up with responsibilities and dates. Keep the relationship respectful even when the answer is no.

    Set up a legal company to collect payments

    Once you have validated your product and have real traction, such as buyers ready to pay, it is time to form a legal entity. You do not need to do this on day one. Founders from almost any country can open a US company online for a few hundred dollars with services such as Stripe Atlas or Firstbase. An LLC is simpler and suits most solo founders who want to keep the profits. A Delaware C Corp is the better choice if you plan to raise venture capital. These services help you get your company documents, a registered agent, and an EIN (US tax number). Next, open a US business bank account that accepts non-residents, such as Mercury, and connect it to Stripe so customer payments land in your company account. This gives you a fully legal company that can invoice customers and accept card payments worldwide. Check your home country's tax rules and speak to an accountant before filing.

    Video of the week

    Why it fits: Covers founder-led sales, prospect lists, outreach messages, demonstrations, sales funnels, charging early customers and onboarding.

    Video activity

    Build a list of 25 prospects, send five personalized messages and invite interested prospects to a short demonstration.

    The video supports the lesson above — it doesn't replace it.

    Guided activities

    1. 1Role play a 20 minute sales call
    2. 2Create a five minute demo path
    3. 3Build an objection log from real conversations
    Prompt you can adapt
    Role play a realistic buyer for this product. Use the customer profile and objections below. Do not make the conversation easy. After the role play, score my discovery, listening, relevance, evidence, objection handling, and close. Quote specific moments and suggest a better question or response for each weakness.

    Week 14 · Case study

    GenAIPI wins a customer days after the first build

    Source note: Documented customer story published by Replit. Costs, timeline, and contract value are reported by the platform. The student-sized version below is an illustrative exercise, not part of the reported case.

    Jon Cheney had previously received a $105,000 quotation to build an application he had been considering for years. Without a coding background, he later used Replit to create GenAIPI’s website, administrative tools, and product over a weekend for under $400.

    According to Replit’s customer story, he secured a first customer worth $15,000 within five days. The transferable lesson is not to expect a large contract after every weekend build. Cheney converted an existing understanding of business needs into a working demonstration and a specific offer.

    Student-sized version

    Identify five prospective customers with the same narrow problem. Show them a working workflow, ask questions about their current process, and offer a small paid pilot with clearly defined limits.

    Discussion question

    What evidence should a customer see before agreeing to a paid pilot?

    Assignment

    Run ten sales conversations and aim to close the first paying customer. Submit anonymised call notes, funnel results, common objections, follow up examples, and a reflection. If no sale closes, identify the strongest evidence about fit, trust, timing, or price.
