Chapter 13 — Digital Products, Courses, and Affiliate Income

Chapter 13 — Digital Products, Courses, and Affiliate Income

This is the top rung of the ladder: create something once, sell it hundreds or thousands of times, with almost no cost per sale. A $49 resume template that sells 200 copies earns $9,800; a $99 course with 300 students earns $29,700. No inventory, no shipping, no employees. The math is seductive — and real. But the internet is full of people selling the dream and skipping the fine print; this chapter gives you both.

The “Create Once, Sell Many Times” Idea

A physical product costs money every time you sell one — materials, shipping, handling. A digital product costs money once, when you make it. A $39 ebook sold through your own site (about 3% in processing, so you keep ~$37.83 per sale) earns ~$1,890 at 50 sales, ~$7,565 at 200, and ~$37,830 at 1,000. Nobody sells 1,000 copies by accident — but even 50 sales of a genuinely useful product beats most side hustles for the hours invested, if you can find the buyers. That “if” is the entire game.

Digital Products: What Sells

The ones that sell solve a specific, painful problem for a specific person. Templates and spreadsheets: budget planners, invoice templates — a cleaning-service owner would happily pay $29 for a ready-made client contract and pricing calculator instead of building one from scratch. Ebooks and guides: short, practical, specific beats long and general (“The Food Truck Permit Guide for Massachusetts” outsells “How to Start a Business”). Planners and printables: often sold on Etsy for $5–$15, making money on volume. Design assets (stock photos, fonts) — one good font family can earn for years. Software: the highest ceiling and highest skill requirement — a $9/month tool with 500 subscribers is $4,500/month in recurring revenue. What sells, in one sentence: a specific solution to a specific problem, for a specific person, at a price that feels like a no-brainer compared to the problem.

Validate Before You Build

The pre-sell: describe the product on a simple page and ask people to buy before it exists (be transparent: “releases March 1”) — if 20 strangers pay $29, you have proof; if nobody pays, you have saved yourself 100 hours. The survey with teeth: do not ask “would you buy this?” — ask “what is the hardest part of doing your business taxes?” and build the answer to the most common reply. The minimum version: sell the ugly first draft — a freelance translator could sell a $19 PDF of “50 email templates for client work” before ever filming a course.

Rule of thumb: if you cannot find 10 people who want it before it exists, you will not find 200 after.

Online Courses: Teach What You Can Actually Teach

Courses command the highest prices in the digital world — $49–$299 is normal — because people pay for transformation, not information. Teach something you have actually done, for people a few steps behind you: a bookkeeper with five years of experience teaching “Bookkeeping for Freelancers” is credible; a beginner teaching “How to Get Rich” is not.

Simple production is enough to start. A smartphone, decent light, and a quiet room produce perfectly acceptable video; what kills courses is rambling, disorganized content. Plan every lesson on paper first: one idea per lesson, each under 10 minutes.

Platforms, in plain terms: on Teachable / Thinkific you bring the students and keep most of the money (minus ~5–10% in fees) — full control, but you do the marketing. Udemy brings millions of students but discounts aggressively (your $99 course routinely sells for $14.99) and you keep roughly 37–50% — still $12,000 for 2,000 sales at $15 with a 40% share. Skillshare pays per minute watched: pennies per student unless you scale.

Honest expectation: a first course from a beginner with no audience typically earns $200–$2,000 in its first year — not failure, but the tuition you pay while building the audience that makes course #2 or #3 take off.

Affiliate Income Done Right

Affiliate income means recommending products and earning a commission when people buy through your link — rates run 3–50% (Amazon pays around 3–4%, software companies often 20–50%). Example: you recommend the invoicing tool you actually use at 30% recurring commission on a $20/month plan — that is $6/month per signup, so 100 referrals over a year becomes $600/month on autopilot, for a product you genuinely like.

The honest way — the only way that lasts: only recommend what you would use yourself, because one bad rec burns trust that took a year to build. And disclose it, every time — federal law requires it (the FTC), and fines are real. Plain language near the link works: “I earn a commission if you buy through this link — it costs you nothing extra.” Affiliates work best inside content people already trust: the pattern is always the same — help first, recommend second. A post titled “The 3 Invoicing Tools I Tested (and the One I Kept)” earns affiliate income for years; a page that just screams “BUY THIS” earns nothing.

Realistic expectations: affiliate income starts embarrassingly slow — $10–$50/month for the first 6 months is normal — then compounds, because each piece of content keeps working while you make the next one. Earners at $2,000–$10,000/month usually spent 1–3 years building the audience first.

The Slow Start Is the Price of Admission

Every model in this chapter shares one trait: the beginning is slow and the rewards compound. The winners here almost always built their audience on a lower rung — freelancing clients who became course students, a service business’s email list that became ebook buyers. Start where you are, build the audience while a lower rung pays the bills, and treat the first year as building, not earning. The ones who quit treated month two as the verdict.

Key takeaways

• Digital products have near-zero cost per sale: a $49 template × 200 sales ≈ $9,800 — but finding the buyers is the entire game.
• What sells: specific solutions to specific problems for specific people; validate with pre-sales, waitlists, or a minimum version before building.
• Courses pay $49–$299; teach what you have actually done, film with just a phone, and know the platform trade-offs (Teachable = control, Udemy = their traffic but ~37–50% share).
• Affiliate income (3–50%) works only the honest way: recommend only what you would buy, and disclose every commission — the FTC requires it, and fines are real.
• Expect a slow start: $10–$50/month for months is normal; income compounds over 1–3 years as audience and content accumulate.
• Build the audience on a lower ladder rung while it pays your bills — then create once and sell many times.
