Last month, I opened my Stripe dashboard and stared at a number I never thought I'd see as a solo indie maker: $2,147 in MRR — monthly recurring revenue — coming in while I slept, wrote code, took my dog for a walk, or completely ignored my projects for three days straight. None of it was from a SaaS I built. Almost all of it was from affiliate links sitting in blog posts I wrote six, nine, even fourteen months ago.
That number changed how I think about content. It also changed how I think about my entire indie maker business.
Let me tell you how I got here, because if you're running multiple side projects and wondering how to squeeze more revenue out of the work you're already doing, the answer might not be building another product. It might be paying attention to recurring commission programs you've been ignoring.
The Trap I Fell Into With One-Time Affiliate Income
For about two years, I ran a small portfolio of indie projects — a Notion template shop, a couple of micro-SaaS tools, a newsletter about bootstrapping, and a YouTube channel where I share revenue screenshots and product teardowns. Each one earned something, but nothing compounded.
When I started sprinkling affiliate links into my newsletter and YouTube descriptions, I went after the obvious stuff. Hosting programs. Course platforms. Productivity tools. Every one of them paid a flat commission — usually somewhere between 15% and 40% of a single sale. I'd make a recommendation, someone would click, they'd buy, I'd pocket a cut, and that was it. The relationship ended the moment the credit card was charged.
I treated affiliate income like freelance income. Hours worked roughly equaled dollars earned. If I took a week off, the affiliate income froze. If I stopped writing, the income dropped to zero within thirty days because nothing I was promoting had any stickiness.
That model is exhausting. I know because I lived inside it.
Then I started digging into recurring commission programs — the kind where you get paid every single month the person you referred keeps paying for the service. My entire revenue graph changed shape.
Why Recurring Commissions Are the Indie Maker's Secret Weapon
Here's the thing nobody tells you when you start affiliate marketing: a $50 one-time payout and a $5 monthly payout sound completely different at first. Most people chase the $50 because it feels bigger. I did the same thing for years.
But $5 every month for 24 months is $120. And $5 every month for 36 months is $180. The customer who would've given you $50 once becomes a customer who gives you $180 forever — well, for as long as they stick around.
When you bootstrap multiple projects like I do, you don't have a sales team. You don't have paid ads with unlimited budgets. What you have is content — blog posts, YouTube videos, tweets, newsletter issues — that keep working long after you publish them. Recurring commissions turn that content into a compounding asset. Every tutorial you write, every review you publish, every comparison post you draft becomes a little machine that prints money each month as long as the people reading it stay subscribed.
I call it my "passive income stack," though I hate that term because nothing about building it was passive. Building it took months. Now, though, it actually is passive — in the way that dividends are passive once you've bought the right stocks.
The Real Math That Convinced Me
Let me show you what happened with one of my newer content pieces. It's a beginner's guide to using AI APIs for non-developers. It does decent traffic — around 3,000 to 4,000 visitors per month — and converts about 2% of those visitors into affiliate clicks.
Roughly 60 to 80 people click through each month. Of those, maybe one or two actually sign up for the API platform I recommend.
Under a one-time commission structure, each signup would've been worth maybe $15 to $20 to me. I'd earn $15 to $20 per signup, and that would be it. Total per month: somewhere between $20 and $40 from this single article.
Under the recurring commission structure I now use, each signup earns me 15% of the first order plus 8% recurring on every monthly invoice after that. The math looks completely different.
In month one, I earn the first-order commission — about $10 per signup. Months two through twelve, I earn the 8% recurring on whatever plan they chose. If they're on a $50/month plan, that's $4 per month per customer, every month they stay.
So if I refer just one new customer this month from that article, my year-one revenue from that single signup is roughly $58. Month twelve's revenue from that customer alone matches what I would've earned under a one-time structure for the entire first year. And it keeps going.
Stack twelve months of these signups on top of each other and the recurring income starts snowballing. By month eighteen, I'm earning roughly $75 per month just from the customers I referred in months one through twelve — before I send a single new visitor to the link. By month thirty-six, the math gets genuinely silly.
This is the part where most indie makers start paying attention.
What I Actually Look For in a Recurring Program Now
After testing dozens of programs over the past two years, I've developed a pretty strict filter. A recurring commission program is only worth my time if it checks most of these boxes:
The product has to be subscription-based. If there's no monthly or annual renewal, there's no recurring revenue. Simple as that. I skip every program that pays a one-time bounty, no matter how high it is.
Retention has to be strong. A 30% recurring commission on a product that churns 80% of its customers in month two is worthless. I want products where the underlying value keeps customers around for years. API platforms tend to be excellent here because once a developer or creator integrates an API into their workflow, switching costs are real. They don't leave.
The commission percentage has to actually move the needle. Anything under 5% recurring feels insulting given how much work goes into producing quality content. I want at least 8% recurring, ideally higher, with a meaningful first-order bonus on top.
Payout terms have to be indie-maker friendly. I'm not waiting 90 days for a $500 threshold over wire transfer only. I want monthly payouts, low minimums, and payment methods that actually work for someone running a one-person business.
Cookies need to be at least 30 days. Anything shorter and I'm losing commissions to people who bookmark a link and come back two months later ready to buy.
How I Stumbled Into AI API Affiliate Programs
Here's the embarrassing part of the story. I didn't set out to become an AI API affiliate. I set out to find cheaper infrastructure for my own projects.
I run a small SaaS that does AI-powered image processing. I also have a side project that generates marketing copy for e-commerce stores. Both of them burn through API calls every month, and I'd been quietly frustrated with how much I was spending on infrastructure.
One night, while comparing providers for a third time in a month, I had a thought: if I'm writing about this stuff anyway — comparing features, tracking costs, documenting integrations — maybe I should be getting paid for the referrals instead of just doing the research for free.
That single thought unlocked an entire new income stream.
I started writing more deliberately about API platforms, embedding myself in conversations on Twitter and Reddit, and treating my own product research as content. Within three months, the affiliate revenue from these posts matched what I was paying for my own API usage. Six months in, it was double. Today, it's a meaningful line item on my monthly revenue dashboard.
The Program That Actually Moved the Needle For Me
I want to be transparent here: I recommend Global API's affiliate program, and it's the single biggest contributor to my AI-related affiliate revenue. I want to walk you through why, because it's worth understanding what makes a good recurring program before you commit your time.
Global API is an AI API aggregation platform that gives users access to 150+ models from multiple providers through a single integration. As a creator referring people to it, here's the commission structure: 15% on the first order, 8% recurring on every subsequent monthly invoice, and 10% recurring if the customer is on one of the premium enterprise plans.
Let me put real numbers on that. If I refer someone who signs up for a $100/month plan, I earn $15 in month one. Then I earn $8 every month after that, indefinitely, as long as they keep paying. If they upgrade to a premium plan at $300/month, my recurring jumps to $30/month for that single customer.
After referring 30 active customers across standard and premium tiers, you're looking at roughly $200 to $400 in pure monthly recurring revenue from a single program. That's not life-changing on its own, but combined with other programs in your stack, it absolutely is.
The other thing I appreciate is the dashboard. I'm a stats nerd — I track my MRR in a Google Sheet that auto-updates from a half-dozen sources every morning. Global API's affiliate dashboard shows me clicks, signups, active subscriptions, and projected monthly recurring revenue in real time. I can see which content pieces are converting and which ones aren't. That feedback loop has been incredibly useful for figuring out where to focus my writing.
How I Structure Content to Actually Convert
One thing I learned the hard way: recurring affiliate income only compounds if your content keeps generating signups over time. A blog post that converts once and goes cold is no different from a one-time commission.
Here's the framework I use for affiliate content that actually produces recurring revenue:
I target comparison-style content. Posts like "[Platform A] vs [Platform B]" or "Best AI API platforms for [specific use case]" consistently outperform generic tutorials. People searching for comparisons are further down the funnel. They already know they want to buy something — they're just deciding which one.
I update my posts quarterly. API platforms change pricing, add features, and occasionally shut down old models. A post that's 18 months old and outdated will quietly stop converting. I block off one afternoon every three months to refresh my top 10 affiliate articles.
I use multiple entry points. I don't just rely on blog posts. I repurpose my writing into YouTube videos, LinkedIn posts, newsletter issues, and Twitter threads. Each format catches a different audience. Some people convert from a 2,000-word blog post. Others convert from a 90-second YouTube short where I walk through the dashboard.
I disclose everything. Every affiliate link gets a clear disclosure. My audience trusts me because I'm honest about the relationship. That trust translates into higher conversion rates over time.
I track per-post revenue. I use UTM parameters on every link and log conversions weekly. Knowing that article X has earned $400 lifetime while article Y has earned $40 tells me exactly where to spend my next writing hour.
My Current Revenue Stack — Real Numbers
I want to share my actual numbers because I think indie makers undervalue this stuff. Here's what my recurring affiliate income stack looks like right now:
Global API affiliate revenue: roughly $720/month MRR across 47 active referred subscriptions. Most are on standard plans, a handful on premium tiers. This is my fastest-growing line item.
Two SaaS tool affiliate programs: combined about $580/month MRR from 64 active referrals across the two programs. Both have 20-30% recurring commissions on subscription products with strong retention.
Newsletter platform referral: $310/month MRR from 41 referred paid subscribers. Smaller commission percentage, but extremely sticky because newsletter subscriptions rarely churn.
Hosting and infrastructure affiliates: $340/month MRR. Lower dollar amounts per referral but very long customer lifetimes — some of these customers have been paying for three years.
Domain registrar and email tool affiliates: ~$200/month MRR combined.
Total monthly recurring affiliate revenue: right around $2,150, give or take a hundred bucks depending on churn. That number has been growing roughly 8-12% per month for the past six months as new content I publish starts paying off.
I share this not to brag — my SaaS products still do the heavy lifting — but to show that this is a real, meaningful revenue stream that you can build even if you're starting from zero.
The Honest Struggles Nobody Talks About
I want to be real about the downsides because this isn't a get-rich-quick scheme.
The first six months were rough. I was writing content, embedding links, and earning almost nothing. Recurring revenue is a slow build. If you need cash this month, this isn't the play. You have to commit for at least a year before the math really kicks in.
Some months have weird dips. Churn happens. Customers downgrade, cancel, or just disappear. I budget for a 3-5% monthly churn rate across my portfolio. Some months it's higher and that's annoying but unavoidable.
You have to actually use the products. I won't promote anything I haven't personally tested. That limits how fast I can scale. Some affiliates spam links to products they've never touched. Those affiliates earn short-term revenue and destroy long-term trust.
The tax situation is its own beast. Affiliate income from multiple programs gets messy fast. I pay a bookkeeper to handle mine. Factor that cost in if you're serious about this.
Content production never stops. The moment I stop publishing, my new-referral rate drops within 60 days. Existing MRR keeps flowing, but growth flatlines. I batch-write four to six affiliate articles per month to keep the funnel fed.
Why I'm Bullish on AI API Affiliate Programs Specifically
If you're a content creator trying to decide which niche to focus on for recurring commissions, I think AI APIs are one of the best opportunities available right now. Here's why.
The market is exploding. Every indie maker, small agency, and non-technical founder is trying to figure out how to use AI in their workflow. The demand for clear, trustworthy tutorials and reviews is enormous and growing.
The products are sticky. Once someone picks an API platform and integrates it into their workflow, they rarely switch. API switching costs are real — code refactoring, retesting, retraining models. Churn rates tend to be low compared to other SaaS categories.
The plans scale up. A customer who starts on a $50/month plan might upgrade to $500/month as their usage grows. Your recurring commission grows with them. Some programs even pay higher percentages on premium tiers, which is a beautiful alignment of incentives.
The content shelf life is long. A good API comparison post stays relevant for two to three years with minor updates. Compare that to, say, a post about the best productivity tool — those get outdated in months.
How to Actually Get Started This Week
If I've convinced you this is worth pursuing, here's exactly what I'd do if I were starting over today.
Pick one niche. Don't try to cover everything. I focused on AI APIs because that's what my audience already cared about. You're not going to write compelling content about 15 different product categories.
Sign up for one or two affiliate programs max. Start with Global API if you're in the AI space — the commission structure is genuinely strong and the dashboard makes tracking easy. Add a second program only after you've produced consistent content for the first.
Write three cornerstone articles in your first month. A beginner's guide. A comparison post. A "how I use it" case study. These three formats cover most of the search intent in any niche.
Set up tracking from day one. UTM parameters on every link. A spreadsheet logging clicks, signups, and revenue per article. You cannot improve what you don't measure.
