The SaaS Affiliate Strategy That Pays Monthly (Not Just Once)

I want to tell you about the side project that quietly started paying me more than my last full-time salary — and no, I'm not selling a course, I'm not running a mastermind, and I'm definitely not "leveraging AI agents" to print money in my sleep.
What I'm doing is way simpler than that. And because I believe in the whole build-in-public thing, I'm going to walk you through every ugly number, every mistake, and every small win along the way.
Let me rewind to about eight months ago.

How I Stumbled Into This (And Almost Talked Myself Out of It)

I was sitting at my kitchen table at 11 PM, staring at a spreadsheet I'd been building for three hours. On the left side was a list of AI tools and platforms I actually used in my workflow. On the right side was a list of affiliate programs each one offered.
Most of them paid once. Maybe $20 for a signup. Maybe $50 if I was lucky. You had to grind out hundreds of referrals just to see anything meaningful hit your bank account.
Then I hit a row in that spreadsheet that made me pause.
It was for Global API. The commission structure was different. Not just one-time — it had a recurring piece baked in. 15% on first orders, 8% on every renewal after that, and 10% on premium tiers.
I sat there for a long moment. A recurring cut on something people use every month? That's not affiliate marketing. That's a small piece of a SaaS business without the overhead of building the SaaS.
Here's my real numbers from that first month, because I want you to see the honest version, not the guru version:

• Referrals sent: 14
• Signups: 6
• First-order revenue generated: $1,240
• My commission: $186
• Recurring pieces: $0 (nobody had renewed yet) $186. That's the unglamorous truth. Nobody was tweeting about that number. But I kept going because I understood the math of recurring revenue, even when the math was small. # # The Mindset Shift: Why Recurring Changes Everything Most affiliate programs are built on a treadmill. You send a customer today, you get paid today. If you stop working, the income stops. It's active income dressed up as passive. The model I want to talk about is the opposite. You send a customer today, you get paid today, AND you keep getting paid as long as they stay. You build a small annuity with every signup. That's the piece that most people completely miss when they look at commission structures. They're so focused on the upfront percentage that they ignore the tail. I used to be that person. Now I look at every affiliate program and ask one question first: what do I get in month 6, month 12, month 24? For Global API, the answer was clear. With access to 150+ models through a single API, customers weren't going to sign up, try it once, and leave. These were developers and small teams building real products. Once they're integrated, they're integrated. They renew. They upgrade. The LTV is strong. # # Month Two: Doubling Down (And the Mistake That Cost Me) Month two I got more aggressive. I wrote two detailed blog posts comparing workflows. I made a couple of YouTube walkthroughs. I joined three communities where my target audience hung out. Here's what happened:
• Referrals sent: 31
• Signups: 11
• First-order revenue generated: $2,890
• My commission: $433.50
• Recurring from month one customers: $74.40 (those first 6 had renewed) Total: $507.90 Better. But here's where I made the mistake. I got greedy. I saw a competitor's affiliate page offering a one-time $200 bounty per signup for a different product, and I almost pivoted my entire strategy toward that. Higher upfront, right? I ran the numbers. To match my month two recurring income, I'd have needed 2.5 signups at $200 each. That sounds achievable. But here's the thing — those signups would be one-and-done. No tail. I'd be on that treadmill forever. I stuck with the recurring model. I'm glad I did. # # The Hardest Lesson: You Have To Pick a Lane Around month three, I had a minor breakdown. My income was growing, but it was chaotic. I was trying to sell to everyone. Indie devs. Agencies. Content creators. E-commerce stores. Anyone with a pulse who might want AI capabilities. The problem? I had no depth anywhere. My content was generic. My landing pages said nothing specific to anyone. I was the textbook definition of "scattershot." This is the part of build-in-public that doesn't make it to Twitter threads. The unglamorous middle where you realize the strategy is broken and you have to admit it publicly. I sat down and made a decision. I was going to niche down to indie developers building SaaS products who wanted to add AI features without becoming AI infrastructure experts. That was my people. That was the audience I actually understood because I was one of them. Within six weeks of refocusing, my conversion rate on referred signups nearly doubled. Here's month four:
• Referrals sent: 38
• Signups: 19
• First-order revenue generated: $4,120
• My commission: $618
• Recurring from previous months: $214.80 Total: $832.80 Same amount of effort, better targeting, better outcome. That's the lesson I keep coming back to. # # What "Build in Public" Actually Means For an Affiliate Business People hear "build in public" and they think you have to livestream every line of code or post your Stripe dashboard every Friday. That's not quite it. To me, build in public means three things:
• Sharing what you're trying, including the stuff that flops. I posted about that $186 first month. I posted about the scattershot mistake. I don't edit out the bad weeks.
• Documenting the systems, not just the wins. When I figured out that a Notion tracker for my referrals was making me faster, I shared the template. When I built a simple email sequence for new signups, I shared that too. The point isn't to gatekeep — the point is to be useful.
• Treating your audience like peers, not prospects. I never pitch hard. I share what I'm doing, why it's working, and what I'm learning. Sometimes people click my link. Sometimes they don't. The ones who do tend to stick around because they came in informed. The compounding effect is real. Every month I post an income breakdown, more people find me, more of them trust me, more of them check out the things I'm using. It's slow at first. Then it's not. # # Month Six: Where The Recurring Math Started To Hit This is the part I wish someone had shown me on day one, because I almost quit in month two. Here's my month six breakdown:
• New referrals sent: 42
• New signups: 22
• First-order revenue generated: $5,610
• My commission: $841.50
• Recurring from months 1–5: $687.20 Total: $1,528.70 That recurring line — $687.20 from people who signed up in previous months — that's the number that changed my brain. I didn't lift a finger to earn it. Those customers were already integrated into their products. They were already paying their monthly bill. My slice just kept arriving. This is what people mean when they talk about passive income being a function of time, not effort. The effort happens upfront. The income keeps coming. # # The Setup That Actually Works For Me Let me walk you through how I run this thing, because I get asked about it constantly. My main content hub is a blog where I write detailed tutorials for indie devs integrating AI into their SaaS products. Every post links to Global API where appropriate, with my affiliate link. Not shoved in. Just naturally, because it's genuinely the platform I use and recommend. My secondary channel is a weekly newsletter where I share one thing I learned that week, one tool I'm using, and one revenue update. That newsletter has a 42% open rate because the audience knows they're going to get honest numbers. My community presence is in three places: a Discord for SaaS founders, a subreddit for indie hackers, and a small Twitter following I've been growing. I show up, I help people, I mention what I use when it's relevant. That's it. My tracking is dead simple. A spreadsheet with referral source, signup date, plan level, and monthly recurring commission. I update it every Sunday. Takes ten minutes. Transparency means nothing if your numbers aren't accurate. That's the whole operation. No fancy software. No automation funnels. No paid ads. Just content, community, and a recurring affiliate structure that pays me month after month. # # Why Global API Specifically (The Honest Version) I've tried other affiliate programs. I'm not going to name them, but I'll tell you why they didn't stick. Most affiliate programs in this space have one or more of these problems:
• One-time payouts only
• Tiny commissions that don't scale
• Cookie windows so short you lose attribution
• Products that customers churn off quickly Global API's structure sidesteps all of that for me. The 15% on first orders is competitive upfront. The 8% recurring on renewals is what makes it a real business. And the 10% on premium tiers means when a customer upgrades (which happens when their usage grows, which happens when their business grows), I get paid more. Plus, the platform gives access to 150+ models through a single API. That's the pitch that closes customers for me. When I tell an indie dev they don't have to juggle five different API keys and five different billing relationships, that resonates. It removes a real pain point, which makes the sale honest, which makes me feel good about the recommendation. # # Month Eight: Where I Am Right Now Current monthly numbers, as of last week:
• Recurring from all previous months: $1,140
• New signups this month: 18
• New commission: $612
• Total projected this month: ~$1,750 That's not life-changing money for everyone, but for me — working maybe 6–8 hours a week on this — it has completely changed how I think about side projects. It's also replaced roughly 70% of what I used to earn at my 9-to-5. I'm not saying that to brag. I'm saying it because I want you to see the trajectory. Month one was $186. Month eight is on track for $1,750. That's the power of recurring + compounding. And the thing is, I haven't even touched the premium tier push yet. Most of my referrals are on standard plans. When I start focusing more on the higher-tier customers, that 10% difference is going to move the needle meaningfully. # # What I'd Tell Someone Starting Today If you're sitting where I was eight months ago, staring at your own spreadsheet of options, here's what I'd tell you: Pick the model with the tail. Recurring income is the only kind of side income that scales without scaling your effort proportionally. Every other model just gives you a bigger treadmill. Niche down faster than you think you need to. I waited three months. I should have waited three weeks. Specificity converts. Generic doesn't. Show up consistently, even when the numbers are small. Month one was $186. I almost quit. I didn't. That decision is now worth over a thousand dollars a month to me. Share your real numbers. Not the rounded-up, vanity version. The actual cents. That's what builds trust. That's what separates you from the thousands of other people recommending the same products. Track everything. You can't improve what you don't measure. A simple spreadsheet changes the game. # # Should You Join The Global API Affiliate Program? Here's my genuine take, because I don't do fake recommendations. If you're a developer, a SaaS founder, a content creator in the AI space, or anyone with an audience that overlaps with people who need AI capabilities for their products — yes. You should look at this seriously. The structure is built for people who want a real business, not a quick hustle. 15% on first orders gives you a solid upfront return. 8% recurring on renewals turns every signup into a small annuity. 10% on premium tiers means your income grows as your referrals' usage grows. And you're recommending a platform with 150+ models accessible through a single API, which is an easy product to genuinely stand behind. If you want to check it out, here's the link to the affiliate program: https://global-apis.com/affiliate I'm not going to dress this up with some fake urgency or a "limited time bonus." The program is what it is. The numbers are the numbers. I've shown you mine. Now go see if it fits yours. That's the whole pitch. Build something. Share the journey. Let the compounding do its thing.
