How a Small Side Project Quietly Reached $4,500/Month

A side project I built is now on pace to cross $4,500/month.

What started as frustration turned into something unexpectedly real.

A while back, I experimented with selling digital resources online. Mostly PDFs and playbooks around ecommerce, paid traffic, and online growth. I had already spent a few years running a profitable Shopify business, so I wanted to package some of what I learned.

But every platform felt painful.

Some wanted monthly subscriptions before I even made a sale. Others took a huge percentage from every transaction. Then currency conversion and processing fees chipped away even more. A small sale barely felt worth it after everything got deducted.

So I built my own system.

Nothing fancy at first. Just a lightweight storefront platform connected directly to Stripe. The goal was simple:

Let creators keep most of what they earn.

Instead of charging monthly subscriptions, I structured it so transaction fees are added on top of the product price. Sellers get the amount they list. I keep a small percentage to cover infrastructure and maintain the platform.

I built the first version fast and honestly, it was rough in the beginning.

I shared it with a few people I already knew, some ecommerce communities, and a couple of private groups. The first wave of users gave me a ton of feedback, which exposed all kinds of bugs and weak spots I never noticed while building alone.

That phase ended up being one of the biggest advantages.

I started iterating aggressively.

Any time someone sent thoughtful feedback, I would usually build the fix immediately, release it only to them, and let them test it before rolling it out publicly. Most people are shocked when their feedback actually gets implemented quickly. That alone created a lot of goodwill and referrals.

Then something interesting happened.

Someone reached out cold offering growth support. Normally I ignore those messages, but I got curious and jumped on a call. His whole business was automated outreach and partnership-based distribution.

Within weeks, he brought in more users than I expected.

We worked out a rev-share arrangement tied to the customers he introduced. No complicated systems. No polished affiliate infrastructure. Just a messy setup that worked well enough to keep momentum moving.

That changed the way I think about ownership.

A smaller percentage of something growing fast is often better than trying to control 100% of something stagnant.

Right now the platform has around 500 users.

Some creators barely use it. Others are consistently generating sales every month. Watching different sellers use the same infrastructure in completely different ways has probably been the most interesting part.

The revenue is now tracking toward roughly $4,500/month.

Not “retire tomorrow” money.

But enough to prove that small utility products with the right positioning and responsiveness can become real businesses.

Two lessons mattered most:

Still early, but definitely one of the most valuable projects I’ve built so far.
