Stripe Billing

Predictable Revenue.

Most companies using Stripe are losing 3–8% of revenue without realizing it. I engineer the systems that find the leaks and fix them.

“The question is — how much revenue are you leaking?”

For SaaS Platforms and business invoicing

You don’t need subscriptions.
You need predictable revenue.

“Right now, your billing system is either going to scale with you… or it’s going to become the thing that breaks you.”

For Marketplaces

Connect is where platforms
quietly destroy themselves.

“You’re building a financial system, not a feature. liability exposure and payout delays aren't bugs—they're existential risks.”

Risk Mitigation

Revenue isn’t revenue until it’s safe.

I don’t just build billing systems; I build financial fortresses. Security isn't a feature—it's the foundation of your revenue architecture.

“One major dispute can freeze your Stripe account. I build the systems that prevent the freeze.”

The Conversation Aligned

“That’s expensive.”

Compared to losing 5% of revenue annually? If I recover just 2% of your ARR, that would pay for the service investment - this is purely focused on ROI.

“Can we just pay hourly?”

Hourly billing rewards me for being slow. Performance billing rewards me for increasing your revenue.

“Another developer quoted us less.”

It's likely they're just installing Stripe. My solution is engineering your revenue system.

The Diagnosis

Stripe isn’t your payment processor.
It’s your revenue engine.

Do you already have a Stripe system in place?
