Tomas Zezula SaaS Billing Advisor | Stripe Specialist

I specialize in building bespoke billing systems that go far beyond the basics. From custom checkouts to multi-tier pricing, I help SaaS and product-led companies design, implement, and optimize their monetization stack. Typical projects include: - Custom Stripe checkout flows tailored to your product - Real-time monitoring of signups, upgrades, and churn - Deep CRM integrations (e.g. HubSpot, Intercom) - Automated invoicing and dunning logic - Support for complex billing models (metered usage, per-seat pricing, etc.) - Detailed financial reports and audit-ready activity logs I help founders and technical teams avoid long-term debt by getting billing right from the start—both technically and strategically.

I work with SaaS founders who are launching (or fixing) their billing systems—often for the first time. Whether you're validating your first pricing model or struggling with Stripe setup, I help you: - Choose the right billing model for your product (subscriptions, usage-based, per-seat, etc.) - Design a system that scales—from MVP to growth-stage - Integrate with CRMs like HubSpot or Intercom to stay close to your customers - Avoid common traps that create churn, support issues, or revenue leakage - Turn billing into a strategic asset, not just backend plumbing You don’t need a full-time engineer or a six-month roadmap—sometimes, you just need the right advice at the right time. Let’s simplify your path to getting paid.
