Book an Architecture Review

In 30 minutes we map your billing data flow, identify your infrastructure gaps, and give you a specific build-vs-buy recommendation for your ARR, event volume, and compliance posture. Cristian is an engineer. This is a technical conversation, not a sales call.

What you walk away with
1
Gap analysis
Where your current billing infrastructure fails against production-grade requirements: idempotency, audit trail, data residency, pricing flexibility, late-arrival handling.
2
Build-vs-buy recommendation
Specific to your ARR, event volume, team size, and compliance requirements — not a generic matrix. We'll tell you if self-hosting doesn't make sense for your situation.
3
Implementation scope (if a fit)
Realistic effort estimate and migration plan for your stack — event sources, data migration, parallel running period, and cutover approach.

Cristian Curteanu
Founder & Lead Engineer, ABAXUS

Built the billing infrastructure. Runs every architecture review personally. If ABAXUS isn't right for your stack, he'll say so — and explain why.

Good fit for
  • VP Eng / CTO / Technical Co-Founder
  • B2B SaaS at $5M–$100M ARR
  • Usage-based or hybrid pricing
  • Dealing with event double-counting, invoice disputes, or data residency requirements
  • Transaction fees growing faster than billing platform value

Common questions

What actually happens during the call?

In 30 minutes: we map your current event sources and billing data flow, identify specific gaps against production-grade requirements (idempotency, audit trail, compliance, pricing flexibility), and give you a clear build-vs-buy recommendation with a realistic implementation scope. No slide decks. No demos unless you want one.

Do I need to prepare anything?

It helps to know roughly: your current billing platform and monthly cost, your approximate event volume, your ARR and growth rate, and any compliance requirements (HIPAA, GDPR, SOC 2). But you don't need slides or a formal writeup — we'll ask the right questions.

What if ABAXUS isn't the right fit?

We'll tell you. Common reasons it's not a fit: team under 5 engineers, ARR under $2M, flat subscription pricing with no usage component, or you need payment processing not just billing logic. If any of those apply, we'll recommend what actually makes sense for your situation.

Is there a sales follow-up after the call?

Only if you want one. You'll get the gap analysis and recommendation on the call. If you want to move forward, we'll discuss next steps. If not, no follow-up pressure.

Can I do this asynchronously instead?

Yes — take the Billing Readiness Assessment (9 questions, 4 minutes) for an instant gap analysis, or the Savings Calculator for a 5-year TCO comparison. Both deliver results without a call. Book the architecture review when you're ready to go deeper on your specific setup.
