SaaS billing platforms charge 0.5–0.8% of revenue — a cost that scales with your ARR without adding value. ABAXUS is a flat annual license. At $10M ARR, the savings pay for 4–5 years of ABAXUS.
SaaS billing fee estimate: 0.7% of ARR (typical Metronome/Orb/Stripe Billing blended rate)

ABAXUS is in active development. The first 10 teams who deploy in production and give monthly feedback lock in a 65% lifetime discount on license — before GA pricing applies. The goal is customers we can build with, not just for.
We pick early adopters based on fit, not first-come-first-served. A qualifying architecture review confirms the technical fit and ensures ABAXUS actually solves your specific problem before you commit.

No. There are no overage charges on any tier. If you consistently exceed your tier's event limit, we'll talk about moving to the next tier — but you won't get a surprise invoice for overages. Billing infrastructure that penalizes you for growth is the exact problem ABAXUS exists to solve.
No. The price you pay on signup is your price. We don't do annual price increases. If GA pricing changes for new customers, your price stays where it is. Early adopter pricing is explicitly guaranteed in writing for the lifetime of your license.
A billed customer is any customer entity (customer_id) that has at least one active subscription in ABAXUS in a given month. Test customers and internal environments don't count against the limit.
On Growth: guided Kubernetes/Docker deployment, event schema review, pricing model configuration, and SDK integration support — all included for the first 90 days with no hourly cap. We want your integration to succeed. On Scale, this extends through the contract term with a dedicated solutions engineer.
Yes, on Growth and Scale tiers. Migration includes: parallel run strategy (running ABAXUS alongside your current platform to validate parity before cutover), event schema mapping, historical data migration approach, and cutover planning. We've done this migration from Stripe Billing, Metronome, and custom built systems.
Growth and Scale customers get access to a shared feature request queue with visibility into current roadmap priorities. Your votes affect prioritization. Scale customers get fast-tracked review on their requests — typically reviewed within 2 weeks. Early adopters influence the roadmap directly via monthly feedback calls.
We'll tell you on the call and recommend what makes sense for your situation. Common reasons ABAXUS isn't a fit: team under 5 engineers, ARR under $2M, simple flat subscription pricing with no usage component, or you need payment processing (Stripe Checkout, card vaulting) rather than just billing logic. There's no pressure to proceed if the fit isn't there.
Book an architecture review. On the call, we confirm the technical fit — that ABAXUS actually solves your specific billing infrastructure problem and that your stack is a good match for a production deployment. If both sides agree, we proceed with early adopter terms. The 65% discount applies from day one, and you're locked in for life.
In 30 minutes we size your situation, confirm the fit, and — if you qualify — walk you through early adopter pricing. No obligation.
