Flexprice Vs. Orb

Orb is a solid billing engine for usage-based pricing. But it's closed source, locked to Stripe, and is expensive. Flexprice gives you the same depth, open source, multi-gateway, and built for teams from self-serve to enterprise.

If billing doesn't work, we don't make money. Flexprice lets us focus on the core business instead of building billing as a second product.

Introduction
SaaS billing started with subscriptions, and the first wave of usage-based billing tools like Orb were built to solve that shift. Orb does this well. It has a clean API, solid credit infrastructure, and strong enterprise contract features.

Orb works best for high-volume API companies already on Stripe that need flexible usage-based billing with enterprise hierarchy support.

And you should stick with Orb if:

  • You're already using Stripe as your only payment gateway and don't plan to serve customers outside Stripe-supported regions.
  • You have dedicated engineering resources to handle implementation and don't need to self-host or inspect the billing engine.
  • You're comfortable with an expensive starting cost and don't need a free or open-source tier to iterate on pricing early.
  • You don't need your billing system to integrate natively with multiple CRMs like HubSpot, Zoho, or Pipedrive.
