Don't let billing become your
second product

Q: Is Flexprice a payment gateway?

No. Flexprice is not a payment gateway. We integrate with your existing payment processors (like Stripe, Razorpay, Adyen, etc.) and handle the complex pricing, credits, and usage metering layer on top of your payment flow. Think of us as the logic and control layer, not the processor.

Q: Do I have to replace my existing billing system to use Flexprice?

You don't have to rip out what you already have. Flexprice is modular and can work alongside your current stack, adding credit-based, usage-based, or hybrid pricing on top of your existing billing tool. If you prefer, you can replace only parts of your current system and migrate gradually.

Q: How do you support rapid pricing iterations?

Flexprice was built for fast experiments. Whether it's changing credit values, adjusting feature entitlements, or running A/B pricing tests, you can roll out changes in minutes, not weeks. Our API-first design means no hardcoded logic, no spreadsheet-to-code pain, and no long dev cycles for every pricing change.

Q: Why should I trust Flexprice with my billing?

Billing isn't our first rodeo. Our team has built and scaled pricing systems for high-volume SaaS products. Flexprice is open and auditable, no black boxes. We're open-source, so you can inspect and self-host if you want complete control. We maintain a public roadmap and are building with an active developer community that shapes the product alongside us. On top of that, we're SOC 2 compliant and follow enterprise-grade security practices. We're already helping early customers reduce engineering overhead while running complex pricing models and we ship fast.

Q: How are you different from other billing solutions?

Flexprice isn't just usage metering. We handle AI-specific pricing: GPU costs, API calls, credits, while fitting into your current stack. With enterprise workflows, open-source flexibility, and rapid pricing iterations, we go beyond what plan-based tools can do.
