Flexprice Manifesto: Why Billing Needs a Reset
Flexprice is redefining billing for AI and agentic companies with an open-source, full-stack monetization platform—built for usage-based and outcome-based pricing models, complete flexibility, and developer-first control.



For years, billing was easy because it was seat-based. You charged a fixed price per user or a flat yearly fee, and that covered everything.
Pricing changes were rare, maybe once a year, and it all worked fine.
But that’s not the case anymore.
The Reality of 2025
AI has changed the rules.
Pricing is no longer about “users.” It’s about GPU hours, tokens, API calls, and constantly shifting usage patterns.
The needs of AI and agentic companies are evolving at a fast pace. Almost 85% of these companies have shifted to usage-based pricing models and are now gradually moving towards outcome-based pricing.
But the conventional billing tools aren’t able to cope-up with the speed at which the pricing is evolving
In the end, your engineers are forced to write custom logic over these billing systems just to make them work.
This is why we’re building Flexprice and here’s our approach.
1. Open Source
We believe that pricing logic is unique to every company, which is why we give your developers the flexibility to create any pricing logic they want. You have complete freedom to connect it to your existing tools, integrate with any data warehouse, and use any payment gateway.
There is no vendor lock-in. Flexprice is free to self-host so you own the complete stack. For teams that prefer a managed cloud version, we charge a fair, fixed price, no hidden fees, no revenue share.
And because flexibility should also mean transparency, we make it easy for you to see and shape what we’re building. As developers, we hate sitting on sales calls or waiting for days to get answers to simple queries.
That’s why we have a public roadmap where you can track our progress, add tickets to prioritize features, and see when they’re picked up. We also have a Slack community where you get responses from our team within minutes.
2. The Entire Monetization Stack
We don’t think of pricing as just usage-based metering. As you scale, your stack needs much more. It includes:
Usage metering
Customer-facing elements like pricing widgets, usage dashboards, and trial banners
Pricing workflows like upgrades, downgrades, and discount
Pricing engine that includes plans, add ons, recurring charges and credits
Most billing tools cover only one or two of these areas, forcing your developers to custom-build the rest. We don’t want you piecing together a system like Lego blocks, that’s why we’ve built the entire monetization stack for you.
3. Built So Your Engineers Focus on Building the Product
With Flexprice, everything is built in: usage metering, credit systems, pricing workflows, and enterprise contracts. No more patching or duct-taping logic around a rigid platform.
Your engineers can finally focus on building the product, not rebuilding billing logic every time your pricing evolves
This Is the Future of Billing
Billing isn’t a back-office chore. It’s the growth engine you can’t afford to ignore.
The companies defining the next decade Snowflake, Datadog, OpenAI didn’t wait for pricing to catch up with them. They built monetization that scaled with every new feature, every customer segment, every spike in usage.
That’s what Flexprice gives you.
Not a tool. Not a workaround.
A foundation for monetization open, programmable, and built for the velocity of AI and agentic companies.
If pricing is your growth lever, Flexprice is the stack that lets you pull it, fast, clean, and without breaking things.
The next generation of monetization infrastructure won’t be built behind closed doors. It will be built by those who need it most founders, engineers, and growth teams who want complete control.
If you’re ready to take ownership of your monetization, build with us.
