Flexprice

Setting up billing takes longer than it should. You pick a billing platform, map out your plans, define meters, configure entitlements, set up credit grants, wire pricing tiers together, and three days later, you're still clicking through forms.

Your engineering team burns a sprint on it. Your finance team reviews it. Someone finds a mistake, and you start over.

We built something to fix that.

Describe your pricing. Get a billing config in 60 seconds.

Prompt to Plan is an AI assistant inside Flexprice that turns a plain English description of your pricing model into a complete billing configuration.

You type something like "I have a free tier with 1,000 API calls and a pro plan at $49/month with 10,000 calls included and $0.005 per call after that."

Flexprice builds the entire setup for you: plans, prices, usage meters, entitlements, credit grants, and overage rules.

No forms or going through docs to figure out how to set up a plan. Just tell it what you charge and how you charge it.

2 ways to get started

Write it out. Open the Prompt to Plan screen, describe your pricing in the text box, and hit enter.

The AI analyzes your description, identifies every billing component, and generates the full configuration. You review it, click create, and everything lands in your product catalog ready to assign to customers.

Pick a template. If you want to model your pricing after a company that already nailed their billing structure, choose from pre-built templates. We ship with Railway, Cursor, Gemini, Apollo, and Vapi out of the box. Select one, and the AI pre-fills the prompt with that company's pricing logic. You can use it as-is or tweak it before generating.

How to try it

Here's the full walkthrough:

Step 01

Sign up at Flexprice.io by clicking "Try For Free." Fill in your credentials and you'll land on the dashboard.

Step 02

Go to Product Catalog > Plans in the left sidebar.

Step 03

Click "Create with AI". This opens the Prompt to Plan screen.

Step 04

Type your pricing model or pick a template. If you choose a template, the chat auto-fills with that pricing structure. If you're writing your own, describe your plans, including usage, overage pricing, and any credit grants you want.

Step 05

Hit enter and let it analyze. The AI breaks down your description into Flexprice billing entities: plans, prices, meters, entitlements, and credit grants.

Step 06

Review the output and click Create. Everything gets built in your product catalog. Plans, features, pricing tiers, usage tracking rules, all of it.

That's it. You go from "here's how I want to charge" to a fully configured billing system in about a minute.

What it builds under the hood

When you submit a prompt, the AI maps your pricing description to Flexprice's entity model. That means it creates actual billing objects you can inspect, edit, and attach to subscriptions:

Plans with the tiers you described (free, pro, enterprise, whatever you named them). Prices tied to each plan, whether flat-rate, per-unit, tiered, or volume-based. Usage meters that track the events you want to bill on (API calls, messages, compute minutes, seats). Entitlements that define what each plan includes. Credit grants for any prepaid usage pools or included allowances.

You get the same result as spending a day manually configuring everything through the dashboard, except you spent 60 seconds typing a sentence.

Prompt to Plan is live for all Flexprice accounts. Sign up free at Flexprice.io, no credit card required, and build your first billing configuration in under a minute.

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.
