3 min
Sep 15, 2025
Summary:
With AI pricing models evolving fast, companies are spending too much time building custom billing logic in house.
Lark’s billing platform abstracts away billing complexity and lets you spin up your billing infrastructure in minutes. No need to store any billing related data in your system.
We manage your pricing models, credits, usage tracking, feature access, etc.
Here’s our documentation and playground. You can schedule time here or reach us at founders@uselark.io.

Problem
Defining complex usage & credit pricing models is hard
Do you offer fixed fee subscriptions with monthly usage credits (like Lovable)? Are these credits per seat (like Cursor)? You’ll have to manage these monthly credits yourself because existing providers don’t support it
Do your pricing plans have included quantities with overage charges (like Supabase)? You’ll have to manage included quantities yourself and awkwardly hammer your pricing model onto primitives that existing billing solutions offer
Do you offer dimensional pricing where pricing differs by region or other attributes (like Vercel)? Good luck defining these with existing providers :|
Managing feature access is messy
When it comes to determining whether a customer has access to your app or a specific feature, you have to keep track of a few things -
Do they have an active subscription or are in free trial?
Do they have available credits or are within the included quantity threshold?
Are they part of a blocklist? Or a special allowlist?
Most billing providers don’t offer out of the box feature access management. Or if they do, they suck.
Default end user billing experience sucks
The subscription management surfaces offered by existing billing providers are good for traditional SAAS pricing models but not usage and credit based pricing.
Your customers need realtime insights into how much usage they have accumulated, how many credits they have remaining, etc.
Customers often have to reach out to customer support for queries like refund requests or plan downgrades based on your refund and cancellation policies.
Rolling out pricing changes is a nightmare
With existing billing providers you have to run carefully coordinated migrations to rollout a price change. You update your pricing page to start showing the new prices and then gradually migrate all old subscriptions to use the new prices.
Thinking about experimenting with different pricing strategies? Engineering will quickly become a bottle neck because of all the billing integration changes required.
Solution
Flexible pricing engine
Our pricing models can support most pricing models - flat fee subscriptions, flat fee with credits, hybrid flat fee and usage based pricing, flat fee + overage, dimensional pricing, per seat credits, etc.
Powerful entitlements logic
We let you define custom rules for determining feature access. These rules are based on subscriptions status, credits, accumulated usage and included quantities, blocklists, etc.
Insightful end user billing experience
We offer embeddable and hosted surfaces that let your customers view and manage their billing information. The surfaces include AI features to handle refund and plan downgrade requests.
Zero billing management overhead
We make rolling our pricing changes simple. You can define a date for rolling out your new pricing or do it with a click in the dashboard.
We also let you experiment with different pricing strategies so you can optimize for maximum revenue and happy customers.
The above is just a small list of features we offer that makes us better than other billing platforms. There’s a lot more that we’d love to tell you about.
