Billing built for AI businesses
Unify billing, analytics, and payments to scale your revenue
Most billing platforms struggle with the “credit-heavy” nature of AI. PaymentKit is built to handle complex usage logic and global routing at the speed of your API.
Monetize usage
Adaptive usage logic
Launch seat-based, tiered, or credit-based models in minutes. Identify high-value features and set usage limits or overage triggers with clicks, not code.
Global payment orchestration
Automatically route global subscribers to the processor with the highest acceptance rates and lowest fees.
Quote-to-cash agility
Seamlessly add a sales-led motion. Give your team the power to negotiate custom enterprise contracts with flexible credits and bulk-usage discounts.
Secure recurring revenue
Customer notifications
Send automated, branded alerts to keep subscribers informed and prompt card updates before they churn.

Why PaymentKit
Build on stable infrastructure, not platform whims.
A payment processor’s policy shouldn’t dictate your revenue. One unilateral decision can shut down your business overnight. How do you stay in control?
Subscriptions outlive your MIDs
When a MID dies, subscribers keep billing on a new one with no card re-entry: tokens are vaulted above the processor, so the next renewal simply lands on a healthy account.
True data sovereignty
You own your customer data. We vault payment tokens independently, so you can move processors without forcing customers to re-enter cards, the primary cause of migration churn.
Commerce without gatekeepers
We enable your business; we don't gate it. PaymentKit provides neutral infrastructure so revenue flows reliably regardless of shifting platform policies.
