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

Global payment orchestration

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.

TAKE CONTROL OF YOUR REVENUE

Build on stable infrastructure, not platform whims.

The challenge

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?

Stay operational even if a provider changes their rules or tightens enforcement. Switch payment processors in minutes instead of months without a full rebuild or a second of downtime.

Unrivaled continuity

You own your customer data. We vault payment tokens independently so you can move processors without forcing customers to re-enter their cards, eliminating the primary cause of migration churn.

True data sovereignty

Commerce without gatekeepers

We enable your business; we don’t gate it. PaymentKit provides neutral infrastructure to ensure your revenue flows reliably, regardless of shifting platform policies.

Total flexibility with zero implementation barriers

Whether you’re a startup looking to launch in hours or an enterprise building a custom checkout experience, PaymentKit scales to your technical needs.

Launch subscriptions, invoices, checkout, and customer portals without writing a single line of code.

No code

Yes code

Integrate in under an hour with clean APIs, SDKs, and a robust sandbox so you can build and deploy without downtime.
