I needed a Merchant of Record so I wouldn’t have to handle EU VAT myself. The team is what brought me to Kelviq. They answered fast every time I had a question, which matters when you can’t afford to be stuck waiting on support. And with Kelviq built for the EU, switching was an easy call.

SOFTWARE MONETIZATION

Build your product. We’ll handle the rest

One platform for payments, tax, pricing, and feature access, so you can sell globally without stitching together billing infrastructure.

Flexible pricing models

Deploy flat fee, per seat, usage, volume, credits, one-time payments, overages, and hybrid pricing.

Global payments & tax

Accept 135+ currencies and local payment methods. We handle tax nexus, VAT, and liability as your merchant of record.

Dynamic entitlements

Gate features, cap usage, and enforce credit limits. Issue license keys and deliver digital downloads.

Real-time metering

Ingest events at scale with zero latency. Track every AI token, API call, compute unit, or active user.

AGENTS, MCP AND CLI

Ask your agent to set up billing

Tell your agent what to charge. It sets up your plans and usage limits through Kelviq’s MCP server or CLI, then hands you a checkout link.

Five skills, 57 tools

Skills teach your agent how Kelviq works. Typed tools let it act on your account, from plans to checkout.

Safe by default

Start in sandbox to test, or go straight to production. Read-only tools run on their own; anything destructive asks you first.

Pricing as code

Keep plans in kelviq.config.ts. Preview with kelviq push --dry-run, then promote to production.

BILLING AND USAGE

Billing and usage in one system

Run subscriptions, usage, and one-time payments side-by-side. We keep them in sync so your invoices always match reality.

Model any pricing strategy

Mix flat fees, per-seat, and tiered usage in one plan.

Handle overages, minimum spend, and rollover credits.

Change limits and prices without touching code.

Meter usage in real-time

Track API calls, tokens, AI agents, storage, or custom units.

Update meters instantly. No processing lag.

Link every invoice line item back to a raw event log.

GLOBAL COMPLIANCE

Scale globally without the tax liability

Sell in every major global market without opening a local entity. We act as the merchant of record to shield you from global tax nexus and compliance risk.

Global payments and payouts

Accept 135+ currencies and local payment methods. We handle the FX conversion and route clean revenue to your bank.

Audit defense and risk

We assume the tax liability, manage VAT/GST filings, monitor global thresholds, and fight chargebacks on your behalf.

PRE-BUILT UI

Checkout and customer portal

Don't build billing UI. Use our hosted pages to let customers buy, upgrade, and manage invoices.

High-conversion checkout

Secure checkout for web or mobile.

Turn on cards, wallets, and local payment methods.

Enable trials, coupons, and upgrades without new code.

Self-serve customer portal

Let customers change plans and payment methods.

Show invoices, usage history, and download receipts.

Reduce support tickets with a complete self-service space.

ENTITLEMENTS & FULFILLMENT

Automate access control

Stop hard-coding permissions. We link the billing plan directly to the user state, so features unlock the moment payment succeeds.

Feature gating and limits

Gate features by plan tier (e.g., Basic vs. Pro).

Enforce limits on seats, usage, or API calls automatically.

Sync access state to your app in real-time without webhooks.

License keys and downloads

Issue license keys instantly upon payment.

Deliver secure files and private download links.

Manage validity, expirations, and renewals automatically.

BUILT FOR BUILDERS

SDKs that feel native to your stack

Use our pre-built UI for speed, or go headless for complete control. Fully typed for TypeScript and React, with native SDKs for Node and Python.

Kudos to the Kelviq team for supporting usage-based billing natively. While learning about it and implementing it for Hydrafetch, I realized how many things need to be handled correctly, especially when you’re planning for scale. For Kelviq to support this natively for all its customers, I can only imagine how well thought out the system must be.
