Kelviq

Kelviq takes on the legal liability for global sales tax, fraud, and regulatory compliance as your seller of record. In practice that means you can sell in over 100 countries without registering for a foreign tax ID or managing VAT filings yourself. Sound like a lot of paperwork? Yes, and Kelviq handles it. The platform monitors global thresholds and fights chargebacks on your behalf, which is the part most small teams can't staff internally.

You can track every API call, LLM token, compute unit, or active user as it happens. Metering events are ingested with no processing lag, and each invoice line item links back to a raw event log so billing disputes are easy to trace. Soft and hard caps, reset cycles, and usage alerts let you react before a customer blows through a budget. That last part matters.

Flat fee, per seat, usage, volume, credits, one-time payments, overages, and hybrids all run on the same system. You can mix a flat fee with tiered usage in a single plan, and change limits or prices without touching code. No redeploys. No engineering tickets. A/B testing pricing and rolling out changes in real time becomes a product decision, not a sprint.

Kelviq links the billing plan directly to user state, so features switch on the instant payment succeeds. You gate features by plan tier, enforce seat or API limits automatically, and sync access state to your app in real time without webhooks. For teams tired of scattering feature flags across a codebase, this centralizes the logic.

The platform accepts 135+ currencies and local payment methods, handles FX conversion, and routes clean revenue to your bank. International cards add 1.5%. Recurring charges add 0.7%. Those stack onto the base rate. Payouts run on a T+7 rolling basis, with custom schedules negotiable for established enterprise partners.

You don't have to build billing UI. Hosted pages handle checkout, upgrades, coupons, and trials on web or mobile, while a self-serve portal lets customers change plans, update payment methods, view invoices and usage history, and download receipts. Fewer tickets. Less back-and-forth. That removes a long list of support requests that otherwise land on your team.

License keys are issued instantly on payment, and secure files or private download links are delivered automatically. Validity, expirations, and renewals are managed for you, which suits software vendors, course creators, and anyone selling downloadable assets.

You can use pre-built UI for speed or go headless for full control, with typed SDKs and a documented REST API. Kelviq's design also avoids the usual webhook sprawl and subscription tables, letting you query customer and entitlement state directly from the API as your source of truth.
