Kelviq

Kelviq provides a unified platform for SaaS and AI companies to manage payments, tax compliance, pricing, and feature access. It acts as a merchant of record, handling global tax nexus, VAT, and liability while supporting more than 135 currencies and local payment methods. The service includes real‑time usage metering, allowing developers to track API calls, tokens, compute units, or other custom metrics with zero latency and link each invoice line item back to raw event logs.

The system supports flexible pricing models, combining flat fees, per‑seat charges, tiered usage, credits, one‑time payments, overages, and hybrid structures within a single plan. Dynamic entitlements let providers gate features, cap usage, and enforce credit limits, while subscription, usage, and one‑time billing remain synchronized to ensure invoices reflect actual consumption.

Designed for global software monetization, Kelviq consolidates checkout, tax handling, entitlement management, and revenue reporting into one infrastructure, enabling companies to sell internationally without establishing local entities or stitching together separate billing components.
