Kelviq is the all-in-one revenue infrastructure platform built from the ground up for SaaS and AI companies. As a Merchant of Record, Kelviq takes full liability for global sales tax (VAT, GST), fraud, and regulatory compliance — letting AI startups sell in 100+ countries without ever registering for a foreign tax ID. It supports subscriptions, usage-based billing, feature entitlements, and one-time purchases through a single API. The AI-specific angle is real-time metering: Kelviq can track every token, API call, compute unit, or active user with zero reported latency. This is critical for AI products where costs spike unpredictably and customers need granular visibility into what they're being charged for. Pricing is 2.9% + 40¢ per transaction (up to $5K/month volume) or 3.5% + 40¢ thereafter, with no monthly fees — competitive with Stripe + a separate tax tool. Built by the team behind ParityDeals (a price localization tool with proven market fit), Kelviq launched to #1 on Product Hunt today with 430 upvotes. The founders' experience running a SaaS business internationally gives them genuine insight into the pain points they're solving.
Reviewer scorecard
“Free tier with no restrictions is remarkable. Completion quality rivals Copilot for most languages.”
“Token-level metering with real-time entitlement enforcement in one API is the infrastructure I've been duct-taping together with Stripe + Lago + TaxJar for years. Kelviq collapsing that stack is worth serious evaluation, especially for early-stage AI products.”
“Hard to argue with free. The enterprise features and Windsurf IDE show they have a real business model beyond the free tier.”
“Merchant of Record is a trust-intensive category. If Kelviq has a billing outage, your revenue stops. I'd want to see their uptime track record, enterprise SLAs, and how disputes are handled before migrating a live AI product off Stripe.”
“Giving away code completion to win IDE market share with Windsurf is a smart long-term play.”
“As AI agent economies mature, usage-based billing at token granularity will be table stakes for monetization infrastructure. Kelviq is positioning at exactly the right layer — the picks-and-shovels for the agentic economy.”
“The pre-built hosted checkout and customer portal mean creators and solopreneurs launching AI tools don't need a backend engineer to handle billing. That's a genuine unlock for indie AI product launches.”
