Payments, tax, and billing for SaaS & AI companies
Kelviq is the complete monetization platform for SaaS, AI, and digital products. It handles payments, global tax, subscriptions, usage-based billing, digital delivery, license keys, and compliance in one place, for 3.5% + 40¢ per transaction.
For the past few months, we've been building Kelviq, and we're excited to finally share it with you.
Kelviq helps SaaS, AI, and digital products sell globally without rebuilding billing infrastructure from scratch.
It handles payments, checkout, global taxes, compliance, subscriptions, digital file delivery, license keys, usage-based billing, credits, feature access, and payouts in one place.
We built this because we kept seeing the same problem through our other product, ParityDeals.
Adding a payment gateway is easy. Building the full monetization layer around it is not.
Once you start charging for features, seats, usage, credits, API calls, or AI tokens, you usually end up building a lot of custom infrastructure:
Webhook listeners to sync payment events into your database
Subscription tables to track who has access to what
Retry logic for missed or failed events
Custom usage tracking
Feature flags tied to pricing plans
Scripts for upgrades, downgrades, prorations, and grandfathered users
Over time, pricing becomes tightly coupled with your codebase. Changing a plan, moving a feature, adding usage limits, or launching a new pricing model often requires engineering work, database changes, and a deployment.
We wanted to make all of this much simpler. With Kelviq, you can:
Get started in minutes: You don't have to handle dozens of webhooks, build a database layer to track customers, manage subscription states, or hardcode feature access. Kelviq provides a single, unified system.
Handle Global Tax & Compliance Automatically: As your Merchant of Record, Kelviq takes on the full liability for global sales tax (VAT, GST, etc.), fraud, and regulatory compliance. You can sell in 100+ countries without ever registering for a foreign tax ID.
Run any pricing model: Flat fee, usage, seats, tiers, volume, credits, pay-as-you-go, overage charges, or hybrids. Configure them in minutes.
Sell digital products with ease: Securely deliver files, e-books, or software on purchase and automatically generate license keys to validate customers.
Meter usage in real time: Count every API hit, data storage unit, or AI tokens in real time. Set soft or hard caps, pick reset cycles, send alerts, and handle overages with one call.
Control feature access: Define features per plan. Turn them on or off and check access in your app with one SDK call.
Localized pricing by country: Offer country-specific prices in 135+ currencies with VPN, proxy, and fraud protection built in. You can also set up promotions for specific countries.
Ship pricing changes without touching code: A/B test plans, roll out changes, or update pricing in real time without redeploys.
Manage the full customer lifecycle: Handle upgrades, downgrades, migrations, overrides, and grandfathering without writing custom scripts.
We are also running a special founder offer right now: 2.9% + 40¢ per transaction for your first $5K in volume. After that, just 3.5% + 40¢ per transaction.
We'd love your feedback, questions, and suggestions.
Thank you for checking out Kelviq 🙏
