Hi Product Hunt 👋

I'm Sachin, co-founder of Kelviq.

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 🙏

 love the product.. all the best Sachin.. 🚀

 Thanks Ayush!

Hunter

 Many congratulations Sachin on launching Kelviq on Product Hunt! :)

How I met the maker?

I first discovered Sachin’s work through his earlier products and have been following his journey since, we had re-connected last year via our mutual friend during the launch. When he started building Kelviq it instantly caught my eye.

What is Kelviq?

Kelviq is a complete monetization platform for SaaS, AI, and digital products that bundles payments, checkout, global taxes, compliance, subscriptions, usage-based billing, digital delivery, license keys, credits, and feature access into one system.

Instead of stitching together a payment gateway, webhooks, custom billing logic, and tax tooling, you plug into Kelviq and get a unified platform plus a Merchant of Record that handles global tax and compliance for you.

Why I endorse Kelviq?

I endorse Kelviq because it lets founders launch serious billing in days instead of months and keep iterating on pricing without constant engineering work.

Support for flat, seat-based, usage-based, credit-based, and hybrid models along with real-time metering (API calls, AI tokens, etc.) and localized pricing in 135+ currencies makes it a powerful fit for modern SaaS and AI products that want to scale globally.

Give it a spin! :)

Maker

   Thanks so much, Rohan!


Really grateful for all your support, and especially for hunting Kelviq today 🙏

 First, congratulations on the launch!

This is really interesting. I especially like that you’re addressing the AI side of SaaS products because AI introduces a completely different layer of pricing and billing complexity that traditional SaaS platforms usually don’t have to deal with.

Curious how Kelviq handles AI token pricing specifically — do you interface directly with third-party model/vendor pricing and track changes over time, or is pricing logic configured manually by the customer? For example, if Anthropic or OpenAI changes pricing for a model, how does that flow through the system?

And again congratulations!

Maker

 Thanks, Blaize! Really appreciate it.

Currently, we don't track model pricing directly. Customers can configure their own pricing logic, usage units, credits, and limits inside Kelviq, but model/vendor pricing changes still need to be tracked manually for now.

But this is something we have in the pipeline.

 This is critical for the unbundling of SaaS wave that is just beginning. Do you have an MPP / x402 so that agents can choose Kelviq? Given it's already usage-based, it seems pretty natural.

Would a dev / agent choose Kelviq over Stripe? Seems like you do the full payment processing

Congratulations on the launch!

Maker

 Thanks, Riya!

Congrats on the launch 🙌

Does Kelviq handle reverse-charge VAT for B2B sales within the EU automatically (valid VAT ID = no tax charged)?

Maker

 Yes Francesco, we do handle reverse-charge VAT for B2B sales. If the customer provides a valid VAT ID, no VAT is charged.

Whether the VAT should be deducted from the gross amount or handled separately can also be configured at the settings level.

 that’s exactly the answer I was hoping for =)

Follow-up question, how does Kelviq handle fraud protection and chargeback disputes? Specifically curious about the AI/SaaS side where you sometimes see stolen-card signups burning through trial credits before the chargeback hits.

Also, full transparency, I’m Francesco, founder of VisibAI (), we’re an AI visibility auditing platform launching publicly in June ahead of WE Make Future 2026 in Bologna. I’m actively evaluating MoR providers right now, so genuinely interested in learning more.

Would love a demo if your team is open to it 🙏

Maker

   Thanks, Francesco! VisibAI sounds really interesting.

For payments and fraud protection, Kelviq uses Stripe under the hood, including Stripe's fraud and risk systems. On top of that, since Kelviq acts as the Merchant of Record, we handle disputes and chargebacks on your behalf.

And of course, happy to give you a demo and walk you through the product.

 Awesome! Looking forward to it

Big fan of your work Sachin, congrats on the launch!

Maker

 Thanks Musharof!

finally its coming out.. so happy for you guys. Kelviq fills such a big gap for us solopreneurs. Keep going 🚀🚀🚀

Maker

 Thanks for the support.

Cool stuff. Congrats on the launch. I hope Kelviq gets featured.

Maker

 Thanks for the support.

Looks neat. would try it for upcoming side projects! all the best

Maker

 Thank you Neel.

Maker

 Thanks, Neel

3.5% flat pricing is interesting curious how margins scale.

Maker

 Yeah, this is a special offer for our early customers.


As volume grows, we'll also have custom pricing for larger customers, but our goal is to keep Kelviq much more accessible than traditional MoR providers.

Great product! There is a way to migrate users, active subscriptions and license key from other MoR like LemonSqueezy or Paddle?
Maker

 Thanks! Yes, we can help with migration.


If your current provider supports PCI-compliant payment method migration, like Stripe or Paddle, we can migrate payment methods as well, so your customers don’t have to re-enter their cards.

We can also help migrate products, plans, customers, active subscriptions, discounts, files, and license keys from platforms like Lemon Squeezy or Paddle.

 So from LemonSqueezy is not possibile to migrate payment methods, to avoid my customers to re-enter their cards (or their paypal info)? Because this is the real issue to migrate from one MoR to another with an established product with tens or hundreds of customers.

Maker

 

You’re right. Payment method migration is usually the hardest part when moving from one MoR to another.

If Lemon Squeezy supports a PCI-compliant payment method export to another provider, we can help migrate payment methods so your customers don’t have to re-enter their card details.

If they don’t support exporting payment methods, we can still migrate products, plans, customers, subscriptions, files, discounts, and license keys, but existing customers may need to re-enter their payment details.

Another option is to keep existing customers on Lemon Squeezy and use Kelviq for new customers going forward. That way, you don't have to force existing customers to update their payment details immediately.

Also, if you ever want to migrate away from Kelviq in the future, we can support secure payment method migration to any PCI-compliant vault/provider that can receive the data.

So the short answer is: it depends on whether Lemon Squeezy allows secure payment method migration out of their system. We'll be happy to help you check and plan the migration properly.

Id use this over Stripe.

Maker

 Thanks Kabir!
