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 🙏
@sachinchoolur love the product.. all the best Sachin.. 🚀
Kelviq
@ayushtweetshere Thanks Ayush!
@sachinchoolur 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 @harsh_jhunjhunuwala during the ParityDeals 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! :)
Kelviq
@harsh_jhunjhunuwala @rohanrecommends Thanks so much, Rohan!
Really grateful for all your support, and especially for hunting Kelviq today 🙏
@sachinchoolur 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!
Kelviq
@blaize_olle 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.
Hey Sachin, congrats on the launch! Many Indian founders have been struggling with Paddle and Lemon Squeezy suddenly closing accounts or having strict entity requirements. Since Kelviq supports individuals, can you clarify how you handle payouts for Indian users (e.g., via Stripe Connect or local bank transfer) and if there are any specific compliance hurdles/GST requirements we should be aware of to ensure account longevity?
Kelviq
@abhijithbabu84
Thanks! Great question.
We use Stripe Connect for payouts. So Indian users need to complete a quick Stripe Connect onboarding, which usually takes around 5 minutes, and payouts are sent to their bank account through that flow.
Yes, we support individuals. You don’t need a company to get started with Kelviq.
If you already have a GSTIN or a registered business, we can collect those details for payout and accounting records.
Curious about the 3.5% + 40¢ number — that's a hard line in the sand vs. Stripe's 2.9% + 30¢, but you're bundling sales-tax remittance and global compliance into the same blob. For SaaS founders the implicit framing matters: is Kelviq pricing as a flat replacement for Stripe + TaxJar + Paddle MoR, or is the AI/usage-billing primitive the part you'd argue is worth a different cost basis?
In my world (project-finance modelling, where I run ModeLoop on the side), the cleanest valuation conversations always start by separating commodity-line items from differentiated ones. The bundling decision tends to be where founders either communicate or obscure unit economics. Where do you see customers landing on that vs. the underlying CPM/CPM-equivalents?
Kelviq
@samir_asadov Great question.
We don't position Kelviq as a flat replacement for Stripe processing. Stripe is great for payments, and we actually use Stripe under the hood for core payments.
The better comparison is Stripe plus tax/compliance plus the internal billing infrastructure founders usually end up building around it.
For us, the 3.5% + 40¢ is not just for payment processing. It includes the Merchant of Record layer, global tax compliance, billing logic, subscriptions, usage billing, credits, entitlements, customer portal, and the operational work around disputes and compliance.
So if someone only needs basic payment processing, Stripe will usually be the better fit.
Where Kelviq makes sense is when a SaaS or AI company does not want to spend months stitching together payments, tax, usage tracking, credits, access control, and all the edge cases around upgrades, downgrades, migrations, and plan changes.
On the usage/AI side, we don't try to hide or bundle the underlying model cost into our fee.
Customers still control their own pricing, margins, credits, units, and overage rules. Kelviq
provides the system to meter, enforce, bill, and change those models without rebuilding billing logic each time.
So the way we think about it is:
Stripe is the payment layer.
Kelviq is the monetization layer plus Merchant of Record.
And for larger volumes, we can also work with customers on custom pricing.
Congrats on the launch 🙌
Does Kelviq handle reverse-charge VAT for B2B sales within the EU automatically (valid VAT ID = no tax charged)?
Kelviq
@francesco2689 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.
@geojacobm6 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 (https://getvisibai.com), 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 🙏
Kelviq
@geojacobm6 @francesco2689 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.

Kelviq
@francesco2689 Awesome! Looking forward to it
Congrats on the launch! As a founder dealing with stripe integration right now, the idea of having payments, tax, and compliance handled in one place is really appealing. How does migration work for teams already on Stripe?
Kelviq
@tjclayton It's a comparatively easy process with Stripe. We'd mainly need to review your current pricing structure and plan setup to ensure a smooth migration.
Kelviq
@tjclayton
Thank you!
For teams already on Stripe, we can help migrate products, plans, customers, subscriptions, discounts, and payment methods where supported.
Since Stripe supports PCI-compliant payment method migration, your existing customers usually don’t need to re-enter their card details.
Happy to take a look at your current setup and suggest the cleanest path.
Kelviq
@theviolacode 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.
@sachinchoolur 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.
Kelviq
@theviolacode
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.
Congrats on the launch! Handling global tax is often the biggest hurdle for early-stage SaaS expanding internationally. How does Kelviq handle tax remittance for specific regions like the EU (VAT) compared to US sales tax? Is the 'digital delivery' feature integrated with the billing logic to automate access management upon payment?
Kelviq
@rivra_dev
We've registered in EU for tax remittance, so we handle the VAT OSS filings and reverse charges ourselves.
In the US, we manage the various state nexus thresholds and collect/remit sales tax on behalf of our users.
Regarding digital delivery: yes, the billing logic is tightly coupled. Once the payment is verified, the system triggers the delivery webhook, sends an email notification and grants access immediately, so there's no manual 'hand-off' needed.
