Best payment solutions for AI-built apps in 2026: What vibe coders need beyond built-in payments

On April 13, 2026, Lovable launched Lovable Payments: a built-in way to handle subscriptions and one-off payments through Paddle or Stripe. It’s a helpful step forward, especially for makers who want to avoid the overhead of setup and compliance.

But while built-in payments for AI apps make it easier to charge users, they don’t get you any closer to building a real software business.

Once you need things like feature-level paywalls, seat or usage limits, subscription upgrades, affiliate programs, failed payment recovery, or a proper customer portal, Lovable Payments starts to show its limits.

Whether you’re shipping on Lovable, Bolt, Replit, or any other AI builder, this guide ranks the best payment solutions for AI-built apps, with an honest look at the tradeoffs of each.

What to look for in a payment solution for AI-built apps

Consider these key differentiators:

• Merchant of record (MoR): Does it handle global VAT and sales tax?
• Subscription depth: Does it support trials, upgrades, dunning, pause/resume, proration, and annual billing?
• Feature gating / paywalls: Can specific features be locked behind a plan?
• Access control: Does it support feature gating by plan, seat limits, and AI credit tiers? Does it sync automatically with the subscription state?
• AI builder integration: Does it integrate with AI builders like Lovable, Bolt, and Replit?
• Fee structure: Is it a flat percentage, tiered volume pricing, or pay-as-you-go?
• Ownership: Can you export data and customer information?

The best payment solutions for AI-built apps

1. Freemius — for software makers who want the full monetization stack from day one

Freemius is a merchant of record for software like SaaS, AI apps, desktop tools, and WordPress products. Unlike generic payment processors, it handles global tax compliance and provides the full monetization stack software businesses need:

• Subscription billing
• Seat and credit-tier access control
• Feature-level paywalls
• Self-service customer portal
• Affiliate management
• Failed payment and cart abandonment recovery

For AI-builder users, it also offers a single-prompt integration for Lovable. With one instruction to your AI agent, you can set up a pricing page, feature-based access, webhooks, and an in-app accounts page connected to the Freemius Customer Portal.

It’s the right fit for makers building subscription-based software who need more than just a way to take payments.

Freemius key features

• Checkout: Use as an embedded overlay or standalone link. Accept credit cards and PayPal, support multiple currencies, and include upsells, coupons, and social proof.
• Feature-level paywalls: Restrict access to individual features based on subscription plan, at both UI and API level.
• Plan-based access control: Enforce feature access and usage limits (seats, credits). Entitlements update automatically on any subscription change.
• Subscription management: Offer trials (with or without payment method), upgrades, downgrades, proration, annual billing, pauses, and automated retries for failed payments.
• Cart abandonment recovery: Send automated recovery emails at 60 minutes, 24 hours, and 3 days after abandonment, with increasing incentives.
• Affiliate platform: Track referrals, manage commissions, and automate payouts through a built-in affiliate system.
• Customer portal: Let users manage subscriptions, update payment methods, download invoices, and upgrade plans independently.
• Lovable integration: Use a single prompt in your AI agent to generate the full monetization flow.

Freemius pricing

Freemius is the only payment solution that uses a transparent, progressive revenue-share pricing model, meaning you pay a lower percentage as you grow:

Fees apply only to product revenue, excluding taxes.

There are no monthly fees or extra charges for features like affiliate sales, subscription renewals, or cart abandonment recovery.

Freemius limitations

• Only for software products
• AI builder integration is currently Lovable-only (more integrations planned)
• One-time payments require a different setup than recurring payments

2. Lovable Payments — for vibe coders who want a monetized app live without leaving the editor

Lovable Payments is the built-in monetization path for apps on Lovable. You tell Lovable you want to accept payments, it creates your Paddle or Stripe account, builds the checkout flow, and wires up the UI inside the editor.

It’s the right fit for simple subscriptions or one-time payments where you don’t need feature gating or usage limits.

Lovable Payments pricing

• Paddle: 5% + $0.50 (charged on gross amount, including taxes)
• Stripe: Standard pay-as-you-go pricing (~2.9% + $0.30 for US credit card payments)

Lovable Payments limitations

• No feature-level paywalls (only full product or plan gating)
• No affiliate system
• Only one payment provider per project (Stripe or Paddle)
• Projects with payments enabled can’t be remixed or forked
• Requires Lovable Cloud (not compatible with external Supabase setups)

3. Lemon Squeezy — for developers who want a lightweight MoR for digital products

Lemon Squeezy (now owned by Stripe) is a merchant of record platform for a broad range of digital products like ebooks, templates, courses, and simple SaaS.

It handles global tax compliance, subscription and usage-based billing, with a clean UI and a developer-friendly API.

It’s a good fit for developers or creators who don’t need a platform built specifically for software and are comfortable wiring up their own Lovable integration.

Lemon Squeezy key features

• Subscription billing: Supports recurring billing, plan tiers, trials, upgrades/downgrades, pauses, proration, and dunning management.
• Usage-based billing: Tracks consumption and bills customers based on actual usage (per seat, per unit, or fully metered) via a usage reporting API.
• Customer portal: Has a hosted self-service portal where customers can manage subscriptions, update payment methods, view billing history, and download invoices.
• Embeddable checkout: Provides checkout flows that can be embedded directly into a product.
• Affiliate management: Includes built-in affiliate tracking with configurable commissions.

4. Paddle — for established software businesses with enterprise compliance needs

Paddle is one of the most established merchant of record platforms for software. It handles global VAT, sales tax, invoicing, and compliance, along with full subscription management.

As a standalone platform, you use Paddle when you need more control than a built-in setup — things like billing configuration, checkout customization, payout structure, and detailed compliance reporting.

It’s the right fit for more mature businesses selling across multiple markets, where compliance depth and enterprise-grade invoicing matter more than speed of setup.

Paddle key features

• Subscription management: Supports trials, upgrades, downgrades, proration, pauses, resumes, and dunning.
• Checkout customization: Provides overlay and inline checkout options with dashboard-based customization.
• Customer portal: Includes a hosted portal for managing subscriptions, updating payment methods, and viewing invoices.

Paddle pricing

• 5% + $0.50 (charged on gross amount, including taxes)
• 10% extra cost for cart abandonment recovery
• Microtransactions under $10 capped at 10%

Paddle limitations

• KYC/KYB verification can take weeks
• No feature-level paywalls
• Effective rate increases in high-tax markets due to fees on gross amount
• Platform keeps 5% + $0.50 on every refunded transaction
• Risk of product category restrictions, including for AI tools
• Not built for early-stage products (onboarding assumes an established business)

5. Gumroad — for creators selling a single digital product who want built-in marketplace discovery

Gumroad is one of the simplest ways to sell digital products online. It’s been around since 2011 and became a merchant of record in January 2025, adding global VAT and sales tax handling on top of its already minimal setup.

You can use it to quickly put a price on a digital product — like an ebook, template, or asset — and start selling without building any infrastructure.

It’s the right fit for solo creators selling simple digital goods who want the fastest possible path from idea to checkout, without needing subscription management or more advanced monetization logic.

Gumroad key features

• Gumroad Discover: Marketplace with 10M+ buyers for organic discovery
• Pay-what-you-want pricing: Flexible pricing where buyers choose the amount
• Digital delivery: Automatic file delivery with download limits and PDF stamping

6. Polar — for makers building AI apps that charge by usage

Polar is a payment solution built for AI-native companies and developer tools. It acts as a merchant of record for global tax compliance and supports subscriptions, one-time payments, and usage-based billing.

It also provides checkout and customer management through APIs and framework adapters.

• Customer portal: Includes a hosted portal where customers can manage subscriptions, view orders, and access plan benefits.

Polar pricing

• Extra fees for international card processing and subscriptions

Polar limitations

• No guided AI builder integration (Lovable MCP connector provides billing context only)
• No built-in affiliate system
• Higher taxes increase effective rate since fees apply to gross amount
• Subscription payments carry an additional 0.5% surcharge per renewal
• International card payments carry an additional 1.5% surcharge
• Dispute fees apply on every case, win or lose
• Manual payouts with additional payout fees

7. Creem — for co-founder teams who want built-in revenue splits alongside MoR

Creem is a newer merchant of record platform built for small business owners, indie hackers, micro-SaaS founders, and vibe coders. It started as an MoR for SaaS teams, but it positions itself as a Financial OS, handling taxes, compliance, revenue splits, and payouts in one place.

You can use it to sell digital products or SaaS quickly, set up subscriptions, and automatically split revenue between co-founders or collaborators.

It’s the right fit for small teams who need automatic revenue sharing alongside standard MoR features.

Creem key features

• Revenue splits: Splits payments between partners with configurable percentages, supporting bank transfers and crypto payouts.
• Subscription billing: Supports trials, plan changes, seat-based billing, and automated dunning for failed payments.

• AI-era DX: Includes a “skill file” for AI coding tools (e.g. Cursor, Claude, Windsurf) to help agents implement integrations faster.
• Checkout optimization: Supports upsells, bundles, order bumps, and cart abandonment flows.

Creem pricing

• 3.9% + $0.40 (charged on gross amount, including taxes)
• Extra fee for revenue splits (2%), affiliate platform (2%), and abandoned cart recovery (5%)

Creem limitations

• No native one-prompt integration with Lovable or other AI builders (AI skill file requires setup)
• No feature-level paywalls without custom development
• No usage-based billing for AI or API metering use cases
• Additional fees for several features, like affiliates (+2%), cart abandonment recovery (+5% on recovered payments), and international payouts ($7 or 1%, whichever is higher)
• Crypto payouts may introduce complications for accounting and tax reporting depending on your jurisdiction

8. Stripe — for developers who want full control and have the engineering resources to build their own billing layer

Stripe is the core payment infrastructure behind most platforms on this list. Using it directly gives you maximum flexibility and the lowest processing fees, but everything above raw payment processing services is yours to build and maintain.

They did launch Managed Payments (a per-transaction MoR service) in April 2025, but it’s still in beta and country coverage remains limited.

It’s best suited for developers with the engineering capacity to build and maintain their own billing infrastructure.

Stripe key features

• Payment processing: Supports cards, bank transfers, and 100+ local payment methods in 195+ countries.
• Stripe Checkout: Provides a prebuilt, hosted checkout page with optimized conversion flows.
• Stripe Billing: Enables subscription management with trials, upgrades, usage-based billing, and dunning, requiring setup and ongoing maintenance.
• Stripe Tax: Automates tax calculation and collection, while you remain the legal seller responsible for remittance.
• Stripe Radar: Provides chargeback and fraud protection.
• Extensive API: Offers a highly flexible API with SDKs across all major languages and frameworks.

Stripe pricing

• ~2.9% + $0.30 per transaction for US card payments
• Additional fees for international cards and currency conversion
• Extra costs for Billing, Tax, and Radar

Stripe limitations

• Managed Payments (MoR) is still in beta with limited country coverage (you remain the legal seller in most jurisdictions)
• No built-in subscription system without Stripe Billing setup and maintenance
• No feature-level paywalls without custom engineering
• Stripe Tax automates calculation but does not handle remittance (filing and paying tax authorities remains your responsibility)
• Total cost increases once add-ons and engineering time are included
• Transaction fees can vary significantly based on the payment method, region, and sales channels, with hidden fees often included in chargebacks, refunds, and withdrawal fees
• Stripe can freeze accounts or hold funds, especially for new businesses or products in higher-risk or unclear categories
• Support is ticket-based with no guaranteed response time unless you’re on a paid support plan

FAQ

Can I use Freemius with Lovable if I’m already using Lovable Payments?

Not in the same project. Lovable Payments is tied to Paddle or Stripe inside the Lovable Cloud environment. To use Freemius, you need to set it up from the start as an external integration using the Freemius Lovable integration guide. It runs alongside Lovable via Supabase Edge Functions, but it’s a separate setup from the built-in Payments flow.

Does Freemius work with Bolt or Replit, not just Lovable?

Yes. The native one-prompt setup is currently Lovable-only, but Freemius can be used with any stack that supports APIs and webhooks, including Bolt and Replit. These require manual integration. Additional AI builder integrations may be added over time.

What is a merchant of record and why does it matter for AI-built apps?

A merchant of record (MoR) is the legal entity that processes payments and handles tax compliance for you. It calculates, collects, and remits VAT and sales tax globally. Without an MoR, you’re responsible for handling tax registration and compliance in each country where you have customers. For AI-built apps selling in multiple countries, an MoR removes most of this complexity from day one.

Can I switch payment platforms later if I outgrow my initial choice?

Yes, but it’s not simple. One-time purchases are easy to move, but recurring subscriptions usually require re-authorization, which can lead to churn. This is why it’s often better to choose a platform that can scale with you from the start.

Does Lovable Payments work for apps built on Replit or Bolt?

No. Lovable Payments only works with Lovable projects running on Lovable Cloud. Apps built on other platforms need external payment providers like Freemius, Lemon Squeezy, or Stripe.

What happens if I want to add feature-level paywalls after launching with Lovable Payments?

Lovable Payments only supports gating the entire product, not individual features. If you need feature-level access control, you’ll need a custom setup — or a platform like Freemius, which supports it natively with AI builder integration.

What fees should I expect beyond the platform’s listed rate?

Every platform charges a base transaction fee, but the actual cost per sale is higher once you factor in payment gateway fees and interchange fees. Per-transaction fees charged by the customer’s bank that vary based on card type, country, and transaction risk.

Can I sell my AI-built app to customers in other countries?

Yes. Many payment processors support multiple currencies, allowing businesses to accept payments from customers around the world without needing to convert funds manually. The bigger difference between platforms is who handles the tax compliance on those international sales. Platforms that act as a merchant of record (like Freemius, Paddle, Lemon Squeezy, and others on this list) take on the VAT and sales tax liability globally, so you don’t need to register for tax in every country where you have customers.

What is a payment gateway and do I need one for my AI-built app?

A payment gateway securely transmits your customer’s payment data to the payment processor, which handles the actual movement of funds between banks. The two serve distinct roles, but are typically bundled together by providers. For most platforms on this list, both are handled under the hood — you don’t need to set them up separately or think about them at all.
