Best AI Builders With Built-In Payments in 2026

Introduction

There are more good ways to take payments on your own site than ever. Established platforms like Shopify and Squarespace have mature payment systems with helpful AI features, and AI app builders can now build a checkout, a membership, or a members area from a description. Both can work well, and the right one depends on what you're selling and how you want to charge for it.

They also handle the money differently, from where your payments live to what you pay in fees on top of card processing. In this post, I'll go through the AI website and app builders that can take payments in 2026, how each one handles payments, and what it costs.

Website Builders vs. App Builders

Tools that take payments fall into two groups, and the biggest difference between them is how flexible your pricing can be.

AI app builders

You describe what you want to sell in a chat, and the AI builds the checkout and member accounts for you. Since the AI writes the code, your pricing can work however you want, even if it's unusual. The main difference between these builders is where your payments live.

Website builders

Shopify, Wix, Squarespace, and Square have their own payment systems, refined over many years. Their AI mostly helps with design, and you set up what you sell yourself in a dashboard. Your pricing has to fit the options each platform offers, and some charge an extra fee on memberships.

Our Picks

Prices are the lowest plan that can take payments, billed annually where that's an option. Card fees are the standard online rate for US cards.

Tool	Best For	Free Option	Price	Card Fees
Repaint	Best overall. Payments are built into Repaint, with its own dashboard for your sales and payouts and nothing else to connect.	14-day trial	$25/mo	2.9% + 30¢
Shopify	A standard online store. Its inventory, shipping, and checkout tools are built for selling physical goods.	Free trial	$29/mo	2.9% + 30¢
Base44	Another AI builder with built-in payments. It builds checkout and memberships, with payments managed inside Base44.	Free plan	$40/mo	2.9% + 30¢
Squarespace	Content memberships on a polished site. Its members areas work well for courses and communities.	14-day trial	$19/mo	2.9% + 30¢, plus 7% on memberships
Square	Businesses that also sell in person. One payment account covers online and in-person sales.	Free plan	$0	3.3% + 30¢ (2.9% on Plus)
Wix	Businesses already on Wix. Its Pricing Plans app sells one-time and recurring plans.	Free plan	$29/mo	2.9% + 30¢, plus 4% on memberships
Lovable	Having sales tax handled for you. Its Paddle option acts as the legal seller and files sales tax for you.	Free plan	$21/mo	2.9% + 30¢ (Stripe), 5% + 50¢ (Paddle)
Replit	Technical builders on a budget. It has a low starting price and sets up customer sign-in for you.	Free plan	$18/mo	2.9% + 30¢
Bolt	Developers who already use Stripe. It builds full membership sites that run on your own Stripe account.	Free plan	$25/mo	2.9% + 30¢

AI App Builders

With an AI app builder, you build your whole site by chatting, including the parts that take payments. The AI writes the checkout and member accounts for you, and the platform hosts everything, so you never deal with code or servers directly.

This is the group I'd recommend starting with if you want to sell online without a lot of setup. The builders differ most in where your payments live. Repaint and Base44 handle payments inside their own platforms. Lovable and Replit can set up an account for you with a separate payment company, and Bolt has you connect your own Stripe account.

Repaint

How it works

Repaint is an AI builder for business websites and apps. Using it feels a lot like using ChatGPT. You describe what you want to sell, and Repaint plans it with you before building. Payments, customer accounts, and email are all built in, so there's nothing else to connect.

Review

Repaint is the AI app builder I'd recommend for most people who want to sell online, mostly because of how it handles payments. Payments are part of Repaint itself, not a service you connect. Turning them on only takes your business and bank details, and from then on, everything is in a payments dashboard inside Repaint. You can see your transactions, balance, payouts, and any disputes in one place, without ever logging into Stripe or another company's dashboard.

The checkout can also work however your business needs, since the AI writes the code. If you want a monthly membership with a cheaper yearly option, or a package of sessions, you just ask for it. Members get their own accounts where they can manage or cancel their plan.

And because your payments live in Repaint, the AI can work with them directly. You can ask how much you made this month or have it refund a customer, right in the same chat you used to build the site. Repaint charges standard card processing with no extra fee on memberships, and if you already have a website, it can import it so you can add payments without starting over.

Key features

• Payments dashboard for transactions, payouts, and disputes
• No separate payment account to connect
• One-time products, memberships, and custom pricing
• Member accounts with self-serve management
• No extra fee on memberships
• Sales and refunds managed by chat
• Imports your existing website

Base44

How it works

Base44 is an all-in-one AI app builder owned by Wix. Payments run through Base44 Payments, powered by Wix Payments, at 2.9% + 30¢ on US cards. You manage payments, payouts, refunds, and subscriptions from a Payments dashboard inside Base44. Both Base44 Payments and connecting your own Stripe account need the Builder plan or higher.

Review

Base44 is the closest alternative to Repaint for built-in payments. Its payments run through Wix Payments behind the scenes, but you manage everything from inside Base44, with no separate account to create. From one description, it can build a checkout, a monthly membership, and a member portal where customers can cancel.

The main tradeoff is price. Taking real payments needs the Builder plan at $40 a month, which makes it one of the more expensive options here for a small business. Base44 also shows more technical detail as it builds, though you can mostly ignore it.

Key features

• Base44 Payments powered by Wix, managed inside Base44
• Subscriptions with a member portal
• One-click payment setup in chat
• Built-in login and database
• Owned by Wix

Lovable

How it works

Lovable builds full web apps from a description. On its paid plans, Lovable Payments creates a Stripe or Paddle account for you and builds the checkout, so there are no keys to handle. You still have an account with that provider, and things like payouts, checkout styling, and payment methods are managed in its dashboard. On the free plan, you can connect your own Stripe account by pasting a Stripe API key into the chat.

Review

Lovable is a good fit if you want sales tax handled for you. If you choose Paddle for payments, Paddle acts as the legal seller and collects and files sales tax and VAT on your behalf, for 5% + 50¢ per transaction. With Stripe, you pay standard rates and handle taxes yourself. Lovable doesn't add its own fee either way.

The main difference from Repaint and Base44 is where your payments live. Lovable sets up a Stripe or Paddle account for you, so payouts and payment settings are handled in that company's dashboard rather than in Lovable. Its built-in payments need a paid plan, and Lovable puts more of the technical side in front of you, like its code view and database.

Key features

• Stripe or Paddle account set up for you on paid plans
• Optional sales tax handling through Paddle
• Subscriptions with a hosted customer portal
• No Lovable fee on payments
• Code view and GitHub sync

Bolt

How it works

Bolt builds apps in a browser-based code editor, with hosting, a database, and logins set up through Bolt Cloud. Payments run through your own Stripe account, which you connect by pasting your Stripe secret key into Bolt.

Review

Bolt is a good fit for developers who already have a Stripe account. It can build a full membership site with sign-up, login, and a member dashboard in a few minutes. Once Stripe is connected, it supports subscriptions, trials, and pricing tiers, with no Bolt fee on payments.

Connecting Stripe is the hard part if you're not technical. Before it builds payments, Bolt asks you to create a Stripe account and paste in a secret key from its developer settings, and checkout stays a placeholder until you do. Bolt also shows its work the way a developer would expect, which can be a lot to take in.

Key features

• Subscriptions and tiers through your own Stripe account
• Built-in logins and database through Bolt Cloud
• No Bolt fee on payments
• Code editor and GitHub export

Replit

How it works

Replit's AI agent builds apps in almost any language, for the web or for phones. Customer sign-in is set up automatically. For payments, it asks you to connect either Stripe, which is available on paid plans and needs your own verified Stripe account, or Whop, which creates a payments account for you and handles checkout and identity checks.

Review

Replit is a good fit for technical builders who want a low starting price. Customer sign-in works with no setup at all. For payments, you can connect your own Stripe account or let Replit create a Whop account for you, which handles checkout and identity checks. Replit doesn't add its own fee on payments.

It's also one of the more technical tools here. Its workspace includes a file browser and a terminal, and connecting Stripe needs a paid plan. Building a full membership site can also use up the free plan's daily allowance before it's done.

Key features

• Payments through Stripe or Whop
• Automatic customer sign-in
• Web and mobile apps
• No Replit fee on payments

Website Builders

Website builders like Shopify and Wix were built around templates and dashboards long before AI, and their payment systems are mature and reliable. Their AI mostly helps with design and writing. You set up your products, plans, and payments yourself, within the options each platform offers.

They're a great fit when your business matches what the platform was built for, like running a standard online store on Shopify or taking payments in person with Square. For a standard online store, setting things up in Shopify is often less work than building the same thing with an AI app builder. For memberships and custom pricing, an AI app builder is usually simpler, and it avoids the extra membership fees some of these platforms charge.

Shopify

How it works

Shopify is an ecommerce platform with an AI store builder that generates a store design from a description, and an AI assistant called Sidekick for running your store. You set up products and subscriptions yourself, with subscriptions running through the free Shopify Subscriptions app. Shopify Payments charges 2.9% + 30¢ on US cards on the Basic plan.

Review

Shopify is a strong choice for a standard online store selling physical goods, with mature tools for inventory, shipping, and checkout. Customer accounts are built in, and subscribers can skip, pause, or cancel through their account.

Its AI is genuinely useful too. Sidekick can help set up and run your store, though it works within Shopify's screens, and you still do much of the setup yourself. Shopify is built around stores rather than memberships or services, so a membership business only uses a small part of it. Using a payment provider other than Shopify Payments also adds a 2% fee on the Basic plan.

Key features

• AI store builder and Sidekick assistant
• Shopify Payments with no extra transaction fee
• Free Shopify Subscriptions app
• Customer accounts with self-serve subscription management
• Inventory and shipping tools

Wix

How it works

Wix's AI builder creates a website from a chat, and sells memberships through its Pricing Plans app. Payments run through Wix Payments, at 2.9% + 30¢ on US cards, or through PayPal and other providers. Accepting payments needs the Core plan or higher.

Review

Wix is a reasonable choice if your site is already on Wix. Its Pricing Plans app sells one-time and recurring plans, with member logins and a members area included.

Memberships cost extra, though. Wix charges a transaction fee on Pricing Plans payments of 4% on the Core plan and 2% on Business, on top of card processing. Its AI can suggest plans, but you set them up yourself in the dashboard.

Key features

• Wix Payments built in
• Memberships through the Pricing Plans app
• Member logins and a members area
• Transaction fee on memberships below Business Elite

Squarespace

How it works

Squarespace's AI builder, Blueprint, walks you through a series of choices about your site. Memberships run through its Member Sites feature, with a paywalled members area. Payments run through Squarespace Payments, Stripe, or PayPal.

Review

Squarespace is a good fit for content memberships, like courses and communities, on a polished site. Its Member Sites feature puts content behind a paywall, customers can cancel their own subscriptions, and an optional add-on calculates sales tax.

Memberships are expensive on the cheaper plans. Squarespace charges 7% on membership payments on the Basic plan, 5% on Core, and 1% on Plus. Its AI tools stick to design and writing, so you set up your products and plans yourself.

Key features

• Squarespace Payments, Stripe, or PayPal
• Member Sites with paywalled content
• Self-serve subscription cancellation
• Optional sales tax add-on
• Polished website designs

Square

How it works

Square Online is Square's website builder, connected to the same payment system as Square's in-person card readers. Payments run through Square after you verify your business identity. Selling subscriptions on your site needs the Plus plan.

Review

Square is a great fit if you already sell in person with Square, since your online and in-person sales share one account. Its free plan sells one-time items, and subscribers can update their card, pause, or cancel from a link in their emails.

Memberships cost more, though. Subscriptions on your site need the Plus plan at $49 a month, and the free plan charges a higher online card rate of 3.3% + 30¢. Square Online also has no AI builder, so you set up the site yourself.

Key features

• One payment account for online and in-person sales
• Free plan for one-time sales
• Subscriptions on the Plus plan
• Self-serve subscription management by email link

Conclusion

Most AI website and app builders can show a price, but they handle the money very differently. AI app builders can build almost any way of charging customers, and the best of them keep payments inside the platform. Website builders have mature payment systems, but your pricing has to fit their options, and some take an extra cut of memberships.

Repaint is the easiest place to start. Its payments are built into the platform, with a dashboard for your sales and payouts, and it can build whatever pricing your business needs. Base44 is the closest alternative at a higher plan price, and Lovable stands out if you want sales tax handled for you. For a standard online store selling physical goods, Shopify is often still a good option, especially if you want its built-in shipping and inventory tools.

Most of these tools have a free plan or trial, so it's easy to try a couple before you commit.

FAQ

What is the best AI builder with built-in payments?

Repaint is the best for most people who want to sell online without technical setup. Payments are built into the platform, with a dashboard in Repaint for your transactions, payouts, and disputes, so there's nothing else to connect. Base44 is the closest alternative, and Shopify is a strong option for a standard online store.

Which AI website builders have built-in payments?

Repaint and Base44 both keep payments inside their own platforms, so you never set up a separate payment account. Base44 needs its $40 Builder plan for this. Most other AI app builders, like Lovable and Bolt, run payments through a Stripe account that you manage separately.

Do I need a Stripe account to take payments on an AI-built website?

Not always. Repaint and Base44 handle payments themselves, so you never create a separate payment account. Lovable can create one for you on its paid plans, while Bolt and Replit usually ask you to connect your own.

Can an AI builder handle memberships or custom pricing?

Yes. AI app builders write the checkout for your business, so your pricing can work however you need, whether that's a membership with a yearly discount or a package of sessions. Website builders support memberships too, but only within the options their membership features offer.

How much does it cost to take payments with an AI builder?

Most builders charge standard card processing, around 2.9% + 30¢ on US cards, on top of the plan price. Plans that can take payments start around $18 to $40 a month. Repaint starts at $25 a month, with no extra fee on memberships.

Which website builders charge extra fees on memberships?

Wix and Squarespace both do. Wix charges 4% on membership payments on its Core plan and 2% on Business, and Squarespace charges 7% on Basic, 5% on Core, and 1% on Plus. Repaint, Base44, and Lovable don't add a fee on top of card processing.

Who handles sales tax when I sell online?

On most platforms, you do. As the seller, you're responsible for collecting and filing sales tax, though many builders can calculate it at checkout. In Repaint, you can describe your tax rules and the AI adds them to your checkout. Lovable's Paddle option is the main exception, since Paddle acts as the legal seller and files tax for you.

Can customers cancel their own subscriptions?

Yes, on most builders that support subscriptions. Repaint builds member accounts where customers can update their card or cancel, and most website builders let customers cancel from their account.
