Built Your Website with AI? Here’s How to Accept Payments in the UK & Europe

AI-built ecommerce website connected to Pay by Bank through Wallid Open Banking technology
AI tools can help you build a website or app quickly, but they don’t automatically set up payments for your business. To start accepting money, you still need to choose payment methods, connect a provider, and create a working checkout. In the UK and Europe, common options include cards, digital wallets, Pay by Bank, and bank transfers. The right setup depends on your business model, your customers, and how much control you want over the payment experience.

Key takeaways

  • AI tools such as Lovable, Bolt, Replit, and V0 can help build websites and applications, but merchants still need to connect a payment provider before they can accept customer payments.
  • AI-built websites can accept payments through APIs, hosted checkout pages, or payment links without moving to Shopify or WooCommerce.
  • Cards, digital wallets, Pay by Bank, and traditional bank transfers serve different customer and business needs. Many merchants benefit from offering more than one suitable payment method.
  • The right payment setup depends on the business model, customer location, payment preferences, recurring-payment requirements, provider eligibility, and the level of checkout control required.
  • Pay by Bank allows customers to pay directly from their bank accounts through Open Banking and can be offered alongside cards and digital wallets.
  • Wallid provides an API-friendly Pay-by-Bank solution that can be integrated into custom AI-built websites and applications without requiring merchants to rebuild their businesses on a traditional ecommerce platform.
In this article, we cover how to accept payments on an AI-built website, which payment methods to consider, and how to choose the right setup for your business.

Why building your website isn’t enough to start taking payments

AI tools like Lovable, Bolt, Replit, and V0 can help you build a website or app in hours instead of weeks.
But launching a site isn’t the same as launching a business.
If you want to actually make money — selling products, subscriptions, or services — you still need to set up payments. And AI builders don’t handle that for you.
To accept payments, you need to:
  • Choose the right payment methods
  • Connect a payment provider
  • Set up a checkout that works for real customers
In the UK and Europe, the most common options are cards, digital wallets, Pay by Bank, and traditional bank transfers. The right setup depends on your business model, your customers, and how much control you want over the payment experience.

How to accept payments on an AI-built website

Yes — AI-built websites can accept payments.
But they don’t do it automatically.
You need to connect a payment provider using one of three methods:
  • API (full control)
  • You build payments directly into your app or website. Best for custom products, SaaS, or marketplaces.
  • Hosted checkout (simpler setup)
  • You send users to a secure payment page managed by the provider.
  • Payment links (fastest option)
  • You generate a link customers can click to pay — ideal for services or early-stage launches.
You do not need Shopify or WooCommerce to accept payments. Those platforms bundle ecommerce tools, but AI-built websites can connect directly to payment providers.
Common providers include:
  • Cards & local methods: Stripe, Adyen, Mollie
  • Wallets: PayPal
  • Pay by Bank: Wallid (via Open Banking)

Why payments still require planning

AI can generate layouts and code — but payments involve real money, real customers, and real risk.
That means you need to think beyond just adding a “Pay” button.
Before launching, you should understand:
  • How your checkout flow works
  • What happens if a payment fails
  • How refunds are handled
  • Whether your provider supports your business
  • How payments connect to orders, users, or subscriptions
Skipping this step can lead to broken checkouts, lost revenue, or delays in getting approved by providers.

What matters before you launch

Even if your site looks finished, your payment setup might not be.

Checkout

Your checkout should:
  • Clearly show what the customer is buying
  • Display the correct price
  • Offer relevant payment methods
  • Work smoothly on mobile
  • Confirm success or failure clearly
A poor checkout experience is one of the biggest causes of lost sales.

Payment provider

Your provider handles:
  • Processing transactions
  • Security and fraud checks
  • Payment confirmation
  • Sending funds to your account
Not all providers support all business types or countries — so choosing the right one matters.

Eligibility

Payment providers may review:
  • What you sell
  • Where you operate
  • Your pricing and refund policies
  • Whether your business is considered high-risk
Always check this early — not after building your entire checkout.

Refunds & subscriptions

Think beyond the payment itself:
  • Can you issue refunds easily?
  • How long do refunds take?
  • Do you need recurring billing?
  • What happens if a subscription fails?
These are business decisions, not just technical ones.

Payment methods explained

Most businesses use more than one payment method.
Payment method Best for Key benefit Main consideration
Cards Most online businesses Familiar and widely accepted Fees, fraud, disputes, and chargebacks may apply
Digital wallets Fast and mobile checkout Customers can use saved payment details Availability varies by provider, country, and device
Pay by Bank Direct bank payments and payment diversification Customers pay from their bank accounts without entering card details Availability depends on supported banks and markets
Bank transfers B2B payments, invoices, and high-value transactions Useful outside a standard online checkout Confirmation and reconciliation may require manual work

Cards

Cards are still the default for online payments.
They’re widely accepted but come with:
  • Processing fees
  • Chargebacks
  • Fraud risk

Wallets

Wallets like PayPal, Apple Pay, and Google Pay reduce friction at checkout.
They’re especially effective on mobile but depend on user setup.

Pay by Bank (Wallid)

Pay by Bank lets customers pay directly from their bank account using Open Banking.
Instead of entering card details, the customer:
  1. Selects their bank
  2. Logs in securely
  3. Approves the payment
Wallid enables this via API, making it easy to integrate into AI-built websites and custom apps.
It’s useful for:
  • Reducing reliance on cards
  • Offering alternative payment options
  • Supporting direct account-to-account payments
  • Building flexible checkout flows
Most businesses use Pay by Bank alongside cards — not instead of them.

Bank transfer

Traditional bank transfers are mainly used for:
  • Invoices
  • B2B payments
  • High-value transactions
They’re slower and require manual tracking, so they’re less suited for automated checkouts.

Which payment setup is best?

There’s no single “best” option.
The right setup depends on your business.
Ask yourself:
  • Where are your customers located?
  • Do you need subscriptions or one-time payments?
  • What payment methods do customers expect?
  • What are the costs and risks?
  • How much control do you need?
Most businesses combine methods — for example, cards + Pay by Bank — to improve flexibility and reduce dependency on one provider.

Integration options explained

Your integration choice affects both speed and flexibility.
Option How it works Best suited to Customization Setup effort
API Connects the website directly to the payment provider Custom stores, SaaS apps, marketplaces, and platforms High Higher
Hosted checkout Uses a checkout page managed by the payment provider Merchants that want a structured checkout with less development Medium Medium
Payment link Opens a provider-managed payment page through a link Services, invoices, early launches, and simple payments Low Low

API

Best for full control.
Ideal for:
  • SaaS platforms
  • Marketplaces
  • Custom ecommerce flows

Hosted checkout

Best for simplicity.
You redirect users to a provider-managed page and return them after payment.

Payment links

Best for speed.
Ideal for:
  • Early-stage businesses

Common mistakes to avoid

AI speeds up development — but it doesn’t replace decision-making.
Avoid these common mistakes:
  • Assuming AI tools handle payments automatically
  • Choosing a provider without checking eligibility
  • Offering only one payment method
  • Treating Pay by Bank like manual transfers
  • Skipping testing (especially mobile)
  • Launching without refund or subscription policies
Fixing these early prevents lost revenue and delays.

Do you need Shopify or WooCommerce?

No.
You can accept payments on an AI-built website using:
  • APIs
  • Hosted checkout
  • Payment links
Shopify and WooCommerce can simplify ecommerce — but they’re not required.

Final takeaway

AI can build your website — but it won’t build your payment system.
To start accepting payments, you need to:
  • Choose the right payment methods
  • Select a suitable provider
  • Pick an integration approach
Wallid helps you add Pay by Bank via API, giving you a direct bank payment option alongside cards and wallets.
With the right setup, your AI-built website can accept payments reliably — without switching platforms or starting over.

Frequently asked questions

Can an AI-built website accept payments?

Yes. A website or application built with AI can accept payments when it is connected to a payment provider. Payments can usually be added through an API, a hosted checkout, or a payment link. The available payment methods may include cards, digital wallets, Pay by Bank, and traditional bank transfers.

How do I add payments to a website built with Lovable, Bolt, Replit, or V0?

First, choose a payment provider that supports your business model and target markets. You can then connect the provider through an API, use a provider-managed hosted checkout, or direct customers to a payment link. The right option depends on whether you need a custom checkout, subscriptions, customer accounts, or a faster launch with less development work.

Do I need Shopify or WooCommerce to accept payments?

No. Custom websites and AI-built applications can connect directly to payment providers through APIs, hosted checkout services, or payment links. Shopify and WooCommerce can simplify ecommerce operations, but they are not required to accept online payments.

What is the easiest way to add payments to an AI-built website?

Payment links are often the fastest option because they require less integration work. Hosted checkout can provide a more structured customer journey, while an API offers greater control and customization. The easiest option is not always the best long-term choice, so merchants should also consider subscriptions, order management, customer experience, and future growth.

What is the difference between an API, hosted checkout, and payment link?

An API connects the website or application directly to a payment provider and supports a more customized payment experience. A hosted checkout sends customers to a payment page managed by the provider. A payment link opens a separate payment page through a shareable link and usually requires the least setup.

Can an AI-built website use Pay by Bank?

Yes. An AI-built website can offer Pay by Bank when it is connected to an Open Banking payment provider. Customers can select their bank and approve the payment through their bank’s usual authentication process instead of entering card details.

Is Pay by Bank the same as a traditional bank transfer?

No. Pay by Bank creates a connected online payment journey in which customers select their bank and approve the payment through their bank’s usual process. A traditional bank transfer often requires customers to enter payment details manually and may require merchants to match payments to orders themselves.

Can I offer Pay by Bank alongside cards and digital wallets?

Yes. Pay by Bank can be offered alongside card payments, PayPal, digital wallets, and other suitable payment methods. Combining payment options can give customers more choice and help merchants reduce their dependence on a single payment provider or payment method.

Does Wallid work with AI-built websites and applications?

Yes. Wallid provides Pay by Bank through Open Banking and can be integrated into custom websites and applications through an API. This allows eligible businesses using Lovable, Bolt, Replit, V0, or other AI-assisted development tools to add direct bank payments without rebuilding their websites on Shopify or WooCommerce.

How do I choose the right payment provider for an AI-built website?

Compare providers based on supported payment methods, customer countries, business eligibility, transaction costs, recurring-payment requirements, refund support, checkout experience, and integration options. There is no single provider that is best for every AI-built business, and many merchants use more than one payment method.
