If you are building a SaaS product, your website and billing system are tied together. The site needs to explain the product, get users signed up fast, and collect payments without friction. Most builders are either too simple or too restrictive. They focus on design or ecommerce, not on subscription flows or recurring payments.

To write this guide, we looked at what the top ranking pages cover. They focus on payment processors like Stripe and GoCardless, or general website builders like Wix and Shopify. None of them compare these tools through the lens of a SaaS startup. None talk about product onboarding, user activation, subscription logic or custom billing pages.

So that is what this guide fixes. We will walk through the main builders, the main payment systems, what they do well, what they lack, and why Webflow ends up being the most reliable choice when you want design freedom and a stable payment stack that can grow with your product.

1. What SaaS companies actually need from a builder

Most review sites talk about price, templates and drag and drop features. None of them address what a real SaaS product needs in order to grow.

Here is the short version of what matters:

• A fast site that loads clean on mobile
• Custom pricing pages and comparison tables
• A way to connect signup forms to your backend
• Easy integration with Stripe, Paddle or Lemon Squeezy
• The freedom to design onboarding flows without limits
• A CMS that can handle docs, blogs, updates and help content
• SEO control so you can grow organic traffic
• No forced layout that stops you from building what your funnel needs

Most builders fail one of these points. Wix and Squarespace limit layout control and custom logic. Shopify is built for online stores and product SKUs, not subscriptions. The traditional CMS route adds dev time and slows you down.

This is why most SaaS founders end up with Webflow as their front end and a dedicated payment provider as their billing engine.

2. Comparing the top website builders for SaaS

Wix

Wix is great for small businesses that need a simple site. It has templates, AI tools, and built in apps. But for SaaS, it hits limits fast.

Strengths:

• Easy to use
• Plenty of templates
• Working payment options
• Quick setup

Weaknesses for SaaS:

• Hard to build custom signup flows
• Limited design control for product onboarding
• Poor control over structure for long term scale
• App ecosystem is not built for subscriptions
• Code embeds feel like hacks when you need serious logic

You can build a landing page on Wix. You cannot build a serious SaaS site that needs flexible layouts and external billing integration.

Squarespace

Squarespace is popular for portfolios and creative brands. Clean templates, simple editor, and good visuals. But for SaaS, it fails in the same ways Wix does.

Strengths:

• Very easy for beginners
• Nice templates

Weaknesses:

• Tight design restrictions
• Weak integration options for payments
• Not built for user dashboards or complex routing
• No real control over structured content

For SaaS, Squarespace is too limited.

Shopify

Shopify is powerful, but it is an ecommerce platform first. If your business sells subscriptions as a product, it can help you. If you need SaaS onboarding, user accounts and software logic, you will hit a wall.

Strengths:

• Amazing for physical products
• Strong checkout experience
• Trusted

Weaknesses for SaaS:

• Pricing structure made for stores
• Subscription apps are rigid
• Hard to build a SaaS funnel
• Overkill for anything not ecommerce

Shopify is the wrong tool for SaaS, unless your SaaS also sells physical products.

Hostinger and GoDaddy

Good for beginners, terrible for SaaS. Both builders lack the structure, flexibility and integrations needed for SaaS subscription workflows.

3. The real players in SaaS payments

The top ranking pages do a great job comparing payment processors. Here is what they get right and where they miss important points for SaaS teams.

Stripe

The strongest payment processor for SaaS. Global reach, reliable API, flexible subscription billing.

Pros:

• Supports all subscription models
• Works with Webflow, Memberstack, Outseta, Lemon Squeezy
• Low code or full API options
• Automatic tax tools

Cons:

• Needs integration
• Requires a front end that can handle custom flows

Stripe plus Webflow plus Memberstack is one of the cleanest setups for SaaS founders.

Paddle

Great for SaaS because it is a merchant of record. Handles tax, VAT, global payments and compliance.

Pros:

• Built for SaaS companies
• Handles global tax
• Clean checkout

Cons:

• Less flexible than Stripe
• You give up some control

Still works well with Webflow.

Lemon Squeezy

A modern alternative that is easy to set up for subscriptions.

Pros:

• Quick setup
• Good UI
• Works well with Webflow

Cons:

• Smaller ecosystem than Stripe

Braintree, GoCardless, Worldpay

Good processors, but not built specifically for SaaS. Stripe, Paddle or Lemon Squeezy are better choices unless you have a niche use case.

4. Why Webflow wins for SaaS websites with integrated payments

Now we bring it together. You need two things:

• a powerful front end
• a reliable payment provider

Most builders force you to choose between design and payments. Webflow gives you both.

What Webflow does that other builders cannot do

1. Full design freedom.
You can build any layout. Pricing pages, signup flows, onboarding screens, dashboards, comparison tables. No locked templates.

2. CMS built for SaaS content.
Docs, blogs, updates, changelogs, feature pages.

3. Clean performance.
Fast hosting, clean code, real SEO control.

4. Integrates with all major SaaS payment stacks:

• Stripe
• Paddle
• Lemon Squeezy
• Braintree
• PayPal
• Custom API billing
• Outseta (all in one SaaS backend)
• Memberstack (auth plus payments)

Other builders either limit integration or make you hack scripts into the page.

5. Works with your real product backend.
Authentication, webhooks, signup flows and user dashboards are far easier when your front end does not fight you.

6. Scales without needing a rebuild every six months.
This is a major point missing from the competitor articles. Scaling a SaaS site usually means more pages, more states, more pricing experiments, more growth loops. If your builder gets in the way, your product slows down.

Webflow is the only front end builder that stays flexible as your SaaS grows.

5. What the top ranking pages are missing

Here is where we beat them.

They never consider SaaS specifically.
They compare generic website builders or generic payment processors.

They ignore subscription logic and onboarding flow.
SaaS lives or dies on signups and user activation.

They assume payments live inside the builder.
Real SaaS teams use Stripe or Paddle. The builder is the front end, not the processor.

They never mention Webflow in the payment context.
Webflow plus Stripe or Paddle is the industry standard for early stage SaaS.

They skip growth requirements like:

• A/B testing
• Pricing experiments
• Feature rollouts
• Multi step signups
• SEO scale
• Documentation systems

Your blog includes all this, which is why it will rank above them.

6. The best website builder for SaaS payments: Webflow

Here is the clear conclusion that still feels natural.

If you want a clean landing page, use Wix.
If you want a beautiful portfolio, use Squarespace.
If you want to sell T shirts, use Shopify.

If you want to launch and scale a SaaS product with subscription payments, onboarding flows and flexible design, you use Webflow.

Webflow gives you:

• Complete design control
• Fast hosting
• A CMS that grows with your product
• Easy integration with Stripe, Paddle and Lemon Squeezy
• Room to build real SaaS architecture
• A setup your dev team does not hate

This is why top SaaS founders and YC teams pick Webflow early.

Final Verdict

The best setup for SaaS websites with integrated payments is:

Webflow as the front end
paired with
Stripe, Paddle, Lemon Squeezy or Memberstack for billing and subscriptions

It gives you:

• freedom
• performance
• flexibility
• scalability
• the ability to improve fast without redesigning everything

No other builder hits all of this.
