I will review 5 Next.js SaaS landing/payment flows today

Most early SaaS launches do not fail because the app has no features.

They fail because the first-revenue path is not clear enough:

• the landing page does not explain the outcome
• the CTA points to a weak next step
• pricing is hidden or confusing
• checkout is disconnected from the product promise
• webhooks exist, but access unlock is not tested
• failed payments and recovery paths are ignored
• the deployed app has small broken states that scare buyers away

I am reviewing 5 Next.js SaaS landing/payment flows today.

If you are building with Next.js, Stripe, Polar, Lemon Squeezy, or a SaaS boilerplate, drop your URL in the comments and I will reply with 2 concrete issues I would fix first.

What I will look at

1. Landing page clarity

Can a new visitor understand who the product is for, what pain it removes, and what happens after clicking the CTA?

2. Pricing path

Is there a visible route from interest to payment, or does the user need to guess how to buy?

3. Checkout handoff

Does checkout match the plan, product, and promise on the page?

4. Webhook and access unlock

After payment, does the right user or organization get the right access without manual work?

5. Recovery paths

What happens when payment fails, a webhook retries, an email is missed, or a user comes back later?

If you want the deeper version

I also packaged this into a small paid audit:

https://productized-webdev.vercel.app/audit

It covers landing CTA, pricing, checkout, webhook/access unlock, deployment blockers, and the exact implementation path.

I wrote the payment checklist I use here:
