The Complete SaaS Launch Checklist: 27 Things You Need Before Going Live#

You've been building for months. The features work. The UI looks good. You're ready to launch your SaaS product. But are you actually ready? Most founders skip critical steps in the rush to go live, then spend weeks fixing things that should have been handled before a single customer signed up.

We've helped launch multiple SaaS products at Infinity Sky AI, including our founder's own platform, Channel.farm. Every launch teaches the same lesson: the product is only half the equation. Payments, onboarding, security, legal, analytics, support infrastructure. Skip any of these and you're setting yourself up for a painful first week.

This checklist covers everything you need before flipping the switch. Not theory. Not "best practices" from someone who's never shipped. These are the 27 things we verify on every SaaS launch we do.

Section 1: Core Product Readiness (Items 1 to 7)#

Before anything else, your product needs to actually work. Not "works on my machine" work. Works for real users with real data in real conditions.

• Authentication flows are bulletproof. Sign up, login, password reset, email verification. Test every path. Test what happens when someone enters a wrong password five times. Test what happens when the verification email link expires. These are the first things every user touches, and broken auth kills trust instantly.
• Core user journey works end to end. Pick the single most important thing a user does in your product. Walk through it as a brand new user. Does it make sense? Can you complete it without guessing? If not, fix it before launch.
• Error handling is human-readable. No stack traces. No "undefined is not a function" messages. Every error should tell the user what happened and what to do next. This includes API errors, form validation, network failures, and edge cases.
• Mobile responsiveness is tested on real devices. Not just Chrome DevTools. Actually pull it up on an iPhone and an Android phone. Check every critical screen. Forms are especially brutal on mobile.
• Loading states exist everywhere. Every button that triggers an action should show it's doing something. Every page that fetches data should show a loading state. Users who click a button and see nothing happen will click it again. And again.
• Empty states are designed. What does the dashboard look like with zero data? What does the project list look like before the first project? Empty states are your onboarding. Use them to guide users toward their first action.
• Browser compatibility is verified. At minimum: Chrome, Safari, Firefox, Edge. You don't need to support IE, but you'd be surprised how many SaaS products break in Safari.

Section 2: Payments and Billing (Items 8 to 12)#

This is where most first-time founders get nervous, and for good reason. Getting payments right is non-negotiable. Money touches everything: trust, legal compliance, your actual revenue.

• Payment processing is live and tested. If you're using Stripe (you probably should be), switch from test mode to live mode. Run a real transaction with a real card. Verify the money actually hits your account. Then test a refund. Then test a failed payment.
• Subscription lifecycle is handled. What happens when a card expires? When a payment fails? When someone upgrades mid-cycle? When they downgrade? When they cancel? Each of these scenarios needs a defined behavior. Most payment processors handle the mechanics, but your app needs to respond correctly to each webhook event.
• Invoices and receipts are generated. Depending on your market, this might be legally required. At minimum, customers should be able to access their billing history and download receipts. Stripe handles this well out of the box.
• Free trial logic is airtight. If you offer a trial, define exactly what happens when it ends. Does the user lose access? Get downgraded to a limited free tier? Get a grace period? Design your trial to convert, but make the end-of-trial experience clear and fair.
• Pricing page is clear and final. Your pricing should be published, easy to understand, and not require a PhD in mathematics. If you're still unsure about pricing, that's a separate problem. But launch with something concrete.

Section 3: User Onboarding (Items 13 to 16)#

A user who signs up and doesn't know what to do next is a user who churns. Your onboarding flow is arguably more important than any individual feature.

• Welcome email is set up and tested. When someone signs up, they should get an email within seconds. Not a generic "Welcome to our platform" email. A useful one that tells them exactly what to do next. Include a direct link to their first action.
• First-use experience is guided. Whether it's a setup wizard, a checklist, tooltips, or a quick video, new users need direction. The goal: get them to their first "aha moment" as fast as possible. For a project management tool, that's creating their first project. For an analytics tool, that's connecting their first data source.
• Sample data or templates exist. Nothing is worse than staring at an empty product wondering what it does. Pre-populate with sample data or offer templates they can start from. Let users see the product's value before they invest time creating their own content.
• Help documentation is accessible. You don't need a 200-page knowledge base on day one. But you need answers to the obvious questions: How do I do X? What does Y mean? Where do I find Z? A simple FAQ page or a few help articles covering the core workflow is enough.

Section 4: Security and Infrastructure (Items 17 to 21)#

Security isn't optional, even for an MVP. You're handling user data and payment information. A breach at launch could end your product before it starts.

• SSL is active on all pages. This should be obvious in 2026, but verify it. Every page, every subdomain, every API endpoint should be served over HTTPS. No mixed content warnings.
• Environment variables are secured. No API keys in your codebase. No database passwords in config files committed to Git. Use environment variables and a secrets manager. Audit your repo for any accidentally committed secrets.
• Database backups are automated. Set up daily automated backups before you have users, not after you lose data. Test a restore to make sure the backups actually work. A backup you've never tested is not a backup.
• Rate limiting is in place. Your API endpoints need rate limiting to prevent abuse. Your login endpoint especially. Without rate limiting, a single bad actor can bring down your service or brute-force accounts.
• Basic monitoring and alerting is configured. You need to know when your app goes down before your users tell you. Set up uptime monitoring, error tracking (Sentry or similar), and basic performance monitoring. Configure alerts for downtime and error spikes.

Section 5: Analytics and Tracking (Items 22 to 24)#

If you can't measure it, you can't improve it. And after launch, you'll need data to make every decision.

• Product analytics are tracking key events. Sign ups, onboarding completion, feature usage, upgrade clicks, churn triggers. You don't need to track everything. But you need to track the events that tell you if your product is working. Tools like PostHog, Mixpanel, or even simple custom event logging work fine.
• Website analytics are configured. Google Analytics, Plausible, or Fathom on your marketing site. Know where your traffic comes from, which pages convert, and where people drop off. Set up conversion goals for sign-up and upgrade.
• Error tracking is capturing production issues. Sentry, Bugsnag, or LogRocket. You need to see every error your users encounter, with enough context to reproduce and fix it. This is different from monitoring. Monitoring tells you the house is on fire. Error tracking tells you which room and why.

Section 6: Legal and Compliance (Items 25 to 27)#

Nobody's favorite topic, but ignoring legal basics can get expensive fast.

• Terms of Service and Privacy Policy are published. You need both. They need to be accessible from your sign-up flow and your website footer. You can use a generator or template to start, but if you're handling sensitive data or operating in regulated industries, invest in a lawyer.
• Cookie consent is implemented (if applicable). If you serve users in the EU, you need GDPR-compliant cookie consent. If you serve users in California, CCPA applies. This doesn't have to be complicated, but it does have to exist.
• Data handling practices are documented. Where is user data stored? Who has access? How long do you retain it? What happens when someone requests deletion? You don't need to publish all of this on day one, but you need to have answers. And your Privacy Policy should reflect reality.

The Pre-Launch Test We Run on Every Product#

At Infinity Sky AI, we run what we call the "fresh eyes test" before every launch. We hand the product to someone who's never seen it. No context, no walkthrough, no hints. We watch them try to sign up, figure out what the product does, and complete the core action.

Every time, without fail, this test reveals something we missed. A confusing label. A button that looks disabled but isn't. A step in the onboarding that makes perfect sense to the builder but none to the user. It takes 30 minutes and saves you days of post-launch firefighting.

If you only do one thing from this checklist beyond the basics, do the fresh eyes test.

When to Launch (and When to Wait)#

Here's the tension every founder faces: you want to launch fast, but you also want to launch right. The answer isn't "launch when it's perfect" because it never will be. The answer is: launch when every item on this checklist is handled, even if some features are still missing.

Features can be added after launch. Broken payments, missing legal pages, zero onboarding, and no error tracking cannot be fixed gracefully after users are already in the product. The checklist above represents the minimum infrastructure for a professional SaaS launch. Your MVP feature set is a separate decision.

If you're building an AI-powered SaaS product and want help getting launch-ready, we build and launch SaaS products from MVP to production. Our process follows the Build, Validate, Launch framework that ensures you're not just shipping code, you're shipping a product people will pay for.
