SaaS Launch Checklist: 50-Point Pre-Launch, Launch Day & Post-Launch Guide (2026)

Launching without a checklist is like shipping code without tests. Something will break. Probably in public.

This is the exact pre-launch → launch → post-launch checklist that covers every dimension: landing page, analytics, payments, legal, and distribution. Work through this over 7 days before you go live.

Overview: The 3-Phase Launch System

PRE-LAUNCH (Days 1–5)  →  LAUNCH DAY (Day 6)  →  POST-LAUNCH (Day 7+)
Build the foundation       Light the match          Fan the flame

PRE-LAUNCH: Days 1–5

Day 1 — Landing Page Checklist

Your landing page has one job: convert a skeptical stranger into a believer in under 10 seconds.

Above the fold (must-haves):

• Clear headline — outcome-first, not feature-first
• Sub-headline — one sentence explaining how it works
• Hero image or product screenshot (not a stock photo)
• Primary CTA button — one action only (no two CTAs above fold)
• Social proof indicator — "Join 200+ founders" or "As seen in..."

Body content:

• Problem section — agitate the pain they already feel
• Solution section — explain your approach simply
• Features → Benefits translation (never list features without the "so that you can...")
• 3–5 testimonials or early user quotes
• FAQ section addressing top 3 objections
• Second CTA at bottom

Technical:

• Mobile responsive — test on real device, not just browser resize
• Page loads under 3 seconds (test with PageSpeed Insights)
• favicon set
• Open Graph image set (for social sharing preview)
• SSL certificate active (HTTPS)
• Custom domain connected (not a Carrd subdomain)

Day 2 — Analytics Setup Checklist

You can't improve what you can't see. Set this up before you get any traffic.

Core tracking:

• Google Analytics 4 or Plausible installed on all pages
• PostHog or Mixpanel installed inside the product
• Identify & track these 5 events minimum:
  • page_view — all pages
  • cta_clicked — primary CTA button
  • signup_completed — registration success
  • onboarding_step_X — each onboarding step
  • feature_used — core feature engagement

Funnel setup:

• Conversion funnel created: Landing page → Sign-up → Onboarding → Core action
• UTM parameter tracking enabled for launch channels
• Google Search Console connected to domain

Dashboards:

• Create a launch dashboard showing: daily sign-ups, activation rate, traffic source breakdown
• Set up a weekly email digest from your analytics tool

Tools to use:

• PostHog (product analytics, free tier generous)
• Plausible or Fathom (privacy-first web analytics)
• Hotjar or Microsoft Clarity (heatmaps, session recordings — free)

Day 3 — Payment Readiness Checklist

Stripe setup:

• Stripe account verified (identity verification done)
• Bank account connected and payout scheduled
• Products and prices created in Stripe dashboard
• Webhook endpoints configured for: checkout.session.completed, customer.subscription.updated, invoice.payment_failed
• Test mode checkout tested end-to-end with test card 4242 4242 4242 4242

Pricing page:

• Pricing page live with clear tier breakdown
• Annual/monthly toggle (annual = 2 months free is the standard)
• "Most popular" badge on middle tier
• Money-back guarantee stated clearly
• Accepted payment methods shown

Compliance:

• Privacy policy page live (use Iubenda or Termly to generate)
• Terms of service page live
• Cookie consent banner if targeting EU users (GDPR)
• Tax collection configured (Stripe Tax or Lemon Squeezy handles this)

Alternative to Stripe:

• Lemon Squeezy — handles VAT/tax globally, great for indie founders
• Paddle — best for international SaaS with complex tax needs

Day 4 — Product Readiness Checklist

Core functionality:

• Happy path tested end-to-end (sign up → use core feature → get value)
• Error states handled gracefully (show helpful messages, not raw errors)
• Loading states on all async operations

• Password reset flow working
• Account deletion option exists (required for GDPR)

Onboarding:

• Welcome email sent automatically on sign-up (use Loops, Resend, or Postmark)
• In-app onboarding checklist or tour exists
• Empty states are helpful (not blank screens)
• First "aha moment" reachable within 5 minutes

Support:

• Support email set up (support@product-os.pro)

• Basic FAQ/help docs written (5 articles minimum)

Day 5 — Distribution Prep Checklist

• Send personal DMs to your 20 outreach list

Afternoon (2–6 PM)

• Post a "5 hours in" update with early numbers (transparency = engagement)
• Cross-post to any remaining communities

End of Day

POST-LAUNCH: Day 7+

Day 7 — Review & Respond

• Send a personal email to every person who signed up on Day 1
• Look at session recordings — where are users getting stuck?
• Document top 3 questions you got asked

Week 2 — Activation Focus

• Calculate Day 1 activation rate: % who completed core action after sign-up
• If activation < 40% → fix onboarding before more acquisition
• Schedule 5 user interviews with early sign-ups
• Post a "lessons from Week 1" thread publicly

Week 3–4 — Iterate & Amplify

• Fix top 3 issues discovered from user feedback
• Write a case study from an early win
• Set up referral mechanism (ReferralHero or built-in)
• Start SEO content based on questions users are asking

Launch Day Stack

The One Metric That Matters on Launch Day

Not traffic. Not Product Hunt rank. Not Twitter impressions.

Activated paying users.

A launch with 50 visitors and 5 paying customers beats 5,000 visitors and 0 paying customers every time.

Next Step: Use the GTM Playbook to fill your pipeline before launch day hits.

SEO, AI Visibility & Backlink Strategy

Why This Page Ranks for Checklist Queries

Checklist-format content is one of the highest-performing formats for both Google and AI search engines because:

• It answers "what do I need to do" queries with exact, enumerable steps
• AI assistants (ChatGPT, Claude, Perplexity) pull checklist items directly into answers
• Checklists earn "list snippet" positions in Google — the featured snippet type with highest CTR

Primary AI query this page targets: "what do I need to do before launching a SaaS" and "saas launch checklist"

Backlink Acquisition Strategy

High-impact tactics for checklist pages:

• "Skyscraper" outreach: Find existing "SaaS launch checklist" pages with fewer items. Email the authors: "I expanded your checklist to 50 points — happy to share if useful for your readers."
• Product Hunt submission: Submit this as a free resource on Product Hunt. Checklist posts regularly hit top 5 in the "Resources" category.
• Notion template version: Convert the checklist to a shareable Notion template. Notion templates get hundreds of organic shares and almost always link back to the source.
• Newsletter mentions: Pitch to SaaS-focused newsletters (TLDR Founders, Failory, Indie Hackers digest) — "here's a free resource for your readers."
• Embed in your onboarding: Every user who launches with your help and succeeds becomes a potential referrer of this resource.

Topical authority signal: Build a cluster of interlinked pages around "SaaS launch" — this checklist, the 30-day guide, the GTM playbook, and the first 10 customers post all link to each other, strengthening topical authority for the entire cluster.
