SaaS launch checklist (2026): staging to first customers

Launch week is mostly toggles and copy-paste mistakes: wrong webhook URL, analytics on staging IDs, forgot to turn on password reset.

Starters remove a lot of code work; they do not remove the checklist. Use this before you invoice a stranger.

Before launch (staging)

• Confirm signup and login work on a fresh browser
• Verify password reset (if supported)
• Verify onboarding end-to-end (new user → first value)
• Run a “slow network” pass (mobile hotspot is enough)

Billing (the money path)

• Confirm checkout success and cancel flows
• Confirm webhooks point to production
• Test failed payment recovery
• Confirm what happens when a subscription ends

If you’re implementing Stripe, run through webhook delivery, customer portal, and failed-payment handling before inviting real customers.

SEO + social

• Confirm metadata titles/descriptions look good
• Confirm share cards render (Open Graph image)
• Confirm sitemap and robots.txt exist
• Add your domain to Search Console

Support and trust

• Add a support email and contact path
• Publish terms and privacy pages
• Add an FAQ to handle objections

Analytics and monitoring

• Track key events (signup, checkout, activation)
• Capture server errors with stack traces
• Log webhook failures

Day 1 goal: get to “first value”

Your day-one product is not “features.” It’s:

• a user understanding the product
• reaching the first meaningful outcome
• trusting you enough to pay

Templates help you move fast, but a checklist keeps you from moving fast in the wrong direction.
