The Ultimate SaaS Launch Checklist: 47 Things Before You Go Live

01. Introduction

The failures that hurt a SaaS launch are rarely dramatic product bugs. They are a broken Stripe webhook that silently drops a payment, a signup flow with no email verification that lets bots flood the trial pool, or a database with no backup enabled because nobody checked the box. These are boring, and that's exactly why they get missed.

Below are the 47 items we check before any SaaS product goes live, grouped into seven categories so the list is actually usable instead of an undifferentiated wall of tasks.

02. Billing and Subscriptions (7 items)

• Stripe (or your billing provider) is in live mode, not test mode, with live API keys set in production environment variables.
• Webhook endpoints are configured for the production URL and verified with the provider's signature check.
• Failed payment handling (dunning emails, grace periods, and downgrade logic) is implemented, not just the happy path.
• Proration is tested for upgrades and downgrades mid-cycle.
• Tax handling (Stripe Tax or equivalent) is configured for every region you'll actually bill in.
• Invoices and receipts are branded and send correctly to a real inbox, not just a test account.
• Cancellation flow actually cancels at the provider level, not just in your own database.

03. Security and Access Control (7 items)

• All environment variables and API keys are out of source control and in a proper secrets manager.
• Password requirements and rate limiting are enforced on login and signup.
• Multi-factor authentication is available, even if optional at launch.
• Role-based access control is tested for every role the product actually ships with, not just admin and user.
• Row-level security or equivalent tenant isolation is verified, not assumed, for any multi-tenant data.
• HTTPS is enforced site-wide with HSTS enabled.
• A basic security review or audit has been done on the auth flow specifically, since that's where breaches concentrate.

04. Onboarding and Core Product Flow (7 items)

• Email verification is required before full account access, to keep the signup funnel clean.
• The first-run experience gets a new user to their first meaningful action, not a blank dashboard.
• Empty states (no data yet) are designed, not left as a blank white screen.
• Trial-to-paid conversion prompts appear at the right moment, not immediately and not too late.
• Account deletion and data export both work, which is both good practice and a legal requirement in most jurisdictions.
• Every core user flow has been tested by someone who did not build it.
• Mobile responsiveness is verified for at least the core flows, even for a desktop-first product.

05. Infrastructure and Reliability (7 items)

• Automated database backups are enabled and a restore has actually been tested.
• Error tracking (Sentry or equivalent) is wired up and alerting to a channel someone actually monitors.
• Uptime monitoring is configured with alerts, not just a dashboard nobody checks.
• Rate limiting is in place on public API endpoints and auth routes.
• A staging environment exists and mirrors production closely enough to catch config-only bugs.
• Database migrations run cleanly against a production-like dataset, not just an empty local database.
• A rollback plan exists for the deploy itself, not just for data.

06. Legal and Compliance (7 items)

• Terms of Service and Privacy Policy are published and linked from signup, not just sitting in a repo.
• A cookie consent banner is implemented if you serve EU or UK visitors.
• GDPR/CCPA data deletion requests have a defined process, even if manual at first.
• A Data Processing Agreement is available for business customers who ask for one.
• Subprocessor list (Stripe, hosting provider, email provider, etc.) is documented and available on request.
• Refund policy is explicit and matches what support will actually honor.
• Any required industry-specific compliance (HIPAA, SOC 2, etc.) has been scoped honestly against your actual customer base, not assumed unnecessary.

07. Support and Communication (6 items)

• A support channel (email, chat widget, or help center) is live and someone is actually watching it.
• Transactional emails (welcome, password reset, receipt) are tested end to end, not just triggered in a dev environment.
• A status page exists so users have somewhere to check during an incident instead of flooding support.
• An incident response plan, even a simple one, exists for who does what during an outage.
• Changelog or release notes have a home, so users see the product evolving.
• A feedback channel exists that actually routes back to the product team, not a black hole.

08. Analytics and Growth (6 items)

• Product analytics (PostHog, Mixpanel, or equivalent) are tracking the events that actually matter for activation and retention, not everything indiscriminately.
• Conversion funnels (signup to activation to paid) are instrumented so you can see where users drop off.
• Search Console and basic SEO fundamentals are in place if organic search is part of the growth plan, see our SEO services for the technical baseline.
• A referral or affiliate mechanism is either live or deliberately deferred, not half-built.
• Key metrics (MRR, churn, activation rate) have an owner and a dashboard, not just raw data sitting in a warehouse.
• A post-launch review is scheduled for two weeks out, specifically to catch what this checklist missed.

09. How to Actually Work Through This List

A 47-item checklist is only useful if someone actually owns running through it, rather than everyone assuming someone else checked the box. The approach that works: assign each category to a specific person, not a team, run through it two weeks before the intended launch date rather than the day before, and treat anything unchecked at that two-week mark as a blocker for the date, not a nice-to-have.

The categories are ordered roughly by how expensive a failure in that area is. A billing bug or a security gap discovered after launch can mean lost revenue or a breach disclosure. A missing changelog page discovered after launch just means you add it that week. Spend the scarce pre-launch review time on the first two categories especially, since those are the two where a launch-day failure is hardest to walk back gracefully.

Resist the temptation to add a 48th item for every edge case someone raises in the final week before launch. A checklist that keeps growing right up until launch day is a sign the team is trying to eliminate all risk instead of managing it sensibly, and it delays a launch that would otherwise have gone fine. Ship with the 47 items covered, watch the metrics closely in week one, and fix what actually breaks rather than what might theoretically break.

10. The Bottom Line

None of these 47 items are individually difficult. The risk in a SaaS launch is not one hard problem, it's forty small ones that each seem safe to skip until one of them causes a payment to silently fail or a user's data to leak across tenants. Working through a structured list, even an imperfect one, catches most of what a rushed launch misses.

StrattonX Technologies builds and launches SaaS products with this exact checklist baked into every engagement. If you're heading toward a launch date and want a second set of eyes on what might be missing, our SaaS development services team can review your build before you flip the switch.
