The SaaS Launch Checklist: What to Verify Before You Go Live

Launch day should be exciting, not terrifying. Having helped multiple SaaS products through launch, including our own Tittu platform, we have learned that the difference between a smooth launch and a frantic scramble is almost always the checklist you ran the week before. Here is ours.

1. Infrastructure that bends, not breaks

Estimate your launch traffic, then test at three times that. Load testing is cheap; an outage on launch day is not. Verify auto scaling actually triggers, confirm your database connection pool will not exhaust, and know your single points of failure before your users find them.

2. Security before the spotlight

A launch is also an announcement to attackers that something new and possibly unhardened just appeared. Before going live: enforce HTTPS everywhere with HSTS, set a Content Security Policy, enable multi factor authentication on every admin surface, rotate any credentials that touched development machines, and run at least one vulnerability scan.

3. Observability, because you cannot fix what you cannot see

Set up monitoring and alerting before launch, not after the first incident. You want dashboards for error rates, response times and infrastructure health, plus alerts that reach a human at 2 AM. Log aggregation matters too: when something breaks, the answer is in the logs, if you kept them.

4. The recovery rehearsal

Backups you have never restored are hopes, not backups.

Run a full restore drill before launch. Time it. Document it. Know your recovery point objective and recovery time objective, and make sure they match what you promise customers.

5. The boring business essentials

• Billing flows: test every plan, every upgrade path, every failure case, in the live payment environment.
• Transactional email: signup, password reset and receipts must land in inboxes, not spam.
• Legal pages: privacy policy and terms that reflect what you actually do with data.
• Support channel: even a simple shared inbox, staffed and answered.
• Analytics: the events that tell you whether activation is working, wired up from day one.

6. The launch day runbook

Write down who is on call, how to roll back, where status updates get posted, and what the escalation path is. The runbook you never need is a small cost. The runbook you needed but did not have is a long night.
