SaaS launch checklist: what a first visitor hits

On staging you are signed in, your account has a plan, and the emails land in an inbox you read daily. A new visitor has none of that. The pricing page can list a free plan the sign-up form does not offer, so the visitor clicks a free button and finds a card field. The welcome email may still link to the staging domain, so the link opens a page the visitor cannot reach. The first screen after sign-up is empty for someone with no data. Your own test never shows these, because you never see the product as a stranger does.

• Each plan on the pricing page is a choice in the sign-up form, under the same name.
• The free option does not ask for a card unless the pricing page says so before the button.
• The welcome email links to the live domain, and the link opens a page that works from a logged-out browser.
• The first screen after sign-up says what to do next, not an empty table with no text.
• The cookie notice and the legal pages are reachable from the sign-up form, not only the footer.

Someone renames a plan in the app, the marketing site keeps the old name, and the sign-up form offers a plan the pricing page never mentions. Put the two side by side. Count the plans on each, compare the price labels and the trial wording, and read every button. A button that says Start free should create a free account, not open a payment form. If the pricing page lists three plans and the form offers two, pick one list as the source for both.

Signup flow testing

A welcome email, a confirmation link and a password reset are all built from settings. If one setting still points at staging, the link opens a page the visitor cannot reach, or a login for an account that was never created. Check the link domain in every email. Then open each link in a browser that is logged out, because your own browser is logged in and hides the fault. An unverified sender address can land in spam, and the visitor never sees the step you were counting on. Sign up with an address that has never touched the site, and read each email the way a stranger would.

A new account has no projects, no data and no history, so the first screen after sign-up is nearly empty. If staging is full of your own test data, that screen never looks empty to you. A stranger reads an empty table with no text as a broken product unless the screen says what to do first. Check for one clear next action, one button and one sentence that says what happens after the click. A visitor who came to try the product leaves at the first blank screen with no next step.

A checklist and a simulated test cannot tell you whether a charge succeeds, whether a refund goes through, or whether the invoice shows the right tax. Visitors cannot pay with a real card, so a checkout test stops at the payment step, and the report says so. Check billing yourself with a card you own, refund it, and read the invoice email it sends. Support is outside the test too, since whether a person answers on launch day is up to you.

After launch you will change the plans, the trial wording and the welcome email, and each change can reopen a fault you already fixed. Run the same new visitors through the sign-up path after every change, and read the step where each one stopped. Check each preview deploy before its link is shared with the team.
