Your SaaS first version: what to build first and what to leave out

How to scope the first version of a SaaS product around one core job, with sign-up, billing and an admin panel, so you can launch in weeks rather than months.

Most SaaS products that stall do not fail because they are missing features. They stall because they took too long to reach real customers. A good first version does one job well, charges for it and gives you a way to run the business behind it.

Start with one core job

Write down the single thing a customer will log in to do. Not three things, one. Everything in version one either helps with that job or helps you get paid for it.

What version one needs

Sign-up and onboarding that gets a new user to the core job in minutes.
The core feature, built properly.
Subscription billing with monthly and yearly plans and trials, through Stripe or PayPal.
A customer dashboard with their data and settings.
An admin panel for customers, plans, payments and support.
Emails: welcome messages, receipts and failed-payment reminders.

What to leave out

Complex team roles, unless the product only makes sense for teams.
More than one integration. Pick the one customers ask for most.
Native phone apps. An installable web app is enough to start.
Advanced analytics. Sign-ups, active accounts and revenue are enough at first.

Launch, measure, then grow

Once customers are paying, their requests become your roadmap. Watch where people get stuck during onboarding, which features they use every week, and why cancellations happen. Build the next feature from that, not from a wish list.

A real example

Services Rhône-Alpes is a SaaS platform for professionals in the Rhône-Alpes region: a professional network and business directory with professional accounts, subscription plans, payments, services, content and AI features, all in one custom platform with one admin panel.

Questions people ask

How long does the first version of a SaaS take?

Usually a few weeks, when it is scoped around one core job.

Which payment provider should a SaaS use?

Stripe or PayPal both handle subscriptions, trials and automatic retries for failed payments.

When should I add team accounts?

When customers ask for them, unless your product only works for teams.

Key takeaways

Build version one around a single core job.
Include sign-up, billing, a dashboard and an admin panel from day one.
Let paying customers decide what comes next.
