How to Build a SaaS MVP with Lovable

Overview

A SaaS MVP is accounts, one core workflow done well, and a way to pay. Everything else is version two.

Beginner explanation: The most expensive mistake is building lots of features before the data model is right.

Technical explanation: Decide early whether accounts are individual or team-based. Retrofitting multi-tenancy is the single most painful change you can make.

Steps

1. Write down the one job your product does.
2. Design the data model, including ownership and team structure.
3. Build authentication and onboarding.
4. Build the core workflow end to end for one user.
5. Add billing, then dashboards, then everything else.

:::tip If you might ever sell to teams, model teams from day one — even if every team has exactly one member at launch. :::

What to check afterwards

• One user can complete the core workflow start to finish
• Data is correctly isolated per account
• Billing state controls access

Common problems

• Retrofitting teams later. Very expensive.
• Building settings screens before the core loop works.
• No isolation testing. Cross-account data leaks are the classic AI-built SaaS bug.

Where people get stuck

If you have followed the steps and the result still is not right, the fastest path is usually to describe the exact behaviour you expected, the behaviour you got, and any error text, then ask for a fix in one focused follow-up prompt. If that loop is not converging, hand it over.
