3 Mistakes to Avoid When Designing Your First SaaS Product

3 Mistakes to Avoid When Designing Your First SaaS Product - a screen on the left of a cluttered Dashboard, and on the right a clean UI homepage

Designing your first SaaS product? These early-stage mistakes can kill clarity, overwhelm users, and hurt conversion. Here’s what to watch out for — and how to avoid them.


1. 🎯 Designing for Yourself (Instead of Your Users)

You're not the user.
Founders and teams often design for what they like, not what real users need.

Try to explain how to use your site. Screens of a flow that shows how the tool can be used

🚫 Why it's a mistake:

  • Skips user validation
  • Assumes too much prior knowledge
  • Ignores the real workflow pain points

✅ What to do instead:

  • Talk to users early and often
  • Let qualitative and quantitative feedback shape the UI
  • Watch real usage, not just opinions
💥
Pro Tip: Use tools like Maze or Hotjar to collect feedback and improve before scaling.

2. 🚪 Skipping Onboarding

No context = fast churn.
Users judge your product in the first few minutes, so don’t make them guess.

First-time users need guidance and a proper on-boarding - screens onboarding new users to the app

🚫 Why it’s a mistake:

  • New users get lost or frustrated
  • Feature value is never surfaced
  • Creates friction when you need trust

✅ What to do instead:

  • Use progress bars, checklists, or tooltips
  • Offer optional guided tours
  • Explain the value while the user takes action
💥
Pro Tip: Think of onboarding as a conversation, not a tutorial.

3. 🧱 Overloading the Interface with Features

More ≠ better.
Trying to “prove value” with lots of features? You might just confuse users.

Don't overload your product with features - screen on the left with the overwhelming dashboard, and a screen on the right with a clear user interface

🚫 Why it’s a mistake:

  • Dilutes your product’s main purpose
  • Makes UI harder to navigate
  • Slows down onboarding and retention

✅ What to do instead:

  • Start with one clear job-to-be-done
  • Design around that task first
  • Only add features once real users ask for them
💥
Pro Tip: Ask yourself: “What’s the one thing the user came here to do?”
