3 Common Onboarding Mistakes Every Fintech Makes

March 2026 · 7 min read

TL;DR

Same three mistakes appear in nearly every fintech we audit. (1) Asking for too many fields at once, assuming "optional" lets us sneak them in. (2) No progress indicator, so users don't know if they're halfway done or 90% done. (3) Sending marketing emails during KYC, which feels greedy. Here's what works instead.

Mistake #1: The Kitchen Sink Form

What we see: Apps ask for 15+ fields upfront, marking 7 as "optional" and hoping users won't notice. Name, email, phone, address (3 fields), occupation, income bracket, emergency contact, preferences, referral code, etc. On mobile, it's overwhelming.

The psychology: Users see "optional" and think "why is it here if it's optional?" They assume it's required. They get fatigued. They abandon.

What works instead:

  • Separate required from nice-to-have: Ask only what's legally mandatory for KYC. Address? Yes. Emergency contact? Not needed for compliance. Delete it.
  • Progressive disclosure: If the form asks for income, only ask if they select "Self-employed." Don't show it to salaried users.
  • Smart defaults: Pincode auto-fills city and state. Aadhaar data pre-fills name and DOB. Fewer manual entries = faster completion.
  • Two fields per screen (mobile): Instead of one overwhelming form, split into mini-steps. "Step 1 of 5" is psychologically better than seeing all 15 fields at once.

Impact: Clients who reduce mandatory fields from 12 to 7 see 12–18% completion lift. The form feels finite. Users feel hopeful.

Mistake #2: No Progress Indicator

What we see: Users fill in form field after field. No indication of how far they've come. On step 6 of 10, they don't know it. They assume they're halfway. After step 8, they lose faith. "Will this ever end?"

The psychology: Humans find uncertain effort demoralizing. Knowing the endpoint matters.

What works instead:

  • Progress bar: Show "Step 3 of 5" or a visual bar. Both work. Bar is better on mobile.
  • Milestone celebration: After completing KYC step 3, show "Nice! You're 60% done. Next: verify your identity."
  • Estimated time: "This should take 3 minutes." Manage expectations. When reality beats expectations, users feel good.
  • Breadcrumbs: On longer flows, show "Personal Info > Verification > Bank Linking." Users see context.

Data: Adding a progress bar typically reduces abandonment by 10–15%. It's the highest-ROI onboarding fix we've seen.

Mistake #3: Sending Marketing Emails During KYC

What we see: User starts signup. Within 2 hours, they get marketing emails: "Welcome! Check out our latest features!" "Did you know you can set up SIP?" These feel tone-deaf. The user is still trying to activate. Now they're being sold.

The psychology: Marketing emails during onboarding feel exploitative. User hasn't even finished activating, and you're pushing features.

What works instead:

  • Suppress marketing until completion: No promotions, no feature highlights, no newsletters until the account is fully active. Zero marketing emails during KYC.
  • Send targeted onboarding emails only: "Your PAN verification is in progress" or "You're 2 steps away from trading." Purpose-driven, not promotional.
  • Start marketing 7 days after activation: By then, the user is invested. They're not raw. A feature highlight feels helpful, not pushy.
  • Use the activation moment for education: "Your account is ready! Here's how to make your first trade [guide link]." Helpful, not salesy.

Impact: Apps that stop marketing during KYC see 3–5% completion lift. It also reduces unsubscribes by 20–30% (users don't feel bombarded).

Why These Three Matter

Onboarding is a trust moment. Users are making a decision: "Should I sign up for this service?" They're vulnerable. The less friction you create, the more confident they feel. Reducing fields, showing progress, and respecting their attention all signal competence. It makes users feel like they're dealing with a professional, thoughtful app—not a greedy one trying to squeeze data or sell them immediately.

The Quick Fix Checklist

Fix #1: Reduce Required Fields

  • Audit every field. Does the regulator require it? If no, delete.
  • For "nice to have" fields, make them truly optional (not marked required).
  • Add smart defaults (pincode auto-fill, Aadhaar pre-fill).

Fix #2: Add Progress Indicator

  • Add "Step X of Y" text or a progress bar.
  • Estimate time: "Takes about 3 minutes."
  • Celebrate milestones: "You're 50% done! Almost there."

Fix #3: Pause Marketing

  • Suppress all promotional emails until account activation is complete.
  • Send only transactional/onboarding emails: status updates, next-step guidance.
  • Resume marketing 7+ days after activation.

Timeline to Implement

  • Fix #1 (reduce fields): 2–3 days (product + legal review)
  • Fix #2 (add progress): 1 day (frontend only)
  • Fix #3 (pause marketing): 1–2 hours (email/automation tool config)
  • Total: ~1 week to see improvements

These aren't complex changes. They're just common sense applied to onboarding. And yet, they're missing from 90%+ of fintech apps. Implement them and watch your activation rates improve immediately.
