Impact

83% conversion improvements

InDebted is a fast-growing start-up focused on expanding into new markets and increasing revenue. To achieve the founder’s vision of becoming the world’s most trusted collections agency, the business needed to find new ways to improve product performance

Some of our clients

Challenge

With $117M locked in active plans but just 9% completed, the challenge was to turn payment plans from a leaky funnel into a growth engine.

My role

Hybrid Product Designer / Acting PM, bridging compliance, engineering, and stakeholders.
I led:

  • Discovery, scoping, and feature design

  • 15 customer interviews (AU + US)

  • Problem framing with Head of Product

  • Translating insights into product direction

Research method and finidings

Explore and understand how we can improve payment plan experience.

👉

User selection criteria and Askable recruitment

  • Moderated interviews (8 AU, 7 US)

  • 45 minutes session

  • Balance between $50 to $250

  • 30 to 90 days aged accounts

  • Afterpay and Klarna customers (BNPL)

  • Customers currently on payment plans

🧠 Key insights

Budget-first
Customers set plans around living expenses, not duration.

Cognitive overload
Too many steps and unclear info → backtracking.

Trust and control
Customers wanted clear obligations and self-service flexibility.

Where the current flow falls short

By analysing customer behaviour and UI patterns, we identified key opportunities to improve the plan setup flow:

  • Guardrails: Some customers created plans lasting over 19 years, highlighting the need for clearer limits.

  • Flow complexity: Amplitude showed drop-off was driven by too many steps in the journey.

  • Backtracking: Customers frequently clicked back and forth, trying different amounts and frequencies a sign the UI wasn’t guiding them effectively.

Learning from MVP

The first release had to cut critical elements like toggles, sliders, and upfront summaries. While it simplified delivery, these tradeoffs limited the impact and the metrics didn’t shift as expected. This highlighted the importance of balancing feasibility with user needs even small compromises in control and clarity can blunt adoption.

Alignment & Architecture Reset

The MVP showed UX fixes weren’t enough.
Through cross-functional workshops, we:

  • Clarified client, regulator, and customer needs

  • Prioritised constraints blocking growth

  • Aligned on a north star vision for scalable payments

With exec backing, we committed to a deep architectural reset.

I partnered with a Staff Engineer and an Engineering Manager, backed by the CPO, to ensure we built a solution that was future-proof and aligned with both client and customer needs. Without this, the existing limitations would have continued to slow growth, block scaling into new regions.

Unlocking New Capabilities

Once the new architecture was in place, we could finally build features the old system could never support. This wasn’t just a UX update it was a future-proof foundation that unlocked entirely new ways for customers to manage payments and for clients to recover faster.

New capabilities included:

  • Tiered settlements – breaking down large balances into structured tiers

  • “Promise to pay” arrangements – scheduling one-off commitments without a full plan

  • Abandoned cart recovery – re-engaging customers who didn’t finish setup

  • Discounts & flash sales – offering time-bound incentives safely

  • Flexible self-service plan management – empowering customers to adjust plans within guardrails

New Payment Plan & Rebrand

Once the new architecture was live and the front end modernised, we enhanced the payment plan experience itself.

We redesigned the flow into a single-screen experience where customers could select and confirm their plan in one place plus updating inDebted brand uplift.

  • This simplified the journey and reduced friction.

  • For first-time users, it could feel overwhelming, but we tracked success and key metrics to balance simplicity with usability.

Wrapping up

This project started as a UX improvement but evolved into a full platform rebuild.

  • From MVP: a modest uplift (+0.9%).

  • Through alignment workshops: a shift to architectural reset.

  • To launch: a scalable, rebranded system that boosted conversion, reduced recovery time, and gave customers more control.

Key learnings


  • Lean design delivers real impact: Each MVP was scoped for fast learning, not just polish

  • Self-service is scalable UX: These tools didn’t just reduce support but strengthen the brand

  • Compliance can drive clarity: Constraints helped us design cleaner, user-initiated flows

This project was one of several key initiatives that helped the business secure multiple successful funding rounds, driving its valuation from $140M to $350M.
