TIMELINE
3 months (Apr 2023 - Jun 2023)
OVERVIEW
Shift allows businesses to manage repayments through installment schedules. However, the edit installments feature was creating confusion and anxiety, especially for customers trying to manage cashflow.
I led the redesign of this experience to make repayment changes clear, predictable, and trustworthy, while aligning with internal system and compliance requirements.

IMPACT
The redesign addressed a core trust gap in how businesses managed their repayments.
-18%
Significant reduction in support calls related to repayment changes
Confidence in self-serve task completion
Ambiguity in repayment impact. Users can see the full financial effect before confirming

PROBLEM
The existing edit installments experience made it difficult for businesses to confidently manage their repayments. Changing installments is a high-stakes action - it directly impacts cashflow, costs, and financial planning. However, the product did not provide enough clarity or reassurance for users to feel in control of these decisions.
Users didn't know if their changes had gone through. There was no clear explanation of what would happen next. The impact on repayments - schedule, cost, and interest - was unclear. Terminology was confusing and inconsistent, and system feedback was delayed or missing entirely.

CONTEXT
Redesign the edit installments experience to:
DISCOVERY
To understand why users were losing confidence, I started with usability testing before any design decisions were made.
The key questions driving the research: why were users hesitating at the point of confirmation, what information did they need to feel confident making a change, and where was the system failing to communicate what had happened and what would happen next.
KEY FINDINGS
The absence of real-time feedback and confirmation eroded trust, prompting unnecessary calls to customer support. Users would repeat actions or abandon the flow entirely rather than risk making an error.
KEY FINDINGS
Users struggled to understand how a deferred payment would affect their schedule, total cost, and interest over time. Without visibility of the financial implications upfront, making a change felt like a risk rather than a choice.
CONSTRAINTS
Designing within this space meant working around fixed requirements from compliance, engineering, and the nature of financial data itself - none of which could be simplified away.
Compliance owned what messaging had to appear and when. Engineering was responsible for backend services that introduced latency and inconsistent states. The financial data itself had to be accurate to the cent; any mismatch between what the UI showed and what the system calculated was a compliance and trust risk.
Getting the redesign right meant all three were embedded in the process from the start.

Repayment changes required strict validation. Messaging had to accurately communicate financial implications - cost, interest, and schedule - at every stage.

Repayment calculations depended on multiple backend services running sequentially. This caused latency and inconsistent system states that the UI had to account for.

Any errors in how repayment impacts were displayed could affect customer trust and create compliance risk. The UI had to reflect real financial outcomes, not approximations.
RESEARCH
Usability testing quickly exposed why users were feeling anxious about the edit installments process. People weren't sure if their changes had gone through, what would happen next, or how adjustments would affect their payments.
Terminology was confusing, and poor system feedback led to hesitation or calls to customer support. The sessions made it clear this wasn't just a UX flaw - it was a trust issue. The fix would be about restoring confidence through clearer messaging and real-time feedback.
RESEARCH
Through a series of internal workshops, I unpacked user feedback to understand what really mattered to business owners needing to pause or adjust repayments. Many were dealing with unpredictable cashflow and wanted flexibility without feeling penalised or unsure of the impact.
Insights from each session were grouped by theme - what triggered a change request, what information users needed before confirming, where feedback was missing or misleading, and what language was causing confusion.
Surfacing these patterns helped build a shared understanding of the problem before any design decisions were made.
RESEARCH
Mapping the existing experience made it clear that the anxiety wasn't caused by a single point of failure. Users were being asked to make financially significant decisions with almost no information about the consequences, and with no confirmation that the system had registered what they'd done.
The opportunity was to give users sight of the financial impact before they committed, and clear confirmation that their change had been processed. Both could be achieved within the existing compliance and system constraints. It was a design problem, not a technical one.
RESEARCH
To address the complexity of the existing edit installments flow, I created detailed journey maps that captured every step, decision point, and system interaction within the process.
By mapping the journey across key states - request initiation, eligibility check, schedule recalculation, confirmation, and follow-up - I identified where users were losing confidence and where systems were introducing unnecessary friction. The maps were refined closely with engineering to align with existing notification and repayment frameworks, ensuring technical feasibility and consistency.
DESIGN
The research pointed to a clear design direction: users needed to understand what would happen before they committed to a change, and they needed confirmation that it had worked after. Neither of these required removing compliance requirements or restructuring the backend - they required better communication at every stage of the flow.
The redesign focused on three things: making the financial impact of a change visible upfront, introducing real-time system feedback throughout the flow, and simplifying the language so users could act with confidence rather than anxiety.
DESIGN
The most significant design decision was introducing a side-by-side comparison that allowed users to see the full financial impact of their installment change before confirming - current schedule versus proposed schedule, repayment amounts, and interest figures presented in a clear, scannable layout.
This removed the ambiguity that had previously caused hesitation. By making the financial implications visible upfront, users could assess the change, understand what it meant for their cashflow, and proceed with confidence. Early testing showed a noticeable reduction in uncertainty and a marked improvement in task completion rates.

DESIGN
Implementing the redesigned journey highlighted gaps in the existing component library. Notifications, progress indicators, and status messages lacked the flexibility to support the richer feedback states the new flow required.
I initiated an update to the library, introducing new variants for banners, inline alerts, and confirmation patterns that could scale across both web and native platforms. This work formed part of a broader design language refresh - modernising the visual system, tightening typographic hierarchy, and unifying interaction behaviours across the product.



DESIGN
Analysis of user behaviour showed that a significant proportion of customers accessed their accounts while away from a desk - travelling, on site, or during short breaks. Repayment changes were often prompted by immediate cashflow needs rather than planned sessions at a laptop.
To support this, the redesigned experience was fully responsive and mobile-optimised. The side-by-side comparison adapted to a tabbed layout on smaller screens. Interactive elements were refined for touch input, with increased hit areas, improved spacing, and mobile-friendly feedback states.

IMPACT
The redesigned experience significantly improved both user confidence and operational efficiency, addressing a core trust gap in how businesses managed their repayments.
Users were able to clearly understand the impact of their changes before committing, which removed uncertainty at critical decision points. Support call volume for repayment-related queries fell as the self-serve route handled cases that had previously required a human handoff.
Beyond the immediate outcomes, the redesign established a pattern for handling complex financial interactions clearly and transparently. The updated component library and journey framework created a foundation for scaling other self-serve financial capabilities; reducing long-term reliance on manual processes and giving the product team a consistent system to build on.
KEY LEARNINGS
Users don't need simpler decisions - they need better information. Showing the full financial impact of a change upfront removed anxiety without reducing user control.
KEY LEARNINGS
Every regulatory requirement was preserved. The redesign worked within the constraints, not around them - better communication, not fewer rules.
KEY LEARNINGS
The backend complexity was real, but the user's experience of it was a design choice. Real-time feedback and clear confirmation states transformed a technically complex flow into a predictable one.
REFLECTION
This project was less about inventing new patterns and more about getting the fundamentals right. The flows existed. The backend worked. The compliance requirements were clear. What was missing was the layer of communication that made users feel in control - confirmation that things had worked, visibility of what they were agreeing to, and language that meant something.
The component library work was a natural extension of that thinking. Fixing the journey exposed the gaps in the system, and addressing those gaps meant the next feature built on Shift's platform would start from a stronger foundation.
The latency introduced by sequential backend services is still an issue - users still experience a delay between action and confirmation that a loading state partially addresses but doesn't fully resolve. Reducing that dependency on sequential processing is the next engineering and design problem worth solving.
