My role
I led the end-to-end development of a custom "Charge Slip" system. By replacing manual processes with an automated enterprise workflow, I restored operational confidence and secured the company’s revenue tracking.
The Challenge
A high-volume parcel operation relied on a fragmented, semi-manual charge slip process to calculate handling and storage fees.As volume scaled across 100+ locations, the system failed to keep pace — leading to inconsistent fee application, operational friction, and an estimated $5M+ in annual revenue leakage.
The core issue wasn’t just interface — it was structural. Every item required an assigned handling type before accurate fees could be calculated, yet the workflow lacked safeguards to enforce completion.
The Solution
Creating AI experiences that are intuitive, reliable, and genuinely useful for people guides my work.
- Digitized fee assignment and validation
- Required handling type completion before finalization
- Enabled individual, batch, or bulk assignment
- Dynamically generated real-time fee summaries
- Prevented slip finalization until all revenue-impacting variables were resolved
My Core Contributions
System Architecture
Defined structural rules ensuring every item carried a validated handling type before fee calculation.
Workflow Engineering
Designed flexible assignment methods (individual, small batch, bulk) to support real-world floor operations.
Revenue Safeguards
Implemented conditional UI states that blocked finalization when items were incomplete.
Cross-Functional Leadership
Partnered with product, engineering, and operations to align business logic with usable interaction design.
The Charge Slip Overview
Revenue Risk to Recovery
The manual Charge Slip process was creating operational friction and $5M+ in annual revenue leakage.I re-architected it into a scalable, automated system that restored accuracy and improved fee transparency.
There was Revenue at Risk
- The team used manual charge slips and calculator-based fee tracking
- There was no real-time summaries or storage fee visibility
- Found disconnected workflows causing ~$5M+ annual leakage
A manual billing workflow was creating negative friction and measurable revenue loss across a $32M operation.
Created Modular Solutions
- I replaced the paper slips with a digital, multi-stage workflow (build → assign → finalize → print)
- I created a flexible system to add multple item and fee assignment, either singual or in bulk
- Added automated fee summaries and surfaced hidden storage fee alerts
Delivered a fully modular, automated system from the ground up that was designed for accuracy, scalability, and high-volume operations.
The Approach & Strategy
- Built a modular, scalable workflow with iterative real-world releases
- Designed dynamic interactions to ensure accuracy and fee transparency
- Collaborated cross-functionally to align on systemic, revenue-focused solutions
Applied system-level thinking to create a workflow that reduced errors, improved team alignment, and enabled strategic decision-making.
The Business Effect
- Eliminated manual fee tallying and reduced errors
- Increased fee transparency and surfaced hidden revenue
- Supported thousands of line items per transaction
Result: Improved operational confidence and strengthened revenue protection at enterprise scale.

Design Phase
Exploring the possibilities
To design a Charge Slip system capable of scaling across small and large facilities, I explored workflows, user interactions, and technical constraints through journey mapping, user flows, wireframes, and prototypes. This process ensured alignment across stakeholders, engineering, and operational teams while surfacing key system gaps.
Journey Mapping
- Mapped end-to-end operational workflows across store and warehouse environments
- Identified happy paths and critical pain point
- Highlighted where errors or bottlenecks typically arise
- Provided stakeholders a holistic view of the entire process
Journey mapping revealed key gaps and inconsistencies in the current workflow, giving both the team and stakeholders a shared understanding of where the system needed improvement.
User Flows / Mapping
- Validated the 4-step Charge Slip process with stakeholders
- Mapped multiple entry and exit points across system states
- Considered cross-device workflows for simultaneous operations

Feature Highlights
The Key Takeaways
The charge slip system required a structured approach: every item needed a defined handling type before fees could be calculated and summarized accurately.
The experience had to balance flexibility in assignment with strict operational safeguards to prevent revenue gaps.
Feature Requirements
- Require handling type for every item before proceeding
- Support individual, batch, or bulk item assignment
- Captured staff insights, pain points, and communication gaps
Designing multiple assignment methods required reducing noise while keeping the most critical information


Unassigned Items
- Start with items unassigned in the charge slip
- Disable fee summary until all items have a handling type
- Allow users to assign items individually or in bulk
The system intentionally blocks finalization to ensure every fee is calculated and accounted for.


Fee SUmmary
- Activate fee summary once all items are assigned
- Handling and storage fees are calculated dynamically
- Enable finalization controls after validation while keeping assignment flexible
The summary acts as both confirmation and safeguard
