Transform Inventory Management from the Field. An App that Replaces Excel and "Sticks".

Inventory management is prone to mismatches, increased search time, and shortages/excess stock when input delays, manual transcription, and reliance on specific individuals accumulate.

Finite Field designs and develops iOS/Android compatible apps + easy-to-operate admin panels for inventory operations in construction, logistics, and manufacturing.

Field DX (Digital Transformation) often fails if it's just "built". That's why we incorporate "sticking points" like manual-free UI/UX, authority/audit logs, offline support, and multi-language capabilities into the design from the start, creating inventory management that continues to be used.

Common Issues in Inventory Management (Limits of Excel)

Inventory seems like a "numbers" problem, but in reality, it's an operation (input, authority, approval, history) problem. In other words, inventory management isn't just about "holding stock numbers"; it requires a design that tracks who moved what, when, and why.
Inventory Issues Illustration
Excel files split into multiple versions, making it unclear which is the latest.
Field staff can't input data on-site, leading to batch transcription later and increased discrepancies.
Cannot track reasons for changes, unable to explain why stock moved.
Ambiguous authority and rules as locations and staff increase.
Input stops in areas with weak signal.
Increased educational costs and input errors due to more foreign staff.

What Inventory Apps Can Do

Inventory management apps are most effective when they enable the cycle of In/Out -> Transfer -> Stocktaking -> Discrepancy Handling to be completed via "field input".

Inbound/Outbound (In/Out Management)

Input on-site -> Instantly reflected in the admin panel
Input flows designed to reduce errors (required fields, candidate selection, minimum steps)

Stock Transfer (Between Locations/Sites)

Log history of what moved from where to where and when
Design according to operations, such as transfer status (Instruction -> Execution -> Receipt)

Stocktaking (Stocktaking App)

List stocktaking targets, automatically calculate discrepancies
Record reasons for discrepancies (damage, loss, wrong entry, etc.) for improvement

Visualization of Stock Trends, Discrepancies, History (Admin Panel)

Check stock trends, discrepancies, and history on the admin panel
Design logs for audit and control (who did what)

Design Requirements for "Sticky" Inventory Management (Failure Avoidance Checklist)

Even if an inventory app is introduced, it's meaningless if not used on-site. Common failure patterns and avoidance strategies are organized below.

1

1) Manual-Free UI (Don't Underestimate Education Costs)

If the UI is difficult, the field will eventually return to paper or Excel. We limit buttons, input items, and flows to design a system where frequently used operations can be done without hesitation.

2

2) Authority Design + Approval Flow + Audit Logs (Inventory Needs "Control")

Without roles or approval flows, risks of input errors and data tampering remain. We design viewing/editing permissions and operation logs for each role, creating a system that management can operate with peace of mind.

3

3) Offline and Retry Queue (Field Operations Don't Stop)

If input is impossible in weak signal areas, transcription work returns, leading to double management. We design with offline input + auto-send on reconnection (retry queue) as a prerequisite.

4

4) Multi-Language Support (Reduce Errors and Shorten Training)

Just having language switching reduces input errors and education costs. We incorporate multi-language support as needed.

Scope of Service (App + Admin + Backend in One Stop)

Inventory management doesn't work with "just an app". Master management, authority settings, history checks, aggregation/output, and other management tasks remain. We handle the following in one batch. Development mainly uses Flutter to build iOS/Android with the same code base, suppressing costs, duration, and subsequent management costs.

  • iOS/Android App Development
  • App Design
  • Web Admin Panel Design
  • Server/Database Design

Achievements (System Development Including Inventory & Operations)

Inventory management yields results when designed to include operations where stock moves (Orders, Shipping, Billing, History), not just "stock numbers".

Link Mall (EC/Inventory Management & Order-to-Shipment SaaS)

Centralized orders via SNS/Email, completing product registration, ordering, and shipping notifications on a smartphone. Centralized inventory and billing on the admin panel, equipped with authority and audit logs for immediate operation.

Issue

Lower hurdles for starting an online shop, enabling operations from 'registration, management, to shipping notification' without a PC.

Solution

Centralized orders via SNS/Email, completing operations on a smartphone.

Requirement

Equipped with authority and audit logs for immediate operation.

Duration: 5 months / Tech: HTML, Tailwind CSS, Flutter, Firebase, Stripe API

Member-Only EC & Order Management System (Stock History & Auto-Deduction)

Designed to complete order-related operations including product/inventory management, estimates, orders, and billing in one system.

Issue

Improve inventory accuracy and link with orders.

Solution

Built a mechanism to check stock change date/time, amount, and quantity before/after change, and automatically deduct stock upon order receipt.

Requirement

Visualization of stock changes and automatic deduction.

Car Delivery Field (Example of Business Management App Including Inventory)

Organized inventory management, customer information management, and sales process records into one app, allowing business data to be checked and updated from anywhere via smartphone.

Issue

Check and update business data from anywhere.

Solution

Centralized management with a smartphone app.

Requirement

Mobile support.

Development Process (MVP -> Field Intro -> Phased Expansion)

For inventory management, intro with minimum features -> improve while operating is a process less likely to fail than building everything from the start.

Duration & Cost Estimates (Model Case)

Inventory management systems vary by requirements, but please refer to the following model cases and AI auto-estimate standards as a guide.

AI Auto-Estimate (Screen Unit Price Guide)

Mobile: ¥60,000/screen Web: ¥40,000/screen Guide for getting a rough idea.

The above is a rough estimate. After a hearing, we will create a rough estimate for free within 24 hours.

Excel Inventory vs Inventory App

Excel is excellent, but for inventory, which requires "field input" and "history/control", costs tend to balloon as operations increase.

Aspect Excel Operation Inventory App Operation
Input Batch transcription -> Delays/Omissions occur Input on spot, suppress omissions with required fields
History Hard to track why it moved Easy to track with change history/operation logs
Control Ambiguous sharing boundaries Stable operation with role-based authority/approval
Location Files easily split Easy centralized management by location/staff
Environment Input stops with weak signal -> Transcription returns Hard to stop with offline input + retry
Aggregation Time-consuming manual work Easy auto-aggregation, search, and filtering

Signs it's time for an App

Excel files are split into multiple versions
Cannot explain stocktaking discrepancies (reasons not recorded)
Transcription is normalized due to weak signal areas
Locations/People increased, needing authority and control

FAQ

Q What needs to be decided for a rough estimate?
A A rough estimate is possible if we know the scope (In/Out / Stocktaking / Transfer / History), users and authorities, necessity of approval, and required aggregation/output on the admin panel.
Q Can you handle the Admin Panel (Web) as a set?
A Yes. We handle everything from the admin panel required for operations to the backend in one stop.
Q Can you handle authority management, approval flows, and audit logs?
A Yes. We incorporate role-based authority, approval flows, and operation logs (audit logs) into the design.
Q Can it be used in offline environments?
A Yes. We design with offline input and auto-send upon reconnection (retry queue) as a prerequisite.
Q Is multi-language support possible?
A Yes. We can prepare language switching to suppress input errors and education costs.
Q Can we request maintenance and operation?
A Yes. We design according to your operation plan, such as OS update support, monitoring/backup, failure response, and minor modification quotas.

Why not sort out inventory issues and budget in 10 minutes?

Inventory management differs more in "Operations (Input, Authority, History)" than "Stock Numbers". In a free consultation (Zoom available), we will sort out the scope of minimum features and direction of rough costs based on your current situation.
