Transform inventory management from the field. An app that replaces Excel and "sticks".

Inventory management is prone to discrepancies, increased search time, and stock shortages/surpluses when input delays, manual transcription, and dependency 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 only \"built\". That's why we incorporate \"sticking points\" such as manual-free UI/UX, authority/audit logs, offline support, and multilingual capabilities into the design from the start, creating inventory management that continues to be used.

Common Problems in Inventory Management (Limits of Excel)

Inventory seems like a "numbers" problem, but in reality, it is a problem of operations (input, authority, approval, history). In other words, inventory management is not just "keeping stock numbers"; it requires a design that tracks who moved what, when, and why.

Excel files split into multiple versions, making it unclear which is the latest.

Field staff cannot input data on the spot, leading to batch transcription later and increased discrepancies.

Inability to track causes of changes, cannot explain why stock moved.

Unclear authority and rules as locations and personnel increase.

Input stops in weak signal areas.

Increased education costs and input errors due to more foreign staff.

What Inventory Apps Can Do

Inventory management apps are most effective when they allow the Inbound/Outbound -> Transfer -> Stock Counting -> Discrepancy Handling cycle to be completed via "field input".

Inbound/Outbound (Entry/Exit Management)

Input on the spot -> Immediately reflected on the admin panel

Input flows designed to reduce errors (mandatory fields, candidate selection, minimal 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 -> Acceptance)

Stock Counting (Inventory App)

List stock counting targets, automatically calculate discrepancies

Record reasons for discrepancies (damage, loss, misinput, 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 is meaningless if it is not used on-site. Common failure patterns and avoidance strategies are organized below.

1) Manual-free UI (Don't underestimate education costs)

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

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

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

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 + automatic sending when reconnected (retry queue) as a prerequisite.

4) Multilingual Support (Reduce errors and shorten training)

Just having language switching reduces input errors and education costs. We integrate multilingual support as needed.

Service Scope (App + Admin + Backend 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 a single batch. Development mainly uses Flutter to build iOS/Android with the same codebase, suppressing costs, duration, and subsequent management costs.

Excel Inventory vs Inventory App

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

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

Signs it's time for an app

Excel files divided into multiple versions

Cannot explain inventory discrepancies (reasons not recorded)

Transcription has become the norm due to weak signal areas

Places/people increased, need 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 (Inbound/Outbound / Stock Counting / Transfer / History), users and authority, necessity of approval, and required aggregation/output at 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 a one-stop manner.

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 automatic sending when reconnected (retry queue) as a prerequisite.

Q Is multilingual 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 quotas for minor modifications.

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

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