We build business apps end-to-end, from requirements to admin panels.

Operations that rely on paper, Excel, and verbal updates tend to create missed inputs, double management, and stalled approvals, which quietly inflate costs. We design and develop business apps that people keep using in the field for internal operations, on-site work, and B2B workflows.

Do any of these sound familiar?

Business apps succeed when you design for the full operational loop (input -> approval -> aggregation -> improvement), not just the build.
Office Chaos Illustration
There are too many Excel files, you cannot tell which one is the latest, and aggregation takes time every time.
Approvals stall, you cannot tell who is blocking them, and you keep going back and forth for confirmations.
Field inputs are delayed, and data gets entered in bulk later.
As staff grows, permissions and operating rules become ambiguous.
With more international staff, training costs and input errors increase.
You have a history of systems that were introduced but not adopted.

Typical work that business apps solve

Business app adoption has the biggest impact in areas where information is scattered, approvals stall, and aggregation is heavy. When you design not only input screens but also admin work (roles, aggregation, master data, logs), Excel does not remain after launch.

Reports, inventory, orders

Reports: daily reports, work logs, photo reports, on-site reporting
Inventory: stocktaking, transfers, variance tracking, location-based inventory
Orders: order entry, shipping instructions, delivery schedules, invoices and documents

Requests, scheduling, inquiries

Requests and approvals: leave, expenses, approvals, follow-up tasks (owner and due dates)
Schedules: visit plans, assignments, change sharing
Inquiries and support history: case tracking, status, visibility into history

Design points for apps that keep getting used

Most apps fail to stick because operational bottlenecks get postponed. We build the following requirements into the design by default.

1

1) Manual-free UI/UX

We create flows that are clear for field and back-office teams. By narrowing fields, navigation, and button placement, we reduce training costs.

2

2) Operational design including the admin panel

We build from day one the management-side operations such as master data, aggregation, CSV export, search, and permission settings.

3

3) Role-based access, approval flows, and audit logs

We design for who can do what and when changes happen, ensuring governance and operational reliability.

4

4) Offline and multilingual support when needed

We design offline input and language switching to match field conditions and staffing, preventing downtime and errors.

Scope of service (one-stop)

By handling every phase from requirements definition to maintenance and operations in one place, we clarify accountability and enable smoother development.

  • Requirement definition (as-is/to-be, priorities, operational rules)
  • UI/UX and screen design (wireframes and prototypes)
  • iOS/Android app development
  • Web admin panel development
  • Backend and database design
  • Release support (store submission when needed)
  • Maintenance and operations (monitoring, OS updates, improvements)

Track record (business apps / e-commerce and platforms)

Business apps deliver results when you design not only the build, but also the operational flow (orders, inventory, payments, notifications, admin panels). We develop C2C direct-sales apps, e-commerce and inventory SaaS, and brand e-commerce sites, including payments, operations, and administration.

Matsuhisa Japan E-commerce Site (brand e-commerce)

A brand e-commerce site that showcases Japanese beauty and tradition, with Japanese/English switching, browsing flows, and legal/support pages.

Issue

To help customers purchase high-quality products with confidence, the site needed trust design (payments, shipping, returns) and information flows (categories and product listings).

Solution

Built category and product listing flows, plus pages required for e-commerce operations, including legal notices, terms, privacy, shipping, returns, and FAQ.

Adoption requirements

Designed visible rules to ease pre-purchase concerns, including credit card payments (VISA/Mastercard/JCB/AMEX/Diners).

Yasai App (producer-to-consumer direct-sales app / C2C platform)

A direct-sales app that integrates matching, chat, notifications, and purchasing between producers and consumers.

Issue

Enable direct sales without expensive store systems, and make it easy for sellers to launch quickly and guide buyers to purchase.

Solution

Unified chat, notifications, and purchase into one flow, optimized for mobile to speed up seller onboarding. Inventory and orders are managed centrally via the admin panel.

Adoption requirements

Designed for multi-device use (iPhone/Android/tablet/PC) so it works both in the field and at home.

Flutter / Firebase / Stripe API, 3 months development.

Link Mall (e-commerce and inventory SaaS for order-to-shipping operations)

An e-commerce platform where you can start selling by sharing a link. Centralizes SNS/email orders and completes registration to shipping notifications on a smartphone.

Issue

Lower the barrier to starting an online shop and run registration, management, and shipping notifications without a PC.

Solution

Centralized SNS/email orders and handled product registration, orders, and shipping notifications on a smartphone. The admin panel unified inventory and billing, with permissions and audit logs for immediate operation.

Adoption requirements

Designed to avoid breakdown in smartphone-centered operations, including admin panel, permissions, and logs for post-sale workflows.

HTML / Tailwind CSS / Flutter / Firebase / Stripe API, 5 months development.

How we work (MVP first, then expand)

For business apps, releasing a minimum set of features and improving in operation is the least risky path.

1

1. Free consultation (Zoom available)

Clarify target operations and issues

2

2. Requirement definition

Confirm Must/Should/Could, plus needs for roles, approvals, and documents

3

3. Rough estimate

Provide a ballpark for cost and timeline

4

4. Screen design (wireframes) -> prototype

Validate usability early

5

5. Development and testing

Implement admin panel, logs, and aggregation

6

6. Release

Start operations

7

7. Improvement and expansion

Add features step by step as adoption grows

Excel operations vs. business app operations

Excel is powerful, but as operations grow, invisible costs rise.

Aspect Excel/paper Business app
Input Entered later, leading to omissions and delays Enter on the spot with required fields to prevent gaps
Approval Often stalls via email or verbal requests Approval flows plus notifications reduce bottlenecks
Permissions Boundaries of sharing are unclear Role-based view and edit control
Aggregation Manual work takes time Automatic aggregation with easy search and filters
Change history Hard to trace who changed what and when Audit logs provide traceability
Adoption If it feels tedious, people revert Minimal UI reduces training cost

Signs it is time to move to an app

Excel has split into multiple files
Approvals stall and you cannot tell who is waiting
Permissions and governance are now necessary
Staff has grown and training costs are rising
Aggregation and re-entry have become fixed costs

Frequently asked questions (FAQ)

Q What needs to be decided to get an estimate?
A If you can share the target operations, users (roles and permissions), approval flow, and required documents or aggregation, we can provide a rough estimate. We can also organize this together in a free consultation.
Q Can you build the admin panel (web) as well?
A Yes. We provide one-stop delivery including the admin panel and backend required for operations.
Q Can you support role-based access, approval flows, and audit logs?
A Yes. We design with governance in mind, including role-based permissions, approval flows, and activity logs (audit logs).
Q Can you integrate with existing Excel files or core systems?
A Yes. We propose the best method for your current setup, including CSV and API integrations.
Q Can the app be used offline?
A We can support it depending on requirements. We design for your field environment.
Q Do you support multilingual use?
A Yes. We design language switching to reduce input errors and training costs.
Q Can we start small?
A Yes. We recommend starting with a minimum feature set and expanding gradually as operations stabilize.

Want to organize your issues and budget in 10 minutes?

Business apps succeed more based on how you operate than just what you build. In a free consultation (Zoom available), we will review your current state and clarify the minimum feature scope and rough cost direction.
