INVENTORY & ORDERS
Inventory Management and Ordering System Development
When one product sells on several channels at once and stock is split between a warehouse and suppliers, stock counts tend to drift and items are more likely to be sold twice. Here are cases of a core system that handles allocation of tens of thousands of stock items and status management from order to shipment, an ordering site for business partners, and ordering for construction sites, and how we approach them.

Common Requests About Inventory Management and Ordering
The hard part of building inventory and ordering systems is the rules, not the screens: which stock to allocate to which order, and when an order may move on to the next status. Here are the requests we hear most often, and how we approach them.
Inventory and Allocation
We review each sales channel’s orders, and a person decides which stock to allocate
Our Approach
When order entry points are split among a wholesale ordering site, Rakuten Ichiba, and your own e-commerce site, the work of checking stock for each order grows in proportion to the number of orders. The more the decisions depend on people, the more likely allocation mistakes become.
In the core business system for a furniture and interior wholesaler, we built a mechanism that collects the orders of multiple shops in one place and allocates them automatically from warehouse and supplier stock. It also automatically calculates an estimate of when each order can ship, based on stock and expected arrivals.
Warehouse stock and supplier direct-ship stock get mixed up, and the counts do not match
Our Approach
Products shipped from your own warehouse and products delivered directly by suppliers differ in both how stock is counted and how shipping is handled. Handling them together in a single table puts the stock counts out of sync and leads to stockouts and items being sold twice.
We separated the management of warehouse stock and supplier stock and prepared a dedicated shipping screen for each. Everything from checking shipping instructions to registering the tracking number can be done in one flow.
Tens of thousands of stock items are moving at once, and status management cannot keep up
Our Approach
One product sells on multiple sales channels at the same time, and expected arrivals change from day to day. If it is unclear when an order may move on to the next status, the handling of exceptions ends up concentrated on particular people.
We decide with you, one by one, the statuses of orders, purchase orders, arrivals, and shipments, along with the conditions for moving on to the next status, exceptions included, before turning them into specifications.
Ordering and Order Management
Our ordering is split across LINE, phone, and fax
Our Approach
When each person places orders in a different way, errors in part numbers and quantities occur and no record remains. Communication about delivery schedules and changes also ends up depending on phone calls and fax.
In the construction site ordering system “Di-ORDER,” we built a mechanism that puts orders into one standard format and lets people place them from a smartphone on site. According to the service website, ordering effort has fallen by 65% and ordering mistakes by 92%.
Our ordering site is hard to use, and we keep having to explain it to new business partners
Our Approach
Usability problems such as having to download all product information before you can find anything, payment by bank transfer only, and a complicated invoice process turn into explanation and support work every time a new business partner comes on board.
For the full redesign of a furniture and interior wholesaler’s ordering service, we introduced a search that narrows results by conditions and lets you download only the products you need, credit card payment, and shorter ordering and billing steps. It was released about five months after we started.
STRENGTHS
How We Can Help with Inventory and Ordering System Development
We put our effort into nailing down the allocation and status rules rather than into the number of screens. Here we describe mainly what we actually did in our case studies.
Nailing Down the Allocation and Status Rules All the Way
What makes an inventory management system difficult is not the number of screens but the logic. We decide completely, exceptions included, which stock is allocated to which order and when an order may move on to the next status, so that the numbers do not drift even when tens of thousands of stock items move across multiple sales channels at the same time.
Connecting Sales Channels, Warehouses, and Suppliers in One Flow
In addition to API integration of stock and orders with Rakuten Ichiba and your own e-commerce site, we prepare dedicated screens for warehouse staff and for suppliers, so that everything from shipping instructions to tracking number registration runs as one flow. We can also integrate with existing core business systems and external e-commerce services.

Building Step by Step, Starting from Where Sales Come In
You do not need to rebuild everything at once. In the furniture and interior wholesaler case, we started with the redesign of the ordering service for business partners. We then set up, one at a time, automatic product information updates, the company’s own e-commerce site, and the sales entry points, and finally built the core business system that takes in everything.

AI That Lets You Check Stock by Talking to It
We built an AI assistant into the core business system: you simply ask a question such as “How many orders did we receive today?” or “Are any products out of stock?” and it looks up the data and answers. For ordering at construction sites, we have also developed a feature that reads a PDF delivery schedule and imports it into the screen.

SCOPE
Features We Cover in Inventory Management and Ordering Systems
We connect everything from receiving orders through allocation, shipping, and billing in one set of data. We can also develop only the parts you need.
Centralized Order Intake
We gather orders from multiple sales channels, such as an ordering site, Rakuten Ichiba, and your own e-commerce site, in one place.
Stock Allocation
We allocate stock to each order automatically, based on warehouse and supplier stock and expected arrivals.
Status Management
We manage the status of orders, purchase orders, arrivals, and shipments under consistent rules.
Shipping and Tracking Numbers
Shipping instructions for warehouses and suppliers, and registration of tracking numbers.
Ordering Site for Business Partners
Product search you can narrow by conditions, downloads of only the products you need, card payment, and invoices.
On-Site Ordering
Ordering from a smartphone and sharing of delivery schedules.
External Integrations
Integration with Rakuten Ichiba, your own e-commerce site, existing core business systems, and accounting and payment services.
Data Migration and Switchover
Migration of existing data and switchover of existing users’ accounts.
HOW TO CHOOSE
Choosing Between an Off-the-Shelf Inventory Management System and Custom Development
You do not need to custom-build everything. The right approach depends on the number of sales channels and warehouses and on the terms for each business partner.
| Situation | Suitable Approach |
|---|---|
| One sales channel and one warehouse, with a standard workflow | Off-the-shelf inventory management or ordering system |
| The same stock is sold on multiple sales channels | Custom development of stock allocation |
| Warehouse stock and supplier direct-ship stock are mixed | Custom development of stock management and shipping flows for each stock type |
| Prices and ordering flows differ by business partner | Custom development of an ordering site for business partners |
| A core business system and an e-commerce site are in place, but the connections between them are missing | Development of only the integration parts |
We compare the options, including cost and timeline, and recommend the one that fits.
FLOW
Our Process for Inventory Management and Ordering System Development
We settle the workflow and rules first, then build out the system in stages, starting where the impact is greatest.
Sort Out the Flow of Orders and Stock
For each sales channel, warehouse, and supplier, we sort out how orders and stock move. We decide which stock is allocated to which order and when an order moves on to the next status, exceptions included.
Once the rules are decided, the required screens follow
Check the Screens with Stakeholders
We organize the information in wireframes and design the screens for each type of user, such as warehouse staff, suppliers, and business partners, confirming them with stakeholders as we go.
Development and Integration
We develop everything, including integration with your core business system and e-commerce site and migration of your existing data. When we are left waiting on requests made to outside parties, we reorder the work so that progress does not stop.
Switchover and Operations
We notify existing users in advance and support them through the switchover of their accounts. After the system goes live, we continue to add features and make improvements.
The full redesign of the ordering service for business partners was released about five months after we started
FAQ
Frequently Asked Questions About Inventory Management and Ordering System Development
Here are the questions we are asked most often before a consultation. Please feel free to ask about anything not covered here.
Can stock counts stay accurate even if we sell the same stock in multiple shops?
Yes. In the core business system for a furniture and interior wholesaler, we prevent stock counts from drifting by collecting orders from across shops in one place and allocating stock to them automatically from warehouse and supplier stock.
Case Study: Core Business System for a Furniture and Interior Wholesaler
Can you handle a mix of warehouse stock and supplier direct-ship stock?
Yes. We have a case in which we managed warehouse stock and supplier stock separately and prepared a dedicated shipping screen for each.
Can you connect it with the core business system or e-commerce site we use now?
Yes. In the redesign of the ordering service, we handled integration with the existing core business system and external e-commerce services as part of the requirements. We also have a track record of API integration of stock and orders with Rakuten Ichiba and companies’ own e-commerce sites.
Case Study: Tsuhan Sozai, an Ordering Service for a Furniture Wholesaler
How should we choose between an off-the-shelf inventory management system and custom development?
If you have few sales channels and warehouses and a standard workflow, an off-the-shelf product lets you get started sooner. If you sell the same stock on multiple sales channels, have warehouse and supplier stock mixed together, or have different terms for each business partner, custom development or development of the integration parts is a better fit. We compare the options, including cost and timeline, and make a recommendation.
How long does development take?
It depends on the scope. The full redesign of an ordering service for business partners was released about five months after we started. We can also proceed in stages, starting where the impact is greatest, instead of rebuilding everything at once.
Can you carry over the data from our current system or spreadsheets?
Yes. In the redesign of the ordering service, we handled the migration of existing data and the switchover of existing users’ accounts. In the case of a company’s own e-commerce site, we also built a mechanism that automatically updates the e-commerce site with product information managed in a spreadsheet.
Can we look up stock and order status by asking AI?
Yes. We built an AI assistant into a core business system: you simply ask a question such as “How many orders did we receive today?” or “Are any products out of stock?” and it looks up the data and answers.
How is the cost determined?
It varies greatly with the number of sales channels, warehouses, and suppliers, the complexity of the allocation and status rules, the number of systems to integrate, and the volume of data to migrate. Before we prepare an estimate, we sort these out together with you.
