Systems that fit how you work today, starting with your workflow
Every company manages orders, inventory, customers, and projects in its own way. Bending your operations to fit an off-the-shelf package can end up creating more manual work, not less. RG looks closely at how your work flows today, then designs and develops a business system that fits it.
Re-keying orders that arrive by fax into a system by hand. Several people updating Excel ledgers until no one knows which version is current. We replace everyday tasks like these with systems, without forcing change on your team. We can also propose keeping your current accounting software or core systems and connecting them via CSV or API.
You can talk to us even before your requirements are settled. Consultations and estimates are free. The person who first hears your requirements goes on to handle design and development.
/ Services
01
Records from order intake to shipping, inventory levels, supplier and customer information, project status — we build systems that let you manage the information you handle every day in one place. The input fields and screen layout are designed around your operations.
02
We replace paper slips, Excel ledgers, and work handled by fax or phone with web screens for entering and checking information. If it's hard to ask your business partners to change how they send orders, we can keep the way you receive them as is and systematize only your internal processing.
03
We keep the core systems and accounting software you use today and build mechanisms to exchange data with them via CSV files or APIs. After checking the specifications of the systems involved, we propose how much double entry can be eliminated.
04
We build the admin panels your staff use behind customer-facing services and websites. We also build in what you need to use them safely in-house, such as limiting what each role or department can see and logging who did what and when.
05
Rather than replacing everything at once, we propose systematizing the operations with the biggest pain points first. You can also run the old and new systems side by side for a while and switch over once your team is comfortable.
06
A business system really proves itself once it's in use. Under a monthly maintenance and operations contract, we keep handling bug fixes, changes to keep pace with your business, server management, and more.
/ Why RG
The person who first hears your requirements goes on to design and develop the system. Requirements don't get lost between sales and engineering, and you never have to re-explain the finer details of your operations along the way.
We don't jump straight into screens and features. Together we confirm who uses which information and when, and separate what should become a system from what people should keep doing. Then we build only the features you really need.
We plan and run our own products, including the order automation service Flux. We know firsthand what happens after launch and what causes trouble in day-to-day operations, and we bring that experience to the design of your system.
We can hold meetings and exchange documents in Japanese, English, or Korean. Talk to us if your work involves overseas business partners or if you need multilingual screens for international staff.
/ Process
STEP 01
We start by hearing what's causing trouble today. If you have forms, Excel files, or system screens you use, showing them to us speeds things up. It's fine if your requirements aren't settled. Consultations are free.
STEP 02
We diagram your workflow and decide with you what to systematize and what to leave as manual work. We then present the scope, approach, and an estimate. For large systems, we also propose a phased approach.
STEP 03
We settle the screen flow and how data is structured before starting development. During development, we show you working screens to check usability and adjust as needed.
STEP 04
We migrate data from your existing Excel files and systems to the new system, and you start using it in daily operations. If needed, you can run it alongside your current way of working for a while and switch over once you've confirmed everything works.
STEP 05
Many improvements only become apparent after you start using the system. Under a monthly maintenance and operations contract, we keep fixing bugs, adding features, and adjusting the system as your business changes.
/ Pricing
Cost depends on the number of features and screens, the systems to be integrated, and whether data migration is needed. Once we've heard about your project, we provide a free estimate tailored to it. You can choose from three contract types: a fixed-price contract, a monthly maintenance and operations contract, or technical advisory.
All prices exclude consumption tax.
/ Examples
An order automation service for wholesalers and distributors. AI reads orders that arrive by fax, phone, or order chat, and matches them against the product master to create order data. A person makes the final check, and confirmed data can be passed to existing systems as CSV. It can be introduced without changing how your customers order or your phone numbers. A pilot deployment with a food wholesaler began in October 2026.
In 2026, we began developing a web ordering system with a client whose business serves aesthetic clinics. The system is designed to let each clinic order at its own prices, and to let the supplier confirm orders and export them as CSV. Our relationship with this client began around 2024 with building their website.
Since 2022, we have worked on a marketing technology company's CDP product. We have handled everything from building the processes that ingest and shape data (ETL workflows) to data platform design consulting and operations.
/ FAQ
Yes. It's fine to come to us at the stage of "we want to fix this task." We'll learn about your current workflow and work out with you what to systematize. Consultations and estimates are free.
It varies greatly with the scope and the systems to be integrated, so there's no single answer. Once we've mapped your workflow and the scope is clear, we give you an estimated timeline along with the quote. If some operations are urgent, we can also discuss building those parts first.
Mainly by the number of screens and features, the systems to be integrated, the amount of data to migrate, and the scope of maintenance after launch. Starting with what you need and expanding gradually can make costs easier to plan than building big from the start.
We propose integration by exchanging data via CSV files or APIs. What is possible depends on the specifications of the system you're connecting to. If you tell us which systems are involved and what data they can export, we'll look into it and propose an approach.
No. We can replace operations one at a time, starting with the biggest pain points. You can also switch over gradually while running the new system alongside your existing ones.
Yes, you can ask us about data migration as well. The effort depends on the volume of data and how consistently it was recorded, so we look at the actual files before explaining the approach and cost. For paper records, we decide together how much to re-enter.
Yes. Under a monthly maintenance and operations contract, we handle bug fixes, changes to keep pace with your business, server management, and more. Because we developed the system, we handle maintenance directly, and you never have to re-explain the background from scratch.
There are three: a fixed-price contract, a monthly maintenance and operations contract, and technical advisory. You can combine them, for example a fixed-price contract for development followed by a monthly contract after launch. We also take on technical consulting alone for teams developing in-house.
/ Contact
You don't need a finished spec. Tell us about the problem you're facing, and we'll propose an approach and a rough estimate. Consultations and estimates are free, and we usually reply within one business day.
